Figure 1. ChIP using the Diagenode monoclonal antibody against hERα
from ChIP assays were performed using MCF7 cells, treated with the ER agonist estradiol for 3 hours prior to harvesting., the Diagenode monoclonal antibody directed against ER alpha (Cat. No. MAb-009-050) and optimized primer sets for qPCR. Sheared chromatin from 3 million cells and 5 µg of antibody were used per ChIP experiment. Recovery (%: ChIP/input) and occupancy (x fold: +ve/-ve) are shown in figure 1. QPCR was performed with primers for the GREB1 promoter and for exon 2 of the myoglobin gene (Cat. No. pp-1006-050), used as a negative control. Figure 1 shows the recovery (the relative amount of immunoprecipitated DNA compared to input DNA) and the occupancy (ratio +/- control target). These results demonstrate the occupancy of the GREB1 promoter by ERalpha.
Figure 2. Western blot analysis using the Diagenode monoclonal antibody against hERα
Western blot analysis was performed on 100 fmol ER alpha (ERa) and ER beta (ERb1) recombinant protein with the Diagenode monoclonal antibody directed against ER alpha (Cat. No. MAb-009-050) at a concentration of 7 µg/ml. Figure 2 shows the specificity of the antibody for the ER alpha isoform, whereas the ER beta isoform is not recognized.
Figure 3. Immunocytochemistry using the Diagenode monoclonal antibody against hERα
COS-7 cells transiently overexpressing human ERα (left) or ERß1 (right) were labeled with the Diagenode antibody against ER alpha (Cat. No. MAb-009-050), used at a concentration of 15 µg/ml, followed by a biotinylated secondary antibody and peroxidase-labeled avidin. Figure 3 shows the specificity of the antibody for the ER alpha isoform.

We report that ERα ligand oestradiol (E2) is significantly increased in human cervical cancer (CxCa) tissues and tumour-infiltrating T<sub>reg</sub> cells (CD4<sup>+</sup>CD25<sup>hi</sup>CD127<sup>low</sup>), whereas blocking ERα with the antagonist ICI 182,780 abolishes FOXP3 expression and impairs the function of CxCa infiltrating T<sub>reg</sub> cells. Using a novel approach of co-immunoprecipitation with antibodies to E2 for capture, we identified binding of E2:ERα complexes to FOXP3 protein in CxCa-derived T<sub>reg</sub> cells. Chromatin immunoprecipitation analyses of male blood T<sub>reg</sub> cells revealed ERα occupancy at the FOXP3 promoter and conserved non-coding DNA elements 2 and 3. Accordingly, computational analyses of the enriched regions uncovered eight putative oestrogen response elements predicted to form a loop that can activate the FOXP3 promoter. Together, these data suggest that E2-mediated ERα signalling is critical for the sustenance of FOXP3 expression and T<sub>reg</sub> cell function in human CxCa via direct interaction of ERα with FOXP3 promoter. Overall, our work gives a molecular insight into ERα signalling and highlights a fundamental role of E2 in controlling human T<sub>reg</sub> cell physiology.</p>', 'date' => '2017-12-11', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/29229929', 'doi' => '', 'modified' => '2018-04-24 10:07:53', 'created' => '2018-04-24 10:07:53', 'ProductsPublication' => array( [maximum depth reached] ) ) ), 'Testimonial' => array(), 'Area' => array(), 'SafetySheet' => array( (int) 0 => array( 'id' => '574', 'name' => 'ER alpha antibody SDS GB en', 'language' => 'en', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-GB-en-GHS_2_0.pdf', 'countries' => 'GB', 'modified' => '2020-07-01 14:58:20', 'created' => '2020-07-01 