title: [In vitro biosynthesis of beta-lipotropin in brain tissue].
abstract: We have recently developed methods to identify biosynthetized beta-endorphin and beta-lipotropin (beta-LPH) following incubation of Rat pars intermedia with radioactive amino acids. We used the same approach for rat brain tissue. In the striatum we found a peptide similar to beta-LPH while its identification in hypothalamus was less positive. This is the first demonstration of such biosynthesis and it could well be an important step in determining the biosynthetic patterns of cerebral endorphins and enkephalins.
