The level of cytokine expression was measured in human coronary artery (HCAEC) and internal thoracic artery (HITAEC) endothelial cells exposed to 500 ng/ml alkylating mutagen mitomycin C (MMC) and 5 μM atorvastatin. It was found that treatment of MMC-exposed HCAEC with atorvastatin decreased secretion of macrophage migration inhibitory factor (MIF), IL-8, and IL8 gene expression, but increased the expression of SERPINE1 gene encoding the PAI-1 protein. In atorvastatin-treated HITAEC, the concentration of MIF protein and the expression of the IL8 and SERPINE1 genes were reduced.

HMG-CoA reductase inhibitors (statins) are widely used in the therapy of atherosclerosis and have a number of pleiotropic effects, including DNA repair regulation. We studied the cytogenetic damage and the expression of DNA repair genes (, , and ) in human coronary artery (HCAEC) and internal thoracic artery endothelial cells (HITAEC) in vitro exposed to mitomycin C (MMC) (positive control), MMC and atorvastatin (MMC+Atv), MMC followed by atorvastatin treatment (MMC/Atv) and 0.9% NaCl (negative control).

It was shown, that genotoxic stress can trigger endothelial disfunction and atherosclerosis, but the molecular genetic mechanisms of this process are poorly investigated. At the same time, inflammation also plays the important role in atherogenesis. This study aimed access of inflammatory marker expression in the endothelial cells exposed to alkylating mutagen mitomycin C (MMC).

Atherosclerosis is a leading cause of cardiovascular morbidity and mortality worldwide. Endothelial disfunction underlying the atherogenesis can be triggered by genotoxic stress in endothelial cells. In the presented research whole transcriptome sequencing (RNA-seq) of human coronary artery (HCAEC) and internal thoracic artery (HITAEC) endothelial cells in vitro exposed to 500 ng/mL mitomycin C (treatment group) or 0.

The development and pathogenesis of atherosclerosis are significantly influenced by lifestyle, particularly nutrition. The modern level of science and technology development promote personalized nutrition as an efficient preventive measure against atherosclerosis. In this survey, the factors were revealed that contribute to the formation of an individual approach to nutrition: genetic characteristics, the state of the microbiota of the gastrointestinal tract (GIT) and environmental factors (diets, bioactive components, cardioprotectors, etc.

DNA-methyltransferases catalyze DNA methylation in the CpG sites, which play an important role in the maintenance of genome stability. The association between DNA methylation and genotoxic stress resulting in the action of various clastogens has been shown. Genotoxic stress is one of the triggers of endothelial dysfunction.

More than two billion people around the world are overweight or obese. Even in apparently healthy people, obesity has a potent effect on their quality of life. Experimental data indicate the role of infectious agents in systemic inflammation, revealing a correlation between the dietary habits of people with obesity and the level of systemic inflammation mediators, serum lipid concentration, and hormonal and immune status.

The expression of DNA repair (DDB1, ERCC4, ERCC5), leukocyte adhesion (VCAM1, ICAM1, SELE, SELP), endothelial mechanotransduction (KLF4), endothelial differentiation (PECAM1, CDH5, CD34, NOS3), endothelial-to-mesenchymal transition (SNAI1, SNAI2, TWIST1, GATA4, ZEB1, CDH2), scavenger receptors (LOX1, SCARF1, CD36, LDLR, VLDR), antioxidant system (PXDN, CAT, SOD1) and transcription factor (HEY2) genes in primary human coronary (HCAEC) and internal thoracic (HITAEC) arteries endothelial cells exposed to alkylating mutagen mitomycin C (MMC) was studied at two time points - after 6 h of incubation with MMC and after 6 h of the genotoxic load followed by 24 h of incubation in pure culture medium using the quantitative PCR. Immediately after MMC exposure, in the exposed HCAEC and HITAEC a decreased expression of almost all studied genes was noted excepted SNAI, which demonstrated a 4-told increase in its expression compared to the unexposed control. Elimination of MMC from the cultures, an increased expression of the VCAM1, ICAM1, SELE, SNAI2, KLF4 genes and a decreased the mRNA level of the PECAM1, CDH5, CD34, ZEB1, CAT, PXDN genes were observed in both cell lines.

Background: Atherogenesis is mainly determined by endothelial dysfunction, lipid metabolism disorders and inflammation. The atherogenesis-related inflammatory process is a complex interaction between serum blood lipoproteins, inflammatory cells, endothelial and smooth muscle cells and extracellular matrix; the role of chronic inflammation in atherogenesis was proposed.

Material And Methods: A pathogenetic role of polymorphism in NF-kB pathway genes in coronary artery disease and associated pathological conditions has been suggested in a case-control retrospective study.

Mitomycin C (MMC) is an alkylating chemotherapy drug that causes DNA crosslinking resulting in transcription arrest and apoptosis. DNA crosslinking is a critical damage to DNA that can be caused not only by MMC and other antitumor drugs, but also by various environmental and anthropogenic endo- and exogenous agents. Mammalian cells exposed to alkylating mutagens are characterized by severe genotoxic stress.

The aim of the study was to identify the features of the genetic structure of myocardial infarction (MI) susceptibility depending on age ("early MI" denoting individuals who had the first MI before the age of 60 years, and "late MI" the group of patients with the first "MI after 60 years"). A total of 355 patients were examined (n = 121 early MI and n = 234 late MI) and 285 residents of the Siberian region (as a control group). Genotyping of 58 single nucleotide variants (SNPs) was performed using mass spectrometry using the Agena (ex Sequenom) MassARRAY® System.
