GSK343

Notably, we further found that the status of NRF1 expression affected the sensitivity of human cancer cells to EZH2is, including GSK343 and tazemetostat. In conclusion, our findings reveal that NRF1 is a dominant cause of EZH2 overexpression in human cancers and that NRF1 overexpression increases the sensitivity of cancer cells to EZH2is. Active NRF1 and EZH2 expression may be a useful combined predictor for the treatment of cancers with EZH2is.

GSK343 overcame resistant dGSC protection to trigger cell death by a mechanism involving oxidative stress. To conclude, GSK343-mediated EZH2 inhibition efficiently eliminated resistant GSC through ferroptosis, in a H3K27me3-independent manner.

EZH2 is highly expressed in ATC, and its inhibitors EPZ6438 and GSK343 have anti-cancer potential. Two types of nanoparticles were successfully constructed with good sustained-release, targeting effects, and biosafety. They could improve the therapeutic efficacy and reduce toxic side effects, with GSK343-BSA@CS showing significant effects.

This work discovered the precise epigenetic mechanism involving histone methylation responsible for such changes in MSC phenotype. By inhibiting the histone methylation by GSK343, this study showed that MSC phenotype can be maintained over serial passaging as demonstrated by microscopy, multi-omics, and in vitro functional assays.

These findings demonstrate that CSCs and non‑CSCs respond differently to epigenetic modulation, suggesting that personalized combination therapies targeting both subpopulations may be necessary to improve treatment outcomes for ACC. Although these targeted therapies are still in the early stages of investigation, our study provides a promising pre-clinical foundation for the development of effective, personalized therapeutic strategies for this challenging malignancy.

Thus, EZH2 promotes TNFα-driven inflammation, contributing to endometriosis. Targeting EZH2, as with GSK343, could be a promising therapeutic strategy for endometriosis treatment.

Molecular docking analyses predicted most probable inhibitors of EZH2. We employed several predictive analysis tools and identified GSK343, as a promising inhibitor of EZH2.

EZH2-mediated H3K27 trimethylation silences miR-137 in CRC cells by increasing chromatin compaction, reversible by EZH2 siRNA or inhibitor GSK343...It regulates the Wnt signaling pathway by targeting RNF4, leading to c-Myc and β-catenin destabilization. Restoring miR-137 or inhibiting RNF4 suppresses CRC cell proliferation, migration, invasion, and tumor growth, highlighting its therapeutic potential in CRC.

Exposure to GSK343 or ATRA results in inhibition of cell proliferation and induction of cellular senescence, where GSK343 shows a dominant effect. The Figure was created with Biorender.com.

Our results support further investigation of HMT inhibitor combinations as a therapeutic approach in NB.

To perturb the super-silencers, we applied combinational treatment of an enhancer of zeste homolog 2 inhibitor GSK343, and a repressor element 1-silencing transcription factor inhibitor, X5050 ('GR')...Moreover, GR synergistically upregulated super-silencer-controlled genes related to cell cycle, apoptosis and DNA damage, leading to anticancer effects in vivo. Overall, our data demonstrated a super-silencer example and showed that GR can disrupt super-silencers, potentially leading to cancer ablation.

Moreover, GSK343 reduced the expression of inflammatory mediators; eNOS and TGFβ, markers of angiogenesis; and CD31 and CD34, markers of micro vessel density, respectively. In conclusion, our data demonstrate that GSK343 counteracts oral cancer progression through EZH2/Wnt/β-catenin pathway modulation, suggesting that it could be a promising therapeutic approach for OSCC management.
