Fig. 5: ERO1α augmented expression of VEGF-A.

a VEGF-A expression analyzed for 114 pairs of HCC tissues from the HCC cohort described in Fig. 2. Central horizontal line, mean; error bars, SD. b Positive correlation between ERO1α and VEGF-A levels in HCC specimens. c VEGF-A protein by western blots. d RT-qPCR for levels of VEGF-A mRNA in tumor cells. e ELISA for VEGF-A concentration in TCM. Data are mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001
