Modulation of Some Insulin Signaling Genes Due to Prenatal Rice Consumption
نویسندگان
چکیده مقاله:
Objective: A clinically observable metabolic disorder often takes its root from modulation of transcriptional factors which in turn are responsible for perturbed protein expressions and their sequelae. Perinatal perturbations due to chronic prenatal exposure to a certain type of rice could predispose parents exposed to such ‘insult’ and their subsequent offsprings to metabolic diseases. Materials and Methods: We investigated the effect of chronic prenatal exposure to different types of rice (in context of a balanced normal diet and a high-fat diet) on some insulin signaling genes using nulliparous Sprague Dawley rats. The rats were exposed to various predetermined rice diets for 90 days. After returning them to standard chow, they were mated with male rats raised on standard chow. The resulting pups (F1) and dams were sacrificed and their tissues were examined for modulation of genes related to insulin signaling. Results: Our results show that dams fed with white rice in context of standard diet modulated MAPK1, MAFA1 and SLC2A2. Also, germinated brown rice prevented dysregulation of MAPK1, and SLC2A2 in both dams and pups exposed to this diet in the context of a high-fat diet. In general, germinated brown rice retarded dysregulations due to high-fat diet exposure while white rice enhanced the dysregulatory effects of high-fat diet. Conclusion: We conclude that chronic prenatal exposure to a certain type of rice, could be a factor to modulation of some genes related to insulin signaling pathways and that these modulation could be inherited by at least one generation of offsprings.

15 صفحه اولPredisposition to insulin resistance and obesity due to staple consumption of rice: Amylose content versus germination status
Type 2 diabetes is a metabolic disorder with established, well-defined precursors. Obesity and insulin resistance are amongst most important factors in predisposition to diabetes. Rice is a staple for about half the global population and its consumption has been strongly linked with diabetogenesis. We assert that tackling the prevalence of predisposing factors by modifying certain rice cultivar...
متن کاملPrenatal Methylmercury Exposure through Rice Consumption in Rural China
Background: Methylmercury is one of the most toxic forms of mercury, which severely afflicts the developing fetus. Methylmercury exposure occurs not only through fish consumption but also through rice consumption. However, rice does not contain the same beneficial micronutrients that fish/shellfish has. Therefore, prenatal methylmercury exposure through maternal rice consumption may potentially...

متن کاملDrosophila germ-line modulation of insulin signaling and lifespan.
Ablation of germ-line precursor cells in Caenorhabditis elegans extends lifespan by activating DAF-16, a forkhead transcription factor (FOXO) repressed by insulin/insulin-like growth factor (IGF) signaling (IIS). Signals from the gonad might thus regulate whole-organism aging by modulating IIS. To date, the details of this systemic regulation of aging by the reproductive system are not understo...
