STK25 and cancer: Yet upon investigation of STK25 deletion in CBioportal [14], a deep deletion frequency of 1% is reported and the only protein staining data in prostate tissue suggest an increase in STK25 is seen in cancer [45] which is contradictory to samples detailed in the Human Protein Atlas, where 7 samples out of 11 PCs had no detectable expression of STK25 (www.proteinatlas.org) [16].
