Glial Endozepines Reverse High-Fat Diet-Induced Obesity by Enhancing Hypothalamic Response to Peripheral Leptin.

Research on energy homeostasis has focused on neuronal signaling; however, the role of glial cells has remained little explored. Glial endozepines exert anorexigenic actions by mechanisms which remain poorly understood. In this context, the present study was designed to decipher the mechanisms underlying the anorexigenic action of endozepines and to investigate their potential curative effect on high-fat diet-induced obesity.

Interaction between nesfatin-1 and oxytocin in the modulation of the swallowing reflex.

Nesfatin-1, an 82-amino acid peptide encoded by the secreted precursor nucleobinin-2 (NUCB2), exerts potent anorexigenic action independently of leptin signaling. This propensity has propelled this peptide and its analogues as potential anti-obesity drug candidates. However, a more extensive comprehension of its biological actions is needed prior to envisaging its potential use in the treatment of metabolic diseases.

The effect of maternal iron deficiency on zinc and copper levels and on genes of zinc and copper metabolism during pregnancy in the rat.

Fe deficiency is relatively common in pregnancy and has both short- and long-term consequences. However, little is known about the effect on the metabolism of other micronutrients. A total of fifty-four female rats were fed control (50 mg Fe/kg) or Fe-deficient diets (7·5 mg/kg) before and during pregnancy.

The effect of amino acid deprivation on the transfer of iron through Caco-2 cell monolayers.

Iron (Fe) metabolism is modified by many nutritional factors. Amino acids (AA) play a central role in various biological processes, such as protein synthesis and energy supply. However, the influence of AA status on iron metabolism has not been investigated.
