Article In Vivo Antioxidant and Anti-Inflammatory Effects of Myrtus Communis Against Ionizing Radiation-Induced Gastrointestinal Injury: Trod-Grog Study(Kare Publishing, 2025) Kilic, Melisa Bagci; Varan, Melike Pekyurek; Atasoy, Ozum; Ozyilmaz, Nagehan; Pazarbasi, Seren Ede; Ertas, Busra; Atasoy, Beste Melek; Ercan, FerihaOBJECTIVE: This study aimed to investigate the in vivo radioprotective effects of Myrtus communis (MC) on the gastrointestinal system. METHODS: A total of 30 female rats were divided into four groups: i) Control; ii) irradiation (IR) only; iii) MC-pretreated; and iv) MC-treated. The rats received oral MC extract (100 mg/kg/day) for 4 days before exposure to 10 Gy IR or continued until sacrifice. On the fourth day of IR exposure, the rats were sacrificed, and histopathological and biochemical analyses were performed on the ileum, pancreas, and liver tissues. RESULTS: Malondialdehyde and myeloperoxidase levels decreased in both MC-treated groups, while glutathione levels and Na+-K+-ATPase activity increased (p<0.01), with significant histopathological improvements compared to the IR-only group. CONCLUSION: The results of this study demonstrate that MC significantly decreases ionizing radiation-induced oxidative and inflammatory damage in the gastrointestinal systems of rats. Therefore, it may be regarded as a new candidate with radioprotective potential for future clinical application.Article Citation - WoS: 3Citation - Scopus: 3Unraveling Hepatic Consequences of Intrauterine Growth Restriction and Catch-Up Growth: Insights From Histological, Biochemical and Metabolomic in Rats(Univ Basque Country Upv-Ehu Press, 2025) Esrefoglu, Mukaddes; Selek, Sahabettin; Koktasoglu, Fatmanur; Bayindir, Nihan; Hekimoglu, Emine-Rumeysa; Kirmizikan, Seda; Bekiroglu, SomerIntrauterine growth restriction (IUGR) is increasingly recognized as a significant risk factor for metabolic disorders in adulthood. Employing a multi-faceted approach encompassing histopathological, immunohistochemical, biochemical, Western-blotting, and metabolomics analyses, this study aimed to elucidate potential metabolite markers of IUGR, and catch-up growth-related metabolic disturbances and the underlying metabolic pathways implicated in IUGR pathogenesis. This study cohort comprised 54 male siblings from 20 Sprague-Dawley female young rats. On the 19th day of gestation, half of the pregnant rats underwent bilateral uterine artery ligation, while the remaining half underwent a simulated surgical intervention involving solely peritoneal incisions. Blood and liver samples were collected from the pups after attaining catch-up growth at the postnatal weeks 2, 4, and 8. IUGR rats exhibited a spectrum of changes including histological abnormalities, altered apoptosis rates, oxidative stress markers, and mitochondrial energy metabolism. Metabolomic analysis revealed dysregulation in multiple metabolic pathways encompassing galactose, propanoate, glycerolipid, cysteine, methionine, and tyrosine metabolism, among others. Notably, disturbances were observed in butanoate, glutathione metabolism, as well as glycolysis/gluconeogenesis. Our metabolomics analysis provides insights into the potential disease susceptibility of individuals born with IUGR, including obesity, diabetes, heart failure, cancer, mental retardation, kidney and liver diseases, and cataracts. These findings underscore the intricate interplay between intrauterine conditions and long-term metabolic health outcomes, highlighting the need for further investigation into preventive and therapeutic strategies aimed at mitigating the risk of metabolic diseases in individuals with a history of IUGR.Conference Object The Effect of Myrtus Communis Extract on High Fat Diet Induced Liver Damage in Rats(Wiley, 2025) Sucu, Gizem; Kabatas, Gul Sinemcan; Ertas, Busra; Sen, Ali; Sener, Goksel; Ercan, Feriha; Akakin, DilekArticle Citation - WoS: 6Citation - Scopus: 5The Effect of Melatonin on Glycoprotein Levels and Oxidative Liver Injury in Experimental Diabetes(Wiley, 2023) Ertik, Onur; Sener, Goksel; Yanardag, RefiyeIn this present study, the duration of melatonin (Mel) administered to diabetic rats was prolonged so as to examine its effects on the biochemical liver parameters of diabetic rats. In the experiment, Male Sprague Dawley rats were divided randomly into five groups; the control, diabetic + Mel, diabetic, diabetic + insulin, and diabetic + Mel + insulin. Diabetes mellitus was induced by administration of a single dose of streptozotocin (60 mg/kg) intraperitoneally and rats were given vehicle as a solvent for Mel every day for 12 weeks. In the diabetic + Mel group, diabetic rats were administered Mel (10 mg/kg/day) for 12 weeks to treat diabetes. The diabetic + insulin group were diabetic rats given insulin (6 U/kg) subcutaneously for 12 weeks. The diabetic + Mel + insulin rats received insulin and Mel at the same dose and time. At the end of the experiment, the animals were decapitated and liver tissues were taken. The protective effect of Mel on liver tissue of diabetic rats was investigated, total antioxidant status, total oxidant status, reactive oxygen species, oxidative stress index, adenosine deaminase, xanthine oxidase, paraoxonase 1, sodium/potassium ATPase, myeloperoxidase, gamma-glutamyl transferase, sorbitol dehydrogenase, tumor necrosis factor-alpha, homocysteine, nitric oxide, glucose-6-phosphate dehydrogenase, and glycoprotein levels were determined in liver tissues. Treatment with Mel and/or insulin has been found to have a protective effect on biochemical parameters. The results showed that administration of Mel to diabetic rats prevented the distortion of the studied biochemical parameters of liver tissues.
