  • Hepatoblastoma is the most frequent liver malignancy in children. HepG2 has been discovered as a hepatoblastoma-derived cell line and tends to form clumps in culture. Intriguingly, we observed that the addition of calcium ions reduced cell clumping and disassociated HepG2 cells. The calcium signal is in connection with a series of processes critical in the tumorigenesis. Here, we demonstrated that extracellular calcium ions induced morphological changes and enhanced the epithelial-mesenchymal transition in HepG2 cells. Mechanistically, calcium ions promoted HepG2 proliferation and migration by up-regulating the phosphorylation levels of focal adhesion kinase (FAK), AKT, and p38. The inhibitor of FAK or CaMKⅡ reversed the effect of calcium on HepG2 cells. Moreover, calcium ions decreased cisplatin sensitivity to HepG2 cells. Furthermore, we found that FAK and CaMKⅡ were upregulated in hepatoblastoma. The group with high expression of FAK and CaMKⅡ exhibited significantly lower ImmunoScore as well as CD8+ T and NK cells. CaMKⅡ was positively correlated with PDCD1 and LAG3. Correspondingly, FAK was negatively correlated with TNFSF9, TNFRSF4, and TNFRSF18. Collectively, extracellular calcium accelerates HepG2 cell proliferation and migration via FAK and CaMKⅡ and enhances cisplatin resistance. FAK and CaMKⅡ shape immune cell infiltration and responses in tumor microenvironments, thereby serving as potential targets for hepatoblastoma.
