| 値 | Anti-epidermal growth factor receptor (EGFR) drugs including erlotinib cause a side effect of hypomagnesemia. In lung adenocarcinoma A549 cells, anticancer agents such as cisplatin and doxorubicin dose-dependently increased toxicity, but the effects were significantly suppressed by culturing the cells in low Mg2+ -containing media. To obtain the maximum effect in cancer chemotherapy, it should be necessary to prevent the reduction of body Mg 2+ content. Anti-EGFR drugs inhibit EGF-induced elevation of transient receptor potential melastatin 6 (TRPM6) Mg 2+ channel in renal tubular epithelial NRK-52E cells. Here, we found that rosiglitazone, an antidiabetic drug, and all- trans-retinoic acid (ATRA), a vitamin A derivative, increase the messenger RNA (mRNA) level of TRPM6 in the presence of erlotinib. The rosiglitazone- and ATRA-induced elevation of mRNA level, Mg 2+ influx, and promoter activity of TRPM6 were inhibited by GW-9662, a potent antagonist of peroxisome proliferator-activated receptor (PPAR)γ, and LE135, a retinoic acid receptor (RAR) antagonist, respectively. Rosiglitazone increased the phosphorylation and nuclear localization levels of PPARγ, which were inhibited by GW-9662. In contrast, RAR was mainly distributed in the nuclei under control conditions, which was unchanged by ATRA and LE135. The promoter activity of TRPM6 was inhibited by a mutation in the peroxisome proliferator hormone response element (PPRE). A chromatin immunoprecipitation assay revealed that PPARγ and RAR bind to the PPRE, which was blocked by GW-9662 and LE135, respectively. These results suggest that rosiglitazone and ATRA reverse the reduction in Mg 2+ reabsorption caused by anti-EGFR drugs. | |||||
