Lanthanum Chloride Sensitizes Cisplatin Resistance of Ovarian Cancer Cells via PI3K/Akt Pathway
Abstract
Our previous study manifested that lanthanum chloride (LaCl3) can enhance the anticancer ability of cisplatin (DDP) in ovarian cancer cells. Here, ovarian cancer cells SKOV3 and SKOV3/DDP were subjected to DDP and LaCl3. Cell viability, apoptosis, DNA repair, and PI3K/Akt pathway were detected. LaCl3 induced more cell death and apoptosis caused by DDP in two cell lines, accompanied by upregulation of Bax and Cleaved caspase 3 proteins, and downregulation of Bcl-2 protein. LaCl3 also could decrease RAD51 protein by inactivation of the PI3K/Akt pathway. These data indicated that LaCl3 could be a potential drug to modulate DDP resistance by inactivating of PI3K/Akt pathway and attenuating DNA repair in ovarian cancer.
