mTORC1 induces purine synthesis through control of the mitochondrial tetrahydrofolate cycle

Ben-Sahra I, Manning BD et al. · 2016 · Science · Atlas ID BEN2016

What this study shows

mTORC1 promotes purine synthesis via ATF4-driven mitochondrial tetrahydrofolate metabolism.

Abstract

ShowHide

In response to growth signals, mechanistic target of rapamycin complex 1 (mTORC1) stimulates anabolic processes underlying cell growth. We found that mTORC1 increases metabolic flux through the de novo purine synthesis pathway in various mouse and human cells, thereby influencing the nucleotide pool available for nucleic acid synthesis.

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.
