Background: Haploinsufficiency of the GATA3 gene located on chromosome 10p15, is well-recognised as the cause of hypoparathyroidism, sensorineural deafness and renal dysgenesis; the HDR syndrome. A number of abnormalities within the GATA3 gene have been identified, with varying phenotypic characteristics. GATA3 is associated with other abnormalities including, abnormalities of Mullerian structures, hypomagnesia, hemimegalenencephaly and diabetes mell...

Background: Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of diseases starting with pathological accumulation of intrahepatocellular triglyceride (TG) (i.e. steatosis), which can progress to steatohepatitis (NASH) and cirrhosis. Insulin resistance is often associated with the development of steatosis and disease progression however, the underlying mechanisms for this are poorly defined. A major challenge in modelling human NAFLD disease progression is the la...

Introduction: Increased hepatic de novo lipogenesis (DNL) is often associated with greater intrahepatic triglyceride (IHTG) content and/or decreased insulin sensitivity; however, the contribution of DNL to each has not been fully elucidated. Therefore, the present work determined if increased DNL, achieved via adoption of an isocaloric high-sugar diet, resulted in concomitant increases in IHTG content and/or decreases in insulin sensitivity.Methods: Sixt...

Background: Fasting hyperglycaemia and hypertriglyceridemia are characteristic of insulin resistance (IR), type 2 diabetes, and non-alcoholic fatty liver disease, but the underlying mechanisms remain unclear. Rodent work has suggested this is due to selective hepatic IR; defined by increased hepatic gluconeogenesis (GNG) and de novo lipogenesis (DNL). The aim of this study was to determine if signatures of selective hepatic IR were associated with hyp...
