An endogenous and ectopic expression of metabotropic glutamate receptor 8 (mGluR8) inhibits proliferation and increases chemosensitivity of human neuroblastoma and glioma cells
The present study aimed to determine the role of metabotropic glutamate receptor 8 (mGluR8) in tumor biology. Using various molecular approaches (RNAi or GRM8 cDNA), cell clones with downregulated (human neuroblastoma SH-SY5Y and human glioma LN229) or overexpressed (human glioma U87-MG and LN18 cell lines) mGluR8 were generated. Next, comparative studies on cell proliferation and migration rates, induction of apoptosis and chemosensitivity were performed among these clones. The mGluR8-downregulated SH-SY5Y clones proliferated faster and were more resistant to cytotoxic action of staurosporine, doxorubicin, irinotecan and cisplatin when compared to control cells.
