عنوان انگلیسی Potential therapeutic effects of shrimp protein hydrolysates on NAFLD-induced infertility disorders: Insights into redox balance, heat shock protein expression, and chromatin compaction in male rats
چکیده انگلیسی مقاله Objective(s): Nonalcoholic fatty liver disease (NAFLD) is known to disrupt testicular anti-oxidant capacity, leading to oxidative stress (OS) that can negatively affect male fertility by damaging sperm DNA. Heat shock proteins (HSP70 and HSP90), in association with transitional proteins (TP1 and TP2), play crucial roles in protecting sperm DNA integrity in oxidative conditions. Whiteleg shrimp protein hydrolysates (HPs) exhibit anti-oxidant properties, prompting this study to explore the potential of HPs in ameliorating NAFLD-induced testicular damage. Materials and Methods: The study divided rats into four groups: control, a group subjected to a high-fat diet (HFD) to induce NAFLD without supplementation, and two HFD-induced NAFLD groups receiving HP doses (20 and 300 mg/kg). After 70 days, the testicular total anti-oxidant capacity (TAC), malondialdehyde (MDA), glutathione (GSH), glutathione disulfide (GSSG), HSP70-2a, HSP90 expression, and TP mRNA levels were assessed. Results: The results showed that HFD-induced NAFLD significantly increased GSH and MDA levels and disrupted the GSH/GSSG ratio (P<0.05) while also reducing HSP70-2a, HSP90, TP1, and TP2 expression (P<0.05). However, HP administration effectively restored testicular redox balance, reduced oxidative stress, and enhanced these protective proteins’ expression compared to HFD (P<0.05). Conclusion: NAFLD negatively affects the testicular redox system and HSP and TP expression, disrupting male fertility potential. In contrast, HP-treated rats showed a marked effect on NAFLD-induced damage by improving testicular anti-oxidant status and regulating the expression of HSPs and TP proteins. These findings suggest a potential therapeutic role for HP in safeguarding male fertility against the damaging effects of NAFLD.
