- Researchers have identified over 200 metabolic enzymes directly on human DNA, revealing a previously unknown "mini-metabolism" within the cell's nucleus.
- This discovery challenges traditional views, as metabolism and genome regulation were largely considered separate biological systems, with metabolic enzymes typically found in mitochondria and cytoplasm.
- According to EurekAlert!, these enzymes create a "nuclear metabolic fingerprint" that varies across different cell types, tissues, and even cancers.
- The presence of these enzymes suggests they may influence crucial cellular processes like gene expression and DNA repair.
- As reported by SciTechDaily, this hidden mini-metabolism could impact how cancers respond to treatment, offering new insights into tumor growth and drug resistance.
- The study, published in Nature Communications, highlights that some enzymes, like IMPDH2, play a role in DNA repair, gathering around chromatin when DNA is damaged.
