The Lira Lab has a paper published in the journal Scientific Reports demonstrating for the first time that deficient skeletal and cardiac muscle autophagy leads to maladaptive adaptations to exercise training in the hearts of obese, pre-diabetic mice. Interestingly, the maladaptive hearts of these mice produce high levels of FGF21, which elevates circulating FGF21 leading to a thermogenic phenotype in brown adipose tissue and improvement of whole-body glucose handling. The paper is freely available here.
