STIM1 and hepatocellular carcinoma: Western blotting results demonstrated a reduction in the phosphorylation/dephosphorylation ratios of total NFATc2 protein in Hep3B (from 1.00 to 0.32) and MHCC97H (from 1.00 to 0.13) SR HCC cells, along with an increase in the amount of nuclear NFATc2 protein, indicating higher STIM1 expression.
