CASC11 and Familial prostate cancer: Consistent with these findings, we also observed higher expression of PRNCR1 in prostate tumor compared to paired normal tissue samples in our study.Cancer susceptibility candidate 11 (CASC11) is another lncRNA that has been shown to be overexpressed in prostate cancer [16], although we did not detect a difference in CASC11 expression between the tumor and normal samples in our study.
