| Abstract | Objectives: Since Selenium (Se) forms part of glutathione peroxidase (GPx), which appears to have a dual role in Metabolic Syndrome (MS), this study evaluates the implication of Se in the transmission of this pathology to the progeny. Methods: Se body distribution, glucose, triglycerides, cholesterol, insulin and metabolic hormones [glucagon, leptin, gastric inhibitory polypeptide (GIP), and triiodothyronine (T3)], growth factors, receptor activator of nuclear factor kappa-B ligand (RANK-L) and osteopontin, as well as oxidative hepatic balance in the offspring of dams exposed to a fructose-rich diet (65%) with normal Se content (0.01 ppm) during gestation and lactation, were measured according to sex. Results: Fructose pups had lower body weight; however, male pups had a lower body mass index and growth indicators in serum. Fructose pups, especially females, had lower levels of serum insulin and HOMA-IR. With regard to Se homeostasis, fructose pups presented a depletion of Se in heart and muscle, and repletion in kidneys, pancreas and thyroid, although only female pups showed a repletion of Se in the liver. Fructose pups presented lower superoxide dismutase activity and only female fructose pups had higher GPx activity, which provoked hepatic oxidation. Conclusions: Se balance and Se tissue deposits in MS pups during lactation are altered by gender. This difference is focused on hepatic Se deposits that affect GPx activity, which could be related to a disruption in the insulin-signaling cascade in females. Furthermore, although female fructose pups had greater metabolic disorders, only the males’ growth and development were affected. Particularly relevant is the depletion of Se found in the heart of fructose pups, as this element is essential for correct heart function. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
