Fig. 3From: Downregulation of TTF1 in the rat hypothalamic ARC or AVPV nucleus inhibits Kiss1 and GnRH expression, leading to puberty delayTTF1 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 < 0.001Back to article page
