VEGFC and hepatocellular carcinoma: It would be interesting to explore whether TNF, IL-6, IL-8 or MYC play a role in angiogenesis and disease progression in HCC, and explore the correlation between the expression of these genes and VEGFC. The regulatory mechanism by which upregulation of URG4/URGCP modulates the NF-κB/VEGFC pathway and enhances the angiogenic capacity of HCC cells remains to be elucidated and should be investigated further.
