پروتئین mbd2یکی از مهار کنند ه های ژن گاما گلوبین است.مکانیسم این مهار ناشناخته می باشد.با توجه به بیان ژن گاما گلوبین و پروتئین mbd2در رده سلولی k562،ما از این سلول ها به عنوان سیستم مدل استفاده کردیم.ابتدا پنج کلون لنتی ویروسی حاوی shrna-mbd2در سلول های 293tتست شدند،به این ترتیب که لنتی وکتور های plko.1به همراه shrna-mbd2به صورت گذرا به درون سلول های293tترانسفکت شدند و از اسکلت وکتور plko.1 ب...

Aberrant DNA methylation is a hallmark of various human disorders, indicating that the spatial and temporal regulation of methylation readers and modifiers is imperative for development and differentiation. In particular, the cross-regulation between 5-methylcytosine binders (MBD) and modifiers (Tet) has not been investigated. Here, we show that binding of Mecp2 and Mbd2 to DNA protects 5-methy...

OBJECTIVE The role of epigenetic modifications on leptin expression during the development of obesity has not been clearly determined. This study aimed to investigate changes in the expression of DNA methyltransferases (DNMTs) at the leptin promoter and their effect on gene transcription during the development of obesity. METHODS Using a high-fat diet (HFD)-induced obese (DIO) mouse model, we...

We report evidence of a detailed epigenetic modification of the leptin promoter and the effects of n-3 polyunsaturated fatty acids (n-3 PUFAs), which is closely associated with the leptin gene transcription in obesity. In the adipose tissue of diet induced obese (DIO) mice, methylation of the CpG island and the binding of methyl-CpG-binding domain protein 2 (MBD2) and DNA methyltransferases (DN...

DNA methylation plays critical roles in gene-silencing through chromatin modification. We reported previously that promoter-region CpG methylation repressed mouse delta-opioid receptor (mDOR) gene expression. In the current study, we demonstrated that the methylation of mDOR gene promoter is correlated with a repressive chromatin structure that has less HaeIII and MspI nuclear accessibility and...

Alternative RNA splicing (AS) regulates proteome diversity, including isoform-specific expression of several pluripotency genes. Here, we integrated global gene expression and proteomic analyses and identified a molecular signature suggesting a central role for AS in maintaining human pluripotent stem cell (hPSC) self-renewal. We demonstrate that the splicing factor SFRS2 is an OCT4 target gene...

Dendritic cells (DCs) direct CD4(+) T-cell differentiation into diverse helper (Th) subsets that are required for protection against varied infections. However, the mechanisms used by DCs to promote Th2 responses, which are important both for immunity to helminth infection and in allergic disease, are currently poorly understood. We demonstrate a key role for the protein methyl-CpG-binding doma...
