Exercise Capacity, Dark Chocolate, and Mitochondrial Efficiency
In sedentary adults, dark chocolate intake improved exercise-related performance measures, including work achieved and VO2 max trends, with mechanistic data pointing toward mitochondrial efficiency and upstream signaling changes.
Cell Membrane Signaling and Endothelial Response to (-)-Epicatechin
This paper provides evidence that (-)-epicatechin can trigger endothelial signaling through a cell-surface receptor mechanism, supporting membrane-initiated signaling rather than only intracellular antioxidant activity.
White Fat Browning and Mitochondrial Biogenesis in Adipose Tissue
This study found that (-)-epicatechin promoted browning-related changes in adipocytes and white adipose tissue, with associated improvements in mitochondrial function and thermogenic markers.
Endothelial Cell Aging, Vascular Function, and Nitric Oxide
This study identifies arginase inhibition as a key mechanism by which (-)-epicatechin reverses endothelial cell aging, tying vascular anti-aging effects to a defined enzymatic pathway.
Oxidative Stress Regulation in Skeletal Muscle Under Clinical Metabolic Strain
In patients with heart failure and type 2 diabetes, (-)-epicatechin-rich cocoa modulated oxidative-stress regulators in skeletal muscle, supporting an effect on redox biology in clinically relevant tissue.
Mitochondrial Biogenesis, Muscle Regeneration, and Human Neuromuscular Disease
In adults with Becker muscular dystrophy, (-)-epicatechin increased markers of mitochondrial biogenesis and muscle regeneration, suggesting a potentially relevant biological response in a human neuromuscular condition.
Résistance à la fatigue, capacité oxydative et énergie musculaire
Cette étude animale a montré que (-)-epicatechin la résistance à la fatigue et la capacité oxydative des muscles de souris, ce qui corrobore l'hypothèse d'un effet sur le métabolisme mitochondrial ou oxydatif dans le muscle squelettique.
Cognitive Recovery, Inflammation, and Mitochondrial Restoration in Gulf War Illness
This study examined a Gulf War illness model and reported neurological restorative effects with (-)-epicatechin treatment, extending the literature into neurobehavioral and neuroinflammatory contexts.
Neuroinflammation, Tau Pathology, and Brain Aging
In aged mice, (-)-epicatechin reduced oxidative stress, neuroinflammation, and tau hyperphosphorylation in the hippocampus, while also improving several behavioral and inflammatory measures.
Neurogenesis, Short-Term Memory, and Nitric Oxide Signaling
This mouse study compared (-)-epicatechin with its stereoisomer (+)-epicatechin for effects on frontal-cortex-dependent short-term working memory and neurogenesis-related markers. Both compounds increased markers linked to neuronal proliferation, capillary density, nitric-oxide signaling, and memory performance, with (+)-epicatechin generally showing stronger effects.
Brain Protein Structure and Cellular Stability
This study evaluated whether (-)-epicatechin could restore dystrophin-associated protein complex (DAPC) components and dysbindin in the prefrontal cortex of mdx mice, a model of Duchenne muscular dystrophy. After four weeks of treatment, (-)-epicatechin partially recovered multiple DAPC-related proteins and associated interactions, suggesting a shift toward a healthier brain protein profile.
Epicatechin and Breast Cancer Cell Migration in Vitro
This in vitro study found that (-)-epicatechin reduced proliferation, migration, and invasion markers in murine breast cancer cells under experimental conditions.
