In Vitro | β-Melanocyte Stimulating Hormone is a powerful anti-inflammatory agent which effect is brought by activation of the central MC3/MC4 receptors and thereby inhibits NO production by inhibiting the translocation of transcription factor NF-κB to the nuclei of the brain cells and decreasing iNOS expression[1]. β-Melanocyte Stimulating Hormone has significantly higher at human MC4-R transfected into CHO cells (Ki=11.4±0.4 nM) and MC4-R in rat hypothalamic homogenates (Ki=22.5±2.3 nM)[2]. |
In Vivo | β-Melanocyte Stimulating Hormone suppresses LPS-induced nuclear translocation of the transcription factor NF-κB, and inhibits the expression of inducible nitric oxide synthase, and the following nitric oxide overproduction in the brain[1].β-Melanocyte Stimulating Hormone is a key ligand at the MC4-R populations that regulate feeding, and that inhibition of tonic release of β-MSH is one mechanism contributing to hunger in under-feeding[2]. |
Animal Admin | Mice[1] Male ICR mice weighing 23-25 g are housed under standard conditions (21-23°C, 12 h light-dark cycle) with unlimited access to food and water. The NO contents in the mouse forebrains are measured 6 h after drug administration using an electron paramagnetic resonance (EPR) method. β-Melanocyte Stimulating Hormone is administered intracisternaly (i.c.) with or without LPS, in a total injection volume of 10 μL (i.e., saline or 10 μL LPS with β-Melanocyte Stimulating Hormone ranging from 1 to 3 nM per animal). Control animals receive i.c. injection of 10 μL saline. The mice then receive intraperitoneal injections of spin trap reagents, i.e., 400 mg/kg DETC followed by subcutaneous injections of ferrous citrate (40 mg/kg ferrous sulphate+200 mg/kg sodium citrate, prepared directly in the syringe just before use), 0.5 h before decapitation. Thus, the spin trap reagents are administered 5.5 h after the LPS and peptide administration, when decapitation is performed 6 h after the start of the experiment. After that the forebrains are dissected and immediately frozen in liquid nitrogen. |
