2023年10月12日,美国加州大学伯克利分校植物与微生物生物学系Ben P. Williams团队在《Genome Biology》杂志上发表题为“Dynamic DNA methylation turnover in gene bodies is associated with enhanced gene expression plasticity in plants”的研究论文,该研究以模式植物拟南芥为研究对象,通过WGBS、EM-seq、RNA-seq等多...
In our study, we investigated population-specific gene expression and DNA methylation in AAs, an admixed population. We found HypoM genes, which indicate increased gene expression, are enriched for “system development” and “response to drug.” HypoM, or demethylation, may be a better predicto...
DNA Methylation and Gene Expressiondoi:10.1002/wsbm.64Methylation of cytosines is the key epigenetic modification of DNA in eukaryotes and is associated with a repressed chromatin state and inhibition of gene expression. The methylation pattern in mammalian genomes is bimodal, with most of the ...

To determine whether variations in DNA methylation exist among PS, TS, and SS, we first used qRT-PCR to globally scrutinize the expression levels of genes involved in DNA methylation. We focused on the DNA methylation genesPtrMET1A/B,PtrDRM1/2-A-C, PtrCMT3-A-C, andPtrDDM1-A/Band the...
