Correlation analyses of NUAK1 and NUAK2 mRNA levels were performed with mRNA levels of calponin as a marker for smooth muscle cells, keratin-19 as a maker for glandular, epithelial cells, tyrosin hydroxylase as a marker for catecholaminergic neurons and PSA as a marker for BPH in human prostate tissues. Here, NUAK1 is linked to benign prostatic hyperplasia.
