Abstract
In cultured human osteosarcoma (OS) cells, we recently demonstrated that insulin-like growth factors (IGF-1)-induced MG-63 and 143B human OS cells proliferation were consistent with increasing ClC-3 expression, and ClC-3 was up-regulated in cells with high metastatic potency. Blockade of ClC-3 greatly suppressed the phosphorylation activation of Akt/GSK3β. We also found that blockade of ClC-3 effectively down-regulated the expression of cyclin D1 and cyclin E, and caused activation of p27(KIP) and p21(CIP). The synthesized effects on these proteins which play a major role in cell cycle regulation bring about G0/G1 cell cycle arrest in MG-63 cells, and finally abrogate the cell proliferation. Besides, ClC-3 deletion attenuates OS cell migration via down-regulation the expression of MMP-2 and MMP-9. Such information suggests that ClC-3 might be a potential target for anti-OS.
