WebMar 13, 2024 · Aminopeptidase N (APN) converts cysteinyl-glycine-conjugates into cysteine-conjugates which are, after entering into the PTECs, further metabolized to highly reactive and nephrotoxic thiols by enzymic activity of cysteine-S-conjugate beta-lyase (CCBL) [22, 44]. Having in mind that, among all tissues, GGT has the highest activity in … WebThis hypothesis was tested by pre-treating C57BL/6j mice with suramin prior to cisplatin. Our data indicates that suramin protects the kidney from injury by decreasing cisplatin-induced decreases in kidney function. Renal histology indicated that suramin significantly protected from cisplatin-induced AKI. Data indicate that suramin
WebMay 1, 2003 · Cisplatin cytotoxicity was judged by its antiproliferative action. Incubations with GSH were performed in the presence and in the absence of the dipeptide GlyGly (20 mM), added as an acceptor for the transpeptidation reaction [15] to replace the physiological acceptor cystine [18].

WebAug 1, 2007 · Cisplatin/cysteinyl-glycine complexes were also found in the supernatant of GGT-transfected cisplatin-resistant HeLa cells ; this finding seems to indicate a poor membrane permeability of thiol/cisplatin complexes. It shouldalso be considered that cysteinyl-glycine reacts with cisplatin, approximately fivefold faster than GSH . WebCisplatin (24 mg/kg body weight) was given by a single intraperitoneal injection. Mice were killed at day 1 or day 3 after cisplatin administration, blood and kidney samples were harvested for further analysis.
