Tumor vascularization and metastasis are enhanced in betaIV‐ECKO mice. (A, B) Immunoblots show the level of endogenous betaIV‐spectrin along with the indicated receptor levels and activation of VEGF signaling effectors in freshly isolated primary ECs from control versus betaIV‐ECKO tumors. Graphs represent densitometry quantifications based on three biological repeats normalized to beta‐actin loading control. p values are indicated in each graph. (C) Shown are representative IHC images of tumor sections stained with CD31 (indicated by black arrows). (D, E) Graphs show the number of vessels counted per mouse tumor section and the cross‐section area of individual blood vessels (n = 6 mice for control and betaIV‐ECKO). * p = 0.003 relative to control group. (F) Shown are representative images of lung and brain isolated from control and betaIV‐ECKO mice at necropsy. (G) Graph represents the average number of metastatic tumor nodules on the surface of different tissues per mouse (n = 7 mice for control and n = 8 for betaIV‐ECKO mice). Error bars represented by SEM. *p < 0.04 relative to control.
