Figure Lengend Snippet: NGR2 increased hypoxia in the colon mucosa with an increased ratio of serum VEGFA165/VEGFA121 and increased protein expression of Rap1GAP and TSP1. (A) The protein expression levels of VEGFR2, VEGFR2 (p1175), VEGFR2 (p1214), Rap1GAP, TSP1, and HIF-1α in the colon mucosa; (B,C) the serum contents of VEGFA165 and VEGFA121 and the ratio of VEGFA165/VEGFA121; (D,E) the concentration of intracellular pyruvate and lactic acid in the colonic mucosa. The data are means ± SEM of 3 independent experiments performed in triplicate. One-way ANOVA and Student’s t-test (**, P<0.001 vs. control).
Article Snippet: VEGFA121 (no: SEB851Ra) and VEGFA (no: SEA143Ra) ELISA kits were purchased from Cloud-Clone Co. Anti-VEGFR2 antibody (ab11939), anti-VEGFR2 (phospho Y1214) antibody (ab5475), and anti-Rap1GAP antibody (ab32373) were purchased from Abcam Co. (London, United Kingdom).
