In RWPE-1 cells, GLIPR1-ΔTM did not increase the apoptosis induced by any dose of docetaxel, which is consistent with the results of the cell survival assay and our previous data showing that GLIPR1-ΔTM selectively induces apoptosis in PCa cells but not in normal prostate cells. Here, GLIPR1 is linked to posterior cortical atrophy.
