In multicellular organisms, Polycomb Repressive Complex 1 (PRC1) and PRC2 repress target genes through histone modification and chromatin compaction. Arabidopsis thaliana mutants strongly compromised in the pathway cannot develop differentiated organs. LIKE HETEROCHROMATIN PROTEIN1 (LHP1) is so far the only known plant PRC1 component that directly binds to H3K27me3, the histone modification set...
ABSCISIC ACID-RESPONSIVE ELEMENT BINDING PROTEIN1 (AREB1) (i.e., ABF2) is a basic domain/leucine zipper transcription factor that binds to the abscisic acid (ABA)-responsive element (ABRE) motif in the promoter region of ABA-inducible genes. Here, we show that expression of the intact AREB1 gene on its own is insufficient to lead to expression of downstream genes under normal growth conditions....
objective: creb1 is an important downstream protein for many signaling pathways. by designing efficient sirnas against creb1, it may be possible to assess the role of molecules involved in signaling pathways in different cell types. in this research the efficiency of creb1 knockdown by two different sirnas in k562 cells has been studied. materials and methods: sirnas have been designed accordi...
The RNA binding protein CPEB regulates dendrite morphogenesis and neuronal circuit assembly in vivo.
Visual system development requires experience-dependent mechanisms that regulate neuronal structure and function, including dendritic arbor growth, synapse formation, and stabilization. Although RNA binding proteins have been shown to affect some forms of synaptic plasticity in adult animals, their role in the development of neuronal structure and functional circuitry is not clear. Using two-ph...
The liver is a central organ that controls systemic energy homeostasis and nutrient metabolism. Dietary carbohydrates and lipids, and fatty acids derived from adipose tissue are delivered to the liver, and utilized for gluconeogenesis, lipogenesis, and ketogenesis, which are tightly regulated by hormonal and neural signals. Hepatic lipogenesis is activated primarily by insulin that is secreted ...
Introduction: Spermatogenesis is a strictly regulated process in sperm production that is needed for sperm production transcriptional and posttranscriptional regulations. The cytoplasmic polyadenylation element binding (CPEB) protein regulates cytoplasmic polyadenylation of mRNAs in oogenesis and spermatogenesis. The purpose of the present studywas examining the association between rs2303846, ...
Background UP elements (upstream element) are DNA sequences upstream of a promoter that interact with the α-subunit of RNA polymerase (RNAP) and can affect transcription by altering the binding RNAP to DNA. However, details of UP element and binding affinity effects on transcriptional strength are unclear. Results Here, we investigated the effects of UP element sequences on gene transcription...
The mechanism of action of retinoic acid (RA) is of broad relevance to cell and developmental biology, nutrition, and cancer chemotherapy. RA is known to induce expression of the Burkitt's lymphoma receptor 1 (BLR1) gene which propels RA-induced cell cycle arrest and differentiation of HL-60 human myeloblastic leukemia cells, motivating the present analysis of transcriptional regulation of blr1...
CCAAT displacement protein (CDP) is a transcriptional repressor that restricts expression of the gp91(phox) gene to mature myeloid cells. CDP interacts with multiple sites within the -450 to +12 bp human gp91(phox) promoter, and down-regulation of CDP DNA-binding activity is required for induction of gp91(phox) transcription in mature phagocytes. Truncation of the gp91(phox) promoter to -102 to...
