Tumor tissue and nontumorous tissue of 31 patients with testicular tumor were examined by the peroxidase antiperoxidase (PAP) procedure using the primary antibody against glutathione S-transferase (GST). Histology of primary tumor was classified as seminoma in 10 cases, non-seminoma in 18 (including
BACKGROUND
A small subset of young men die from seminoma. Studying these high risk, clinically atypical seminomas (CASs)-aggressive tumors with visceral metastases and chemotherapy resistance-may provide clues to the nature of drug resistance and the origin of testicular cancers. We explored the
Glutathione sulfhydryl transferase (GST) is believed to play a major role in the detoxification of chemotherapeutic agents and therefore is thought to be important in chemoresistance. Thirty primary testicular germ cell tumors were stained immunohistochemically for GST pi using a rabbit polyclonal
