Summary: Mitochondrial electron transport chain (ETC) dysfunction elevates the NADH/NAD+ ratio to cause metabolic derangements. Here we describe a protocol to measure the NADH/NAD+ ratio and analyze the rewiring of glucose metabolism using [4-2H]-glucose,

In vitro interactions of phenformin with serum lipoproteins and consequences thereof
Turbidity developed when phenformin was added to human serum; this turbidity increased in a sigmoidal fashion with rising concentrations of phenformin (5-50 nmole/1). Centrifugation produced clearing of the solution, with collection of particulate matter

Defect engineering for highly efficient and stable perovskite top cells for Si tandems
Defect passivation in wide‐bandgap perovskites is essential for enabling high‐efficiency and stable perovskite/Si tandem solar cells. Bulk, surface, and buried‐interface passivation strategies focus on suppressing nonradiative recombination, ion migration, and halide segregation, thereby clarifying critical design principles for next‐generation tandem ...

Pancreatic cancer stem cells (CSCs) maintain stemness and tumorigenicity through NDUFS1‐mediated complex I activity, which is transcriptionally upregulated via the CD147‐STAT3 signaling axis. Enhanced oxidative phosphorylation (OXPHOS) and NAD+ production driven by this CD147‐NDUFS1 axis subsequently trigger the SIRT1‐DNMT1 metaboloepigenetic signaling

How to starve cancer cells when nutrients are abundant
Metabolic flexibility represents a potential point of attack for novel cancer treatments. We recently described the signaling mechanism inducing a metabolic shift in response to metformin and phenformin in leukemia and lymphoma cells.

Phenformin promotes breast cancer apoptosis.
(A) MCF7, ZR-75-1, MDA-MB-231 and SUM1315 cells treated with or without phenformin were double-stained with Annexin V and PI, and then analyzed by flow cytometry. (B) The percentages of Annexin V+/PI- cells(early apoptosis) were plotted.

ABSTRACT Osteosarcoma, the most common primary malignant bone tumour, presents significant treatment challenges due to its complex tumour microenvironment and the development of chemoresistance. This study employs single‐cell transcriptomics to investigate chemotherapy‐induced changes in osteosarcoma at both the cellular and molecular levels.

LKB1–AMPK Signaling Pathway in Cardiovascular and Other Diseases
The LKB1–AMPK pathway has a central regulatory role in various diseases. Dysfunction of this pathway can lead to pathological processes in cardiovascular diseases (atrial fibrillation, myocardial infarction, myocardial hypertrophy, atherosclerosis), metabolic diseases (diabetes and kidney disease), neurodegenerative diseases (Alzheimer's disease ...
