The Ameliorating Effect of Berberine-Rich Fraction against Gossypol-Induced Testicular Inflammation and Oxidative Stress. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2018; 2018:1056173. [PMID: 29849861 PMCID: PMC5903196 DOI: 10.1155/2018/1056173] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/22/2017] [Accepted: 02/17/2018] [Indexed: 01/07/2023]
Abstract
This study was aimed at evaluating the efficacy of berberine-rich fraction (BF) as a protective and/or a therapeutic agent against inflammation and oxidative stress during male infertility. Sexually mature Sprague-Dawley male rats were divided into five groups treated with either corn oil, BF (100 mg/kg BW, orally, daily for 30 days), gossypol acetate (5 mg/kg BW, i.p.) eight times for 16 days, BF alone for 14 days then coadministered with gossypol acetate for the next 16 days (protected group), or gossypol acetate for 16 days then treated with BF for 30 days (treated group). All animals completed the experimental period (46 days) without obtaining any treatments in the gap period. Sperm parameters, oxidative index, and inflammatory markers were measured. Gossypol injection significantly decreased the semen quality and testosterone level that resulted from the elevation of testicular reactive oxygen and nitrogen species (TBARS and NO), TNF-α, TNF-α-converting enzyme, and interleukins (IL-1β, IL-6, and IL-18) by 230, 180, 12.5, 97.9, and 300%, respectively, while interleukin-12 and tissue inhibitors of metalloproteinases-3 were significantly decreased by 59 and 66%, respectively. BF (protected and treated groups) significantly improved the semen quality, oxidative stress, and inflammation associated with male infertility. It is suitable to use more advanced studies to validate these findings.

Abstract
Previous studies have demonstrated that the polycomb repressor Bmi1 is universally expressed in all types of testicular cells and might regulate the spermatogonia proliferation, however, it is unclear whether Bmi1 plays a critical role in maintaining normal male fertility in vivo. To answer this question, we first confirmed that Bmi1 is universally expressed in all types of testicular cells and found that the gene relative expression levels of Bmi1 in testis were the highest relative to other organs. Then we investigated the role of Bmi1 in maintaining normal male fertility using Bmi1 knockout male mouse model. Our results demonstrated that Bmi1 deficiency resulted in totally male infertility with smaller testis, severe oligospermia and sperm malformation. Mechanistically, decreased serum testosterone levels with down-regulating 3βHSD and 17βHSD expression levels, reduced germ cell proliferation, increased germ cell apoptosis with up-regulating p16, p19, p53 and p21 expression levels, increased reactive oxygen species (ROS) and H2O2 levels with down-regulating gene expression levels of anti-oxidant enzymes, and increased 8-OHdG and γ.H2AX positive cells in testis were observed in Bmi1 deficient mice compared with wild-type mice. These results indicate that Bmi1 deficiency results in male infertility by reducing testosterone syntheses, increasing oxidative stress and DNA damage, activating p16 and p19 signaling pathway, inhibiting germ cell proliferation and inducing germ cell apoptosis and sperm malformation. Thus, Bmi1 may be a novel and potential target for the clinic treatment of male infertility.

Protective effects of thornback ray muscle protein hydrolysate against dyslipidemia, oxidative stress and reduced fertility induced by high cholesterol diet in adult male rats. RSC Adv 2018; 8:22303-22312. [PMID: 35539733 PMCID: PMC9081093 DOI: 10.1039/c8ra00657a] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Accepted: 06/03/2018] [Indexed: 12/31/2022] Open
Abstract
Enzymatic thornback ray (Raja clavata) muscle hydrolysates have been shown to have antioxidant and antihypertensive activities in vitro. The Neutrase hydrolysate exhibited the highest activities, so it was investigated along with the undigested muscle to test their hypolipidemic, antioxidative and fertility effects in rats fed with a high-cholesterol diet (HCD). Animals were allocated into four groups of 5 rats each: a normal diet group (control), a HCD group, and two groups of HCD with a daily dose of undigested muscle (Und) or the hydrolysate (MH) at 0.7 g kg−1 of body weight. All animals received their respective treatments daily for 1 month. After the treatment period, serum lipid profiles, the activities of alanine aminotransferase and aspartate aminotransferase, the level of malonaldehyde, the activities of antioxidant enzymes (catalase and glutathione peroxidase) in the liver and sperm fertility parameters (in the epididymis and testis) were determined. Compared with those fed a standard diet, HCD induced dyslipidemia and oxidative stress, and decreased numerous reproductive parameters (mobility, count and viability). Interestingly, supplementing the HCD with thornback ray proteins attenuated all these anomalies, especially in the case where they were hydrolysed. These observations suggested that these proteins might contain bioactive peptides that possess hypocholesterolemic and antioxidant activities that ameliorate sperm damage. Thornback ray muscle hydrolysate was investigated, as well as the undigested muscle, to test their hypolipidemic, antioxidative and fertility effects in rats fed with a high-cholesterol diet.![]()

