KDM6
KDM6 family histone demethylases, primarily KDM6A (UTX) and KDM6B (JMJD3), function as H3K27me3 demethylases that remove a key repressive chromatin mark and thereby promote transcriptional activation of developmentally regulated genes[1][2]. Mechanistically, KDM6A and KDM6B counteract Polycomb-mediated gene silencing by catalyzing H3K27me3 demethylation, enabling chromatin remodeling and activation of lineage-specific transcriptional programs[1][2]. This epigenetic activity is closely linked to HOX gene regulation, cellular differentiation, and normal developmental processes, highlighting the central role of KDM6 proteins in chromatin-dependent gene control[1]. In disease settings, dysregulated KDM6A/KDM6B activity alters H3K27me3 distribution and contributes to transcriptional abnormalities associated with cancer, inflammatory disorders, and other pathological conditions[3]. Compared with related isoforms, KDM6A and KDM6B share H3K27 demethylase activity but exhibit distinct biological functions, expression patterns, and disease associations, indicating that individual family members can regulate context-dependent transcriptional programs[1][3]. For experimental applications, the small-molecule inhibitor GSK-J4 is widely used to suppress KDM6A/KDM6B-mediated H3K27 demethylation, increase cellular H3K27me3 levels, and investigate the functional consequences of KDM6 inhibition in disease models and cellular systems[3][4]. Therefore, KDM6 proteins represent important epigenetic regulators and experimentally tractable targets for studies of chromatin regulation, development, inflammation, and cancer biology[1][3].

XL177A (GMP)
0 ImagesCat. No.: HY-138794GCAS No.: 2417089-74-6XL177A GMP is XL177A (HY-138794) produced by using GMP guidelines. GMP small molecules works appropriately as an auxiliary reagent for cell therapy manufacture. XL177A is a covalent USP7 inhibitor that blocks the deubiquitinase activity of USP7. XL177A destabilizes non-canonical PRC1 complexes or KDM6A and reduces chromatin deposition of H2AK119Ub, thereby relieving the repression of neuronal differentiation programs. Meanwhile, XL177A also regulates the ELOF1-UVSSA-USP7-nuclear β-catenin axis, decreasing the transcription levels of related proteins and the accumulation of nuclear β-catenin. XL177A exerts antiviral effects by reducing the expression levels of coronavirus receptors, and exhibits inhibitory activity against APC-mutated colorectal cancer cells, neuroblastoma, and coronaviruses including SARS-CoV-2 variants. XL177A is mainly used in studies related to colorectal cancer, neuroblastoma, and coronavirus infections.
