Decreased activity of liver glutathione peroxidase in human hepatocellular carcinoma

Glutathione and GSH-dependent enzymes in patients with liver cirrhosis and hepatocellular carcinoma.

“…The obtained results agree with other studies which have shown decreased GSH content, increased MDA level and changes in activities of GSH related enzymes (Casaril et al, 1985;1994;Corrocher et al, 1986;Skrzydlewska et al, 2003).…”

A comparative study of using free radical generators in the testing of chosen oxidative stress parameters in the different types of cells

“…On the other hand, they found no differences in enzyme activity in primary cultures of cells derived from prostate cancer and non-neoplastic cells. Our studies seem to confirm this observation, due to the fact that the determined SOD activity was not significantly different in cancer cells when compared to non-neoplastic cells, although in other studies (Casaril et al, 1985; Rossi et al, 1983), reduced SOD activity was observed in human liver cancer cells as compared to non-neoplastic cells.…”

“…A decreased level of GSH-Px in human hepatoma was reported by Casaril et al [16]. Also, Bartkowiak and Bartkowiak [17] showed that the activity of CAT was distinctly lower in hepatoma-bearing rats than in normal rats.…”
