Significantly, when the effects of Mer and Axl knockdown were compared, Mer inhibition was found to achieve a more complete blockade of tumour growth, while Axl knockdown improved chemosensitivity more robustly.6 These results indicate that Axl and Mer can promote the survival of NSCLC and enhance chemoresistance. Here, MERTK is linked to non-small cell lung carcinoma.
