Western Blot: Fatty Acid Synthase/FASN Antibody [NB400-114]

Western Blot: Fatty Acid Synthase/FASN Antibody [NB400-114] - Expression of Fatty Acid Synthase in chicken hypothalamus. A: total RNA (1 ug) isolated from different tissues (brain, hypothalamus, liver and muscle) was subjected to RT-PCR using specific primers for chicken Fatty Acid Synthase (GenBank accession JO4485) or ribosomal 18S as a control (GenBank accession AF173612) B: tissue lysates (brain, hypothalmus, liver and muscle) were subjected to Western blot as described in MATERIALS AND METHODS. Blots were incubated with anti-Fatty Acid Synthase antibody and revealed by enhanced chemiluminescence.

Background: Fatty Acid Synthase/FASN

Fatty acid synthetase (FASN) is a key player of fatty acid biosynthetic pathway and it catalyzes formation of long-chain fatty acids from acetyl-CoA, malonyl-CoA and NADPH (de novo lipid synthesis). Localized in cytoplasm and melanosomes, FASN is expressed at low level in normal adult tissues; however, it is significantly upregulated in cancer cells. The FASN expression is regulated by growth factors/growth factor receptors (EGFR and HER2) and steroid hormone /steroid hormone receptors (ER, AR and progesterone receptor). Downstream of the receptors, PI3K-AKT and MAPK signaling mediate FASN expression through SREBP-1c. FASN expression is also controlled by p53 family proteins and SPOT14, lipogenesis-related nuclear protein generally overexpressed in breast cancer. Extracellular stresses including hypoxia and low pH also induce the FASN expression in cancer cells and USP2a stabilises FASN alongwith promotion of its mTOR-dependent selective translational induction. FASN activation provides rapidly proliferating tumor cells sufficient amount of lipids for membrane biogenesis and confers growth/survival advantage possibly acting as a metabolic oncogene. Because FASN-inhibitors are selectively toxic to tumor cells, it has emerged as an attractive target for cancer.
