Study Title | Effect of feeding and the mTORC1 activity on metabolism in Caenorhabditis elegans |
Study Summary | Cellular growth and organismal development are remarkably complex processes that require the nutrient-responsive kinase mTORC1. Anticipating that important mTORC1 functions remained to be identified, we employed genetic and bioinformatic screening in C. elegans to uncover mechanisms of mTORC1 action. Here we show that during larval growth nutrients induce an extensive reprogramming of gene expression and alternative mRNA splicing by acting through mTORC1. mTORC1 regulates mRNA splicing and production of protein-coding mRNA isoforms largely independently of its target p70S6K, by increasing the activity of the serine/arginine-rich (SR) protein RSP-6 (SRSF3/7) and other splicing factors. mTORC1-mediated mRNA splicing regulation is critical for growth, mediates nutrient control of mechanisms that include energy, nucleotide, amino acid, and other metabolic pathways, and may be conserved in humans. Although mTORC1 inhibition delays aging, mTORC1-induced mRNA splicing promotes longevity, suggesting that when mTORC1 is inhibited enhancement of this splicing might provide additional anti-aging benefits. |
