EZH2 depletion leads to increased KLF2 mRNA and protein levels. Expression of KLF2 and EZH2 determined by qRT–PCR (a) and (b) immunoblot in five cancer cell lines (U2OS, MDA-MB-231, MCF-7, PC3 and LNCaP cells) following transfection with oligo-type short interfering RNA (siRNA) against EZH2 or scrambled siRNA for 72 h as a transient model. (c) Immunoblot of EZH2 and KLF2 in stable EZH2 knockdown clones. U2OS cells are transfected with shRNA constructs targeting EZH2 or control vector and undergo selection with puromycin. P-values obtained from Student's t-test.