14:58:20', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 1 => array( 'id' => '576', 'name' => 'ER alpha antibody SDS US en', 'language' => 'en', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-US-en-GHS_2_0.pdf', 'countries' => 'US', 'modified' => '2020-07-01 14:59:24', 'created' => '2020-07-01 14:59:24', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 2 => array( 'id' => '571', 'name' => 'ER alpha antibody SDS DE de', 'language' => 'de', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-DE-de-GHS_2_0.pdf', 'countries' => 'DE', 'modified' => '2020-07-01 14:56:44', 'created' => '2020-07-01 14:56:44', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 3 => array( 'id' => '575', 'name' => 'ER alpha antibody SDS JP ja', 'language' => 'ja', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-JP-ja-GHS_2_0.pdf', 'countries' => 'JP', 'modified' => '2020-07-01 14:58:55', 'created' => '2020-07-01 14:58:55', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 4 => array( 'id' => '570', 'name' => 'ER alpha antibody SDS BE nl', 'language' => 'nl', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-BE-nl-GHS_2_0.pdf', 'countries' => 'BE', 'modified' => '2020-07-01 14:56:20', 'created' => '2020-07-01 14:56:20', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 5 => array( 'id' => '569', 'name' => 'ER alpha antibody SDS BE fr', 'language' => 'fr', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-BE-fr-GHS_2_0.pdf', 'countries' => 'BE', 'modified' => '2020-07-01 14:55:44', 'created' => '2020-07-01 14:55:44', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 6 => array( 'id' => '573', 'name' => 'ER alpha antibody SDS FR fr', 'language' => 'fr', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-FR-fr-GHS_2_0.pdf', 'countries' => 'FR', 'modified' => '2020-07-01 14:57:51', 'created' => '2020-07-01 14:57:51', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 7 => array( 'id' => '572', 'name' => 'ER alpha antibody SDS ES es', 'language' => 'es', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-ES-es-GHS_2_0.pdf', 'countries' => 'ES', 'modified' => '2020-07-01 14:57:14', 'created' => '2020-07-01 14:57:14', 'ProductsSafetySheet' => array( [maximum depth reached] ) ) ) ) $meta_canonical = 'https://www.diagenode.com/en/p/er-alpha-monoclonal-antibody-classic-50-ug-25-ul' $country = 'US' $countries_allowed = array( (int) 0 => 'CA', (int) 1 => 'US', (int) 2 => 'IE', (int) 3 => 'GB', (int) 4 => 'DK', (int) 5 => 'NO', (int) 6 => 'SE', (int) 7 => 'FI', (int) 8 => 'NL', (int) 9 => 'BE', (int) 10 => 'LU', (int) 11 => 'FR', (int) 12 => 'DE', (int) 13 => 'CH', (int) 14 => 'AT', (int) 15 => 'ES', (int) 16 => 'IT', (int) 17 => 'PT' ) $outsource = true $other_formats = array( (int) 0 => array( 'id' => '1968', 'antibody_id' => '103', 'name' => 'ER alpha Antibody', 'description' => '<p>Alternative names:<strong>ESR</strong>, <strong>ESR1</strong>, <strong>ESRA</strong>, <strong>NR3A1</strong></p> <p><span>Monoclonal antibody raised in mouse against the NH2 terminus of the human <strong>ERα</strong> (estrogen receptor alpha), using a KLH-conjugated synthetic peptide (Q19-K32).</span></p>', 'label1' => 'Validation Data', 'info1' => '<div class="row"> <div class="small-4 columns"> <p><img src="https://www.diagenode.com/img/product/antibodies/C15200009_fig1.png" alt="ER alpha Antibody ChIP Grade" style="display: block; margin-left: auto; margin-right: auto;" /></p> </div> <div class="small-8 columns"> <p><small><strong> Figure 1.

