Prevalence of melanocortin system transcripts in rat salt homeostasis endocrine tissues.

Melanocortin receptors have been implicated in the confounding factors of cardiovascular diseases such as obesity, insulin resistance and salt-sensitive hypertension. The aim of this study was determine how increased dietary salt intake affects the expression profiles of melanocortin system genes in relevant endocrine tissues. Total RNA was isolated from the pituitary and adrenal glands of Wistar Kyoto (WKY) and stroke-prone spontaneously hypertensive rats (SP-SHR) and subjected to real-time PCR analysis.

GABAergic phenotypic differentiation of a subpopulation of subventricular derived migrating progenitors.

Olfactory bulb interneurons are continuously generated throughout development and in adulthood. These neurons are born in the subventricular zone (SVZ) and migrate along the rostral migratory stream into the olfactory bulb where they differentiate into local interneurons. To investigate the differentiation of GABAergic interneurons of the olfactory bulb we used a transgenic mouse which expresses green fluorescent protein (GFP) under the control of the glutamic acid decarboxylase 65 kDa (GAD65) promoter.
