RNAscope of RP tissue from ICC1-7 and an additional extended independent cohort showed increased SCHLAP1 expression in ICC/IDC compared to benign prostate epithelial cells and Gleason pattern 3, Gleason pattern 4 non-ICC (NC) and Gleason pattern 5 prostate cancer (Fig. 3d, e). Here, SCHLAP1 is linked to prostate cancer.
