Carbon metabolism–mediated myogenic differentiation [PDF]
Nature Chemical Biology, 2010 The role of nutrients and metabolism in cellular differentiation is poorly understood. Using RNAi screening, metabolic profiling and small-molecule probes, we discovered that the knockdown of three metabolic enzymes-phosphoglycerate kinase (Pgk1), hexose-6-phosphate dehydrogenase (H6pd) and ATP citrate lyase (Acl)-induces differentiation of mouse C2C12

FEBS Open Bio, EarlyView.Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Straw and biochar strongly affect functional diversity of microbial metabolism in paddy soils
Journal of Integrative Agriculture, 2019 The application of straw and biochar is widely practiced for the improvement of soil fertility. However, its impact on microbial functional profiles, particularly with regard to paddy soils, is not well understood.

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Metabolic plasticity of central carbon metabolism protects mycobacteria [PDF]
Proceedings of the National Academy of Sciences, 2015 Central carbon metabolism (CCM) that transforms carbon through glycolysis, gluconeogenesis, the pentose phosphate pathway, and the TCA pathway into energy is essential for the physiology of Mycobacterium tuberculosis (Mtb). In contrast to other pathogens, humans are the only known reservoir of Mtb, where it mainly resides in macrophages of the primary ...

FEBS Open Bio, EarlyView.UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Evolution of Central Carbon Metabolism [PDF]
Molecular Cell, 2010 Organisms share a common core to their metabolic networks. But what determined this: chance, chemical necessity, or evolutionary optimization? In this issue of Molecular Cell, Noor et al. (2010) provide new evidence for selection of a network with optimal features from a broader set of possibilities.

FEBS Open Bio, EarlyView.NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Regulation of Symbiotic Nitrogen Fixation in Legume Root Nodules
Plants, 2019 In most legume nodules, the di-nitrogen (N2)-fixing rhizobia are present as organelle-like structures inside their root host cells. Many processes operate and interact within the symbiotic relationship between plants and nodules, including nitrogen (N ...

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants
FEBS Open Bio, EarlyView.Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...
