WebApr 10, 2024 · Consequently, the DNA-replicative stress caused by ATRX mutations and MYCN amplification causes synthetic lethality in neuroblastoma, representing an uncommon instance in which the inactivation of a tumor-suppressor gene and activation of an oncogene are incompatible. ... (EZH2) inhibition by modulating neuronal gene … WebMay 26, 2024 · Using a synthetic lethality screen of a siRNA library biased toward nuclear enzymes, we identified a number of important regulators of cisplatin resistance in SCLC cells, including EZH2.
WebJun 17, 2024 · Results: We identified the combined inhibition of EZH2 and the proximal DNA damage response kinase ATM as a novel synthetic lethality-based therapy for the treatment of BRCA1-deficient breast tumors. We show that the combined treatment with the EZH2 inhibitor GSK126 and the ATM inhibitor AZD1390 led to reduced colony formation, … WebJun 17, 2024 · In order to identify synthetic lethal partners of EZH2 that are specifically effective in BRCA1-deficient breast cancer, we used BRCA1-deficient and -proficient mammary tumor cell lines to perform a high-throughput drug screen in combination with GSK126. We analyzed a panel of 27 distinct compounds targeting main oncogenic …
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. WebFeb 4, 2016 · Recent studies have extended this antagonistic relationship to cancers linked to the inactivation of other SWI-SNF subunits, as EZH2 inhibition is synthetic lethal in ovarian cancer xenografts ...
WebPIK3IP1 contributes to the observed synthetic lethality. ARID1A and EZH2 respectively belong to the SWI/SNF and polycomb complexes. The antagonistic roles of SWI/SNF and polycomb proteins in gene transcription were initially suggested from genetic studies in Drosophila 17. We sought to determine whether the observed phenotypes are due to ...