We report that ERα ligand oestradiol (E2) is significantly increased in human cervical cancer (CxCa) tissues and tumour-infiltrating T<sub>reg</sub> cells (CD4<sup>+</sup>CD25<sup>hi</sup>CD127<sup>low</sup>), whereas blocking ERα with the antagonist ICI 182,780 abolishes FOXP3 expression and impairs the function of CxCa infiltrating T<sub>reg</sub> cells. Using a novel approach of co-immunoprecipitation with antibodies to E2 for capture, we identified binding of E2:ERα complexes to FOXP3 protein in CxCa-derived T<sub>reg</sub> cells. Chromatin immunoprecipitation analyses of male blood T<sub>reg</sub> cells revealed ERα occupancy at the FOXP3 promoter and conserved non-coding DNA elements 2 and 3. Accordingly, computational analyses of the enriched regions uncovered eight putative oestrogen response elements predicted to form a loop that can activate the FOXP3 promoter. Together, these data suggest that E2-mediated ERα signalling is critical for the sustenance of FOXP3 expression and T<sub>reg</sub> cell function in human CxCa via direct interaction of ERα with FOXP3 promoter. Overall, our work gives a molecular insight into ERα signalling and highlights a fundamental role of E2 in controlling human T<sub>reg</sub> cell physiology.</p>', 'date' => '2017-12-11', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/29229929', 'doi' => '', 'modified' => '2018-04-24 10:07:53', 'created' => '2018-04-24 10:07:53', 'ProductsPublication' => array( 'id' => '2735', 'product_id' => '1969', 'publication_id' => '3363' ) ) $externalLink = ' <a href="https://www.ncbi.nlm.nih.gov/pubmed/29229929" target="_blank"><i class="fa fa-external-link"></i></a>'include - APP/View/Products/view.ctp, line 755 View::_evaluate() - CORE/Cake/View/View.php, line 971 View::_render() - CORE/Cake/View/View.php, line 933 View::render() - CORE/Cake/View/View.php, line 473 Controller::render() - CORE/Cake/Controller/Controller.php, line 963 ProductsController::slug() - APP/Controller/ProductsController.php, line 1052 ReflectionMethod::invokeArgs() - [internal], line ??

We report that ERα ligand oestradiol (E2) is significantly increased in human cervical cancer (CxCa) tissues and tumour-infiltrating T<sub>reg</sub> cells (CD4<sup>+</sup>CD25<sup>hi</sup>CD127<sup>low</sup>), whereas blocking ERα with the antagonist ICI 182,780 abolishes FOXP3 expression and impairs the function of CxCa infiltrating T<sub>reg</sub> cells. Using a novel approach of co-immunoprecipitation with antibodies to E2 for capture, we identified binding of E2:ERα complexes to FOXP3 protein in CxCa-derived T<sub>reg</sub> cells. Chromatin immunoprecipitation analyses of male blood T<sub>reg</sub> cells revealed ERα occupancy at the FOXP3 promoter and conserved non-coding DNA elements 2 and 3. Accordingly, computational analyses of the enriched regions uncovered eight putative oestrogen response elements predicted to form a loop that can activate the FOXP3 promoter. Together, these data suggest that E2-mediated ERα signalling is critical for the sustenance of FOXP3 expression and T<sub>reg</sub> cell function in human CxCa via direct interaction of ERα with FOXP3 promoter. Overall, our work gives a molecular insight into ERα signalling and highlights a fundamental role of E2 in controlling human T<sub>reg</sub> cell physiology.