We recently developed a general method for determining tissue sites of degradation of plasma proteins in vivo that made use of covalently attached radioactive sucrose. On degradation of the protein, the sucrose remained trapped in the cells as a cumulative marker of protein degradation. The method described here depends on the same principles, but uses an(More)
The enantiomers of a number of catecholamines, including (alpha S)- and (alpha R)-erythro-alpha-methylepinephrine, were evaluated for their capacity to compete for binding sites in rat forebrain homogenates with [3H]prazosin, a ligand which selectively binds to adrenergic receptors of the alpha 1 subtype. (alpha R)-erythro-alpha-Methylepinephrine is devoid(More)
We have previously described in rats the selective uptake of HDL-associated cholesterol esters (traced by [3H]cholesteryl oleyl ether) in excess of the uptake of HDL-associated apoA-I. In the present studies we show that the mechanism also exists in cultured cells of human and mouse origin as well. This selective uptake represents a net uptake of(More)
The construction of a large dendritic arbor requires robust growth and the precise delivery of membrane and protein cargoes to specific subcellular regions of the developing dendrite. How the microtubule-based vesicular trafficking and sorting systems are regulated to distribute these dendritic development factors throughout the dendrite is not well(More)
13 Precise patterning of dendritic fields is essential for the formation and function of 14 neuronal circuits. During development, dendrites acquire their morphology by 15 exuberant branching. How neurons cope with the increased load of protein 16 production required for this rapid growth is poorly understood. Here we show that 17 the physiological unfolded(More)
