Aging Promotes Reactivation of the Barr Body at Distal Chromosome Regions

1. Academic Background: The Mysterious Link between X Chromosome Inactivation and Aging In mammals, females possess two X chromosomes while males have only one. To maintain gene dosage balance between the sexes, females undergo a process called X chromosome inactivation (XCI) early in development, in which one of the two X chromosomes is randomly s...

Gut Microbiota-Dependent Increase in Phenylacetic Acid Induces Endothelial Cell Senescence During Aging

Molecular Mechanisms of Gut Microbiota and Its Metabolites Mediating Endothelial Cell Senescence During Aging – Interpretation of Latest Results from Nature Aging I. Research Background and Significance Against the backdrop of a deeply aging human society, cardiovascular disease (CVD) has become one of the greatest health threats to the global elde...

Role of Recurrent Somatic Mutation and Progerin Expression in Early Vascular Aging of Chronic Kidney Disease

1. Academic Background and Research Rationale Chronic Kidney Disease (CKD) is a global public health challenge. Epidemiological data indicate that CKD affects approximately 10–12% of the world’s population, acting as a major driver of cardiovascular disease (CVD) mortality worldwide. CKD patients often display “Early Vascular Aging” (EVA) phenomena...

Adult Human Heart Extracellular Matrix Improves Human iPSC-CM Function via Mitochondrial and Metabolic Maturation

1. Academic Background Cardiovascular diseases, especially myocardial infarction (MI), are among the leading causes of death and disability worldwide. After a myocardial infarction, up to one billion cardiomyocytes (CM) can be lost in just a few hours. However, adult myocardial tissue itself has extremely low regenerative capacity, which means the ...

Neonatal Apical Resection Preserves the Proliferative Capacity of Cardiomyocytes Throughout the Left Ventricle

I. Academic Background: The Cardiac Mystery Facing Regenerative Medicine Cardiovascular diseases, especially myocardial infarction (MI), are among the leading causes of death and disability worldwide due to heart damage. However, the adult mammalian heart has long been regarded as having essentially lost its endogenous regenerative ability, with th...

Development and Validation of a Proteomic Signature of Healthspan

1. Academic Background: From Lifespan Extension to the Enhancement of Healthspan With the improvement of global medical and socioeconomic standards since the 20th century, overall human lifespan has significantly increased, especially in developing countries. However, healthspan—the number of years an individual lives in a state of complete health,...

METTL3 Mediates Atheroprone Flow–Induced Glycolysis in Endothelial Cells

1. Research Background Atherosclerosis is the primary pathological basis of cardiovascular diseases, closely associated with endothelial cell (EC) dysfunction. Hemodynamic factors play a critical role in the regional selectivity of atherosclerosis: oscillatory shear stress (OS) (e.g., at vascular bifurcations) promotes plaque formation, while pulsa...

Modulation of Bone Marrow Haematopoietic Stem Cell Activity as a Therapeutic Strategy After Myocardial Infarction: A Preclinical Study

Academic Background Myocardial Infarction (MI) is one of the major global health concerns. Although myeloid cells in the bone marrow (BM) are crucial for tissue repair after MI, excessive myelopoiesis can exacerbate scarring and impair cardiac function. Hematopoietic stem cells (HSCs) in the bone marrow possess unique regenerative capabilities, ena...

Sugarcane Wax-Based Solid Lipid Nanoparticles as an Atorvastatin Carrier: Characterization and In Vivo Evaluation of Antihyperlipidemic Activity in Rats

Academic Background Cardiovascular diseases, particularly atherosclerosis, are one of the leading causes of death globally. Elevated cholesterol levels are a major risk factor for atherosclerosis. Atorvastatin (ATV) is a widely used cholesterol-lowering drug, but its oral bioavailability is low, primarily due to first-pass metabolism. To improve th...

An Electromechanical Model-Based Study on the Dosage Effects of Ranolazine in Treating Failing HCM Cardiomyocyte

Hypertrophic Cardiomyopathy (HCM) is a common inherited heart disease, affecting approximately 1 in 500 people globally. The primary characteristic of HCM is asymmetric hypertrophy of the myocardium. In its early stages, it may manifest as hyperdynamic contraction of the left ventricle (LV). However, as the disease progresses, patients may develop ...