</p>', 'date' => '2017-12-11', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/29229929', 'doi' => '', 'modified' => '2018-04-24 10:07:53', 'created' => '2018-04-24 10:07:53', 'ProductsPublication' => array( [maximum depth reached] ) ) ), 'Testimonial' => array(), 'Area' => array(), 'SafetySheet' => array( (int) 0 => array( 'id' => '574', 'name' => 'ER alpha antibody SDS GB en', 'language' => 'en', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-GB-en-GHS_2_0.pdf', 'countries' => 'GB', 'modified' => '2020-07-01 14:58:20', 'created' => '2020-07-01 14:58:20', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 1 => array( 'id' => '576', 'name' => 'ER alpha antibody SDS US en', 'language' => 'en', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-US-en-GHS_2_0.pdf', 'countries' => 'US', 'modified' => '2020-07-01 14:59:24', 'created' => '2020-07-01 14:59:24', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 2 => array( 'id' => '571', 'name' => 'ER alpha antibody SDS DE de', 'language' => 'de', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-DE-de-GHS_2_0.pdf', 'countries' => 'DE', 'modified' => '2020-07-01 14:56:44', 'created' => '2020-07-01 14:56:44', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 3 => array( 'id' => '575', 'name' => 'ER alpha antibody SDS JP ja', 'language' => 'ja', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-JP-ja-GHS_2_0.pdf', 'countries' => 'JP', 'modified' => '2020-07-01 14:58:55', 'created' => '2020-07-01 14:58:55', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 4 => array( 'id' => '570', 'name' => 'ER alpha antibody SDS BE nl', 'language' => 'nl', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-BE-nl-GHS_2_0.pdf', 'countries' => 'BE', 'modified' => '2020-07-01 14:56:20', 'created' => '2020-07-01 14:56:20', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 5 => array( 'id' => '569', 'name' => 'ER alpha antibody SDS BE fr', 'language' => 'fr', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-BE-fr-GHS_2_0.pdf', 'countries' => 'BE', 'modified' => '2020-07-01 14:55:44', 'created' => '2020-07-01 14:55:44', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 6 => array( 'id' => '573', 'name' => 'ER alpha antibody SDS FR fr', 'language' => 'fr', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-FR-fr-GHS_2_0.pdf', 'countries' => 'FR', 'modified' => '2020-07-01 14:57:51', 'created' => '2020-07-01 14:57:51', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 7 => array( 'id' => '572', 'name' => 'ER alpha antibody SDS ES es', 'language' => 'es', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-ES-es-GHS_2_0.pdf', 'countries' => 'ES', 'modified' => '2020-07-01 14:57:14', 'created' => '2020-07-01 14:57:14', 'ProductsSafetySheet' => array( [maximum depth reached] ) ) ) ) $meta_canonical = 'https://www.diagenode.com/en/p/er-alpha-monoclonal-antibody-classic-50-ug-25-ul' $country = 'US' $countries_allowed = array( (int) 0 => 'CA', (int) 1 => 'US', (int) 2 => 'IE', (int) 3 => 'GB', (int) 4 => 'DK', (int) 5 => 'NO', (int) 6 => 'SE', (int) 7 => 'FI', (int) 8 => 'NL', (int) 9 => 'BE', (int) 10 => 'LU', (int) 11 => 'FR', (int) 12 => 'DE', (int) 13 => 'CH', (int) 14 => 'AT', (int) 15 => 'ES', (int) 16 => 'IT', (int) 17 => 'PT' ) $outsource = true $other_formats = array( (int) 0 => array( 'id' => '1968', 'antibody_id' => '103', 'name' => 'ER alpha Antibody', 'description' => '<p>Alternative names:<strong>ESR</strong>, <strong>ESR1</strong>, <strong>ESRA</strong>, <strong>NR3A1</strong></p> <p><span>Monoclonal antibody raised in mouse against the NH2 terminus of the human <strong>ERα</strong> (estrogen receptor alpha), using a KLH-conjugated synthetic peptide (Q19-K32).</span></p>', 'label1' => 'Validation Data', 'info1' => '<div class="row"> <div class="small-4 columns"> <p><img src="https://www.diagenode.com/img/product/antibodies/C15200009_fig1.png" alt="ER alpha Antibody ChIP Grade" style="display: block; margin-left: auto; margin-right: auto;" /></p> </div> <div class="small-8 columns"> <p><small><strong> Figure 1.

