Histone methylation regulates diverse chromatin-templated processes, including transcription. Many transcriptional corepressor complexes contain lysine-specific demethylase 1 (LSD1) and CoREST that collaborate to demethylate mono- and dimethylated H3-K4 of nucleosomes. Here, we report the crystal structure of the LSD1-CoREST complex. LSD1-CoREST forms an elongated structure with a long stalk co...
DNA and histone chromatin modifying enzymes play a crucial role in chromatin remodeling in several biological processes. Lysine-specific demethylase 1 (LSD1), the first identified histone demethylase, is a relevant player in the regulation of a broad spectrum of biological processes including development, cellular differentiation, embryonic pluripotency and cancer. Here, we review recent insigh...
Because of its involvement in the progression of several malignant tumors, the histone lysine-specific demethylase 1 (LSD1) has become a prominent drug target in modern medicinal chemistry research. We report on the discovery of two classes of noncovalent inhibitors displaying unique structural features. The antibiotics polymyxins bind at the entrance of the substrate cleft, where their highly ...
The enzymes that regulate histone methylation states and the protein domains that recognize methylated histone residues have been implicated in a number of human diseases, including cancer, as a result of their ability to affect transcriptional changes by altering chromatin structure. These proteins are recognized as potential therapeutic targets for the treatment of diseases associated with ep...
SUMMARY One intraperitoneal injection of 1 mg of 3-methylchol anthrene into immature male and female rats results in an increase in azo dye demethylase activity. This is followed by an increase in wet and dry liver weight and in total protein, which reaches a peak of about 30†" 40% above control levels within 3 or 4 days. Cell proliferation contributes to the in crease in liver weight and pro...
Gastric epithelial cell malignant transformation induced by Helicobactor Pylori contributes to tumor development, but the underlying mechanisms for this remain unclear. Here we demonstrate that RBP2, a newly identified histone demethylase, can be induced by CagA via PI3K/AKT-Sp1 pathway depending on AKT phosphorylation. Sp1 directly binds to RBP2 promoter and enhances its expression then the up...
Some strains of soil and marine bacteria have evolved intricate metabolic pathways for using environmentally derived aromatics as a carbon source. Many of these metabolic pathways go through intermediates such as vanillate, 3-O-methylgallate, and syringate. Demethylation of these compounds is essential for downstream aryl modification, ring opening, and subsequent assimilation of these compound...
