ABSTRACT
AIM: To investigate the effect of flutamide on mitochondrial biogenesis and the regulating effect of anoxidative pathway Nrf2 on it. METHODS: Human hepatocyte HepG2 cells were treated with flutamide (0-50 μmol/L) for 24 h, then mtDNA copy number and protein expression of mitochondrial biogenesis were detected by RT-PCR and WB. The effects of ERK1/2 and the role of Nrf2 pathway in mitochondrial biogenesis were further observed by gene knockdown and protein activation/inhibition methods. RESULTS: Flutamide interfered mitochondrial biogenesis concentration-dependently, the mtDNA copy number, ERK1/2 and PGC-1α proteins increased with the dose. ERK1/2 inhibition and activation regulated flutamide-induced mtDNA copy number and PGC-1α expression, and inhibition of Nrf2 pathway also affected flutamide-induced mtDNA copy number and expression of PGC-1α, as well as ERK1/2 expression. CONCLUSION: Flutamide affects mitochondrial biogenesis, and the antioxidant pathway Nrf2 may be involved in the regulation of flutamine-induced mitochondrial biogenesis by regulating ERK1/2.