We report that ERα ligand oestradiol (E2) is significantly increased in human cervical cancer (CxCa) tissues and tumour-infiltrating T<sub>reg</sub> cells (CD4<sup>+</sup>CD25<sup>hi</sup>CD127<sup>low</sup>), whereas blocking ERα with the antagonist ICI 182,780 abolishes FOXP3 expression and impairs the function of CxCa infiltrating T<sub>reg</sub> cells. Using a novel approach of co-immunoprecipitation with antibodies to E2 for capture, we identified binding of E2:ERα complexes to FOXP3 protein in CxCa-derived T<sub>reg</sub> cells. Chromatin immunoprecipitation analyses of male blood T<sub>reg</sub> cells revealed ERα occupancy at the FOXP3 promoter and conserved non-coding DNA elements 2 and 3. Accordingly, computational analyses of the enriched regions uncovered eight putative oestrogen response elements predicted to form a loop that can activate the FOXP3 promoter. Together, these data suggest that E2-mediated ERα signalling is critical for the sustenance of FOXP3 expression and T<sub>reg</sub> cell function in human CxCa via direct interaction of ERα with FOXP3 promoter. Overall, our work gives a molecular insight into ERα signalling and highlights a fundamental role of E2 in controlling human T<sub>reg</sub> cell physiology.</p>', 'date' => '2017-12-11', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/29229929', 'doi' => '', 'modified' => '2018-04-24 10:07:53', 'created' => '2018-04-24 10:07:53', 'ProductsPublication' => array( 'id' => '2735', 'product_id' => '1969', 'publication_id' => '3363' ) ) $externalLink = ' <a href="https://www.ncbi.nlm.nih.gov/pubmed/29229929" target="_blank"><i class="fa fa-external-link"></i></a>'include - APP/View/Products/view.ctp, line 755 View::_evaluate() - CORE/Cake/View/View.php, line 971 View::_render() - CORE/Cake/View/View.php, line 933 View::render() - CORE/Cake/View/View.php, line 473 Controller::render() - CORE/Cake/Controller/Controller.php, line 963 ProductsController::slug() - APP/Controller/ProductsController.php, line 1052 ReflectionMethod::invokeArgs() - [internal], line ??

We report that ERα ligand oestradiol (E2) is significantly increased in human cervical cancer (CxCa) tissues and tumour-infiltrating T<sub>reg</sub> cells (CD4<sup>+</sup>CD25<sup>hi</sup>CD127<sup>low</sup>), whereas blocking ERα with the antagonist ICI 182,780 abolishes FOXP3 expression and impairs the function of CxCa infiltrating T<sub>reg</sub> cells. Using a novel approach of co-immunoprecipitation with antibodies to E2 for capture, we identified binding of E2:ERα complexes to FOXP3 protein in CxCa-derived T<sub>reg</sub> cells. Chromatin immunoprecipitation analyses of male blood T<sub>reg</sub> cells revealed ERα occupancy at the FOXP3 promoter and conserved non-coding DNA elements 2 and 3. Accordingly, computational analyses of the enriched regions uncovered eight putative oestrogen response elements predicted to form a loop that can activate the FOXP3 promoter. Together, these data suggest that E2-mediated ERα signalling is critical for the sustenance of FOXP3 expression and T<sub>reg</sub> cell function in human CxCa via direct interaction of ERα with FOXP3 promoter. Overall, our work gives a molecular insight into ERα signalling and highlights a fundamental role of E2 in controlling human T<sub>reg</sub> cell physiology.</p>', 'date' => '2017-12-11', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/29229929', 'doi' => '', 'modified' => '2018-04-24 10:07:53', 'created' => '2018-04-24 10:07:53', 'ProductsPublication' => array( [maximum depth reached] ) ) ), 'Testimonial' => array(), 'Area' => array(), 'SafetySheet' => array( (int) 0 => array( 'id' => '574', 'name' => 'ER alpha antibody SDS GB en', 'language' => 'en', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-GB-en-GHS_2_0.pdf', 'countries' => 'GB', 'modified' => '2020-07-01 14:58:20', 'created' => '2020-07-01 14:58:20', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 1 => array( 'id' => '576', 'name' => 'ER alpha antibody SDS US en', 'language' => 'en', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-US-en-GHS_2_0.pdf', 'countries' => 'US', 'modified' => '2020-07-01 14:59:24', 'created' => '2020-07-01 14:59:24', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 