NCBI Summary:
This gene encodes a member of the peptidase family. The protein forms a homodimer that hydrolyzes dipeptides or tripeptides with C-terminal proline or hydroxyproline residues. The enzyme serves an important role in the recycling of proline, and may be rate limiting for the production of collagen. Mutations in this gene result in prolidase deficiency, which is characterized by the excretion of large amount of di- and tri-peptides containing proline. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Oct 2009]

Increased Prolidase Activity and Oxidative Stress in PCOS. Hilali N et al. AIM: Matrix metalloproteinases (MMPs) have been considered to have a role in various pathological processes including inflammatory response, cardiovascular disease, and recently also in ovarian dysfunction. Since prolidase could be accepted as a matrix metalloproteinase, on the biochemical level, we aimed to evaluate serum prolidase activity and oxidative-antioxidative status in patients with polycystic ovary syndrome (PCOS) and healthy individuals. MATERIALS AND METHODS: Thirty-three PCOS patients and twenty-eight healthy nonhyperandrogenic women were studied. Levels of prolidase activity, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), luteinizing hormone (LH), follicle-stimulating hormone (FSH), total testosterone (T) and prolactin (PRL) were calculated. RESULTS: Levels of prolidase activities, total oxidant status, oxidative stress index, LH, PRL, and T were significantly higher in PCOS group than in the control group. Total antioxidant status levels were lower in PCOS group than healthy group but it was not statistically significant. There was no significant difference between PCOS and control groups in term of FSH. CONCLUSION: Women with PCOS have increased serum prolidase activity, and oxidative stress. It might be hypothesized that elevated serum prolidase activity, and oxidative stress may be associated with increased cardiovascular risk in PCOS and/or menstrual irregularities associated with this syndrome. 2012 Blackwell Publishing Ltd.
