Figure Lengend Snippet: PGK1 inhibition improves pregnancy outcomes in vivo and alleviates trophoblast OS in vitro . Schematic diagram of mouse treatments. C) Representative images (B) and fetal quantification (C) of the control group, GDM group, and NG52 group; n=5. (D) H&E staining of mouse placental sections. Up: Overview (scale bar = 1,000 μm). Down: High magnification (scale bar = 100 μm); n = 5. (E) Representative Western blot images of Keap1, Nrf2, Ho-1, and NQO1 in the three groups. (F) IF analysis of ROS levels (red) in mouse placental tissues, and nuclei were counterstained with DAPI (blue); scale bar = 100 μm. Representative IHC staining of 4-HNE in NC, GDM, and NG52-treated mouse placentas. Up: Overview (scale bar = 1 mm). Down: High magnification (scale bar = 100 μm). Representative Western blot images of Keap1, p-Nrf2, Nrf2, Ho-1, and NQO1 levels in HTR8/SVneo cells. OCR measurements. The cells were treated with oligomycin (1.5 μM), FCCP (1 μM) or Rot/AA (0.5 μM) as indicated. The morphology of mitochondria were detected by staining with MitoSox™ red; scale bar = 20 μm. Representative fluorescence images showing MCMP in the various groups; scale bar = 20 μm. Representative fluorescence images showing DCFH-DA (green) staining in HTR8/SVneo cells, and nuclei were counterstained with Hoechst (blue); scale bar = 250 μm. Representative fluorescence images showing MitoSOX staining (red) of HTR8/SVneo cells and nuclei counterstained with Hoechst (blue); scale bar = 100 μm. * represents p < 0.05, ** represents p < 0.01 and ns represents p > 0.05.
Article Snippet: The GDM group (n = 15) was administered vehicle, the NG52 group (n = 5) was administered NG52 (100 mg/kg; MCE, USA) dissolved in 0.5% CMC-Na (Solarbio, China) by gavage, and the estradiol group (n = 5) was intraperitoneally injected with estradiol solution (0.2 mg/kg/day; MCE, USA) dissolved in olive oil from GD 9.5 to GD 18.5.
