Validation data

Figure 1. ChIP results obtained with the Diagenode antibody directed against p53
ChIP assays were performed using human U2OS cells, treated with camptothecin, the Diagenode antibody against p53 (Cat. No. C15410083) and optimized PCR primer sets for qPCR. ChIP was performed on sheared chromatin from 4 million cells. A titration of the antibody consisting of 1, 2, 5, and 10 µg per ChIP experiment was analysed. IgG (2 µg/IP) was used as negative IP control. qPCR was performed with primers for the p21 and GAS6 genes used as positive controls, and for GAPDH promoter and the Sat2 satellite repeat, used as negative controls. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).

Figure 2. ChIP-seq results obtained with the Diagenode antibody directed against p53
ChIP was performed on sheared chromatin from 4 million U2OS cells using 1 µg of the Diagenode antibody against p53 (Cat. No. C15410083) as described above. The IP’d DNA was subsequently analysed on an Illumina HiSeq. Library preparation, cluster generation and sequencing were performed according to the manufacturer’s instructions. The 51 bp tags were aligned to the human genome using the BWA algorithm. Figure 2 shows the peak distribution along the X-chromosome (fig 2A) and in 3 genomic regions of chromosome 6, 13 and 12, surrounding p21 (CDKN1A), GAS6 and MDM2, 3 known targets genes of p53 (fig 2B, C and D, respectively).

Figure 3. Determination of the antibody titer
To determine the titer of the antibody, an ELISA was performed using a serial dilution of Diagenode antibody directed against human p53 (Cat. No. C15410083), in antigen coated wells. By plotting the absorbance against the antibody dilution (Figure 3), the titer of the antibody was estimated to be 1:308,000.

Figure 4. Western blot analysis using the Diagenode antibody directed against p53
Nuclear extracts of HeLa cells (40 µg) were analysed by Western blot using the Diagenode antibody against p53 (Cat. No. C15410083) diluted 1:2,000 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is indicated on the right; the marker (in kDa) is shown on the left.
Target Description
The transcription factor p53 (UniProt/Swiss-Prot entry P04637) is a tumour suppressor that regulates the cellular response to diverse cellular stresses. Upon activation, p53 induces several target genes which leads to cell cycle arrest and DNA repair, or alternatively, to apoptosis. In unstressed cells, p53 is kept inactive by the ubiquitin ligase MDM2 which inhibits the activity and promotes the degradation. Mutations in p53 are involved in a vast majority of human cancers.

RRAD, IL4I1, CDKN1A, and SERPINE1 genes are potentially co-regulated by NF-κB and p53 transcription factors in cells exposed to high doses of ionizing radiation.
Szołtysek K, Janus P, Zając G, Stokowy T, Walaszczyk A, Widłak W, Wojtaś B, Gielniewski B, Cockell S, Perkins ND, Kimmel M, Widlak P
BACKGROUND: The cellular response to ionizing radiation involves activation of p53-dependent pathways and activation of the atypical NF-κB pathway. The crosstalk between these two transcriptional networks include (co)regulation of common gene targets. Here we looked for novel genes potentially (co)regulated by...

The Alzheimer's disease-associated TREM2 gene is regulated by p53 tumor suppressor protein.
Zajkowicz A, Gdowicz-Kłosok A, Krześniak M, Janus P, Łasut B, Rusin M
TREM2 mutations evoke neurodegenerative disorders, and recently genetic variants of this gene were correlated to increased risk of Alzheimer's disease. The signaling cascade originating from the TREM2 membrane receptor includes its binding partner TYROBP, BLNK adapter protein, and SYK kinase, which can be activated ...

