Postweaning low-calcium diet promotes later-life obesity induced by a high-fat diet.

The aim of this study was to investigate the effects of a postweaning low-calcium diet on later obesity and explore the underlying mechanisms. Ninety-six male rats were weaned at 3 weeks of age, fed standard (STD: 0.50% calcium, n=48) and low-calcium (LC: 0.

The calcium-sensing receptor promotes adipocyte differentiation and adipogenesis through PPARγ pathway.

Adipocyte differentiation and adipogenesis are closely related to obesity and obesity-induced metabolic disorders. The calcium-sensing receptor (CaSR) has been reported to play an antilipolytic role in human adipocyte and regulate cell differentiation in many tissues. However, the effects of CaSR on adipocyte differentiation and adipogenesis have not been clarified.

The calcium-sensing receptor affects fat accumulation via effects on antilipolytic pathways in adipose tissue of rats fed low-calcium diets.

Low-calcium intake is associated with increased risk of obesity, but the mechanism underlying this is not clear. We previously reported that the calcium-sensing receptor (CaSR) plays an important role in modulating the expression of rate-limiting lipolysis enzymes in human adipocytes. In the present study, rats were fed diets containing normal [0.
