Abstract

As an important epigenetic modification DNA methylation is catalyzed by DNA methylation transferases (DNMTs) and occurs mainly in CpG islands. DNA methylation plays an important role in regulates gene expression, cell differentiation, genetic imprinting and tumor therapy. Retinoic acid-binding proteins (RAC) is vital for the absorption, transport, metabolism and maintenance of homeostasis of retinoic acid, which in turn regulates the differentiation and proliferation of cells by regulating the transcription of many target genes, therefore, these proteins influence differentiation and proliferation of adipocytes and muscle fibroblasts. Thus, cellular retinoic acid binding protein 2 (CRABP2) may be a candidate gene which affects beef quality, yield and fat deposition. The aim of this study was to evaluate the expression and the methylation pattern on the differentially methylated region (DMR) of the promoter of CRABP2. The DNA methylation pattern was tested by bisulfite sequencing polymerase chain reaction (BSP), the quantitative real-time PCR (qPCR) was used to analysis the expression of CRABP2 gene. The results showed that the DNA methylation level was higher in purebred cattle breed than that in hybrid cattle breeds which was ...Continue Reading

Cancer Epigenetics & Metabolism (Keystone)

Epigenetic changes are present and dysregulated in many cancers, including DNA methylation, non-coding RNA segments and post-translational protein modifications. The epigenetic changes may or may not provide advantages for the cancer cells. This feed focuses on the relationship between cell metabolism, epigenetics and tumor differentiation.