<p><small><strong>Figure 2. ChIP-seq results obtained with the Diagenode antibody directed against p53</strong><br /> ChIP was performed on sheared chromatin from 4 million U2OS cells using 1 &micro;g of the Diagenode antibody against p53 (Cat. No. C15410083) as described above. The IP&rsquo;d DNA was subsequently analysed on an Illumina HiSeq. Library preparation, cluster generation and sequencing were performed according to the manufacturer&rsquo;s instructions. The 51 bp tags were aligned to the human genome using the BWA algorithm. Figure 2 shows the peak distribution along the X-chromosome (fig 2A) and in 3 genomic regions of chromosome 6, 13 and 12, surrounding p21 (CDKN1A), GAS6 and MDM2, 3 known targets genes of p53 (fig 2B, C and D, respectively). </small></p>

In addition, chitosan nanoparticles (CNPs) were used to encapsulate this macromolecular complex, targeting enhancing its therapeutic effect and minimizing its side impacts. The encapsulated Ag(I) complex was significantly triggered apoptosis (P &lt; 0.05) with much more rapidly release of Ag(I)FLLL49-GbA from the CNPs at pH 5.3 than at pH 7.4, which is beneficial for cancer-targeted drug delivery. Free complex showed promising ability in preventing glucose uptake and lactate production coupled with cellular ATP depletion in cancer cells. Additionally, there was significant decrease in the inflammatory cytokines in breast cancer (MCF-7) and lung cancer (A549) cells with values of P &lt; 0.01 and P &lt; 0.001 after 24 h incubation. Furthermore, the death-inducing proteins have been significantly up-regulated (P &lt; 0.01 to P &lt; 0.001) after 36 h incubation of cancer cells. Consequently, the novel curcuminoid macromolecule showed significant feasibility in triggering the high expression of apoptotic caspases caspase 3, caspase 8, P53, and Bax (P &lt; 0.01 to P &lt; 0.001) after 48 h of chemotherapy. Noteworthy, the cytotoxicity of Ag(I)FLLL49-GbA was significantly increased toward cancer cells (MCF-7 &gt; A549), while, reduced toward normal cells (HeLa) after loading on chitosan Nano-vehicles.</p>',

			'description' => '<p>BACKGROUND: The cellular response to ionizing radiation involves activation of p53-dependent pathways and activation of the atypical NF-&kappa;B pathway. The crosstalk between these two transcriptional networks include (co)regulation of common gene targets. Here we looked for novel genes potentially (co)regulated by p53 and NF-&kappa;B using integrative genomics screening in human osteosarcoma U2-OS cells irradiated with a high dose (4 and 10&nbsp;Gy). Radiation-induced expression in cells with silenced TP53 or RELA (coding the p65 NF-&kappa;B subunit) genes was analyzed by RNA-Seq while radiation-enhanced binding of p53 and RelA in putative regulatory regions was analyzed by ChIP-Seq, then selected candidates were validated by qPCR. RESULTS: We identified a subset of radiation-modulated genes whose expression was affected by silencing of both TP53 and RELA, and a subset of radiation-upregulated genes where radiation stimulated binding of both p53 and RelA. For three genes, namely IL4I1, SERPINE1, and CDKN1A, an antagonistic effect of the TP53 and RELA silencing was consistent with radiation-enhanced binding of both p53 and RelA. This suggested the possibility of a direct antagonistic (co)regulation by both factors: activation by NF-&kappa;B and inhibition by p53 of IL4I1, and activation by p53 and inhibition by NF-&kappa;B of CDKN1A and SERPINE1. On the other hand, radiation-enhanced binding of both p53 and RelA was observed in a putative regulatory region of the RRAD gene whose expression was downregulated both by TP53 and RELA silencing, which suggested a possibility of direct (co)activation by both factors. CONCLUSIONS: Four new candidates for genes directly co-regulated by NF-&kappa;B and p53 were revealed.</p>',

