NUAK1 and medullary breast carcinoma: Analysing the GSE21653 database,29 we investigated NUAK1 and miR-622 expression also in medullary breast cancer patients, and Kaplan–Meier disease-free survival curve showed that low level of NUAK1 is significantly correlated with disease-free survival (p = 0.02) (Fig. 4b, right).
