Figure Lengend Snippet: Figure 8. The TGFB1-SMAD2/3 pathway regulates MARCH5, ATG5, and SMAD2 through MIR30A. (A) The TGFB1–SMAD2/3 signal pathway luciferase reporter activity was detected in ectopically expressing MARCH5 ovarian cancer A2780 cells infected with LV5-MARCH5. (B) The TGFB1–SMAD2/3 signal pathway luciferase reporter activity was detected in LV3–1-, LV3–2-, and LV3-NC-infected SKOV3 cells. (C) Ovarian cancer SKOV3 cells were transfected with LV5-GFP, LV5-MARCH5, LV5-MARCH5 C ATG5 siRNA, or LV5-MARCH5 C SMAD2 siRNA. The protein expression of p-SAMD2 was detected by western blot. (Di) The expression of MARCH5, ATG5, and SMAD2 mRNA in SKOV3 cells was regulated by TGFB1 and MIR30A mimics. (Dii) The expression of MIR30A in SKOV3 cells was regulated by TGFB1. (Diii) The expression of MARCH5, ATG5, and SMAD2 mRNA in SKOV3 cells was regulated by LY2109761 and MIR30A inhibitor. (Div) The expression of MIR30A in SKOV3 cells was regulated by LY2109761. (E) The putative binding sites between MIR30A and SMAD2/3. (F) A graphic abstract for the significance of the MARCH5 pathway (MIR30A, SMAD2/3, MARCH5, ATG5, and SMAD2). Data are expressed as mean § SD from 3 independent experiments. p < 0.05, and p < 0.01.
Article Snippet: Detection of protein expression by western blotting The expressions of SMAD2, p-SMAD2, ATG5, MARCH5, and GAPDH proteins were analyzed by western blot.23 The primary antibodies used include polyclonal rabbit anti-MARCH5 (Bioss Biotechnology Company, bs-9339R); rabbit monoclonal to SMAD2 (Abcam, ab40855); rabbit monoclonal to p-SMAD2 (Abcam, ab188334); and polyclonal rabbit anti-GAPDH (Santa Cruz Biotechnology, AB10016).
