Selective Advantage of Mutant Stem Cells in Human Clonal Hematopoiesis Associated with Attenuated Response to Inflammation and Aging

Selective Advantage of Clonal Hematopoietic Mutant Stem Cells in Aging and Inflammatory Responses Background and Research Motivation Clonal Hematopoiesis (CH) is an aging-related phenomenon in the hematopoietic system, where hematopoietic stem cells (HSCs) acquire specific somatic mutations and undergo expansion, causing a particular mutated cell l...

Role of SDHAF1 in Aging Hematopoietic Stem Cells: Enhancing Metabolic Resilience through Mitochondrial ATP Production

Role of SDHAF1 in Aging Hematopoietic Stem Cells: Enhancing Metabolic Resilience through Mitochondrial ATP Production

Research Background and Objective As individuals age, hematopoietic stem cells (HSCs) progressively accumulate in the bone marrow, exhibiting metabolic resilience under various stress conditions. This metabolic resilience provides an aging advantage for HSCs, enabling them to maintain cell viability even under low metabolic conditions. Although agi...

Aging-induced tRNAglu-derived fragment impairs glutamate biosynthesis by targeting mitochondrial translation-dependent cristae organization

Aging-induced trnaGlu-derived fragments disrupt glutamate biosynthesis by targeting mitochondrial translation-dependent cristae organization Academic Background Mitochondrial cristae are inward protrusions of the inner mitochondrial membrane that undergo significant morphological changes during aging. However, the molecular mechanisms leading to th...

Effects of Chronic Hypertension on the Energy Metabolism of Cerebral Cortex Mitochondria in Normotensive and Spontaneously Hypertensive Rats During Aging

Effects of Chronic Hypertension on Mitochondrial Energy Metabolism in the Cerebral Cortex of Normal and Spontaneously Hypertensive Rats Background Introduction Chronic hypertension has destructive structural and functional consequences for cerebral vessels and brain parenchyma. Hypertension impairs cerebrovascular autoregulation (Ferrari & Villa, 2...

Compensation or Preservation? Different Roles of Functional Lateralization in Speech Perception of Older Non-Musicians and Musicians

The Impact of Music Training on Language Perception in Older Adults Under Global Aging Challenges Research Background As global population aging accelerates, the decline in language perception ability of older adults in noisy environments has become a notable issue. Older adults, even with normal hearing, often encounter the “cocktail party problem...

Microglia Undergo Sex-Dimorphic Transcriptional and Metabolic Rewiring During Aging

The Role of Microglia in Neuroinflammation: Metabolic and Gender Differences in Aging Research Background Aging is a major risk factor for neurodegenerative diseases such as Alzheimer’s Disease (AD) and Parkinson’s Disease. Even healthy aging is accompanied by a decline in cognitive function. Previous research has indicated that microglia undergo s...

Research Review on Aging-Exacerbated Metabolic Dysfunction-Related Lipid Liver Diseases Academic Background As the aging population increases, metabolic diseases induced by aging are becoming a severe public health challenge. The liver, being the primary metabolic organ, requires special attention to its functional disorders during aging. Studies h...

Nature of Epigenetic Aging from a Single-Cell Perspective

Research on the Essence of Epigenetic Aging from a Single-Cell Perspective Research Background As biological research progresses, scientists have discovered that changes in DNA methylation (DNAm) constitute one of the most reliable predictors of age—known as the epigenetic clock. However, the mechanisms underlying what these clocks precisely measur...
