Lactate activates HIF-1 in oxidative but not in Warburg-phenotype human tumor cells.

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 ...

Harnessing energy metabolism for enhanced bone defect repair: Mechanisms and therapeutic strategies

VIEW, EarlyView.
This review addresses the critical challenge of bone defect repair by focusing on the underexplored role of cellular energy metabolism. It synthesizes regulatory mechanisms in bone‐forming cells and sums up innovative strategies—leveraging cell derivatives, active factors, and biomimetic scaffolds—to modulate metabolism for enhanced regeneration.

The Role of Tissue Oxygen Tension in Dengue Virus Replication

Cells, 2018
Low oxygen tension exerts a profound effect on the replication of several DNA and RNA viruses. In vitro propagation of Dengue virus (DENV) has been conventionally studied under atmospheric oxygen levels despite that in vivo, the tissue microenvironment ...

Starvation of Cancer via Induced Ketogenesis and Severe Hypoglycemia

, 2014
Neoplasms are highly dependent on glucose as their substrate for energy production and are generally not able to catabolize other fuel sources such as ketones and fatty acids.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Prenatal Environmental Hypoxia Enhances Adult Hypoxia Tolerance in Brandt's Voles (Lasiopodomys brandtii): Behavioral and Transcriptomic Insights

Integrative Zoology, EarlyView.
Prenatal hypoxia enhances adult hypoxia tolerance in Brandt's voles, preserving cognitive and memory functions. Transcriptomic analysis reveals adaptive changes in energy metabolism, oxygen transport, and neuroprotective mechanisms, highlighting developmental plasticity.

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

Integrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Immunometabolic effects of lactate on humoral immunity in healthy individuals of different ages

Nature Communications
Aging is characterized by chronic systemic inflammation and metabolic changes. We compare the metabolic status of B cells from young and elderly donors and found that aging is associated with higher oxygen consumption rates, and especially higher ...
