Effects of PZH on the expression of HIF-1 and VEGF-A in HCT-8. (a) mRNA expression levels of HIF-1 were analyzed by RT-PCR, and α-tubulin was used as a loading control. (b) Protein expression levels of HIF-1 were analyzed by Western blot, and -actin was used as a loading control. (c) Secreted VEGF protein was analyzed by ELISA. #A significant difference compared with normoxic control (). A significant difference compared with hypoxic control ().
