RBM38 and hepatocellular carcinoma: Given that TRMT2A and RBM38 were identified in a prior genome‐wide shRNA screen as modifiers of circRNA abundance without affecting their linear counterparts,[23] we next performed semi‐quantitative RT‐PCR in HCC cells following knockdown of selected RNA‐binding proteins (RBPs)—SF3B4, TRMT2A, and RBM38 (Figure 5F) (TRMT2A and RBM38 were included as controls).