			'description' => '<p>TREM2 mutations evoke neurodegenerative disorders, and recently genetic variants of this gene were correlated to increased risk of Alzheimer's disease. The signaling cascade originating from the TREM2 membrane receptor includes its binding partner TYROBP, BLNK adapter protein, and SYK kinase, which can be activated by p53. Moreover, in silico identification of a putative p53 response element (RE) at the TREM2 promoter led us to hypothesize that TREM2 and other pathway elements may be regulated in p53-dependent manner. To stimulate p53 in synergistic fashion, we exposed A549 lung cancer cells to actinomycin D and nutlin-3a (A + N). In these cells, exposure to A + N triggered expression of TREM2, TYROBP, SYK and BLNK in p53-dependent manner. TREM2 was also activated by A + N in U-2 OS osteosarcoma and A375 melanoma cell lines. Interestingly, nutlin-3a, a specific activator of p53, acting alone stimulated TREM2 in U-2 OS cells. Using in vitro mutagenesis, chromatin immunoprecipitation, and luciferase reporter assays, we confirmed the presence of the p53 RE in TREM2 promoter. Furthermore, activation of TREM2 and TYROBP by p53 was strongly inhibited by CHIR-98014, a potent and specific inhibitor of glycogen synthase kinase-3 (GSK-3). We conclude that TREM2 is a direct p53-target gene, and that activation of TREM2 by A + N or nutlin-3a may be critically dependent on GSK-3 function.</p>',

	'description' => '<p>TREM2 mutations evoke neurodegenerative disorders, and recently genetic variants of this gene were correlated to increased risk of Alzheimer's disease. The signaling cascade originating from the TREM2 membrane receptor includes its binding partner TYROBP, BLNK adapter protein, and SYK kinase, which can be activated by p53. Moreover, in silico identification of a putative p53 response element (RE) at the TREM2 promoter led us to hypothesize that TREM2 and other pathway elements may be regulated in p53-dependent manner. To stimulate p53 in synergistic fashion, we exposed A549 lung cancer cells to actinomycin D and nutlin-3a (A + N). In these cells, exposure to A + N triggered expression of TREM2, TYROBP, SYK and BLNK in p53-dependent manner. TREM2 was also activated by A + N in U-2 OS osteosarcoma and A375 melanoma cell lines. Interestingly, nutlin-3a, a specific activator of p53, acting alone stimulated TREM2 in U-2 OS cells. Using in vitro mutagenesis, chromatin immunoprecipitation, and luciferase reporter assays, we confirmed the presence of the p53 RE in TREM2 promoter. Furthermore, activation of TREM2 and TYROBP by p53 was strongly inhibited by CHIR-98014, a potent and specific inhibitor of glycogen synthase kinase-3 (GSK-3). We conclude that TREM2 is a direct p53-target gene, and that activation of TREM2 by A + N or nutlin-3a may be critically dependent on GSK-3 function.</p>',

A titration of the antibody consisting of 1, 2, 5, and 10 &micro;g per ChIP experiment was analysed. IgG (2 &micro;g/IP) was used as negative IP control. qPCR was performed with primers for the p21 and GAS6 genes used as positive controls, and for GAPDH promoter and the Sat2 satellite repeat, used as negative controls. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis). </small></p>

<p><br />Chromatin immunoprecipitation (<b>ChIP</b>) is a technique to study the associations of proteins with the specific genomic regions in intact cells. One of the most important steps of this protocol is the immunoprecipitation of targeted protein using the antibody specifically recognizing it. The quality of antibodies used in ChIP is essential for the success of the experiment. Diagenode offers extensively validated ChIP-grade antibodies, confirmed for their specificity, and high level of performance in ChIP.

In addition, chitosan nanoparticles (CNPs) were used to encapsulate this macromolecular complex, targeting enhancing its therapeutic effect and minimizing its side impacts. The encapsulated Ag(I) complex was significantly triggered apoptosis (P &lt; 0.05) with much more rapidly release of Ag(I)FLLL49-GbA from the CNPs at pH 5.3 than at pH 7.4, which is beneficial for cancer-targeted drug delivery. Free complex showed promising ability in preventing glucose uptake and lactate production coupled with cellular ATP depletion in cancer cells. Additionally, there was significant decrease in the inflammatory cytokines in breast cancer (MCF-7) and lung cancer (A549) cells with values of P &lt; 0.01 and P &lt; 0.001 after 24 h incubation. Furthermore, the death-inducing proteins have been significantly up-regulated (P &lt; 0.01 to P &lt; 0.001) after 36 h incubation of cancer cells. Consequently, the novel curcuminoid macromolecule showed significant feasibility in triggering the high expression of apoptotic caspases caspase 3, caspase 8, P53, and Bax (P &lt; 0.01 to P &lt; 0.001) after 48 h of chemotherapy. Noteworthy, the cytotoxicity of Ag(I)FLLL49-GbA was significantly increased toward cancer cells (MCF-7 &gt; A549), while, reduced toward normal cells (HeLa) after loading on chitosan Nano-vehicles.</p>',