2 => array( 'id' => '571', 'name' => 'ER alpha antibody SDS DE de', 'language' => 'de', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-DE-de-GHS_2_0.pdf', 'countries' => 'DE', 'modified' => '2020-07-01 14:56:44', 'created' => '2020-07-01 14:56:44', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 3 => array( 'id' => '575', 'name' => 'ER alpha antibody SDS JP ja', 'language' => 'ja', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-JP-ja-GHS_2_0.pdf', 'countries' => 'JP', 'modified' => '2020-07-01 14:58:55', 'created' => '2020-07-01 14:58:55', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 4 => array( 'id' => '570', 'name' => 'ER alpha antibody SDS BE nl', 'language' => 'nl', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-BE-nl-GHS_2_0.pdf', 'countries' => 'BE', 'modified' => '2020-07-01 14:56:20', 'created' => '2020-07-01 14:56:20', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 5 => array( 'id' => '569', 'name' => 'ER alpha antibody SDS BE fr', 'language' => 'fr', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-BE-fr-GHS_2_0.pdf', 'countries' => 'BE', 'modified' => '2020-07-01 14:55:44', 'created' => '2020-07-01 14:55:44', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 6 => array( 'id' => '573', 'name' => 'ER alpha antibody SDS FR fr', 'language' => 'fr', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-FR-fr-GHS_2_0.pdf', 'countries' => 'FR', 'modified' => '2020-07-01 14:57:51', 'created' => '2020-07-01 14:57:51', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 7 => array( 'id' => '572', 'name' => 'ER alpha antibody SDS ES es', 'language' => 'es', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-ES-es-GHS_2_0.pdf', 'countries' => 'ES', 'modified' => '2020-07-01 14:57:14', 'created' => '2020-07-01 14:57:14', 'ProductsSafetySheet' => array( [maximum depth reached] ) ) ) ) $meta_canonical = 'https://www.diagenode.com/en/p/er-alpha-monoclonal-antibody-classic-50-ug-25-ul' $country = 'US' $countries_allowed = array( (int) 0 => 'CA', (int) 1 => 'US', (int) 2 => 'IE', (int) 3 => 'GB', (int) 4 => 'DK', (int) 5 => 'NO', (int) 6 => 'SE', (int) 7 => 'FI', (int) 8 => 'NL', (int) 9 => 'BE', (int) 10 => 'LU', (int) 11 => 'FR', (int) 12 => 'DE', (int) 13 => 'CH', (int) 14 => 'AT', (int) 15 => 'ES', (int) 16 => 'IT', (int) 17 => 'PT' ) $outsource = true $other_formats = array( (int) 0 => array( 'id' => '1968', 'antibody_id' => '103', 'name' => 'ER alpha Antibody', 'description' => '<p>Alternative names:<strong>ESR</strong>, <strong>ESR1</strong>, <strong>ESRA</strong>, <strong>NR3A1</strong></p> <p><span>Monoclonal antibody raised in mouse against the NH2 terminus of the human <strong>ERα</strong> (estrogen receptor alpha), using a KLH-conjugated synthetic peptide (Q19-K32).</span></p>', 'label1' => 'Validation Data', 'info1' => '<div class="row"> <div class="small-4 columns"> <p><img src="https://www.diagenode.com/img/product/antibodies/C15200009_fig1.png" alt="ER alpha Antibody ChIP Grade" style="display: block; margin-left: auto; margin-right: auto;" /></p> </div> <div class="small-8 columns"> <p><small><strong> Figure 1.

We report that ERα ligand oestradiol (E2) is significantly increased in human cervical cancer (CxCa) tissues and tumour-infiltrating T<sub>reg</sub> cells (CD4<sup>+</sup>CD25<sup>hi</sup>CD127<sup>low</sup>), whereas blocking ERα with the antagonist ICI 182,780 abolishes FOXP3 expression and impairs the function of CxCa infiltrating T<sub>reg</sub> cells. Using a novel approach of co-immunoprecipitation with antibodies to E2 for capture, we identified binding of E2:ERα complexes to FOXP3 protein in CxCa-derived T<sub>reg</sub> cells. Chromatin immunoprecipitation analyses of male blood T<sub>reg</sub> cells revealed ERα occupancy at the FOXP3 promoter and conserved non-coding DNA elements 2 and 3. Accordingly, computational analyses of the enriched regions uncovered eight putative oestrogen response elements predicted to form a loop that can activate the FOXP3 promoter. Together, these data suggest that E2-mediated ERα signalling is critical for the sustenance of FOXP3 expression and T<sub>reg</sub> cell function in human CxCa via direct interaction of ERα with FOXP3 promoter.

