Principal Component-Based Clinical Aging Clocks Identify Signatures of Healthy Aging and Targets for Clinical Intervention

Clinical Aging Clock Based on Principal Components Reveals Characteristics of Healthy Aging and Targets for Clinical Interventions Background of the Study As the population ages, promoting healthy aging and slowing down biological aging has become an important issue. To accurately predict all-cause mortality and obtain feasible measures to promote ...

GDF1 Ameliorates Cognitive Impairment Induced by Hearing Loss

Improvement of Cognitive Impairment Induced by Hearing Loss Background Alzheimer’s Disease (AD) is a common dementia characterized by extracellular amyloid plaques formed by aggregation of amyloid-β (Aβ) and intracellular neurofibrillary tangles formed by aggregated tau protein. Epidemiological studies indicate a close correlation between hearing l...

A mild increase in nutrient signaling to mTORC1 in mice leads to parenchymal damage, myeloid inflammation, and shortened lifespan

Research on the Impact of Nutritional Signals on the Lifespan of Mice Background and Motivation In recent years, the intensification of global aging has posed unprecedented challenges to medicine, socio-economics, and philosophy. By 2050, the global population aged 65 and above is expected to grow from 5% at the beginning of the 20th century to 17%...

DDX5 Inhibits Hyaline Cartilage Fibrosis and Degradation in Osteoarthritis via Alternative Splicing and G-Quadruplex Unwinding

The Novel Mechanism of DDX5 in Inhibiting Hyaline Cartilage Fibrosis and Degradation in Osteoarthritis Background Osteoarthritis (OA) is a chronic degenerative disease characterized mainly by the degradation, degeneration, and osteophyte formation of joint cartilage. Hyaline cartilage fibrosis is often considered the end-stage lesion of OA, leading...

Inhibition of S6K Lowers Age-Related Inflammation and Increases Lifespan Through the Endolysosomal System

Inhibition of S6K Reduces Age-Related Inflammation and Extends Lifespan through the Endosomal-Lysosomal System Research Background and Problem Description As organisms age, chronic low-grade inflammation (inflammaging) and declined immune function (immunosenescence) become important pathological foundations of many diseases in the elderly, such as ...

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...

Plasma Membrane Damage Limits Replicative Lifespan in Yeast and Induces Premature Senescence in Human Fibroblasts

Scientific Research Report: Plasma Membrane Damage Limits Yeast Replicative Lifespan and Induces Premature Senescence in Human Fibroblasts Background and Research Motivation Plasma Membrane Damage (PMD) is a phenomenon experienced by all cell types in response to environmental disturbances and spontaneous cellular activities. Previous studies have ...

Menopausal Hormone Therapy and Breast Cancer Risk: A Population-Based Cohort Study of 1.3 Million Women in Norway

Epidemiological Study on Menopausal Hormone Therapy and Breast Cancer Risk Introduction This study aims to explore the relationship between Menopausal Hormone Therapy (HT) and the risk of Breast Cancer (BC). While HT can relieve menopausal symptoms in women (such as hot flashes, fatigue, and urinary pain), it may also pose other health risks like a...

Oncogenic KRAS-dependent Stromal Interleukin-33 Directs the Pancreatic Microenvironment to Promote Tumor Growth

The Role of IL-33 in Promoting Tumor Growth in Pancreatic Cancer Tissue and its Potential as a Therapeutic Target Background Introduction Pancreatic Cancer (PDA) is one of the most lethal malignancies worldwide, characterized by rapid clinical progression and poor treatment responses, with a five-year survival rate of only 13%. In the United States...
