MELK and prostate neoplasm: After first validating the overexpression of MELK mRNA in a second, independent set of PB‐Cre/PtenloxP/loxP and the PB‐Cre/p53loxP/loxPRbloxP/loxP prostate tumour samples (Fig EV3A), we aimed to confirm that MELK expression is also increased at the protein level in these tumours.