			'description' => '<p>BACKGROUND: The cellular response to ionizing radiation involves activation of p53-dependent pathways and activation of the atypical NF-&kappa;B pathway. The crosstalk between these two transcriptional networks include (co)regulation of common gene targets. Here we looked for novel genes potentially (co)regulated by p53 and NF-&kappa;B using integrative genomics screening in human osteosarcoma U2-OS cells irradiated with a high dose (4 and 10&nbsp;Gy). Radiation-induced expression in cells with silenced TP53 or RELA (coding the p65 NF-&kappa;B subunit) genes was analyzed by RNA-Seq while radiation-enhanced binding of p53 and RelA in putative regulatory regions was analyzed by ChIP-Seq, then selected candidates were validated by qPCR. RESULTS: We identified a subset of radiation-modulated genes whose expression was affected by silencing of both TP53 and RELA, and a subset of radiation-upregulated genes where radiation stimulated binding of both p53 and RelA. For three genes, namely IL4I1, SERPINE1, and CDKN1A, an antagonistic effect of the TP53 and RELA silencing was consistent with radiation-enhanced binding of both p53 and RelA. This suggested the possibility of a direct antagonistic (co)regulation by both factors: activation by NF-&kappa;B and inhibition by p53 of IL4I1, and activation by p53 and inhibition by NF-&kappa;B of CDKN1A and SERPINE1. On the other hand, radiation-enhanced binding of both p53 and RelA was observed in a putative regulatory region of the RRAD gene whose expression was downregulated both by TP53 and RELA silencing, which suggested a possibility of direct (co)activation by both factors. CONCLUSIONS: Four new candidates for genes directly co-regulated by NF-&kappa;B and p53 were revealed.</p>',

			'description' => '<p>TREM2 mutations evoke neurodegenerative disorders, and recently genetic variants of this gene were correlated to increased risk of Alzheimer's disease. The signaling cascade originating from the TREM2 membrane receptor includes its binding partner TYROBP, BLNK adapter protein, and SYK kinase, which can be activated by p53. Moreover, in silico identification of a putative p53 response element (RE) at the TREM2 promoter led us to hypothesize that TREM2 and other pathway elements may be regulated in p53-dependent manner. To stimulate p53 in synergistic fashion, we exposed A549 lung cancer cells to actinomycin D and nutlin-3a (A + N). In these cells, exposure to A + N triggered expression of TREM2, TYROBP, SYK and BLNK in p53-dependent manner. TREM2 was also activated by A + N in U-2 OS osteosarcoma and A375 melanoma cell lines. Interestingly, nutlin-3a, a specific activator of p53, acting alone stimulated TREM2 in U-2 OS cells. Using in vitro mutagenesis, chromatin immunoprecipitation, and luciferase reporter assays, we confirmed the presence of the p53 RE in TREM2 promoter. Furthermore, activation of TREM2 and TYROBP by p53 was strongly inhibited by CHIR-98014, a potent and specific inhibitor of glycogen synthase kinase-3 (GSK-3). We conclude that TREM2 is a direct p53-target gene, and that activation of TREM2 by A + N or nutlin-3a may be critically dependent on GSK-3 function.</p>',

