MYBL1 and hepatocellular carcinoma: Strikingly, the data of chick embryo chorioallantoic membrane (CAM) experiments indicated that overexpression of MYBL1 strongly enhanced, whereas downregulation of MYBL1 inhibited, the abilities of neovascularization (Fig. 2C), suggesting that MYBL1 promotes HCC angiogenesis in vitro tube formation assays revealed that.
