Adipose tissue aging as a risk factor for metabolic organ abnormalities: mechanistic insights and the role of exercise interventions.

Aging is widely regarded as an irreversible arrest of cellular growth and proliferation, often accompanied by systemic metabolic organ abnormalities, ultimately reducing quality of life and increasing mortality in the elderly. Multi-organ transcriptomic analyses suggest that adipose tissue is among the earliest organs to respond to aging, characterized by changes in fat content and redistribution of adipose tissue, decline in thermogenic adipose function, reduced proliferation and differentiation capacity of adipose progenitor and stem cells, accumulation of senescent cells, and immunosenescence. These alterations may act synergistically and play a role in abnormalities in metabolic organs including the cardiovascular, liver, skeletal muscle, and brain.

Ferroptosis in neurodegenerative diseases: potential mechanisms of exercise intervention.

Neurodegenerative diseases represent a major global cause of mortality and disability. These disorders are characterized by complex pathogenesis and currently lack effective therapeutic strategies.

Projected impacts of ocean warming on pelagic ecosystems in the Western and Central Pacific Ocean using a multi-species size-spectrum model.

Ocean warming may alter food web structure and species interactions in pelagic ecosystems, significantly impacting tuna population dynamics. However, few studies have assessed those impacts from the perspective of species interaction and ecosystems. In this study, we developed a multi-species size-spectrum model (MSSM) incorporating Chinese longline fisheries data and public datasets to assess ocean warming effects on the Western and Central Pacific Ocean (WCPO) ecosystem under four climate scenarios (SSP1-2.

The role of mitophagy in metabolic diseases and its exercise intervention.

Mitochondria are energy factories that sustain life activities in the body, and their dysfunction can cause various metabolic diseases that threaten human health. Mitophagy, an essential intracellular mitochondrial quality control mechanism, can maintain cellular and metabolic homeostasis by removing damaged mitochondria and participating in developing metabolic diseases. Research has confirmed that exercise can regulate mitophagy levels, thereby exerting protective metabolic effects in metabolic diseases.

Protective effects of paeoniflorin against cobalt chloride-induced apoptosis of endothelial cells via HIF-1α pathway.

Accumulating evidence has suggested the importance of hypoxia in the initiation and development of atherosclerotic lesion, and hypoxia has a profound impact on endothelial cell properties during cardiovascular disease processes. Paeoniflorin, isolated from the root of Paeonia lactiflora pall, can protect endothelial cells from hypoxic damage in a variety of ways, such as by enhancing the production of nitric oxide (NO) and decreasing the expressions of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1). This study evaluated the protective effects of paeoniflorin against cobalt chloride (CoCl2, a hypoxia-mimicking agent)-induced apoptosis of endothelial cells (CRL-1730) and the underlying mechanisms in vitro.
