Figure Lengend Snippet: dDNMT activates TRAIL-death receptor signaling in VHL -deficient ccRCC cells (A) Volcano plot of SGI1027-induced and -repressed genes in RCC10 cells ( n = 2 biological replicates). FC, fold change. (B) Biocarta pathway enrichment analysis of SGI1027-induced genes in RCC10 cells. (C) RT-qPCR analysis of TNFSF10 , TNFRSF10A , TNFRSF10B , and TNFRSF10D mRNA levels in RCC10 cells treated with vehicle or SGI1027 for 2 days ( n = 3 biological replicates). (D and E) Immunoblot analysis of TRAIL, DR4, DR5, DcR2, pro-caspase-10, and cleaved caspase-10 (C-caspase-10) proteins in isogenic RCC10 cells treated with vehicle, SGI1027 (D and E, n = 2 biological replicates), MS1129 (E, n = 2 biological replicates), or decitabine (E, n = 2 biological replicates) for 2 or 7 days. (F) Global m5C levels in RCC10 cells treated with vehicle or SGI1027 for 2 days by ELISA assay ( n = 3 biological replicates). (G–J) MeDIP-qPCR assay in RCC10 cells treated with vehicle or SGI1027 for 2 days ( n = 3 biological replicates). (K–M) DNMT1, DNMT3A, and DNMT3B ChIP-qPCR assay in RCC10 cells ( n = 3 biological replicates). (N) Scheme of dDNMT-activated apoptotic pathway. Data represent mean ± SEM. p value was determined by bioinformatics with edgeR (A) or gene set enrichment analysis (B), unpaired 2-tailed Student’s t test (C and F), two-way ANOVA with Tukey’s test (G–I), and one-way ANOVA with Dunnett’s test (K–M).
