TTF1 gene overexpression in GT1–7 cells promoted the expression of Kiss1. GT1–7 cells were infected with TTF1 overexpression plasmids for 72 h. a EGFP (green) was measured with immunofluorescence microscopy. Optical microscopy was used to obtain bright field images. b TTF1, Kiss1 and GnRH mRNA levels were analysed with qRT-PCR after transfection. Cells transfected with LV-EGFP were used as a negative control. c TTF1 and Kiss1 protein concentrations were determined by western blotting analysis. TTF1-OE, TTF1-overexpression group. NC, lentivirus negative control group. Scale bars, 200 μm a. The results are shown as the mean ± S.E.M. ***P < 0.001
