Analysis of ARID1A-mutated OVISE ovarian clear cell carcinoma (OCCC) cells restored with wild-type ARID1A or treated with GSK126, an inhibitor of epigenetic regulator EZH2. Epigenetic modifier ARID1A is often mutated in OCCC. Results provide insight into the role of epigenetic mechanisms in OCCC.

(Submitter supplied) ARID1A, an epigentic modifier, is often mutated in ovarian clear cell carcinoma (OCCC). In addition, EZH2 is frequently upregulated in OCCC. Inhibtion of EZH2 with an inhibitor (GSK126) selectively inhibits ARID1A-mutated cells. This study was designed to understand changes in gene expression profiles following EZH2 inhibition or ARID1A restoration.

(Submitter supplied) The SWI/SNF chromatin remodeling complex is altered in ~20% of human cancers. ARID1A, a component of the SWI/SNF chromatin-remodeling complex, is the most frequently mutated epigenetic regulator in human cancers. Inactivation of the SWI/SNF complex is synthetically lethal with inhibition of EZH2 activity. EZH2 inhibitors are entering clinical trials for specific tumor types with SWI/SNF mutations. more...

(Submitter supplied) ARID1A, encoding a subunit of the SWI/SNF chromatin remodeling complex, is the most frequently mutated epigenetic regulators in human cancers. ARID1A is mutated in over 50% ovarian clear cell carcinoma, a disease currently has no effective therapy. Here we show that ARID1A-mutated ovarian cancer cells are selectively sensitive to inhibition of HDAC2 activity. HDAC2 interacts with EZH2 in an ARID1A status dependent manner. more...

(Submitter supplied) Metastatic urothelial carcinoma of the bladder is generally incurable with current systemic therapies. Chromatin modifiers are frequently mutated in bladder cancer, with ARID1A inactivating mutations present in 20% of tumors. EZH2 is a histone methyltransferase that acts as an oncogene that functionally opposes ARID1A. In addition, PI3K signaling is activated in over 20% of bladder cancers. Here we show that ARID1A-mutant tumors are more sensitive to EZH2 inhibition than ARID1A-wild-type tumors. more...

(Submitter supplied) ARID1A, encoding a subunit of the SWI/SNF chromatin remodeling complex, is the most mutated epigenetic regulator in human cancers. ARID1A and TP53 mutations are typically mutually exclusive. Therapeutic approaches that correlate with ARID1A mutational status remain a challenge. Here, we show that HDAC6 activity is essential in ARID1A-mutated ovarian cancers. Inhibition of HDAC6 activity using a clinically applicable small molecule inhibitor significantly improved the survival of mice bearing ARID1A-mutated ovarian tumors. more...

(Submitter supplied) CARM1 is an arginine methyltransferase that asymmetrically dimethylates protein substrates on arginine residues. CARM1 is often overexpressed in cancers and stimulates growth. However, clinically applicable therapeutic strategies based on CARM1 expression in cancer remains to be explored. Here we show that epithelial ovarian cancer is among the cancers with the highest CARM1 amplification rates that predicates a shorter survival. more...

(Submitter supplied) Whether cancer driver mutation(s) directly drives cancer immune phenotype and immune tolerance remains a standing question. ARID1A is a core member of the polymorphic BAF chromatin remodeling complex. ARID1A mutations frequently occur in human cancers and drive cancer development. Here, we studied the molecular, cellular, and clinical impact of ARID1A gene status on cancer immunity. We demonstrate that ARID1A mutations, limited expression, and deficiency impair interferon(IFN)-responsive gene chromatin accessibility and expression, resulting in anemic T cell tumor infiltration, weakened tumor immunity, and shortened host survival in many human cancer histologies as well as in murine cancer models, and are negatively associated with immunotherapy response. more...

(Submitter supplied) Upregulation of enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) and its associated histone H3 lysine 27 (H3K27) trimethylation frequently occur in human cancer, yet both preclinical and clinical evidence suggested the very limited benefit of EZH2-targeted therapies. This study investigated the underlying mechanisms from a perspective of EZH2 inhibition-caused histone modification crosstalk. more...
