Src expression in a panel of human TCC cell lines. Src expression in a panel of human TCC cell lines. A, Western blot analysis of Src and p-Src in six TCC cell lines (the murine urothelial cell line MBT2 was included as a nonhuman control). B, densitometry measurements showing total Src and p-Src levels relative to the 5637 cell line. C, Western blot analysis of Src and p-Src in RT4 and RT112 cell lines following increasing nanomolar concentrations of dasatinib treatment (0–500 nmol/L from left to right) for 24 hours prior to harvesting.
