Glyoxalase I and glyoxalase II activities have been measured in human tumor and non-tumor samples of 15 kidneys, 15 bladders, 4 testes, 2 adrenals as well as in 4 samples of prostatic adenomas. In all tissues examined glyoxalase I and glyoxalase II activity values varied widely from one patient to another. No significant difference in glyoxalase I activity(More)
We used proteomic approach to analyze the protein profile of human follicular fluid (HFF) obtained from 25 normo-ovulatory women undergoing assisted reproduction techniques due to a male infertility factor. In all HFF samples analyzed we found 695 common spots distributed in the 3 to 10 pH range and in the 10-200 kDa range. Only 625 of these spots were also(More)
Two forms of glutathione transferase were purified from liver cytosol of the sea bass (Dicentrarchus labrax) by GSH-Sepharose affinity chromatography followed by chromatofocusing. The major enzyme (DL-GST-6.7; 75% of total activity bound to the column) has a pI value of 6.7 and is composed of two subunits of apparent molecular mass 26.5 kDa. The minor(More)
Five forms of glutathione transferase (GST) were resolved from the cytosol of adult common toad (Bufo bufo) liver by GSH-affinity chromatography followed by isoelectric focusing. The major enzyme (GST-7.64; 55% of total activity bound to the column) has a pI value of 7.64, is composed of two subunits each with a molecular mass of 23 kDa, and has the(More)
Mesenchymal Stem Cells derived from Amniotic Fluid (AFMSCs) are multipotent cells of great interest for regenerative medicine. Two predominant cell types, that is, Epithelial-like (E-like) and Fibroblast-like (F-like), have been previously detected in the amniotic fluid (AF). In this study, we examined the AF from 12 donors and observed the prevalence of(More)
By using affinity-chromatography and isoelectric-focusing techniques, several forms of glutathione transferase (GSTs) were resolved from human prostate cytosol. All the three major classes of GST, i.e. Alpha, Mu and Pi, are present in human prostate. However, large inter-individual variation in the qualitative and quantitative expression of different(More)
By using affinity chromatography and isoelectric focusing techniques, several forms of glutathione transferase (GSTs) were resolved from human testis obtained from patients operated on for malignant diseases. Large interindividual variations in the expression of different isoenzymes resulted in the samples investigated. Five out of six samples analysed(More)
In the present work, we have studied glutathione transferase (GST) activity and GST subunits distribution in the liver of young and aged rats kept under hypoxic or hyperoxic normobaric conditions as model of oxidative stress. A significant decrease of GST activity was detected in young hypoxic rat liver, whereas a significant increase occurred in aged(More)
Limited proteolysis of glutathione transferase P1-1 (GSTP1-1) by chymotrypsin generates a 34-kDa GSTP1-1 fragment (a dimer of the 17-kDa subunit composed by residues 48-207) containing the whole C-terminal domain and a part (about 15%) of the N-terminal domain (residues 48-76, i.e., the structural elements beta 3, beta 4, and alpha C). The structural and(More)
