promote structural growth, while the primary action of insulin is to regulate nutrient utilization in response to a meal. Despite these primary actions, IGF1 and insulin demonstrate important crossover effects on growth and metabolism ( Messina 2010

Introduction The totality of biochemical reactions that a cell requires to grow, survive and respond to external stimuli is known as metabolism. These processes are classified into two interdependent groups. Catabolism is the set of reactions that

repression of gene expression ( De Ruijter et al . 2003 ). Recent studies suggest that HDACs play a role in the regulation of skeletal muscle metabolism. Dietary supplementation of butyrate prevented diet-induced insulin resistance in mice, and this effect

NAD + as a redox cofactor and signalling molecule The vital role of NAD + in redox metabolism was first described in 1906 by Arthur Harden as being a required cofactor for alcohol fermentation ( Harden & Young 1906 ). It has since been well

order to sustain elevated protein synthesis required for neoplastic growth, malignant cells must adjust their energy metabolism. MTOR is a key regulator of translation ( Sonenberg & Hinnebusch 2009 ). AMP-activated protein kinase ( AMPK ) acts as an

Introduction Skeletal muscles are specialised contractile tissues that control posture and physical activity while having an important role in energy metabolism. Their function is dependent on the composition and strength of fibre types that require

only respond to elevated glucose, avoiding the inappropriate and damaging release of insulin. Following transport into the cytosol, the sugar stimulates oxidative and glycolytic metabolism, leading to ATP generation in the mitochondria at the expense of
