Maternal obesity characterized by gestational diabetes increases the susceptibility of rat offspring to hepatic steatosis via a disrupted liver metabolome

Abstract: Key pointsr Gestational diabetes mellitus is a common complication of pregnancy, but its effects on the offspring are poorly understood.r We developed a rat model of diet-induced gestational diabetes mellitus that recapitulates many of the clinical features of the disease, including excessive gestational weight gain, glucose intolerance, hyperinsulinaemia and mild hyperglycaemia.r Compared to the offspring of lean dams, exposure to gestational diabetes mellitus during the prenatal period resulted in obesity, h… Show more

“…Rats were given ad libitum access to food and water and were housed two per cage. As described previously [25], GDM was induced in female Sprague-Dawley rats using a high-fat and sucrose diet (HFS; 45% fat, 4.73 kcal/gm, Research Diets D12451; New Brunswick, NJ, USA) for 6 weeks prior mating, throughout gestation and lactation, while lean control dams were fed a low-fat diet (LF, 10% fat, 3.85 kcal/gm, Research Diets D12450B). All females were mated with lean males.…”

“…The dams experienced increased weight gain during pregnancy and starting mid-gestation developed hyperinsulinemia and moderate hyperglycemia (Table 1). This model mimics clinical symptoms of GDM seen in mothers as well as their offspring that developed obesity and insulin resistance [2, 25]. Litters were randomly reduced to eight pups in order to avoid competition for food.…”

“…How these observations relate to muscle insulin resistance and mitochondrial function, remain largely unknown at present; however, diacylglycerols can be converted to phospholipids through CTP:phosphoethanolamine cytidylyltransferase (Singh et al 2012) and disruption of this pathway has been implicated in diacylglycerol accumulation, hepatic steatosis, and insulin resistance in rodents exposed to gestational diabetes during fetal development (Pereira et al 2015). In addition, in vitro studies suggest that arachidonic acid containing diacylglycerols are more potent activators of down-stream For personal use only.…”
