High-Dose Leptin Reversed Severe Genetic Obesity in Two Patients
Personalized recombinant leptin treatment helped reverse severe, early-onset obesity in two children carrying rare antagonistic leptin genetic variants, a study showed. In the double case report, two unrelated children — a 14-year-old boy and a 2-year-old girl — presented with what appeared to be leptin dysfunction, marked by intense hyperphagia, lack of satiety, and severe […]
Fat-secreted molecule lowers response to common cancer treatment

The findings, published online Aug. 13 in npj Breast Cancer, could help explain […]
