CDCA5 knockdown inhibits ERK signalling pathway activation. (A and B) Western blotting was used to detect the total ERK protein expression levels and ERK phosphorylation levels after CDCA5 knockdown in C4-2 and PC-3 cells. GAPDH was used as an internal control. (C) Representative pictures of the protein expression levels of CDCA5, p-ERK, Ki67 and cleaved caspase-3 in patient specimens. The magnification of the images are ×200 (n=96). CDCA5, cell division cycle-associated 5; ERK, extracellular signal-regulated kinase; sh, short hairpin; CON, control; p-, phosphorylated.
