Fig. 7. Inhibitory effects of EGFL6 knockdown on tumor growth and angiogenesis.
a EGFL6 knockdown inhibited the activation of the AKT/MAPK pathways but did not affected the OC2/VEGFA axis in Skov3, followed by Western blotting assay. b CCK-8 assay showed that EGFL6 knockdown inhibited Skov3 proliferation. c Representative images and quantitation of HUVECs tube formation. d Effect of EGFL6 knockdown on transplanted tumor growth from Skov3, the stripped tumors, tumor size, and tumor weight as indicated (n = 3). e Representative images and quantitation of the microvessels and the OC2/VEGFA/EGFL6 axis of stripped tumors, followed by IHC assay. The tubes (c) and spots (e) were calculated by ImageJ software and statistically analyzed in five random fields; scale bars: 50 μm (c), 100 μm (e). Data are shown as mean ± SD of three independent experiments. *P < 0.05; **P < 0.01.