	'description' => '<p>TREM2 mutations evoke neurodegenerative disorders, and recently genetic variants of this gene were correlated to increased risk of Alzheimer's disease. The signaling cascade originating from the TREM2 membrane receptor includes its binding partner TYROBP, BLNK adapter protein, and SYK kinase, which can be activated by p53. Moreover, in silico identification of a putative p53 response element (RE) at the TREM2 promoter led us to hypothesize that TREM2 and other pathway elements may be regulated in p53-dependent manner. To stimulate p53 in synergistic fashion, we exposed A549 lung cancer cells to actinomycin D and nutlin-3a (A + N). In these cells, exposure to A + N triggered expression of TREM2, TYROBP, SYK and BLNK in p53-dependent manner. TREM2 was also activated by A + N in U-2 OS osteosarcoma and A375 melanoma cell lines. Interestingly, nutlin-3a, a specific activator of p53, acting alone stimulated TREM2 in U-2 OS cells. Using in vitro mutagenesis, chromatin immunoprecipitation, and luciferase reporter assays, we confirmed the presence of the p53 RE in TREM2 promoter. Furthermore, activation of TREM2 and TYROBP by p53 was strongly inhibited by CHIR-98014, a potent and specific inhibitor of glycogen synthase kinase-3 (GSK-3). We conclude that TREM2 is a direct p53-target gene, and that activation of TREM2 by A + N or nutlin-3a may be critically dependent on GSK-3 function.</p>',

A titration of the antibody consisting of 1, 2, 5, and 10 &micro;g per ChIP experiment was analysed.

<p><br />Chromatin immunoprecipitation (<b>ChIP</b>) is a technique to study the associations of proteins with the specific genomic regions in intact cells. One of the most important steps of this protocol is the immunoprecipitation of targeted protein using the antibody specifically recognizing it. The quality of antibodies used in ChIP is essential for the success of the experiment. Diagenode offers extensively validated ChIP-grade antibodies, confirmed for their specificity, and high level of performance in ChIP.

			'description' => '<p>A novel anticancer and anti-inflammatory agent based on hybrid curcuminoid-Gboxin analog (FLLL49-GbA) and its macromolecular silver(I) complex (Ag(I)FLLL49-GbA) have successfully synthesized. In addition, chitosan nanoparticles (CNPs) were used to encapsulate this macromolecular complex, targeting enhancing its therapeutic effect and minimizing its side impacts. The encapsulated Ag(I) complex was significantly triggered apoptosis (P &lt; 0.05) with much more rapidly release of Ag(I)FLLL49-GbA from the CNPs at pH 5.3 than at pH 7.4, which is beneficial for cancer-targeted drug delivery. Free complex showed promising ability in preventing glucose uptake and lactate production coupled with cellular ATP depletion in cancer cells. Additionally, there was significant decrease in the inflammatory cytokines in breast cancer (MCF-7) and lung cancer (A549) cells with values of P &lt; 0.01 and P &lt; 0.001 after 24 h incubation. Furthermore, the death-inducing proteins have been significantly up-regulated (P &lt; 0.01 to P &lt; 0.001) after 36 h incubation of cancer cells. Consequently, the novel curcuminoid macromolecule showed significant feasibility in triggering the high expression of apoptotic caspases caspase 3, caspase 8, P53, and Bax (P &lt; 0.01 to P &lt; 0.001) after 48 h of chemotherapy. Noteworthy, the cytotoxicity of Ag(I)FLLL49-GbA was significantly increased toward cancer cells (MCF-7 &gt; A549), while, reduced toward normal cells (HeLa) after loading on chitosan Nano-vehicles.</p>',

