Sentences with phrase «s6 kinase»

mTORC1 is the central component of the insulin - signaling cascade [insulin / insulin - like growth factor (IGF)-- phosphatidylinositol 3 - kinase (PI3K) pathway)(Fig. 1) that regulates protein synthesis and mRNA translation through 2 primary mechanisms: 1) inactivation of the repressor of mRNA translation, eukaryotic translation initiation factor 4E - binding protein 1 (eIF4E - BP1), and 2) the activation of 70 - kDa ribosomal protein S6 kinase.

Furthermore, phosphorylation states of intracellular regulators of muscle protein synthesis (mTOR, 70 - kDa S6 kinase, and eIF4E - BP1) were similar in pigs that consumed a leucine - supplemented, low - protein diet or a high - protein diet without additional leucine, highlighting the potential synthetic effect resulting from increased leucine intake.

IGF - I is perhaps the most important mediator of muscle growth and repair (49), possibly through the use of protein kinase B — mechanistic target of rapamycin — p70 ribosomal protein S6 kinase signaling.

Chen et al. (62) combined mutation in daf - 2 (similar allele to this study) with mutation in rsks - 1, C. elegans S6 kinase to reveal extreme longevity.

One mechanism is protein synthesis by key regulators such as S6 kinase (S6K).

Arginine stimulates cdx2 - transformed intestinal epithelial cell migration via a mechanism requiring both nitric oxide and phosphorylation of p70 S6 kinase.

S6 kinase localizes to the presynaptic active zone and functions with PDK1 to control synapse development.

Most cells do not divide until they reach a size characteristic of each cell type, and Thomas and his colleagues suspect that S6 kinase helps to regulate that signal.
