Stimulation of de novo pyrimidine synthesis by growth signaling through mTOR and S6K1

What this study shows

mTORC1-S6K1 stimulates de novo pyrimidine synthesis by phosphorylating CAD.

Abstract

ShowHide

Cellular growth signals stimulate anabolic processes. The mechanistic target of rapamycin complex 1 (mTORC1) is a protein kinase that senses growth signals to regulate anabolic growth and proliferation. Activation of mTORC1 led to the acute stimulation of metabolic flux through the de novo pyrimidine synthesis pathway.

At a glance

Evidence type M Molecular — cells, biochemistry, structure Marked M because it is molecular or in-vitro work (model: Mammalian cells) rather than a whole-organism health-outcome study. That is often exactly where causal biology gets established -- the code says which system the finding was shown in, and nothing about how good the work is.