			'description' => '<p>BACKGROUND: The cellular response to ionizing radiation involves activation of p53-dependent pathways and activation of the atypical NF-&kappa;B pathway. The crosstalk between these two transcriptional networks include (co)regulation of common gene targets. Here we looked for novel genes potentially (co)regulated by p53 and NF-&kappa;B using integrative genomics screening in human osteosarcoma U2-OS cells irradiated with a high dose (4 and 10&nbsp;Gy). Radiation-induced expression in cells with silenced TP53 or RELA (coding the p65 NF-&kappa;B subunit) genes was analyzed by RNA-Seq while radiation-enhanced binding of p53 and RelA in putative regulatory regions was analyzed by ChIP-Seq, then selected candidates were validated by qPCR. RESULTS: We identified a subset of radiation-modulated genes whose expression was affected by silencing of both TP53 and RELA, and a subset of radiation-upregulated genes where radiation stimulated binding of both p53 and RelA. For three genes, namely IL4I1, SERPINE1, and CDKN1A, an antagonistic effect of the TP53 and RELA silencing was consistent with radiation-enhanced binding of both p53 and RelA. This suggested the possibility of a direct antagonistic (co)regulation by both factors: activation by NF-&kappa;B and inhibition by p53 of IL4I1, and activation by p53 and inhibition by NF-&kappa;B of CDKN1A and SERPINE1. On the other hand, radiation-enhanced binding of both p53 and RelA was observed in a putative regulatory region of the RRAD gene whose expression was downregulated both by TP53 and RELA silencing, which suggested a possibility of direct (co)activation by both factors. CONCLUSIONS: Four new candidates for genes directly co-regulated by NF-&kappa;B and p53 were revealed.</p>',

			'description' => '<p>TREM2 mutations evoke neurodegenerative disorders, and recently genetic variants of this gene were correlated to increased risk of Alzheimer's disease. The signaling cascade originating from the TREM2 membrane receptor includes its binding partner TYROBP, BLNK adapter protein, and SYK kinase, which can be activated by p53. Moreover, in silico identification of a putative p53 response element (RE) at the TREM2 promoter led us to hypothesize that TREM2 and other pathway elements may be regulated in p53-dependent manner. To stimulate p53 in synergistic fashion, we exposed A549 lung cancer cells to actinomycin D and nutlin-3a (A + N). In these cells, exposure to A + N triggered expression of TREM2, TYROBP, SYK and BLNK in p53-dependent manner. TREM2 was also activated by A + N in U-2 OS osteosarcoma and A375 melanoma cell lines. Interestingly, nutlin-3a, a specific activator of p53, acting alone stimulated TREM2 in U-2 OS cells. Using in vitro mutagenesis, chromatin immunoprecipitation, and luciferase reporter assays, we confirmed the presence of the p53 RE in TREM2 promoter. Furthermore, activation of TREM2 and TYROBP by p53 was strongly inhibited by CHIR-98014, a potent and specific inhibitor of glycogen synthase kinase-3 (GSK-3). We conclude that TREM2 is a direct p53-target gene, and that activation of TREM2 by A + N or nutlin-3a may be critically dependent on GSK-3 function.</p>',

	'description' => '<p>TREM2 mutations evoke neurodegenerative disorders, and recently genetic variants of this gene were correlated to increased risk of Alzheimer's disease. The signaling cascade originating from the TREM2 membrane receptor includes its binding partner TYROBP, BLNK adapter protein, and SYK kinase, which can be activated by p53. Moreover, in silico identification of a putative p53 response element (RE) at the TREM2 promoter led us to hypothesize that TREM2 and other pathway elements may be regulated in p53-dependent manner. To stimulate p53 in synergistic fashion, we exposed A549 lung cancer cells to actinomycin D and nutlin-3a (A + N). In these cells, exposure to A + N triggered expression of TREM2, TYROBP, SYK and BLNK in p53-dependent manner. TREM2 was also activated by A + N in U-2 OS osteosarcoma and A375 melanoma cell lines. Interestingly, nutlin-3a, a specific activator of p53, acting alone stimulated TREM2 in U-2 OS cells. Using in vitro mutagenesis, chromatin immunoprecipitation, and luciferase reporter assays, we confirmed the presence of the p53 RE in TREM2 promoter. Furthermore, activation of TREM2 and TYROBP by p53 was strongly inhibited by CHIR-98014, a potent and specific inhibitor of glycogen synthase kinase-3 (GSK-3). We conclude that TREM2 is a direct p53-target gene, and that activation of TREM2 by A + N or nutlin-3a may be critically dependent on GSK-3 function.</p>',

ChIP results obtained with the Diagenode antibody directed against p53</strong><br /> ChIP assays were performed using human U2OS cells, treated with camptothecin, the Diagenode antibody against p53 (Cat.

