Obesity, Diabetes and Cancer: A Mechanistic Perspective
Journal Title: International Journal of Diabetology & Vascular Disease Research (IJDVR) - Year 2015, Vol 0, Issue 1
Abstract
Nearly 35% of adults and 20% of children in the United States are obese, defined as having a body mass index (BMI) ≥ 30kg/m2 . Obesity is an established risk factor for many cancers, and obesity-associated metabolicperturbations often manifest in Type 2 diabetes mellitus and/or the metabolic syndrome. As part of the growth-promoting, proinflammatory microenvironment of the obese and/or diabetic state, crosstalk between macrophages, adipocytes, and epithelial cells occurs via metabolically-regulated hormones, cytokines, and other mediators to enhance cancer risk and/or progression. This review synthesizes the evidence on key biological mechanisms underlying the associations between obesity, diabetes and cancer, with particular emphasis on enhancements in growth factor signaling, inflammation, and vascular integrity processes. These interrelated pathways represent mechanistic targets for disrupting the obesity-diabetes-cancer link, and several diabetes drugs, such as metformin and rosiglitazone, are being intensely studied for repurposing as cancer chemopreventive agents.
