mTORC1 induces purine synthesis through control of the mitochondrial tetrahydrofolate cycle
Open accessAbstract
Controlling supplies for DNA and RNA synthesis: The mTORC1 protein kinase complex regulates anabolic metabolism and coordinates cellular signals that promote growth with availability of required precursor metabolites. Signaling through mTORC1 controls pyrimidine synthesis. Ben-Sahra et al. found that mTORC1 also functions by a different mechanism to regulate purine biosynthesis, thus generating precursors for the synthesis of RNA and DNA (see the Perspective by Ma and Jones). Signaling by mTORC1 caused accumulation of the transcription factor ATF4, which enhances production of the enzyme methylenetetrahydrofolate dehydrogenase 2, thus leading to increased production of the purine nucleotides needed for cell growth.

“Activation of mTOR can increase ribose synthesis via the oxidative pentose phosphate pathway (Duvel et al., 2010) and enhance flux through the pyrimidine and purine synthesis pathways (Ben-Sahra et al., 2013; Ben-Sahra et al., 2016; Robitaille et al., 2013), suggesting that targeting nucleotide metabolism in tumor contexts with mTOR hyperactivation may be more effective.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
