HSPG2 and hepatocellular carcinoma: The IC50 values of sorafenib were lower in CAPG-silenced HCC cells compared with controls (LM3: 3.842 μM vs. 6.057 μM; 97H: 6.323 μM vs. 8.399 μM; Fig. 5E), whereas IC50 values were higher in CAPG-overexpressing cells (PLC: 5.805 μM vs. 2.740 μM; Huh7: 7.839 μM vs. 4.670 μM; Fig. 5F).
