Background: Ginseng Berry Concentrate (GBC) enhances exercise capacity in mice, but the effects of its key component, ginsenoside Re (G-Re), on aging and mitochondrial function are not well understood. This study investigates the impact of G-Re on mitophagy and its potential to promote healthy aging.
Methods: Experiments in C2C12 myocytes and HeLa-mitoKeima-PARKIN cells assessed GBC and G-Re's effects on mitophagy, supported by Gene Set Enrichment Analysis. G-Re was identified as the primary component of GBC via high-performance liquid chromatography. The influence of G-Re on lifespan and healthspan was examined in , with a focus on mitophagy pathways.
Results: GBC and G-Re significantly induced mitophagy and enhanced mitochondrial gene expression, improving mitochondrial function. G-Re extended lifespan and healthspan in , effects absent in mitophagy-impaired mutants.
Conclusion: G-Re enhances mitochondrial function and promotes healthy aging through mitophagy, suggesting its potential for mitigating age-related functional declines.

Heart failure (HF) is a multifactorial and pathophysiological complex syndrome, involving not only neurohormonal activation but also oxidative stress, chronic low-grade inflammation, and metabolic derangements. Central to the cellular defence against oxidative damage is nuclear factor erythroid 2-related factor 2 (Nrf2), a transcription factor that orchestrates antioxidant and cytoprotective responses. Preclinical in vitro and in vivo studies reveal that Nrf2 signalling is consistently impaired in HF, contributing to the progression of myocardial dysfunction.

Migrasomes are newly discovered, migration-dependent organelles that mediate the release of cellular contents into the extracellular environment through a process known as migracytosis. Since their identification in 2014, growing evidence has highlighted their critical roles in intercellular communication, organ development, mitochondrial quality control, and disease pathogenesis. Migrasome biogenesis is a complex, multi-step process tightly regulated by lipid composition, tetraspanin-enriched microdomains, and molecular pathways involving sphingomyelin synthase 2, Rab35, and integrins.

Multimorbidity of chronic diseases is one of the most common health issues among older adults, and the resulting demand for long-term medical care and management imposes a considerable burden on healthcare systems. Muscle strength, a core indicator of overall health status, is closely associated with the risk of developing multimorbidity of chronic diseases in older adults. Decline in muscle strength not only increases the risk of multimorbidity of chronic diseases but also interacts with it to exacerbate disease burden.

Aims: Skeletal muscle energetic augmentation might be a mechanism via which intravenous iron improves symptoms in heart failure, but no direct measurement of intrinsic mitochondrial function has been performed to support this notion. This molecular substudy of the FERRIC-HF II trial tested the hypothesis that ferric derisomaltose (FDI) would improve electron transport chain activity, given its high dependence on iron-sulfur clusters which facilitate electron transfer during oxidative phosphorylation.
Methods And Results: Vastus lateralis skeletal muscle biopsies were taken before and 2 weeks after randomization.

Background/aims: Endoplasmic reticulum (ER) stress in hepatocytes plays a causative role in alcohol-associated liver disease (ALD). The incomplete inhibition of ER stress by targeting canonical ER stress sensor proteins suggests the existence of noncanonical ER stress pathways in ALD pathology. This study aimed to delineate the role of RAB25 in ALD and its regulatory mechanism in noncanonical ER stress pathways.
