KLK6 and neoplasm: The IHC analysis of KLK6 expression in the tumor tissue samples of ApcMin/+ mice and KLK6 expressing CPC;Apcfl/fl mice (CPC;Apcfl/fl;Klk6+/+) confirmed a similar pattern of KLK6 protein localization in the luminal and epithelial areas of the tumors in both mouse models (Figure S2).
