LRPPRC confers enhanced oxidative phosphorylation metabolism in triple-negative breast cancer and represents a therapeutic target

Journal of Translational Medicine
Background Triple-negative breast cancer (TNBC) is a highly malignant tumor that requires effective therapeutic targets and drugs. Oxidative phosphorylation (OXPHOS) is a metabolic vulnerability of TNBC, but the molecular mechanism responsible for the ...

Fluorescent Visualization of In Vitro Mitochondrial DNA Transcription [PDF]

, 2019
Mitochondria are important organelles within eukaryotic cells especially for their role in metabolism and ATP production by the oxidative phosphorylation (OXPHOS) pathway. In human cells there are approximately 80 protein subunits that make up the OXPHOS

Secondary coenzyme Q₁₀ deficiencies in oxidative phosphorylation (OXPHOS) and non-OXPHOS disorders

, 2016
We evaluated the coenzyme Q(10) (CoQ) levels inpatients who were diagnosed with mitochondrial oxidative phosphorylation (OXPHOS) and non-OXPHOS disorders (n = 72). Data from the 72 cases in this study revealed that 44.4% of patients showed low CoQ concentrations in either their skeletal muscle or skin fibroblasts.

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Repeated Disuse Atrophy Imprints a Molecular Memory in Skeletal Muscle: Transcriptional Resilience in Young Adults and Susceptibility in Aged Muscle

Advanced Science, EarlyView.
Repeated disuse imprints a molecular memory in skeletal muscle, conferring transcriptional resilience in young adults but exaggerated susceptibility in aged muscle, driven by epigenetic regulation of aerobic metabolism, mitochondrial and NAD+ pathways.

Semiconducting Polymer Nanoparticles Enable Light‐Controlled Bidirectional Modulation of Nitric Oxide in Endothelial Cells

Advanced Science, EarlyView.
Bimodal modulation of nitric oxide in endothelial cells is achieved by light‐sensitive polymer nanoparticles. In dark, P3HT/PEDOT:PSS NPs boost intracellular ·NO, upregulate both endothelial and induced nitric oxide synthase, and drive a metabolic shift toward glycolysis.

Illuminating Mitochondrial RNA G‐Quadruplexes as Structural Brakes on RNA Granule Assembly and OXPHOS

Advanced Science, EarlyView.
A new fluorescent probe, MitoQUMA, brings mitochondrial RNA G‐quadruplexes (mtRNA G4s) into view in live cells. This tool reveals that excessive mtRNA G4 formation halts mitochondrial RNA granule (MRG) assembly, opposite to the phase‐separation role of cytoplasmic RNA G4s. A chemical genetic screen further identifies a Wnt/β‐catenin–GRSF1–mtRNA G4 axis
