Abstract

Prostate stem cell antigen (PSCA) is a glycosylphosphatidylinositol (GPI)‑anchored cell surface protein and exhibits an organ‑dependent expression pattern in cancer. PSCA is upregulated in prostate cancer and downregulated in gastric cancer. PSCA is expressed in a variety of human organs. Although certain studies previously demonstrated its expression in the mammalian and avian brain, its expression in the human brain has not been thoroughly elucidated. Additionally, it was previously reported that PSCA is weakly expressed in the astrocytes of the normal human brain but aberrantly expressed in glioma, suggesting that PSCA is a promising target of glioma therapy and prostate cancer therapy. The current study identified PSCA expression in the neural and choroid plexus cells of the normal human brain by immunohistochemistry. In brain tumors, PSCA was expressed in medulloblastoma and glioma, and its expression was also observed in papilloma and papillary carcinoma of the choroid plexus, ependymoma and meningioma. The results suggest that PSCA may have a tumor‑promoting function in brain tumors and is a potential target for their therapy. However, its expression in normal neuronal and choroid plexus cells implies that a PSCA‑targeted therapy may lead to certain adverse phenomena.
