Notch signaling regulates metabolic heterogeneity in glioblastoma stem cells. [PDF]
, 2017 Glioblastoma (GBM) stem cells (GSCs) reside in both hypoxic and vascular microenvironments within tumors. The molecular mechanisms that allow GSCs to occupy such contrasting niches are not understood.

Impact of limited solvent capacity on metabolic rate, enzyme activities, and metabolite concentrations of S. cerevisiae glycolysis [PDF]
, 2008 The cell's cytoplasm is crowded by its various molecular components, resulting in a limited solvent capacity for the allocation of new proteins, thus constraining various cellular processes such as metabolism.

Advanced Science, EarlyView.This study presents telomere‐to‐telomere genome assemblies for two populations of Larimichthys crocea. We identified centromere‐specific tandem repeats invaded by LTR/ERV1 retrotransposons, unique 5S rRNA enrichment patterns, and population‐specific structural variants. Comparative genomic analyses further reveal distinct adaptive mechanisms in the MYD

Warburg Effect, Glutamine, Succinate, Alanine, When Oxygen Matters
Biology, 2021 Cellular bioenergetics requires an intense ATP turnover that is increased further by hypermetabolic states caused by cancer growth or inflammation. Both are associated with metabolic alterations and, notably, enhancement of the Warburg effect (also known

Is Lactate an Oncometabolite? Evidence Supporting a Role for Lactate in the Regulation of Transcriptional Activity of Cancer-Related Genes in MCF7 Breast Cancer Cells. [PDF]
, 2019 Lactate is a ubiquitous molecule in cancer. In this exploratory study, our aim was to test the hypothesis that lactate could function as an oncometabolite by evaluating whether lactate exposure modifies the expression of oncogenes, or genes encoding ...

Advanced Science, EarlyView.Polystyrene nanoplastics (PS‐NPs) administered via oral exposure accelerate triple‐negative breast cancer (TNBC) progression by synergistically modulating gut microbiota‐derived glutamate production and platelet activation. This study uncovers a pivotal crosstalk between microbial metabolites and platelet‐tumor interactions, offering mechanistic ...

Medium alkalization due to carbon metabolism is largely responsible for inhibition of bacterial growth by Vibrio cholerae supernatants [PDF]
, 2017 Vibrio cholerae is the causative agent of the diarrheal disease cholera. Many Vibrio species secrete antimicrobial factors, though the identity of such a factor has not been determined for any V. cholerae strain.

Advanced Science, EarlyView.SCAP/ARDS patients show reduced unsaturated fatty acids (UFAs) but higher PARK7 and lactate in plasma. PARK7 correlates positively with lactate and negatively with UFAs. Pulmonary endothelial cell multi‐omics show FADS1/2 downregulation and impaired PUFA metabolism. Lactate boosts PARK7 via H3K14 lactylation, and PARK7 then restores FADS1/2.

Lactate activates HIF-1 in oxidative but not in Warburg-phenotype human tumor cells. [PDF]
PLoS ONE, 2012 Cancer can be envisioned as a metabolic disease driven by pressure selection and intercellular cooperativeness. Together with anaerobic glycolysis, the Warburg effect, formally corresponding to uncoupling glycolysis from oxidative phosphorylation ...

Effects of Low pH on Lactate Dehydrogenase Kinetics of Diving and Nondiving Reptiles [PDF]
, 1986 The properties of lactate dehydrogenase were examined in two snake species, Nerodia rhombifera and Elaphe obsoleta, and a turtle species, Pseudemys scripta.
