Metformin treatment impairs the adenine nucleotide translocator activity and energy metabolism in human clear cell renal carcinoma cells.

Although metformin (MET), the well-known antidiabetic drug, exhibits clear antineoplastic effects and is reported to target mitochondria, several issues are still open in this regard, thus limiting its utilization as an anticancer drug alone or in combination with other molecules. Here a functional investigation was carried out to reveal how MET impacted on mitochondrial functions and cell energy metabolism in human cultured clear cell renal carcinoma cells (ccRCCs), in which the anticancer effe...
