: The consumption of diets with high fat, salt, and sugar content has been associated with increasing the risk of developing a range of pathologies, including cardiovascular disease, obesity, and diabetes. Furthermore, there is growing evidence to suggest a relationship between variation in the nutritional environment and pancreatic dysregulation, which may be a consequence of oxidative stress. This study aimed to examine the effects of a high-fat, high-carbohydrate (obesogenic) maternal diet during pregnancy and lactation on the metabolic health and pancreatic structure of rat offspring. : Pregnant rats were divided into two groups: one fed a standard diet and the other an obesogenic diet. After weaning, male pups from both groups were fed the same diet until they were 30 days old, which is when they were euthanized. : Metabolic and murinometric changes: Increased body weight and pancreas size, elevated blood glucose and cholesterol levels, and reduced glucose tolerance (which is indicative of the beginning of insulin resistance). Oxidative stress: Higher levels of oxidative damage markers and decreased antioxidants in the pancreas, suggesting a state of oxidative stress in this organ. Changes in pancreatic structure: Increased size and number of pancreatic islets and decreased size and number of pancreatic acini. : A maternal obesogenic diet induces metabolic alterations, increases oxidative stress, and causes changes in the structure of the pancreas in rat offspring, suggesting a higher risk of developing metabolic diseases such as type 2 diabetes in adulthood.
高脂肪、高盐和高糖饮食的摄入与一系列疾病的发病风险增加有关,包括心血管疾病、肥胖症和糖尿病。此外,越来越多的证据表明营养环境的变化与胰腺调节异常之间存在关联,这可能是氧化应激的结果。本研究旨在探讨孕期和哺乳期高脂、高碳水化合物(致肥胖)母体饮食对大鼠后代代谢健康和胰腺结构的影响。
一组喂食标准饮食,另一组喂食致肥胖饮食。断奶后,两组的雄性幼崽都喂食相同的饮食,直到30天大时安乐死。
体重和胰腺大小增加,血糖和胆固醇水平升高,葡萄糖耐量降低(这表明胰岛素抵抗开始)。
胰腺中氧化损伤标志物水平升高,抗氧化剂减少,表明该器官处于氧化应激状态。
胰岛大小和数量增加,胰腺腺泡大小和数量减少。
母体致肥胖饮食会导致大鼠后代代谢改变、氧化应激增加,并引起胰腺结构变化,这表明成年后患2型糖尿病等代谢疾病的风险更高。
