Peptide-Based Regulation of Metabolism as Related to Obesity.

Currently there are few, if any, approved and effective medicines for the attenuation of obesity, diabetes, and insulin resistance. This commentary addresses a communication describing the effect on glucose dynamics and obesity of a peptide monoclonal antibody for fibroblast growth factor (FGF) receptor 1c isoform (FGFR1c). The general lack of suitable, effective drugs is discussed, as is the treatment potential of FGF family receptors. The FGFR1c monoclonal antibody developed by the authors lowers body weight gain, blood glucose, and adipose tissue weight. It also enhances glucose uptake by fat cells [white adipose tissue (WAT) and 3T3-L1]. The robust weight loss, fat loss, and lower blood glucose were attributed to an observed potential futile cycle of continuous lipogenesis and lipolysis and adenosine triphosphate use in WAT.
