TET3‐Mediated m5C Modification of CCAT2 Accelerates Cardiac Microvascular Endothelial Cell Damage in Acute Coronary Syndrome

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Acute coronary syndrome (ACS) is a clinical syndrome involving myocardial ischemia. This study aimed to elucidate the mechanism of TET3 in ACS‐induced CMEC damage, thereby identifying a new target for ACS treatment. The expression of TET3 in ACS patients and healthy subjects was analyzed.

Circ_0006174 Drives Triple Negative Breast Cancer Progression and Immune Escape Through Regulating miR‐3139/PD‐L1 Axis

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) is characterized as an aggressive malignancy with limited therapeutic options. The circular RNA circ_0006174 has been implicated in oncogenic processes across various cancers; however, its specific role in the pathogenesis of TNBC remains unclear.

Aging and DNA Methylation

Current Chemical Biology, 2009
Abstract: Human longevity is influenced by both inherited and environmental factors. Alterations in gene function that are related to inherited genetic mutations and polymorphisms can explain some features of aging and age-related diseases. However, in addition to inherited genetic factors, aging is influenced by the gradual accumulation of molecular ...

DNA methylation and cellular ageing

Mutation Research/DNAging, 1991
Methylated cytosine (m5C) in DNA appears to be an important modulator of the expression of some genes. There are several lines of evidence that gradual loss of m5C is relevant to in vitro cellular ageing: m5C loss occurs during cell culture; m5C loss is detectable at an early stage of culture; m5C loss appears to be related to cell division not just ...

Exponential Dynamics of DNA Methylation with Age

Journal of Theoretical Biology, 2023
The association of DNA methylation with age has been extensively studied. Previous work has investigated the trajectories of methylation with age, and developed predictive biomarkers of age. However, we still have a limited understanding of the functional form of methylation-age dynamics.

DNA methylation, mitochondria, and programmed aging

Biochemistry (Moscow), 2015
DNA methylation is a key epigenetic process involved in the regulation of nuclear gene expression. Progress in the study of genomic DNA methylation led to the precise identification of methylation sites reflecting biological age of cells and tissues. However, the functional significance of mitochondrial DNA (mtDNA) methylation remains unknown.

DNA methylation in aging of mice

Mechanisms of Ageing and Development, 1987
Methylation of cytidine residues of DNA appears to be involved in the control of gene expression; therefore, hypomethylation of the DNA can be considered to be an active rather than a passive process. Previous studies of mammalian DNA methylation during aging have produced an assortment of results. In this study, we have examined the change in DNA base
