TYRO3 knockdown systematically resulted in a significant large decrease in cell growth/survival, in all the bladder cancer cell lines tested, regardless of AXL and MERTK expression levels, as previously reported for melanoma cells.30 These results suggest that neither AXL nor MERTK could play a redundant role, rescuing the loss of TYRO3. This evidence concerns the gene TYRO3 and urinary bladder cancer.
