Roles of Chromatin insulators in gene regulation and diseases
With advances in genetic science, the dynamic structure of eukaryotic genome is considered as basis of gene expression regulation. Long-distance communication between regulatory elements and target promoters is critical and the mechanisms responsible for this connection are just starting to emerge. Chromatin insulators are key determinants of proper gene regulation and precise organization of c...
متن کاملRole of Brg1 in progression of esophageal squamous cell carcinoma
Objective(s): Epigenetic regulation of gene expression can be carried out through chromatin remodeling enzymes such as SWI/SNF. Brg1 also known as SMARCA4 is a catalytic subunit of SWI/SNF, which is necessary for MMPs expression. Matrix metalloproteinases (MMPs) are known as important player enzymes during tumor progression and metastasis. Aberrant epigenetic modification of chromatin should be...
متن کاملPotential roles of 5´ UTR and 3´ UTR regions in post-trans-criptional regulation of mouse Oct4 gene in BMSC and P19 cells
Objective(s):OCT4 is a transcription factor required for pluripotency during early embryogenesis and the maintenance of identity of embryonic stem cells and pluripotent cells. Therefore, the effective expression regulation of this gene is highly critical. UTR regions are of great significance to gene regulation. In this study, we aimed to investigate the potential regulatory role played by 5´UT...
متن کاملNuclear Architecture and Epigenetics of Lineage Choice
Differentiation is an epigenetic process which is installed by changes of transcriptional programs over successive cellular divisions. A number of studies have reported the effects of biochemical modifications of chromatin (DNA and chromatin proteins) on the regulation of transcription. Although, these studies are able to explain how transcription of a given gene is regulated (toward activation...
متن کاملBRG1-mediated chromatin remodeling regulates differentiation and gene expression of T helper cells.
During T helper cell differentiation, distinct programs of gene expression play a key role in defining the immune response to an environmental challenge. How chromatin remodeling events at the associated cytokine loci control differentiation is not known. We found that the ATP-dependent remodeling enzyme subunit BRG1 was required for T helper 2 (Th2) differentiation and Th2 cytokine transcripti...
