Vedunova1 New Epigenetic Markers of Age-Dependent Changes in the Cardiovascular System 1Institute of Biology and Biomedicine, Lobachevsky State University of Nizhny Novgorod, Nizhny Novgorod, 603022 Russia2Clinical Hospital Number 38, Nizhny Novgorod, 603000 Russia *spring_dusk@mail.ru Received - 2024-05-17; Revised - 2024-07-09; Accepted - 2024-07-12 Cardiovascular diseases remain a predominant global cause of mortality, with a noteworthy rise in the risk of morbidity with advancing age. Besides, it accompanied by a phenomenon of disease rejuvenation in the circulatory system. Currently, epigenetic modifications play a key role in the genesis of cardiovascular diseases (CVD), influencing the complex interaction between genotype and phenotype variability. Consequently, delving into the realm of epigenetic markers offers a promising avenue to unravel the molecular underpinnings of cardiovascular disease pathogenesis. This study endeavors to pinpoint epigenetic markers intricately linked with age-related transformations in the cardiovascular system. The study revealed a robust correlation with age for two cardiological parameters: R wave tension in the augmented left arm lead (RaVL) and carotid-femoral pulse wave velocity (cfPWV). Moreover, these parameters exhibited a strong correlation with the DNA methylation level of 21 CpG-sites (CpGs) examined through the Illumina EPIC array. Notably, the majority of these identified CpG-sites are affiliated with genes involved in the development of pathologies of the cardiovascular system. ging, biological age, chronological age, coronary vascular diseases, CpGs, DNA methylation, electrocardiogram, sphygmography |
