Docosapentaenoic acid (22:5n-3) down-regulates the expression of genes involved in fat synthesis in liver cells.

Previous studies have shown that Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) exhibit triacylglycerol (TAG) lowering effect in vitro and in vivo by down-regulating the Sterol Regulating Element Binding Protein (SREBP-1c) and reducing the expression levels of lipogenic genes. However, there is no evidence on the effect of Docosapentaenoic Acid (DPA) on SREBP-1c expression levels. DPA is a long chain n-3 fatty acid present in our diet through fish, red meat and milk of ruminant animals.

The measurement of GLUT4 translocation in 3T3-L1 adipocytes.

Type 2 diabetes (T2D) is one of the fastest growing threats to human health in westernised and developing countries and is associated with central obesity, atherosclerosis, dyslipidaemia, hyperinsulinaemia and hypertension. Insulin resistance, defined as a diminished response to ordinary levels of circulating insulin in one or more peripheral tissues, is an integral feature of T2D pathophysiology. This includes an impairment of insulin to inhibit hepatic glucose output and to stimulate glucose disposal into muscle and fat.

Targeted disruption of the basic Krüppel-like factor gene (Klf3) reveals a role in adipogenesis.

Krüppel-like factors (KLFs) recognize CACCC and GC-rich sequences in gene regulatory elements. Here, we describe the disruption of the murine basic Krüppel-like factor gene (Bklf or Klf3). Klf3 knockout mice have less white adipose tissue, and their fat pads contain smaller and fewer cells.