We report that ERα ligand oestradiol (E2) is significantly increased in human cervical cancer (CxCa) tissues and tumour-infiltrating T<sub>reg</sub> cells (CD4<sup>+</sup>CD25<sup>hi</sup>CD127<sup>low</sup>), whereas blocking ERα with the antagonist ICI 182,780 abolishes FOXP3 expression and impairs the function of CxCa infiltrating T<sub>reg</sub> cells. Using a novel approach of co-immunoprecipitation with antibodies to E2 for capture, we identified binding of E2:ERα complexes to FOXP3 protein in CxCa-derived T<sub>reg</sub> cells. Chromatin immunoprecipitation analyses of male blood T<sub>reg</sub> cells revealed ERα occupancy at the FOXP3 promoter and conserved non-coding DNA elements 2 and 3. Accordingly, computational analyses of the enriched regions uncovered eight putative oestrogen response elements predicted to form a loop that can activate the FOXP3 promoter. Together, these data suggest that E2-mediated ERα signalling is critical for the sustenance of FOXP3 expression and T<sub>reg</sub> cell function in human CxCa via direct interaction of ERα with FOXP3 promoter. Overall, our work gives a molecular insight into ERα signalling and highlights a fundamental role of E2 in controlling human T<sub>reg</sub> cell physiology.</p>', 'date' => '2017-12-11', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/29229929', 'doi' => '', 'modified' => '2018-04-24 10:07:53', 'created' => '2018-04-24 10:07:53', 'ProductsPublication' => array( [maximum depth reached] ) ) ), 'Testimonial' => array(), 'Area' => array(), 'SafetySheet' => array( (int) 0 => array( 'id' => '574', 'name' => 'ER alpha antibody SDS GB en', 'language' => 'en', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-GB-en-GHS_2_0.pdf', 'countries' => 'GB', 'modified' => '2020-07-01 14:58:20', 'created' => '2020-07-01 14:58:20', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 1 => array( 'id' => '576', 'name' => 'ER alpha antibody SDS US en', 'language' => 'en', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-US-en-GHS_2_0.pdf', 'countries' => 'US', 'modified' => '2020-07-01 14:59:24', 'created' => '2020-07-01 14:59:24', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 2 => array( 'id' => '571', 'name' => 'ER alpha antibody SDS DE de', 'language' => 'de', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-DE-de-GHS_2_0.pdf', 'countries' => 'DE', 'modified' => '2020-07-01 14:56:44', 'created' => '2020-07-01 14:56:44', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 3 => array( 'id' => '575', 'name' => 'ER alpha antibody SDS JP ja', 'language' => 'ja', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-JP-ja-GHS_2_0.pdf', 'countries' => 'JP', 'modified' => '2020-07-01 14:58:55', 'created' => '2020-07-01 14:58:55', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 4 => array( 'id' => '570', 'name' => 'ER alpha antibody SDS BE nl', 'language' => 'nl', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-BE-nl-GHS_2_0.pdf', 'countries' => 'BE', 'modified' => '2020-07-01 14:56:20', 'created' => '2020-07-01 14:56:20', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 5 => array( 'id' => '569', 'name' => 'ER alpha antibody SDS BE fr', 'language' => 'fr', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-BE-fr-GHS_2_0.pdf', 'countries' => 'BE', 'modified' => '2020-07-01 14:55:44', 'created' => '2020-07-01 14:55:44', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 6 => array( 'id' => '573', 'name' => 'ER alpha antibody SDS FR fr', 'language' => 'fr', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-FR-fr-GHS_2_0.pdf', 'countries' => 'FR', 'modified' => '2020-07-01 14:57:51', 'created' => '2020-07-01 14:57:51', 'ProductsSafetySheet' => array( [maximum