Matching supply and demand: how does metabolism fine-tune signal transduction?

点击翻译按钮获取中文摘要

Insulin controls nutrient traffic and disrupting its actions are linked to many diseases: type 2 diabetes, cancer, heart disease. Here, I will test a novel hypothesis that our cells’ metabolic rate, defined by the balance between nutrient supply and energy expenditure, controls how cells respond to insulin. These metabolic regulatory nodes would play a major determinant of many essential functions linked to human health, and thus provide novel therapeutic targets for numerous diseases.
