Digging Deeper into Breast Cancer Epigenetics: Insights from ChemicalInhibition of Histone Acetyltransferase TIP60 . Idrissou, Mouhamed and Lebert, Andre and Boisnier, Tiphanie and Sanchez,Anna and Houfaf Khoufaf, Fatma Zohra and Penault-Llorca, Frédérique andBignon, Yves-Jean and Bernard-Gallon, Dominique Breast cancer is often sporadic due to several factors. Among them, the deregulation of epigenetic proteins may be involved. TIP60 or KAT5 is an acetyltransferase that regulates gene transcription through the chromatin structure. This pleiotropic protein acts in several cellular pathways by acetylating proteins. RNA... |
TIP60/P400/H4K12ac Plays a Role as a Heterochromatin Back-up Skeleton inBreast Cancer. Idrissou, Mouhamed and Boisnier, Tiphanie and Sanchez, Anna and Khoufaf,Fatma Zohra Houfaf and Penault-Llorca, Frederique and Bignon, Yves-Jean andBernard-Gallon, Dominique BACKGROUND/AIM: In breast cancer, initiation of carcinogenesis leads to epigenetic dysregulation, which can lead for example to the loss of the heterochromatin skeleton SUV39H1/H3K9me3/HP1 or the supposed secondary skeleton TIP60/P400/H4K12ac/BRD (2/4), which allows the maintenance of chromatin integrity and plastic... |
