However, increased intracellular concentrations of leucine can stimulate protein synthesis independent of mTOR (5). (siimland.com)
Cellular transport, migration and polarization all require membrane reorganization as well as initiation and maintenance of intracellular concentration gradients of distinct molecular species. (dresden-ipp.de)
The increase, observed as early as 60 seconds after the addition of corticotropin - releasing factor, suggests that changes in the intracellular concentration of the cyclic nucleotide coincide with or precede the secretion of adrenocorticotropic hormone in response to corticotropin - releasing factor.