A titration of the antibody consisting of 1, 2, 5, and 10 &micro;g per ChIP experiment was analysed. IgG (2 &micro;g/IP) was used as negative IP control. qPCR was performed with primers for the p21 and GAS6 genes used as positive controls, and for GAPDH promoter and the Sat2 satellite repeat, used as negative controls.

<p><br />Chromatin immunoprecipitation (<b>ChIP</b>) is a technique to study the associations of proteins with the specific genomic regions in intact cells. One of the most important steps of this protocol is the immunoprecipitation of targeted protein using the antibody specifically recognizing it. The quality of antibodies used in ChIP is essential for the success of the experiment. Diagenode offers extensively validated ChIP-grade antibodies, confirmed for their specificity, and high level of performance in ChIP. Each batch is validated, and batch-specific data are available on the website.</p>

In addition, chitosan nanoparticles (CNPs) were used to encapsulate this macromolecular complex, targeting enhancing its therapeutic effect and minimizing its side impacts. The encapsulated Ag(I) complex was significantly triggered apoptosis (P &lt; 0.05) with much more rapidly release of Ag(I)FLLL49-GbA from the CNPs at pH 5.3 than at pH 7.4, which is beneficial for cancer-targeted drug delivery. Free complex showed promising ability in preventing glucose uptake and lactate production coupled with cellular ATP depletion in cancer cells. Additionally, there was significant decrease in the inflammatory cytokines in breast cancer (MCF-7) and lung cancer (A549) cells with values of P &lt; 0.01 and P &lt; 0.001 after 24 h incubation. Furthermore, the death-inducing proteins have been significantly up-regulated (P &lt; 0.01 to P &lt; 0.001) after 36 h incubation of cancer cells. Consequently, the novel curcuminoid macromolecule showed significant feasibility in triggering the high expression of apoptotic caspases caspase 3, caspase 8, P53, and Bax (P &lt; 0.01 to P &lt; 0.001) after 48 h of chemotherapy. Noteworthy, the cytotoxicity of Ag(I)FLLL49-GbA was significantly increased toward cancer cells (MCF-7 &gt; A549), while, reduced toward normal cells (HeLa) after loading on chitosan Nano-vehicles.</p>',

			'description' => '<p>BACKGROUND: The cellular response to ionizing radiation involves activation of p53-dependent pathways and activation of the atypical NF-&kappa;B pathway. The crosstalk between these two transcriptional networks include (co)regulation of common gene targets. Here we looked for novel genes potentially (co)regulated by p53 and NF-&kappa;B using integrative genomics screening in human osteosarcoma U2-OS cells irradiated with a high dose (4 and 10&nbsp;Gy). Radiation-induced expression in cells with silenced TP53 or RELA (coding the p65 NF-&kappa;B subunit) genes was analyzed by RNA-Seq while radiation-enhanced binding of p53 and RelA in putative regulatory regions was analyzed by ChIP-Seq, then selected candidates were validated by qPCR. RESULTS: We identified a subset of radiation-modulated genes whose expression was affected by silencing of both TP53 and RELA, and a subset of radiation-upregulated genes where radiation stimulated binding of both p53 and RelA. For three genes, namely IL4I1, SERPINE1, and CDKN1A, an antagonistic effect of the TP53 and RELA silencing was consistent with radiation-enhanced binding of both p53 and RelA. This suggested the possibility of a direct antagonistic (co)regulation by both factors: activation by NF-&kappa;B and inhibition by p53 of IL4I1, and activation by p53 and inhibition by NF-&kappa;B of CDKN1A and SERPINE1. On the other hand, radiation-enhanced binding of both p53 and RelA was observed in a putative regulatory region of the RRAD gene whose expression was downregulated both by TP53 and RELA silencing, which suggested a possibility of direct (co)activation by both factors. CONCLUSIONS: Four new candidates for genes directly co-regulated by NF-&kappa;B and p53 were revealed.</p>',

