On April 30, 2018, Briede, Jacob J.; Deferme, Lize; Wolters, Jarno E. J.; Claessen, Sandra M. H.; van den Beucken, Twan; Wagner, Richard J.; van Breda, Simone G.; Kleinjans, Jos C. S. published an article.Recommanded Product: 5-(Hydroxymethyl)pyrimidine-2,4(1H,3H)-dione The title of the article was A cross-omics approach to investigate temporal gene expression regulation by 5-hydroxymethylcytosine via TBH-derived oxidative stress showed involvement of different regulatory kinases. And the article contained the following:
Regulation of DNA methylation plays a crucial role in biol. processes and carcinogenesis. The formation of 5-hydroxymethylcytosine (5hmC) by oxidation of 5-methylcytosine (5mC) has been proposed as an intermediate of active demethylation. However, whether and how active demethylation is regulated by oxidative stress-related processes is not well understood. Here we investigated whether free oxygen radicals are capable of directly forming 5hmC and how this enhanced whole genome gene expression. We applied LC-MS/MS technol. for the anal. of 5mC, 5hmC, 5-formylcytosine (5fC) and 5-hydroxymethyluracyl (5hmU) in HepG2 cells exposed to hydroxyl- and Me radicals, formed by tert-Bu hydroperoxide (TBH) at multiple time points. We observed that TBH is able to induce a significant increase in 5hmC. A detailed evaluation of the hydroxymethylome using a combination of 5hmC-immunoprecipitation and microarrays resulted in the identification of highly dynamic modifications that appear to increase during prolonged oxidant exposure. Analyses of temporal gene expression changes in combination with network anal. revealed different subnetworks containing differentially expressed genes (DEGs) with differentially hydroxyl-methylated regions (DhMRs) in different regulatory kinases enriched with serine-threonine kinases. These serine-threonine kinases compromises MAPK14, RPSK6KA1, RIPK1, and PLK3 and were all previously identified as key-regulators in hepatocarcinogenesis and subject of study for chemotherapeutic interventions. The experimental process involved the reaction of 5-(Hydroxymethyl)pyrimidine-2,4(1H,3H)-dione(cas: 4433-40-3).Recommanded Product: 5-(Hydroxymethyl)pyrimidine-2,4(1H,3H)-dione
