WebFeb 23, 2024 · Although the mammalian SIRT1 protein is also known to deacetylate p53 (Langley et al., 2002), the lack of any significant rescue of the abnormalities of Sirt1-deficient mice by loss of p53 (Kamel et al., 2006) clearly suggests, when viewed alongside our results, distinct roles for SIRT1 and for SIRT6 in the modulation of p53 activity and aging ... WebDec 19, 2005 · HDAC1 can deacetylate E2F1 via an indirect interaction mediated by Rb. Given the fact that Rb-bound E2F promotes deacetylation and that the lysines that are targets of acetylation and deacetylation are only conserved among the proliferation-promoting E2Fs strongly suggests that E2F acetylation is coupled to proliferation.

WebHDACs also deacetylate proteins such as p53, E2F1, RelA, YY1, TFIIE, BCL6 and TFIIF (Glozak et al. 2005). Histone deacetylases are targeted by structurally diverse compounds known as HDAC inhibitors (HDIs) (Marks et al. 2000). These can induce cytodifferentiation, cell cycle arrest and apoptosis of transformed cells (Marks et al. 2000, Bolden ... WebSIRT2 is also highly expressed and responsible for cell proliferation, invasion, and tumor growth in leukemia, neuroblastoma, HCC, and pancreatic cancer. SIRT2 is known to inhibit p53 such that the diminishment of SIRT2 activity was shown to reduce p53 acetylation and activate apoptosis in cancer cell lines.

WebThe above results suggest that Rh4 induces apoptosis in EMT-6 cells by regulating HDAC2 expression. Meanwhile, a recent study has demonstrated that HDAC2 can bind and deacetylate PD-L1 in breast cancer cells, which indicates that HDAC2 also plays a unique role in maintaining PD-L1 function [59]. Histone deacetylases (EC 3.5.1.98, HDAC) are a class of enzymes that remove acetyl groups (O=C-CH3) from an ε-N-acetyl lysine amino acid on both histone and non-histone proteins. HDACs allow histones to wrap the DNA more tightly. This is important because DNA is wrapped around histones, and DNA expression is regulated by acetylation and de-acetylation. HDAC's action is opposite to that of histone …
