A total of 42 female Wistar rats (12-weeks-old) were used in the study. Six of these rats were allocated as donors, and the remaining 36 rats were randomly distributed into six groups (n = 6 per group). Group 1 received no treatment. On the 1st and 7th days, 75 mg/kg of CP was administered intraperitoneally to Groups 4, 5, and 6. On day 1, PRP was administered intraovarianly to Groups 2 and 5, while ACRS was administered intraovarianly to Groups 3 and 6. Additionally, PRP and ACRS were administered intraperitoneally to the respective groups on 7th and 14th days.The study was terminated at the end of the 31st day. Brain tissue and blood samples were collected for biochemical analyses and ovarian tissue samples were collected for histomorphological examinations. Morphological analysis using Hematoxylin–Eosin (HE) staining and immunohistochemical evaluation for AMH, α-SMA, and IL-1β were conducted on the ovaries. Proinflammatory cytokines and insulin levels were measured using ELISA test kits. TAS/TOS levels were assessed using Relassay Diagnostic kits. Biochemical parameters and mineral levels were measured using autoanalyzer. Histopathological evaluation revealed that follicular degeneration, congestion, hemorrhage, edema, and inflammatory cell infiltration, as well as the number of atretic follicles and IL-1β immunoreactivity, were observed at the highest levels in the CP group (Group 4). In contrast, the numbers of primordial, primary, secondary, and tertiary follicles, along with AMH and α-SMA immunoreactivity levels, were found to be the lowest in this group.

However, it’s still unclear whether this pathway plays a certain role in hypertension. In this study, aortic morphology and function in spontaneously hypertensive rats (SHR) were comprehensively evaluated using Wistar-Kyoto rats (WKY) as controls. Results indicated that the aorta of SHRs have distinct changes in pathological structure. Furthermore, the proliferative activity of vascular smooth muscle cells (VSMCs) was enhanced, with vascular fibrosis being aggravated. Immunohistochemical analysis revealed that SHRs exhibited high expression of Yes-Associated Protein (YAP). Western Blot analysis showed that cytoplasmic YAP and TAZ expression decreased in hypertensive rats, indicating that YAP/TAZ nuclear transfer increased and Hippo/YAP signaling pathway had been activated. The cell function experiments of VSMCs extracted from rat aorta showed that the cell viability and proliferation ability of VSMCs in SHRs were enhanced, the expression of Fibronectin and collagen I was increased, and vascular fibrosis was aggravated. siRNA-YAP (si-YAP) can reverse the above phenomenon in VSMCs. Knockdown of YAP can inhibit Foxm1 expression. As an inhibitor of large tumor suppressor kinases LAST1/2, GA-107 can inhibit the phosphorylation level of YAP, increase blood pressure, aggravate aortic pathomorphological changes, promote VSMCs proliferation and vascular fibrosis, and thus aggravate hypertension symptoms in SHRs. However, these effects of GA-107 can be antagonized by inhibiting Foxm1 with thiosulfathiazole (Thio).

Following the treatment, blood samples were obtained for the assessment of biochemical parameters, and the cardiac and pulmonary tissues were removed for the measurement of oxidative stress and inflammatory cytokines and histological alterations. 5-FU elevated lipid profiles (triglyceride, low-density lipoprotein (LDL), and cholesterol), glucose serum levels, and myocardial injury markers (CK-MB and LDH), malondialdehyde (MDA), interleukin‐6 (IL-6) and tumor necrosis factor alpha (TNF-α) expression. Additionally, the histopathological analysis of 5-FU revealed dystrophic calcification (DC) in the cardiac tissues and neutrophil infiltration in the lung tissues. However, the administration of OLE reduced lipid profiles, glucose, lactate dehydrogenase (LDH), creatine kinase-myocardial band (CK-MB) levels and inflammation, improved antioxidant capacity, and pathological alterations. It seems that OLE exerts cardio-pulmonary protective effects against 5-FU toxicity through the decrease of oxidative stress and inflammatory cytokines.</p></div>","PeriodicalId":650,"journal":{"name":"Journal of Molecular Histology","volume":"56 3","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143925681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we aimed to investigate the potential protective effects of liraglutide, a Glucagon-like peptide-1 (GLP-1) analogue against CIS-induced peripheral neuropathy. For this purpose, female Sprague Dawley rats (<i>n</i> = 32) were randomly allocated into 4 groups: control, CIS, CIS + liraglutide (once weekly) and CIS + liraglutide (daily). Neuropathic pain was induced by CIS 3 mg/kg/week for 5 weeks. The potential effects of liraglutide were investigated by behavior tests (von Frey, tail flick and footprint analysis), biochemical analysis and histopathological analyses of sciatic nerves and dorsal root ganglions. In the von Frey and tail flick tests, liraglutide demonstrated anti-neuropathic effects. Liraglutide also ameliorated motor coordination which was impaired by CIS. Liraglutide was shown to have beneficial effects against CIS-induced peripheral neuropathy by parameters demonstrating reduction of histopathological damage (stained by toluidine blue) of the sciatic nerves and dorsal root ganglions, suppression of oxidative stress parameters (SOD, CAT and GPx), and inflammatory load (NO, IL-6 and IL-10). Weekly dosing regimen was more effective than daily administration of liraglutide in this study. As a result, liraglutide seems to be the candidate agent for the effective treatment of CIS-induced peripheral neuropathy.</p></div>","PeriodicalId":650,"journal":{"name":"Journal of Molecular Histology","volume":"56 3","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143925680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