depth reached] ) ), (int) 7 => array( 'id' => '572', 'name' => 'ER alpha antibody SDS ES es', 'language' => 'es', 'url' => 'files/SDS/ER/SDS-C15200009-ER_alpha_Antibody-ES-es-GHS_2_0.pdf', 'countries' => 'ES', 'modified' => '2020-07-01 14:57:14', 'created' => '2020-07-01 14:57:14', 'ProductsSafetySheet' => array( [maximum depth reached] ) ) ) ) $meta_canonical = 'https://www.diagenode.com/en/p/er-alpha-monoclonal-antibody-classic-50-ug-25-ul' $country = 'US' $countries_allowed = array( (int) 0 => 'CA', (int) 1 => 'US', (int) 2 => 'IE', (int) 3 => 'GB', (int) 4 => 'DK', (int) 5 => 'NO', (int) 6 => 'SE', (int) 7 => 'FI', (int) 8 => 'NL', (int) 9 => 'BE', (int) 10 => 'LU', (int) 11 => 'FR', (int) 12 => 'DE', (int) 13 => 'CH', (int) 14 => 'AT', (int) 15 => 'ES', (int) 16 => 'IT', (int) 17 => 'PT' ) $outsource = true $other_formats = array( (int) 0 => array( 'id' => '1968', 'antibody_id' => '103', 'name' => 'ER alpha Antibody', 'description' => '<p>Alternative names:<strong>ESR</strong>, <strong>ESR1</strong>, <strong>ESRA</strong>, <strong>NR3A1</strong></p> <p><span>Monoclonal antibody raised in mouse against the NH2 terminus of the human <strong>ERα</strong> (estrogen receptor alpha), using a KLH-conjugated synthetic peptide (Q19-K32).</span></p>', 'label1' => 'Validation Data', 'info1' => '<div class="row"> <div class="small-4 columns"> <p><img src="https://www.diagenode.com/img/product/antibodies/C15200009_fig1.png" alt="ER alpha Antibody ChIP Grade" style="display: block; margin-left: auto; margin-right: auto;" /></p> </div> <div class="small-8 columns"> <p><small><strong> Figure 1.

We report that ERα ligand oestradiol (E2) is significantly increased in human cervical cancer (CxCa) tissues and tumour-infiltrating T<sub>reg</sub> cells (CD4<sup>+</sup>CD25<sup>hi</sup>CD127<sup>low</sup>), whereas blocking ERα with the antagonist ICI 182,780 abolishes FOXP3 expression and impairs the function of CxCa infiltrating T<sub>reg</sub> cells. Using a novel approach of co-immunoprecipitation with antibodies to E2 for capture, we identified binding of E2:ERα complexes to FOXP3 protein in CxCa-derived T<sub>reg</sub> cells. Chromatin immunoprecipitation analyses of male blood T<sub>reg</sub> cells revealed ERα occupancy at the FOXP3 promoter and conserved non-coding DNA elements 2 and 3. Accordingly, computational analyses of the enriched regions uncovered eight putative oestrogen response elements predicted to form a loop that can activate the FOXP3 promoter. Together, these data suggest that E2-mediated ERα signalling is critical for the sustenance of FOXP3 expression and T<sub>reg</sub> cell function in human CxCa via direct interaction of ERα with FOXP3 promoter. Overall, our work gives a molecular insight into ERα signalling and highlights a fundamental role of E2 in controlling human T<sub>reg</sub> cell physiology.</p>', 'date' => '2017-12-11', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/29229929', 'doi' => '', 'modified' => '2018-04-24 10:07:53', 'created' => '2018-04-24 10:07:53', 'ProductsPublication' => array( 'id' => '2735', 'product_id' => '1969', 'publication_id' => '3363' ) ) $externalLink = ' <a href="https://www.ncbi.nlm.nih.gov/pubmed/29229929" target="_blank"><i class="fa fa-external-link"></i></a>'include - APP/View/Products/view.ctp, line 755 View::_evaluate() - CORE/Cake/View/View.php, line 971 View::_render() - CORE/Cake/View/View.php, line 933 View::render() - CORE/Cake/View/View.php, line 473 Controller::render() - CORE/Cake/Controller/Controller.php, line 963 ProductsController::slug() - APP/Controller/ProductsController.php, line 1052 ReflectionMethod::invokeArgs() - [internal], line ??
