Explicit consideration of topological and parameter uncertainty gives new insights into a well-established model of glycolysis [PDF]

open access: yes, 2013
Previous models of glycolysis in the sleeping sickness parasite Trypanosoma brucei assumed that the core part of glycolysis in this unicellular parasite is tightly compartimentalized within an organelle, the glycosome, which had previously been shown to ...

Pyruvate Kinase M2 and Cancer: The Role of PKM2 in Promoting Tumorigenesis

open access: yesFrontiers in Oncology, 2020
Pyruvate kinase plays a pivotal role in regulating cell metabolism. The final and rate-limiting step of glycolysis is the conversion of Phosphoenolpyruvate (PEP) to Pyruvate, which is catalyzed by Pyruvate Kinase. There are four isomeric, tissue-specific

Warburg Effect, Glutamine, Succinate, Alanine, When Oxygen Matters

open access: yesBiology, 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

Ligilactobacillus Murinus and Lactobacillus Johnsonii Suppress Macrophage Pyroptosis in Atherosclerosis through Butyrate‐GPR109A‐GSDMD Axis

open access: yesAdvanced Science, EarlyView.
Oral aspirin administration induces intestinal expansion of Lactobacillus murinus and Lactobacillus johnsonii, which suppresses the progression of atherosclerosis. This microbial expansion significantly enhances butyrate production by providing lactate as a metabolic substrate, thereby fostering the growth of butyrate‐producing bacteria. Butyrate plays

Phosphodiesterase Type 5 Inhibitors, Sport and Doping [PDF]

open access: yes, 2017
Phosphodiesterase type 5 inhibitors (PDE5i) (e.g., sildenafil, tadalafil, vardenafil, and avanafil) are drugs commonly used to treat erectile dysfunction, pulmonary arterial hypertension, and benign prostatic hyperplasia.

Transcriptomic signature of Leishmania infected mice macrophages: a metabolic point of view.

open access: yesPLoS Neglected Tropical Diseases, 2012
We analyzed the transcriptional signatures of mouse bone marrow-derived macrophages at different times after infection with promastigotes of the protozoan parasite Leishmania major.

Mesencephalic Astrocyte‐Derived Neurotrophic Factor Binds BAX to Preserve Mitochondrial Homeostasis and Energy Metabolism for Relieving Myocardial Hypertrophy

open access: yesAdvanced Science, EarlyView.
MANF in cardiomyocytes interacts with BAX to impede BAX mitochondrial translocation and cytochrome c release, further stabilizing mitochondrial structure and energy supply to relieve myocardial apoptosis and hypertrophy, which indicates MANF as a novel cardioprotective factor to have a promising clinical application for myocardial hypertrophy ...

Effects of Low pH on Lactate Dehydrogenase Kinetics of Diving and Nondiving Reptiles [PDF]

open access: yes, 1986
The properties of lactate dehydrogenase were examined in two snake species, Nerodia rhombifera and Elaphe obsoleta, and a turtle species, Pseudemys scripta.

Impact of limited solvent capacity on metabolic rate, enzyme activities, and metabolite concentrations of S. cerevisiae glycolysis [PDF]

open access: yes, 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.

FOXQ1 Regulates Brain Endothelial Mitochondrial Function by Orchestrating Calcium Signaling and Cristae Morphology

open access: yesAdvanced Science, EarlyView.
FOXQ1 emerges as a master transcriptional regulator of brain endothelial metabolism, orchestrating mitochondrial function through dual control of calcium signaling and cristae organization. This study reveals that brain endothelial cells rely on oxidative phosphorylation rather than glycolysis alone, challenging the current metabolic paradigm and ...
