Although the interspecies hybridization of bovids, such as cattle-yak (Bos taurus x Bos grunniens), has heterosis benefits, the infertility of hybrid males affects the maintenance of dominant traits in subsequent generations. To achieve reproductive capacity, male germ cell development requires coordinated changes in gene expression, including DNA methylation and generalized histone modifications. Although gene expression-related mechanisms underlying hybrid male sterility have been investigated recently, information on the cell types and stage-specific controls remains limited. Here, we used immunohistochem. and image analyzes to evaluate the 5-methylcytosine (5MC) and acetyl-histone H3 Lys9 (AcK9) expression in all spermatogonia and testicular somatic cell types to determine their roles in cattle-yak spermatogenesis. Testicular tissues from yak (1-3 years old) and backcrossed hybrids (2 years old) were used. In yak, the AcK9 expression levels increased in all cell types during maturation, but the 5MC expression levels did not change until reaching 3 years when they increased in all testicular cell types, except spermatogonia. Cattle-yak hybrids showed higher 5MC expression levels and different AcK9 expression levels in all cell types compared to the same-aged yak. These results suggested that both gene modulation by AcK9 and constant levels of DNA methylation are required for spermatogenesis during maturation in yak. Therefore, inappropriate expression levels of both AcK9 and DNA methylation might be the major factors for disruption of normal germ cell development in cattle-yak. Addnl., various modulations occurred depending on the cell type. Further experiments are needed to identify the stage-specific gene expression modulations in each cell type in yak and cattle-yak to potentially solve the infertility issue in crossbreeding.

COA of Formula: C5H7N3O, 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).

Parrilla-Doblas, J. T.;Morales-Ruiz, T.;Ariza, R. R.;Martinez-Macias, M. I.;Roldan-Arjona, T. research published 《 The C-terminal domain of Arabidopsis ROS1 DNA demethylase interacts with histone H3 and is required for DNA binding and catalytic activity》, the research content is summarized as follows. Active DNA demethylation plays an important role in controlling methylation patterns in eukaryotes. In plants, the DEMETER-LIKE (DML) family of 5-methylcytosine DNA glycosylases initiates DNA demethylation through a base excision repair pathway. However, it is poorly understood how these DNA demethylases are recruited to their target loci and the role that histone marks play in this process. Arabidopsis REPRESSOR OF SILENCING 1 (ROS1) is a representative enzyme of the DML family, whose members are uniquely characterized by a basic amino-terminal domain mediating nonspecific binding to DNA, a discontinuous catalytic domain, and a conserved carboxy-terminal domain of unknown function. Here, we show that ROS1 interacts with the N-terminal tail of H3 through its C-terminal domain. Importantly, phosphorylation at H3 Ser28, but not Ser10, abrogates ROS1 interaction with H3. Conserved residues at the C-terminal domain are not only required for H3 interaction, but also for efficient DNA binding and catalytic activity. Our findings suggest that the C-terminal domain of ROS1 may function as a histone reader module involved in recruitment of the DNA demethylase activity to specific genomic regions.

In this paper, we report the catalytic activity of a series of ruthenium (II) complexes containing phosphorus-nitrogen bidentated (P-N) ligands in the hydrogenation of furfural via hydrogen transfer reaction using two hydrogen donor sources: 2-propanol in basic medium and formic acid under mild conditions. The results showed that all the ruthenium complexes studied are catalytically active in the hydrogenation of furfural by hydrogen transfer reaction; they showed 100% conversion with both hydrogen sources. However, selectivities towards the formation of furfuryl alc. were better when formic acid was used. It was also found that the reaction studied in a basic medium competes with the Cannizzaro reaction, obtaining furfuryl alc. and furoic acid in a 70/30 ratio; on the other hand, using formic acid as the hydrogen source yields furfuryl alc. with 100% selectivity. Although formic acid can be used as a hydrogen source successfully. The optimal substrate/acid ratio was found to be 1:1, as a higher concentration of formic acid can cause catalyst decomposition The yielded products, furfuryl alc. and furoic acid, obtained from renewable sources, have multiple applications in the organic chem. industry, replacing or complementing similar fossil-derived products.

The study of metabolomics and disease has enabled the discovery of new risk factors, diagnostic markers, and drug targets. For neurol. and psychiatric phenotypes, the cerebrospinal fluid (CSF) is of particular importance. However, the CSF metabolome is difficult to study on a large scale due to the relative complexity of the procedure needed to collect the fluid. Here, we present a metabolome-wide association study (MWAS), which uses genetic and metabolomic data to impute metabolites into large samples with genome-wide association summary statistics. We conduct a metabolome-wide, genome-wide association anal. with 338 CSF metabolites, identifying 16 genotype-metabolite associations (metabolite quant. trait loci, or mQTLs). We then build prediction models for all available CSF metabolites and test for associations with 27 neurol. and psychiatric phenotypes, identifying 19 significant CSF metabolite-phenotype associations Our results demonstrate the feasibility of MWAS to study omic data in scarce sample types.

Orotic acid has been found to be associated with several diseases known as phosphoenolpyruvate carboxykinase deficiency 1, cytosolic and hyperornithinemia-hyperammonemia-homocitrullinuria; orotic acid has also been linked to several inborn metabolic disorders including n-acetylglutamate synthetase deficiency, lysinuric protein intolerance, and ornithine transcarbamylase deficiency.
Orotic acid appears as white crystals or crystalline powder.
Orotic acid is a pyrimidinemonocarboxylic acid that is uracil bearing a carboxy substituent at position C-6. It has a role as a metabolite, an Escherichia coli metabolite and a mouse metabolite. It derives from a uracil. It is a conjugate acid of an orotate., 65-86-1.

Pankratova, E. V.;Portseva, T. N.;Makarova, A. A.;Ilyin, Yu. V.;Stepchenko, A. G.;Georgieva, S. G. research published 《 Glycogen synthase kinase 3 Inhibitor, CHIR, Suppress Transcription of Tissue Specific POU2F1 Isoform in Burkitt Namalwa Lymphoma Cells》, the research content is summarized as follows. POU2F1 (Oct-1) is a transcription factor, the overexpression of which is found in many human malignant tumors; a significant increase in its level in cells determines the malignant potential of the tumor. POU2F1 is represented in cells by several isoforms that are transcribed from alternative promoters. In Burkitt’s B-cell lymphoma Namalwa, the concentration of tissue-specific isoform Oct-1L is several times higher than in normal B cells. We tested the potential to inhibit the transcription of individual Oct-1 isoforms using the GSK3 kinase inhibitor CHIR, an aminopyrimidine derivatives We have shown that CHIR specifically affects the expression of the tissue-specific isoform Oct-1L, significantly reducing the level of mRNA and Oct-1L protein. However, CHIR does not change the amount of mRNA and protein of the ubiquitous isoform Oct-1A in Namalwa tumor cells. The results obtained show that it is possible to develop a system for selective inhibition of Oct-1 transcription factor isoforms in human cells to suppress drug resistance of tumor cells with a high POU2F1 content.
