Despite the preponderant role of TYRO3 in the control of bladder cancer cell growth/survival, we cannot rule out the possibility that AXL or MERTK knockdown affects other processes known to be regulated by TAM receptors, such as cell migration, and that long term inhibition of AXL or MERTK could impact tumour cell viability.31 This evidence concerns the gene MERTK and urinary bladder carcinoma.
