A validated method has been developed for the simultaneous measurement of reduced and oxidizedglutathione in de-proteinised cellular extracts. This has been used to compare models of malignant andnon-malignant human prostate cell lines. Analysis of LNCaP and DU145 cells showed a glutathione toglutathione disulfide ratio of 8:1 and 32:1 respectively, whilst the control cell line, PZ-HPV7 displayeda ratio of 93:1. Results indicate that the more aggressive phenotype displays adaptation to increasedoxidative stress via up regulation of glutathione turnover. It was also noted that in the LNCaP and DU145cell line, glutathione was only responsible for ca. 60% and 79% respectively, of the total cellular reducedthiol; indicating the presence of other biological thiols.