Abstract
Objectives To evaluate different laboratory assessments of oxidative stress (OS) in semen and identify a cost-efficient and highly sensitive instrument capable of providing a comprehensive measure of OS in a clinical setting, as early intervention and an accurate diagnostic test are important because they help maintain a balance of free radicals and antioxidants; otherwise, excessive OS could lead to sperm damage and result in male infertility. Materials and methods A systematic literature search was performed through a MedLine database search using the keywords ‘semen’ AND ‘oxygen reduction potential’. We also reviewed the references of retrieved articles to search for other potentially relevant research articles and additional book chapters discussing laboratory assessments for OS, ranging from 1994 to 2017. A total of 29 articles and book chapters involving OS-related laboratory assays were included. We excluded animal studies and articles written in languages other than English. Results Direct laboratory techniques include: chemiluminescence, nitro blue tetrazolium, cytochrome C reduction test, fluorescein probe, electron spin resonance and oxidation–reduction potential (ORP). Indirect laboratory techniques include: measurement of Endtz test, lipid peroxidation, chemokines, antioxidants/micronutrients/vitamins, ascorbate, total antioxidant capacity, or DNA damage. Each of these laboratory techniques has its advantages and disadvantages. Conclusion Traditional OS laboratory assessments have their limitations. Amongst the prevalent laboratory techniques, ORP is novel and better option as it can be easily used in a clinical setting to provide a comprehensive review of OS. However, more studies are needed to evaluate its reproducibility across various laboratory centres.

Abstract
Objectives To review the literature and provide an updated summary on the role of reactive oxygen species (ROS) in male infertility. Methods A review of PubMed, Cochrane review, and Web of Science databases for full-text English-language articles published between 1943 and 2017 was performed, focusing on the aetiology of ROS, physiological role of ROS on spermatic function, pathological role of ROS in infertility, evaluation of ROS, and role of antioxidants in oxidative stress. Results ROS play a role in spermatic function and fertilisation. The literature describes both a physiological and a pathological role of ROS in fertility. A delicate balance between ROS necessary for physiological activity and antioxidants to protect from cellular oxidative injury is essential for fertility. Conclusion Although elevated levels of ROS are implicated as a cause of infertility, there is no consensus on selecting patients to test for ROS, which test to perform, or if treatment for ROS can have a positive impact on infertility rates and pregnancy.

Abstract
Male infertility affects men worldwide. Oxidative stress (OS), characterized by an overabundance of reactive oxygen species (ROS) or a deficiency of antioxidants, is one of the major causes of male infertility. OS causes damage at the molecular level, which impairs lipids, proteins, and DNA. The cyclic cascade of redox reactions weakens sperm function which leads to poor semen parameters and eventual sterility. There is a need for advanced diagnostic tests that can quickly and accurately detect OS. Most commonly used assays can only measure single constituents of OS. However, the MiOXSYS System introduces a new strategy to detect OS by measuring the oxidation-reduction potential (ORP)--a direct evaluation of the redox balance between ROS and antioxidants. The MiOXSYS System has shown promise as a diagnostic tool in the evaluation of male infertility. This review explores the concept of ORP, details the principle of the MiOXSYS System, and summarizes the findings in clinical studies that support ORP measurement in semen.
