Article The Therapeutic Role of Ginseng in Promoting Hippocampal Neurogenesis and Ameliorating Cognitive Function Following Whole Brain Radiotherapy in Rats(Springer/Plenum Publishers, 2025) Sahin, Sevim; Bayindir, Nihan; Ertas, Busra; Ceylan, Cemile; Elibol, Birsen; Ozkan, Alper; Sener, GokselWhole-brain radiotherapy (WBRT) is a prevalent technique for managing multiple intracranial metastases, however, the cognitive damage in long-term survivors due to WBTR is a critical concern that impacts patients' quality of life. Panax ginseng, a bioactive compound recognized for its neuroprotective benefits, also enhances cognitive functions, including memory and learning. This study aims to examine the potential protective effects of Panax ginseng supplementation on cognitive dysfunction and the levels of neurogenesis-related proteins in the hippocampus of rats that underwent WBRT, which was delivered as 3 fractions of 6 Gy (total dose 18 Gy) using a linear accelerator. Thirty-six male Sprague-Dawley rats were divided into three groups: radiation, ginseng treatment, and control. After 60 days of Panax ginseng administration (100 mg/kg), behavior tests (Morris water maze and novel object recognition) were performed, followed by western blot analysis of the hippocampus. Results indicated that Panax ginseng supplementation ameliorated radiation-induced cognitive impairments. Additionally, western blot analyses revealed that Panax ginseng promoted neuronal recovery and neuroplasticity processes in the hippocampus, simultaneously exhibiting a neuroprotective mechanism by reducing apoptosis and neurotoxicity markers. Panax ginseng ameliorates cognitive dysfunction after WBRT by enhancing neurogenesis and diminishing cell death in the hippocampus.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.Article Unraveling the Persistent Renal Impact of Intrauterine Growth Restriction and Catch-Up Growth: Integrating Morphological Insights with Metabolomic Profiling(Springer, 2025) Esrefoglu, Mukaddes; Koktasoglu, Fatmanur; Bayindir, Nihan; Cimen, Fatma Bedia Karakaya; Kirmizikan, Seda; Hekimoglu, Emine Rumeysa; Selek, SahabettinThe study aimed to investigate the long-term effects of IUGR and consequent catch-up growth on metabolic health by using a comprehensive approach that included histopathological, immunohistochemical, biochemical, and metabolomics analyses. Sprague-Dawley pregnant rats either undergo bilateral uterine artery ligation or a sham surgery on the 19th day of gestation. The offspring reached catch-up growth, kidney samples were collected at postnatal weeks 2, 4, and 8 for analysis. IUGR rats exhibited a spectrum of changes including reduced glomeruli number, proliferating cell number, altered oxidative stress markers, various enzymes involved in Krebs cycle, mitochondrial dynamics, and energy metabolism. Examination of the 8-week-old cohort identified a broader spectrum of metabolic alterations, notably in the biosynthesis of phenylalanine, tyrosine, and tryptophan, phenylalanine, tyrosine, glyoxylate, dicarboxylate, pyruvate, alanine, aspartate, and glutamate metabolism, glycolysis/gluconeogenesis and citrate (TCA) cycle. Our metabolomics analysis provides insights into the potential disease susceptibility of individuals born with IUGR, including obesity, diabetes, hypertriglyceridemia, cardiovascular diseases, and mental retardation. 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 to mitigate the risk of metabolic diseases in individuals with a history of IUGR.
