Fig. 5From: Circular RNA P4HB promotes glycolysis and tumor progression by binding with PKM2 in lung adenocarcinomacircP4HB can bind to PKM2. A circP4HB is mainly located in the cytoplasm. B RIP assay showed circP4HB can bind to circP4HB. CircP4HB can regulate the expression of PKM2 in transcriptional level (C, D) but protein level (E). F Western blot confirmed the interaction between PKM2 and circP4HB after pull down (*p < 0.05, ***p < 0.001)Back to article page
