Proteomic signatures of infertile men with clinical varicocele and their validation studies reveal mitochondrial dysfunction leading to infertility

引用

Asian Journal of Andrology 2016年第2期18卷 282-291,J0007页

作者： Ashok Agarwal Rakesh Sharma luna Samanta Damayanthi Durairajanayagam Edmund Sabanegh American Center for Reproductive Medicine Cleveland Clinic Cleveland OH USA Department of Zoology School of Life Sciences Ravenshaw UniversityCuttack - 751 003 Odisha India Faculty of Medicine MARA University of Technology (UiTM) Selangor Darul Ehsan Malaysia Department of Urology Cleveland Clinic Cleveland OH USA.

To study the major differences in the distribution of spermatozoa proteins in infertile men with varicocele by comparative proteomics and validation of their level of expression. The study-specific estimates for each varicocele outcome were combined to identify the proteins involved in varicocele-associated infertility in men irrespective of stage and laterality of their clinical varicocele. Expression levels of 5 key proteins （PKARIA, AK7, CCT6B, HSPA2, and ODF2） involved in stress response and sperm function including molecular chaperones were validated by Western blotting. Ninety-nine proteins were differentially expressed in the varicocele Eroup. Over 87% of the DEP involved in major energy metabolism and key sperm functions were underexpressed in the varicocele group. Key protein functions affected in the varicocele group were spermatogenesis, sperm motility, and mitochondrial dysfunction, which were further validated by Western blotting, corroborating the proteomics analysis. Varicocele is essentially a state of energy deprivation, hypoxia, and hyperthermia due to impaired blood supply, which is corroborated by down-regulation of lipid metabolism, mitochondrial electron transport chain, and Krebs cycle enzymes. To corroborate the proteomic analysis, expression of the 5 identified proteins of interest was validated by Western blotting. This study contributes toward establishing a biomarker ＂fingerprint＂ to assess sperm quality on the basis of molecular parameters.

Response of testicular antioxidant enzymes to hexachlorocy clohexane is species specific

引用

Asian Journal of Andrology 2002年第3期4卷 191-194页

作者： luna Samanta G.B.N. Chainy Biochemistry Unit & ICABPS Department of Zoology Utkal University Bhubaneswar-751004 IndiaBiochemistry Unit & ICABPS Department of Zoology Utkal University Bhubaneswar-751004 India

Aim: To find out whether the response of testicular oxidative stress parameters to hexachlorocyclohexane (HCH) is species specific. Methods: In rats and mice (n=5 in each group), HCH was administered at a dose of 20 mg/kg/day intraperitoneally for 30 days in 0.1 ml of refined groundnut oil. The control groups received equal volume of the vehicle. Animals were sacrificed 24 hours after the last injection and various oxidative stress parameters were measured immediately. Results: The level of both endogenous as well as FeSO_4 and ascorbic acid-stimulated lipid peroxidation was increased significantly in the HCH-treated rats, whereas the pattern was just the reverse in case of mice. Although the level of H_2O_2 content increased in response to HCH in both groups, a totally different trend was observed for the activity of the principal H_2O_2-metabolising enzyme, catalase. In case of rats, a significant decline in the activity of catalase was recorded in response to HCH whereas a sharp augmentation in the enzyme activity was noticed in mice. Similarly, the decreased activity of superoxide dismutase observed in rats remained unaltered in mice. Conclusion: HCH induces oxidative stress in the testis of both rats and mice. However, the pattern of response of testicular oxidative stress parameters seems to be species specific.
