WebNov 22, 2024 · EZH2, the histone methyltransferase and a member of the polycomb repressive complex 2 (PRC2), catalyzes the trimethylation of lysine 27 on histone 3 and showed a synthetic lethality in ARID1A-mutated ovarian cancer, but its role in GC has not been investigated yet. Methods. WebJan 15, 2016 · We identified PIK3IP1 as a direct ARID1A/EZH2 target, which is upregulated by EZH2 inhibition and contributes to the observed synthetic lethality by inhibiting PI3K/AKT signaling. Significantly, EZH2 inhibition causes regression of ARID1A mutated, but not wild-type, ovarian tumors in vivo.
