TRPV1 and hepatocellular carcinoma: The qRT-PCR results of F2, GOT2 and TRPV1 showed that 20/20, 19/20, and 16/19 of the HCC tissues exhibited significantly lower expression of F2 (p < 0.001; Figure 7A), GOT2 (p < 0.001; Figure 7B), and TRPV1 (p = 0.006; Figure 7C), respectively, when compared with their corresponding non-tumorous tissues.
