CXCL8 and liver cancer: Furthermore, in other cell types than U2OS cells, including HepG2 (human liver cancer cells) and HeLa (human cervical cancer cells), upon sub-lethal doses of CDDP, at below 5 μM and 10 μM, respectively (Figures 1F and 1G), EA pretreatment substantially elevated the number of SA-β-gal-positive cells (Figures 1H and 1I; S5B and S5C) and IL-8 mRNA levels (Figures 1J and 1K).
