As shown above, growth factors (EGF and bFGF) and stimuli (PMA and LPA) that activated downstream oncogenic signaling (such as PKC, MEK/Erk and PI3K/Akt) could elevate the expression of KLF5, then increased VEGFA transcriptional efficiency and promoted bladder cancer angiogenesis. Here, PRRT2 is linked to urinary bladder carcinoma.
