A1CF and neoplasm: FCM data indicated that overexpression of A1CF decreased apoptosis (Figures S1B,F and S2A,E), whereas A1CF knockdown increased apoptosis (Figure S2C,D,G,H) of OSRC-2 and 786-O cells, which is consistent with the reported results in other tumor cells [17,18] or kidney epithelial cells [13].
