In rats, the hyperphagia induced by a 48 h fast, or a hypoglycemic hyperinsulinemic clamp, or uncontrolled diabetes, was completely s...

To read the full abstract: J Clin Invest 2020;130(4):2001–16.In this study, Perry et al used their well-established animal model of fasted rats to unravel how feeding induces hyperthermia and energy expenditure.They showed that intracerebroventricular injection of leptin normalized fasting induced low plasma epinephrine and norepinephrine levels and body temperat...

By acting via an unknown tyrosine kinase, isthmin-1 (ISM1) ameliorates metabolic disturbances associated wit...
