Abstract

One-carbon metabolism plays a critical role in both DNA methylation and DNA synthesis. Accumulating evidence has shown that interruptions of this pathway are associated with many disease outcomes including cardiovascular diseases and cancers. Mechanistic studies have been performed on genetic polymorphisms involved in one-carbon metabolism. However, expression profiles of these inter-related genes are not well-known. In this study, we examined the gene expression profiles of 11 one-carbon metabolizing genes by quantifying the mRNA level of the lymphocyte among 54 healthy individuals and explored the correlations of these genes. We found these genes were expressed in lymphocytes at moderate levels and showed significant inter-person variations. We also applied principle component analysis to explore potential patterns of expression. The components identified by the program agreed with existing knowledge about one-carbon metabolism. This study helps us better understand the biological functions of one-carbon metabolism.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Formate triggered upregulation of differentially expressed genes involved in one-carbon metabolism (Shmt2, Cth) and Nrf2-regulated genes (Cth, mt-Nd4, Tkt).

    “formate triggered an upregulation of differentially expressed genes (DEGs) involved in 1C metabolism, such as serine hydroxymethyltransferase 2 (Shmt2)42,58 and cystathionine gamma-lyase (Cth)59, as well as genes regulated by Nrf2 (e.g.: Cth60, NADH dehydrogenase 4 (mt-Nd4)61 and transketolase (Tkt)62,63) (Figure 6L and Table S3).”

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.
