TG could Modulate FPN1 in MES 23.5 Cells by Hepcidin

Abstract

Objective To observe the effects of thapsigargin (TG) on ferroportin1 (FPN1) in MES23.5 dopaminergic cell. Methods MES23.5 cells were treated with TG (0.1 μM or 1 μM) for 24h. the mRNA levels of hepcidin were measured using real-time PCR; The protein levels of CHOP, XBP-1s and FPN1 were measured using western blots. Results CHOP and XBP-1s expression was significantly higher in the TG-treated group than that in the control group; hepcidin mRNA levels in TG-treated group were up-regulated, this increase was to a larger extent in the 1 μM TG group when compare with the 0.1 μM TG group; however, FPN1 expression was significantly lower in the TG-treated group, this decrease was to a larger extent in the 1 μM TG group when compare with the 0.1 μM TG group. Conclusion TG could modulate FPN1 in MES23.5 cells by hepcidin.
