Figure 4. Knockdown of PBRM1 expression in RCC cell lines.
(A) Verification of PBRM1 knockdown by western blotting. (B)Silencing PBRM1 increased the proliferation of ACHN and 786-O with wild type PBRM1, but not A704 with a homozygous PBRM1 truncating mutation. Data represent means of triplicate experiments with standard deviation, p<0.01. (C) Knockdown of PBRM1 enhanced colony formation in SN12C cells. Data represent means of triplicate experiments with standard deviation, p<0.01. (D) Knockdown of PBRM1 enhanced cell migration in 786-O, SN12C and TK10 cells. Data represent means of triplicate experiments with standard deviation, p<0.01. (E) Gene sets that are most significantly deregulated following PBRM1 knockdown in three RCC cell lines using curated gene sets obtained from MSigDB (http://www.broadinstitute.org/gsea/msigdb/) and additional curated gene sets obtained from the PGSEA package (see Supplemental Material for details).
