Down-Regulation of Nfatc1 Suppresses Proliferation, Migration, Invasion, and Warburg Effect in Prostate Cancer Cells.


ABSTRACT: BACKGROUND Prostate cancer (PCa), accounting for 28% of all male cancer cases, is the second leading cause of cancer-related death among men. NFATc1, belonging to the NFAT family, is overexpressed in PCa and is correlated with the risk of recurrence after radical prostatectomy. MATERIAL AND METHODS In the present study, the expression of NFATc, c-myc, and PKM2 in PCa cells was regulated by lentiviruses and then detected by real-time PCR and Western blot analysis. Further, proliferation, invasion, and migration assays were performed. The glucose consumption and lactate production were assessed by biochemical detection. RESULTS We found that NFATc1 down-regulation significantly suppressed the proliferation and Warburg effect of PCa cells, concurrent with a decrease of c-myc and PKM2 expression. Likewise, the abilities of migration and invasion were also inhibited in NFATc1-silenced PCa cells. In addition, NFATc1 down-regulation-induced inhibition of cell proliferation, migration, invasion, and Warburg effect were counteracted by up-regulation of c-myc or PKM2. The expression of PKM2 was positively regulated by NFATc1 and c-myc expression. CONCLUSIONS These results indicate that NFATc1 down-regulation can suppress the proliferation, Warburg effect, and migration and invasion abilities of PCa cells, probably by regulating c-myc and PKM2 expression. NFATc1 may be a potential therapeutic target for PCa and could be used as a diagnosis or prognosis indicator of PCa.
