According to the fetal programming hypothesis, impaired intrauterine development results in insulin resistance and associated metabolic disturbances. Recently, we reported increased body fat, a forerunner of insulin resistance, in the pups of mineral-restricted rat dams. To identify the causative mineral(s), the effect of magnesium restriction was assessed.(More)
Epidemiological evidence suggests that some adult diseases like insulin resistance syndrome and diseases associated with it originate in fetal life. The role of maternal macronutrient malnutrition but not of micronutrients in the fetal origin of adult disease is well studied. We hypothesise that chronic maternal vitamin restriction predisposes the offspring(More)
DNA methylation is crucial for gene regulation and maintenance of genomic stability. Rat has been a key model system in understanding mammalian systemic physiology, however detailed rat methylome remains uncharacterized till date. Here, we present the first high resolution methylome of rat liver generated using Methylated DNA immunoprecipitation and high(More)
Maternal vitamin deficiencies are associated with low birth weight and increased perinatal morbidity and mortality. We hypothesize that maternal folate and/or vitamin B(12) restrictions alter body composition and fat metabolism in the offspring. Female weaning Wistar rats received ad libitum for 12 weeks a control diet (American Institute of Nutrition-76A)(More)
The Marfan syndrome (MFS) is a connective tissue disorder manifested by variable and pleiotropic features in the skeletal, ocular, and cardiovascular systems. The average life span in MFS is about 35 years. A group with much more severe cardiovascular disease and a mean life span of approximately 1 year also exists. We refer to this latter group as(More)
Apoptosis Associated Tyrosine Kinase (AATYK), a novel protein recently isolated from differentiating 32D mouse myeloid cells, contains a putative tyrosine kinase domain and several binding motifs for src homology 2 (SH-2) and src homology 3 (SH-3) domain containing proteins. We observed that AATYK is expressed in different regions of the brain. Although it(More)
OBJECTIVE We investigated the long-term effects of maternal/postnatal magnesium (Mg) restriction on adiposity, glucose tolerance, and insulin secretion in the offspring and the probable biochemical mechanisms associated with them. METHODS AND PROCEDURES Female weanling Wistar/NIN (WNIN) rats received a control diet or 70% Mg-restricted (MgR) diet for 9(More)
OBJECTIVE We demonstrated previously that chronic maternal micronutrient restriction altered the body composition in rat offspring and may predispose offspring to adult-onset diseases. Chromium (Cr) regulates glucose and fat metabolism. The objective of this study is to determine the long-term effects of maternal Cr restriction on adipose tissue development(More)
BACKGROUND Maternal undernutrition is hypothesized to predispose the offspring to disease in adult life. The relevance of maternal macronutrient deficiency has been well studied but not that of micronutrients. OBJECTIVE To assess the effect of maternal dietary mineral restriction per se on oral glucose tolerance (OGT), insulin resistance (IR) and fat(More)
Maternal undernutrition increases the risk of adult chronic diseases, such as obesity and type 2 diabetes. This study evaluated the effect of maternal zinc restriction in predisposing the offspring to adiposity and altered insulin response in later life. Seventy-day-old female Wistar/NIN rats received a control (ZnC) or zinc-restricted (ZnR) diet for 2(More)
