Redistribution of microvilli and membrane enzymes in isolated rat proximal tubule cells.

abstract：:Circulating glucocorticoid (GC) levels are thought to modulate the basal activity of pro-opiomelanocortin (POMC) neurons within the mediobasal hypothalamus (MBH) of the male rat. In a recent study we demonstrated that Fos-immunoreactivity (Fos-IR) was spontaneously induced throughout the dark phase of the light/dark c...
