Drosophila melanogaster has been used as a model system in biological studies for a long time, and those studies have contributed to elucidating the principal mechanisms of life and aging. The notable...
Tuning up an aged clock: Circadian clock regulation in metabolism and aging
2022
Circadian rhythms provide temporal variation of a broad range of behavioral and physiological functions, which is precisely controlled by the internal molecular gear, the circadian clock. However, circadian...
Mitochondrial cardiomyopathy and emerging therapeutics
2023
Genetic mitochondrial cardiomyopathy (MCM) is a myocardial condition characterized by abnormal cardiac structure and function secondary to genetic defects. Severity can vary from asymptomatic to severe...
Are you feeling comfortable? – Measuring clinical hormesis
2024
Hormesis is a biological phenomenon where exposure to a low dose of a stressor or toxin induces a beneficial adaptive response, whereas higher doses may have detrimental effects. The concept of hormesis...
Mechanistic insights of the anti-ageing dietary plant secondary metabolites vis-à-vis the modern hallmarks of ageing: Implications for developing novel anti-ageing foods
2024
Plant secondary metabolites (PSM) including polyphenols, alkaloids, and terpenes are diverse dietary influencers of human health that are also emerging as potent longevity modulators. However, the mechanistic...
Senescence in aging and disorders of the central nervous system
2019
Aging can be defined as the natural process of accumulating time during the life of an organism. Advancing age correlates with tissue dysfunction, including frailty, malignancies, immobility, and cognitive...
Caenorhabditis elegans as a model system for studying aging-associated neurodegenerative diseases
2020
Neurodegenerative diseases (NDs) are a heterogeneous group of aging-associated disorders characterized by the disruption of cellular proteostasis machinery and the misfolding of distinct protein species...
ELOVL2: Not just a biomarker of aging
2020
DNA methylation of the ELOVL2 (Elongation Of Very Long Chain Fatty Acids-Like 2) promoter is one of the most robust molecular biomarkers for chronological age, but whether ELOVL2 plays a functional...
Recent developments in the role of DNA damage response and understanding its implications for new therapeutic approaches in Alzheimer's disease
2023
The underlying molecular mechanisms associated with sporadic Alzheimer's disease (AD), a progressive neurodegenerative disease, are not yet fully understood. Adult neurons are post-mitotic cells that...
Targeting senescent cell clearance: An approach to delay aging and age-associated disorders
