Epigenetic silencing of myogenic gene program by Myb-binding protein 1a suppresses myogenesis.
Skeletal myogenesis involves highly coordinated steps that integrate developmental cues at the chromatin of muscle progenitors. Here, we identify Myb-binding protein 1a (Mybbp1a) as a novel negative regulator of muscle-specific gene expression and myoblast differentiation. The mode of action of Mybbp1a was linked to promoter regulation as illustrated by its interaction with MyoD at the genomic ...
متن کاملHuman sterol regulatory element-binding protein 1a contributes significantly to hepatic lipogenic gene expression.
BACKGROUND/AIMS Sterol regulatory element-binding protein (SREBP) 1, the master regulator of lipogenesis, was shown to be associated with non-alcoholic fatty liver disease, which is attributed to its major isoform SREBP1c. Based on studies in mice, the minor isoform SREBP1a is regarded as negligible for hepatic lipogenesis. This study aims to elucidate the expression and functional role of SREB...
متن کاملER alpha-AHR-ARNT protein-protein interactions mediate estradiol-dependent transrepression of dioxin-inducible gene transcription.
The aryl hydrocarbon receptor (AHR) and the aryl hydrocarbon receptor nuclear translocator (ARNT) form a heterodimeric transcription factor upon binding a wide variety of environmental pollutants, including 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). AHR target gene activation can be repressed by estrogen and estrogen-like compounds. In this study, we demonstrate that a significant component of...
متن کاملStudy of MYB Transcription Factor Gene Expression in Some Bread Wheat Cultivars of Sistan Region, Iran
Drought, an abiotic stress, considered as one of the factors limiting food resources. The plant responses to adaptive to such a condition are accompanied with changes in the expression pattern of some functional as well as regulatory genes. The MYB proteins include a big family of transcription factors which are highly important in regulating development process and immunizing responses of plan...
متن کاملMyb binding sites mediate negative regulation of c-myb expression in T-cell lines.
In hematopoietic cell development, the c-myb transcription factor plays an important role. c-myb mRNA is expressed at high levels in immature proliferating cells and in leukemic cells. We have investigated the regulatory role of Myb protein binding to the human c-myb promoter. Three Myb binding sites have been described at approximately 600 bp upstream of the cap site. By transient transfection...
