Effects of altered tonicity by sodium chloride onl-tryptophan binding to hepatic nuclei

“…Although the inhibitory effects were similar under the two different experimental conditions, the mechanism for each may be different in that the NaCl concentration in hepatic cells after administration of NaCl in vivo was appreciably higher than the low levels added in vitro to the isolated hepatic nuclei. added sodium chloride; nuclear envelopes; rats THE ENHANCEMENT OF HEPATIC protein synthesis in mice, rats, rabbits, and pigs, which is rapidly induced by the administration of L-tryptophan (27,(29)(30)(31)(32)(33)35), has been the central focus of our interest for many years. In attempting to unravel the mechanism involved in this stimulatory response, we have discovered that hepatic nuclei, particularly their nuclear envelopes, have a specific receptor for L-tryptophan (15,16).…”
