AI Article Synopsis

  • Aging involves a gradual decline in tissue and organ function influenced by genetics, environment, nutrition, and lifestyle, with oxidative stress playing a key role in cellular aging and frailty.
  • Several factors contribute to aging, including genomic instability, telomere shortening, and mitochondrial dysfunction, all of which can be affected by diet and lifestyle choices.
  • Nutritional strategies such as the Mediterranean diet, dietary antioxidants, and caloric restriction show potential for promoting healthy aging and could lead to new biomarkers and treatments aimed at extending lifespan.

Article Abstract

Aging is characterized by a progressive loss of tissue and organ function due to genetic and environmental factors, nutrition, and lifestyle. Oxidative stress is one the most important mechanisms of cellular senescence and increased frailty, resulting in several age-linked, noncommunicable diseases. Contributing events include genomic instability, telomere shortening, epigenetic mechanisms, reduced proteome homeostasis, altered stem-cell function, defective intercellular communication, progressive deregulation of nutrient sensing, mitochondrial dysfunction, and metabolic unbalance. These complex events and their interplay can be modulated by dietary habits and the ageing process, acting as potential measures of primary and secondary prevention. Promising nutritional approaches include the Mediterranean diet, the intake of dietary antioxidants, and the restriction of caloric intake. A comprehensive understanding of the ageing processes should promote new biomarkers of risk or diagnosis, but also beneficial treatments oriented to increase lifespan.

Microplastics (MPs) are known as substantial environmental and health threats because of their pervasive existence and potential function in human diseases. This study is the first research in which a comprehensive analysis of various impacts of MPs on cancer cells is performed through pharmacological and in silico approaches. Moreover, our results demonstrate that MPs have both promotive and suppressive impacts on cancer cells, changing some of the important features of these kinds of cells including cellular viability, migration, metastasis, and apoptosis.

The Translation Initiation Factor eIF2Bα Regulates Development, Stress Response, Amylase Production, and Kojic Acid Synthesis in the Fungus Aspergillus oryzae.

Curr Microbiol

January 2025

Engineering Technological Center of Fungus Active Substances of Fujian Province, College of Biological Sciences and Technology, Minnan Normal University, Zhangzhou, 363000, China.

Translation initiation, which involves numerous protein factors and coordinated control steps, represents the most complicated process during eukaryotic translation. However, the roles of eukaryotic translation initiation factor (eIF) in filamentous fungi are not well clarified. In this study, we investigated the function of eIF2Bα in Aspergillus oryzae, an industrially important filamentous fungus.

Exposure to vanadium (V) occurs through the ingestion of contaminated water, polluted soil, V-containing foods and medications, and the toxicity and absorption during the small intestine phase after oral ingestion play crucial roles in the ultimate health hazards posed by V. In this study, the human colon adenocarcinoma (Caco-2) cells were selected as an intestinal absorption model to investigate the uptake and cytotoxicity of vanadyl sulfate (VOSO) and sodium orthovanadate (NaVO). Our results confirmed the cytotoxic effects of V(IV) and V(V) and revealed a greater toxicity of V(IV) than V(V) towards Caco-2 cells.

Puerarin pretreatment provides protection against myocardial ischemia/reperfusion injury via inhibiting excessive autophagy and apoptosis by modulation of HES1.

Sci Rep

January 2025

Department of Cardiovascular Surgery, The First Affiliated Hospital, Jiangxi Medical College, Nanchang University, 17 Yongwai Road, Nanchang, 330006, Jiangxi, China.

The study aimed to elucidate the underlying pharmacological mechanism of the traditional Chinese medicine Pue in ameliorating myocardial ischemia-reperfusion injury (MIRI), a critical clinical challenge exacerbated by reperfusion therapy. In vivo MIRI and in vitro anoxia/reoxygenation (A/R) models were constructed. The results demonstrated that Pue pretreatment effectively alleviated MIRI, as manifested by diminishing the levels of serum CK-MB and LDH, mitigating the extent of myocardial infarction and enhancing cardiac functionality.