			'description' => '<p>TREM2 mutations evoke neurodegenerative disorders, and recently genetic variants of this gene were correlated to increased risk of Alzheimer's disease. The signaling cascade originating from the TREM2 membrane receptor includes its binding partner TYROBP, BLNK adapter protein, and SYK kinase, which can be activated by p53. Moreover, in silico identification of a putative p53 response element (RE) at the TREM2 promoter led us to hypothesize that TREM2 and other pathway elements may be regulated in p53-dependent manner. To stimulate p53 in synergistic fashion, we exposed A549 lung cancer cells to actinomycin D and nutlin-3a (A + N). In these cells, exposure to A + N triggered expression of TREM2, TYROBP, SYK and BLNK in p53-dependent manner. TREM2 was also activated by A + N in U-2 OS osteosarcoma and A375 melanoma cell lines. Interestingly, nutlin-3a, a specific activator of p53, acting alone stimulated TREM2 in U-2 OS cells. Using in vitro mutagenesis, chromatin immunoprecipitation, and luciferase reporter assays, we confirmed the presence of the p53 RE in TREM2 promoter. Furthermore, activation of TREM2 and TYROBP by p53 was strongly inhibited by CHIR-98014, a potent and specific inhibitor of glycogen synthase kinase-3 (GSK-3). We conclude that TREM2 is a direct p53-target gene, and that activation of TREM2 by A + N or nutlin-3a may be critically dependent on GSK-3 function.</p>',

ChIP results obtained with the Diagenode antibody directed against p53</strong><br /> ChIP assays were performed using human U2OS cells, treated with camptothecin, the Diagenode antibody against p53 (Cat. No. C15410083) and optimized PCR primer sets for qPCR. ChIP was performed on sheared chromatin from 4 million cells. A titration of the antibody consisting of 1, 2, 5, and 10 &micro;g per ChIP experiment was analysed. IgG (2 &micro;g/IP) was used as negative IP control. qPCR was performed with primers for the p21 and GAS6 genes used as positive controls, and for GAPDH promoter and the Sat2 satellite repeat, used as negative controls. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis). </small></p>

Upon activation, p53 induces several target genes which leads to cell cycle arrest and DNA repair, or alternatively, to apoptosis. In unstressed cells, p53 is kept inactive by the ubiquitin ligase MDM2 which inhibits the activity and promotes the degradation. Mutations in p53 are involved in a vast majority of human cancers.</p>',

	'description' => '<p>TREM2 mutations evoke neurodegenerative disorders, and recently genetic variants of this gene were correlated to increased risk of Alzheimer's disease. The signaling cascade originating from the TREM2 membrane receptor includes its binding partner TYROBP, BLNK adapter protein, and SYK kinase, which can be activated by p53. Moreover, in silico identification of a putative p53 response element (RE) at the TREM2 promoter led us to hypothesize that TREM2 and other pathway elements may be regulated in p53-dependent manner. To stimulate p53 in synergistic fashion, we exposed A549 lung cancer cells to actinomycin D and nutlin-3a (A + N). In these cells, exposure to A + N triggered expression of TREM2, TYROBP, SYK and BLNK in p53-dependent manner. TREM2 was also activated by A + N in U-2 OS osteosarcoma and A375 melanoma cell lines. Interestingly, nutlin-3a, a specific activator of p53, acting alone stimulated TREM2 in U-2 OS cells. Using in vitro mutagenesis, chromatin immunoprecipitation, and luciferase reporter assays, we confirmed the presence of the p53 RE in TREM2 promoter. Furthermore, activation of TREM2 and TYROBP by p53 was strongly inhibited by CHIR-98014, a potent and specific inhibitor of glycogen synthase kinase-3 (GSK-3). We conclude that TREM2 is a direct p53-target gene, and that activation of TREM2 by A + N or nutlin-3a may be critically dependent on GSK-3 function.</p>',
