ChIP assay analysis of the enrichment of H3R2me1 and H3R2me2s on the promoter of SLC7A11 in the indicated cells treated with PRMT5 inhibitor GSK591 (5 μM, 1 h). ChIP-qPCR of Histone 3 served as the control. The results showed that inhibiting PRMT5 activity using the PRMT5 inhibitor GSK591 significantly reduced the levels of H3R2me1 and H3R2me2s on the SLC7A11 promoter in CPT-treated cells.

The compound dose-response matrix for proliferation inhibition of HCT116 and SW480 cells treated with PRMT5i (GSK591) (10-100 μM; 7 days) and EZH2i (GSK126). Color gradation indicates percentage viability at the indicated dose combination. Combination index (CI) plots for 100 nM PRMT5i (GSK591) (top) or EZH2i (GSK126) (bottom) with graded doses of EZH2i (GSK126) or PRMT5i (GSK591) in HCT116 and SW480 cells.

Immunoblots of PRMT5, EZH2 and CDKN2B (p15INK4b) protein levels in HCT116 and SW480 cells following treatment with PRMT5i (GSK591; 100 nM), EZH2i (GSK126; 100 nM), or PRMT5i (GSK591; 100 nM) + EZH2i (GSK126; 100 nM). GAPDH was used as a loading control. Western blot analysis clearly showed that the selected combination of PRMT5i (GSK591) and EZH2i (GSK126) robustly activated the protein expression of CDKN2B.
