Spexin ameliorates skeletal muscle insulin resistance through activation of GAL2 receptor.

Skeletal muscle is a principal tissue involved in energy expenditure and glucose metabolism. Although the results of our and other studies show that spexin could decrease food intake and obesity, the specific metabolic effect of spexin on glucose metabolism of skeletal muscle is still unclear. The aim of this study is to investigate whether spexin might mitigate obesity-induced insulin resistance in skeletal muscles and to explore its underlying mechanisms.

Loss of chemerin triggers bone remodeling in vivo and in vitro.

Objective: It was reported that chemerin as an adipocyte-secreted protein could regulate bone resorption and bone formation. However, the specific molecular and gene mechanism of the chemerin role is unclear. The aim of this study is to evaluate the role of chemerin in bone metabolism.

Development of metabolic dysfunction in mice lacking chemerin.

Chemerin, an adipocyte-secreted adipokine, is hypothesized to participate in energy homeostasis and glucoregulation. However, the physiologic effect of endogenous chemerin on glucose metabolism is unclear. The present studies tested the hypotheses that chemerin deficiency alters whole-body glucose homeostasis following switches to high-fat diet.
