5 methylcytosine/inflammation

Ten-eleven translocation methylcytosine dioxygenase converts 5-methylcytosine in DNA to 5-hydroxymethylcytosine, which plays an important role in gene transcription. Although 5-hydroxymethylcytosine is enriched in mammalian neurons, its regulatory function in nociceptive information processing is

This study aims to elucidate the level of DNA methylation in urothelial carcinomas (UCs) using 5-methylcytosine (5-MeC) immunohistochemistry (IHC). We examined the relationship among 5-MeC levels, DNA (cytosine-5)-methyltransferase 1 (DNMT1) immunostaining levels, and clinicopathologic features.

Inflammation-mediated reactive molecules can result in an array of oxidized and halogenated DNA-damage products, including 5-chlorocytosine ((Cl)C). Previous studies have shown that (Cl)C can mimic 5-methylcytosine ((m)C) and act as a fraudulent epigenetic signal, promoting the methylation of

Cytokines produced in the tumour microenvironment exert an important role in cancer pathogenesis and in the inhibition of disease progression. Cancer of the cartilage is termed metastatic chondrosarcoma; however, the signaling events resulting in mesenchymal cell transformation to sarcoma have yet

Although the lung is one of the target organs at risk for cancer induction from exposure to heavy ions found in space, information is insufficient on cellular/molecular responses linked to increased cancer risk. Knowledge of such events may aid in the development of new preventive measures.

OBJECTIVE To investigate the biological effects of titanium ((48)Ti, one of the important heavy ions found in space) in the liver of exposed-mice. METHODS We gave adult male CBA/CaJ mice a whole-body exposure to a total dose of 0, 0.1, 0.25 or 0.5 Gy of (48)Ti ions. The liver was collected at 1

In the experiment with guinea pigs at contact sialoadenitis reproduction (karragenine inflammation of soft tissues of the oral cavity) it was established that in DNA of salivary glands cells and the neighbouring tissues the content of 5-methylcytosine was decreased, it being normalized at "Triovit"

Exposure of airborne particulate matter (PM) with an aerodynamic diameter less than 2.5 μm (PM_2.5) is epidemiologically associated with lung dysfunction and respiratory symptoms, including pulmonary fibrosis. However, whether epigenetic mechanisms are involved in PM_2.5-induced

Decidual macrophages secrete proteases that activate protease-activated receptor 1 (PAR-1). We hypothesized that activation of the inflammatory response by bacteria is amplified by proteases, initiating labor. In addition, we hypothesized that commensal bacteria trigger an inflammatory response by

Dental pulp inflammation is a pathological process characterized by local lesions in dental pulp and the accumulation of inflammatory mediators. DNA methylation of cytosine residues is a key epigenetic modification that is essential for gene transcription, and plays pivotal roles in inflammatory

Colorectal cancer (CRC) is a major health challenge worldwide. Factors thought to be important in CRC etiology include diet, microbiome, exercise, obesity, a history of colon inflammation and family history. Interventions, including the use of non-steroidal anti-Inflammatory drugs (NSAIDs) and

Nitric oxide (NO(.)), which is generated under chronic inflammatory conditions that predispose individuals to cancer, has paradoxical effects. NO(.) can activate p53, which can result in anti-carcinogenic effects, or it can be mutagenic and increase cancer risk. We explored the mechanisms by which

Dental pulp inflammation is a bacterially driven inflammation process characterized by the local accumulation of cytokines/chemokines that participate in destructive processes in the pulp. Multiple mechanisms are involved in dental pulp inflammation, including epigenetic events, such as DNA

OBJECTIVE Previous studies have suggested that dietary folic acid (FA) can protect against certain types of cancers. However, the findings have varied, and the mechanisms by which FA exerts chemopreventive effects remain to be clarified. We examined the effects of FA supplementation on DNA

BACKGROUND A characteristic feature of malignant cells, such as colorectal cancer cells, is a profound decrease in the level of 5-hydroxymethylcytosine, a product of 5-methylcytosine oxidation by TET enzymes. Recent studies showed that ascorbate may upregulate the activity of TET enzymes in cultured
