554-01-8, 5-Methylcytosine is a methylated form of the nucleobase cytosine occurring predominantly in cytosine-phosphate-guanine (CpG) islands that are produced by DNA methyltransferases and may regulate gene expression. Like cytosine, the DNA sequence containing 5-methylcytosine (5-mC) is able to be replicated without error and 5-mC can pair with guanine in double stranded DNA. However, DNA sequences containing a high local concentration of 5-mC may be less transcriptionally active than areas with higher ratios of unmodified cytosine.
5-Methylcytosine belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5-Methylcytosine exists as a solid, slightly soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 5-methylcytosine is primarily located in the cytoplasm. 5-Methylcytosine can be biosynthesized from cytosine. Outside of the human body, 5-methylcytosine can be found in tea. This makes 5-methylcytosine a potential biomarker for the consumption of this food product.
5-methylcytosine is a pyrimidine that is a derivative of cytosine, having a methyl group at the 5-position. It has a role as a human metabolite. It is a member of pyrimidines and a methylcytosine. It derives from a cytosine.
5-Methylcytosine is a nucleic acid that is found in the DNA and RNA of the cell. It is an important component of methylation, which is the process by which a methyl group is added to a molecule. This process can lead to cellular transformation, a process that can cause cancer. 5-Methylcytosine has also been shown as a molecular pathogenesis factor in infectious diseases such as HIV and herpes simplex virus type 1. The presence of 5-methylcytosine in nuclear DNA has been detected by analytical techniques such as gas chromatography/mass spectrometry (GC/MS). There are many analytical methods, including GC/MS, that can be used to detect 5-methylcytosine in cellular nuclei., Recommanded Product: 4-Amino-5-methylpyrimidin-2(1H)-one

Pyrimidine is a nitrogenous base similar to benzene (a six-membered ring) and includes cytosine, thymine, and uracil as bases used for DNA or RNA. 554-01-8, formula is C5H7N3O, Name is 4-Amino-5-methylpyrimidin-2(1H)-one. Pyrimidine also found in many synthetic compounds such as barbiturates and the HIV drug, zidovudine. Recommanded Product: 4-Amino-5-methylpyrimidin-2(1H)-one.

Boudra, Rafik;Woappi, Yvon;Wang, Diana;Xu, Shuyun;Wells, Michael;Schmults, Chrysalyne D.;Lian, Christine G.;Ramsey, Matthew R. research published 《 Regulation of 5-Hydroxymethylcytosine by TET2 Contributes to Squamous Cell Carcinoma Tumorigenesis》, the research content is summarized as follows. DNA methylation is a key regulatory event controlling a variety of physiol. processes and can have dramatic effects on gene transcription. Methylated cytosine (5-methylcytosine) can be oxidized by the TET family of enzymes to 5-hydroxymethylcytosine (5-hmC), a key intermediate in the demethylation cycle, and 5-hmC levels are reduced in malignancies such as acute myeloid leukemia and melanoma. We constructed a tissue microarray of human cutaneous squamous cell carcinoma tumors and found a global reduction in 5-hmC levels compared with that in the adjacent skin. Using a murine K14-CreER system, we have found that loss of Tet2 promotes carcinogen-induced squamous cell carcinoma and cooperates with loss of Tp53 to drive spontaneous squamous cell carcinoma tumors in epithelial tissues. Anal. of changes in 5-hmC and gene expression after loss of Tet2 in the epidermis revealed focal alterations in 5-hmC levels and an increase in hair follicle transient amplifying cell genes along with a reduction in epidermal differentiation genes. These results show a role for TET2 in epidermal lineage specification, consistent with reported roles for TET enzymes in controlling lineage commitment in hematopoietic stem cells and embryonic stem cells and establishing TET2 as a bone fide tumor suppressor in squamous cell carcinoma.
