The result showed that various prostate cancer tissue-derived cell lines (MDAPCA2B, VCAP, NCIH660, LNCAP, 22Rv1, PC3) expressed HSP90AB1 at higher levels than the normal-like or ectopically transformed prostate cell lines (PRECLH, WPE1NA22, P4E6, SHMAC4, SHMAC5) (Figure 1H). Here, HSP90AB1 is linked to prostate cancer.
