Glutathione-S-transferase-pi (GST-pi) expression in renal cell carcinoma

Glutathione-S-transferase-pi (GST-pi) expression in renal cell carcinoma

Multidrug resistance correlates with unfavourable treatment outcomes in numerous cancers including renal cell carcinoma. The expression and clinical relevance of Glutathione-S-transferase-pi (GST-pi), a multidrug resistance factor, in kidney tumors remain controversial. We analyzed the expression of GST-pi in 60 formalin-fixed, paraffin-embedded renal cell carcinoma samples by immunohistochemis...

(gst-Pi) in breast carcinoma

Breast carcinoma is the most common cancer and cause of death among females worldwide, including Jordan. The risk factors for breast carcinoma are linked to DNA mutation and failure of DNA repair or detoxification systems. Identification of susceptibility factors that predispose individuals to breast carcinoma if they are exposed to particular environmental agents might give further insight int...

Molecular cloning and expression study of pi-class glutathione S-transferase (pi-GST) and selenium-dependent glutathione peroxidase (Se-GPx) transcripts in the freshwater bivalve Dreissena polymorpha.

Glutathione S-transferases (GST) and glutathione peroxidases (GPx) are essential components of cellular detoxification systems. We identified GST and GPx transcripts in the freshwater bivalve Dreissena polymorpha, their full-length coding sequences were obtained by reverse-transcription PCR using degenerated primers followed by 5' and 3' RACE-PCR (rapid amplification of cDNA ends-PCR). The cDNA...

Glutathione S - transferase pi expression is down-regulated in patients with esophageal squamous carcinoma

Expression of glutathione, glutathione peroxidase and glutathione S-transferase pi in canine mammary tumors

BACKGROUND Glutathione (GSH) is one of the most important agents of the antioxidant defense system of the cell because, in conjunction with the enzymes glutathione peroxidase (GSH-Px) and glutathione S transferase pi (GSTpi), it plays a central role in the detoxification and biotransformation of chemotherapeutic drugs. This study evaluated the expression of GSH and the GSH-Px and GSTpi enzymes ...
