Kahn, MD Long-term Overall Goal: To determine the mechanisms by which reduction of ChREBP in adipocytes causes systemic insulin resistance and impaired glucose transport in adipocytes. Background: Carbohydrate Response Element Binding Protein (ChREBP) is the major transcription factor regulating de novo lipogenesis (DNL, fatty acid synthesis from glucose) in adipocytes. We showed that adipose-selective ChREBP KO (AdChREBP KO) causes systemic insulin resistance and impairs insulin-stimulated glucose transport in adipocytes. In humans, expression of ChREBP and genes regulating DNL in adipose tissue correlate highly with insulin sensitivity measured by clamp.
