Quantification of relative phosphorylation expression (the expression of p-mTORC, p-TIE2, p-AKTSer473, p-AKTThr308, and pERK1/2 relative to the corresponding total protein expression) in L914F-iVECs and L914F-iVECs treated with bosutinib.n= 3 biological replicates. Data are expressed as mean SEM. Students t test was used to compare two groups. Phosphorylation proteins and total proteins were quantified separately relative to GAPDH, and then phosphorylation levels were calculated by measuring phosphorylation/total protein expression.
