In utero hyperglycemia has consequences on future outcomes in the offsprings. We had earlier shown that in utero hyperglycemia impacts proteoglycans/glycosaminoglycans, one of the key molecules involved in brain development. Hypothalamic HSPGs such as syndecan-1 and syndecan-3 are well known for their involvement in feeding behavior. Therefore, studies were carried out to determine the effect of maternal hyperglycemia on the expression of HSPGs in the hypothalamus of offspring brain. Results revealed increased protein abundance of Syndecan-1 and -3 as well as glypican-1 in postnatal adults from hyperglycemic mothers. This was associated with increased hyperphagia and increased expression of Neuropeptide Y. These results indicate the likely consequences on offsprings exposed to in utero hyperglycemia on its growth.
