Aging induces progressive structural and functional changes in the heart and vasculature, increasing the risk of cardiovascular diseases (CVDs) such as coronary artery disease, heart failure, stroke, and atherosclerosis. Autophagy is essential for maintaining cardiovascular homeostasis, and its age-associated decline contributes to cardiac and vascular dysfunction in aging-related CVDs.

At CD BioSciences, we provide specialized analysis services using in vitro and in vivo models to assess age-related alterations in autophagy and their effects on cardiac structure and function in aging-related CVDs.
How Do We Analyze the Role of Autophagy in Aging-Related Cardiovascular Diseases?
Analysis of autophagy in age-related cardiovascular changes
Using advanced histological, molecular, and ultrastructural approaches, we assess autophagy flux and lysosomal function in aging cardiac tissues and disease models. Immunohistochemical analysis of key autophagy markers, including LC3B and p62/SQSTM1, enables evaluation of autophagosome formation and turnover, while electron microscopy supports the characterization of autophagosomes and autolysosomes at the ultrastructural level. By integrating quantitative marker analysis with morphological and functional assessments, we evaluate how autophagy dysfunction correlates with cardiac and vascular remodeling, endothelial dysfunction, fibrosis, apoptosis, and the progression of aging-related CVDs.
Analysis of autophagy signaling pathways in aging-related CVD
We provide comprehensive analysis services to investigate key signaling pathways regulating autophagy in aging-related CVDs, including the mechanistic target of rapamycin (mTOR) pathway, sirtuin signaling pathways, insulin-like growth factor-1 (IGF-1) signaling, and AMP-activated protein kinase (AMPK) pathway. Using gene expression profiling techniques such as RNA sequencing, we assess alterations in autophagy-related genes and signaling molecules. Our services enable clients to examine the molecular mechanisms of autophagy dysregulation and its impact on both cardiac and vascular structure and function during aging.
Preclinical Evaluation of Anti-Aging Therapeutics in Cardiovascular Diseases
We provide preclinical evaluation services to identify and characterize drug candidates that restore autophagic function in aging-related CVDs. Through high-throughput screening platforms and mechanistic assays, we assess compound effects on autophagy flux, signaling pathway modulation, cellular senescence markers, and cardiovascular functional readouts.
Our integrated evaluation services include efficacy assessment in aging models, as well as safety and toxicity profiling, enabling comprehensive preclinical support for the development of autophagy-targeted anti-aging therapeutics for CVDs.
CD BioSciences offers comprehensive analysis services to help clients study the role of autophagy in aging-related CVDs. Our commitment to reliable technologies, customized study design, expert scientific team, timely delivery, and comprehensive reporting sets us apart as a trusted partner in autophagy research.
