SKLB1002 inhibited tube-like structures formation and VE-cadherin expression of HCT116 cells. a The tube-like structures formed by HCT116 cells with or without SKLB1002 treatment (left). Red arrows indicate the typical tube-like structures. Scale bar: 100 μm; Quantitative analysis of the mean number of tube-like structures and shown as mean ± SD (right). b Protein expressions of VEGFR2, p-VEGFR2, FAK, p-FAK, ERK, p-ERK and VE-cadherin in HCT116 cells with or without SKLB1002 treatment were determined by western blotting analysis. Representative data of three experiments are shown
