ENTPD1 and hepatocellular carcinoma: In MDA-MB-231 and HCC-1937 cell lines (WT/shPANX1/shCTRL), we explored the relationship between PANX1 expression and ENTPD1/NT5E expression and found no significant correlation between PANX1 expression and ENTPD1/NT5E expression at the cell line level (p > 0.05; Turkey’s test; Supplementary Figure S2C,D).
