Aging is a significant risk factor for various conditions, including neurodegeneration, cardiovascular disease, and type 2 diabetes. The accumulation of reactive oxygen species (ROS) and a decline in antioxidant defense are mechanisms that are widely acknowledged as causing the acceleration of both aging and the onset of age-related diseases. To promote longevity and reduce the risk of the development of aging-related disorders, it is essential to prevent or minimize oxidative stress and enhance antioxidant defense. It has been shown that Anoectochilus burmannicus (AB), a jewel orchid rich in phenolic compounds, can impact various biological activities associated with aging prevention. These activities include antioxidant, anti-inflammation, anti-insulin resistance, and anti-obesity effects. The aim of this study was to explore whether AB extract (ABE) could serve as an anti-aging agent using a Sod1-deficient Drosophila model, which accelerates the process of aging through ROS production. The results demonstrated that ABE, at a concentration of 2.5 mg/mL, significantly extended the lifespan of the flies and helped maintain their locomotor activity as they aged. ABE also reduced the age-related accumulation of damaged proteins in the muscle of the flies by inhibiting the expression of Gstd1, a genetic marker for oxidative stress. This finding agrees with those from in vitro experiments, which have shown the potential for ABE to reduce the production of ROS induced by H2O2 in myoblasts. ABE has been shown to attenuate insulin resistance, an age-related disorder, by inhibiting the pro-inflammatory cytokine TNF-α, which in turn increased insulin-stimulated glucose uptake in adipocytes. These findings suggest a promising role of ABE as an ingredient in functional foods or nutraceuticals aimed at promoting health, preventing oxidative stress, and potentially managing age-associated diseases.

Seed aging is a complicated process influenced by environmental conditions, impacting biochemical processes in seeds and causing deterioration that results in reduced viability and vigor. In this study, we investigated the seed aging process of ridge gourd, which is one of the most exported commercial seeds in Thailand using sequential window acquisition of all theoretical fragment ion spectra mass spectrometry. A total of 855 proteins were identified among the two groups (0 d/15 d and 0 d/30 d). The Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses of differentially expressed proteins revealed that in ridge gourd seeds, the aging process altered the abundance of proteins related to the oxidative stress response, nutrient reservoir, and metabolism pathway. The most identified DEPs were mitochondrial proteins, ubiquitin-proteasome system proteins, ribosomal proteins, carbohydrate metabolism-related proteins, and stress response-related proteins. This study also presented the involvement of aconitase and glutathione pathway-associated enzymes in seed aging, with aconitase and total glutathione being determined as possible suggestive biomarkers for aged ridge gourd seeds. This acquired knowledge has the potential to considerably improve growing methods and seed preservation techniques, enhancing seed storage and maintenance.
