Background The up-regulation of CCAAT/enhancer binding protein delta (CEBPD) has frequently been observed in macrophages in age-associated disorders, including rheumatoid arthritis (RA). However, the role of macrophage CEBPD in the pathogenesis of RA is unclear. Methodology and Principal Findings We found that the collagen-induced arthritis (CIA) score and the number of affected paws in Cebpd−/− mice were significantly decreased compared with the wild-type (WT) mice. The histological analysis revealed an attenuated CIA in Cebpd−/− mice, as shown by reduced pannus formation and greater integrity of joint architecture in affected paws of Cebpd−/− mice compared with WT mice. In addition, immunohistochemistry analysis revealed decreased pannus proliferation and angiogenesis in Cebpd−/− mice compared with WT mice. CEBPD activated in macrophages played a functional role in promoting the tube formation of endothelial cells and the migration and proliferation of synoviocytes. In vivo DNA

Stress responses are critical for estrogen (E2) to induce apoptosis in E2-deprived breast cancer cells. Nuclear factor-kappa B (NF-κB) is well known as a therapeutic target to prevent stress responses in chronic inflammatory diseases including cancer. However, whether E2 activates NF-κB to participate in stress-associated apoptosis in E2-deprived breast cancer cells is unclear. We demonstrated that E2 differentially modulates NF-κB activity in E2-deprived breast cancer cells according to the treatment time. Because E2 initially has significant potential to down modulate the NF-κB activation, it completely suppresses the tumor necrosis factor alpha (TNFα)-induced NF-κB activation. We found that E2 preferentially and constantly enhances the expression of transcription factor CCAAT/enhancer binding protein beta (C/EBPβ) which is responsible for suppression of NF-κB activation by E2 in MCF-7:5C cells. The mTOR signaling pathway promotes repression of NF-κB by C/EBPβ which is confirmed by ...
In this work, we have shown that the transcription factor C/EBPβ directly regulates the expression of the C3 gene, and that this control could be relevant for the pro-inflammatory effects of this transcription factor. By microarray analysis and RT-PCR we showed that the hippocampal content of C3 transcripts was depleted in C/EBPβ −/− mice. The analysis of the C3 promoter showed that this gene was directly induced by C/EBPβ through a C/EBPβ consensus site located at −616/-599 position from the transcription start site. In accordance with these data, LPS induced the expression of C3 in glial cells, at least in part, through the induction of C/EBPβ since the repression of LPS-induction of C/EBPβ by shRNA interference blocked C3 increase. On the contrary, C/EBPβ overexpression by transient transfection induced C3 expression. Additionally, treatment of these cultures with LPS induced the levels of the pro-inflammatory factors IL-1β and COX-2, which were significantly reduced in those ...
CEBPD (C/EBP delta) is a member of the CCAAT-enhancer binding protein (C/EBP) family of transcription factors characterized by a b-Zip domain that mediates dimerization and DNA binding. CEBPD is induced in response to acute stressors such as cytokine stimulation, bacterial lipopolysaccharide (LPS), corticosteroids, radiation and hypoxia. We have previously reported that CEBPD has dual functions in breast cancer by both attenuating or enhancing oncogenic pathways depending on context (Balamurugan and Sterneck, 2013, Mendoza-Villanueva et al., 2016). Recent studies reveal that elevated Endoplasmic Reticulum (ER) stress is associated with the pathology of several diseases including cancer. Limiting supply of nutrients and oxygen in growing tumor cells disrupts the protein folding homeostasis resulting in activation of the unfolded protein response (UPR). The UPR includes pathways that support adaptation to stress, and that are also implicated in promoting malignant features and therapy resistance ...
December 29, 2004 - The Notch pathway is an important molecular signaling mechanism whose existence has been known, or at least hinted at, for nearly a century since the identification of a mutant strain of Drosophila fruit flies with "notched" wings in Thomas Hunt Morgans lab in 1910. Later studies revealed that the Notch gene encodes a receptor protein that extends through both sides of the cell membrane and which is capable of interacting with a ligand partner, such as the protein Delta, presented on the surface of a neighboring cell. This "juxtracrine" interaction causes the cleavage of an intracellular region of the Notch protein, loosing it into the cytoplasm and triggering the activation of transcription factors within the cells nucleus. In addition to its effects on wing structure in flies, Notch signaling is known to be important in a number of neural cell fate determination and developmental processes, and is conserved in species from human to roundworm. In all processes in which it ...

TNF-a was originally identified as a macrophage product implicated in the metabolic disturbances of chronic inflammation and malignancy. Later on, its biological actions were shown to further extend to anorexia, weight loss, and insulin resistance (7). Elevated adipose tissue expression of TNF-a mRNA has been reported in different rodent models of obesity as well as in clinical studies involving obese patients (23). TNF-a mRNA expression is positively correlated with body adiposity as well as with hyperinsulinemia, showing positive associations with fasting insulin and triglyceride concentrations. TNF-a inhibits the expression of the transcription factor CCAAT/ enhancer binding protein-a (CEBPa) and the nuclear receptor peroxisome proliferator-activated receptor (PPAR)y2 (8,12,14). Furthermore, TNF-a stimulates the nuclear factor- kB transcription factor (NFkB), which orchestrates a series of inflammatory events, including expression of adhesion molecules on the surface of both endothelial cells ...
ABSTRACT: Fluorescence lifetime imaging microscopy (FLIM) is now routinely used for dynamic measurements of signaling events inside living cells, including detection of protein-protein interactions. An understanding of the basic physics of fluorescence lifetime measurements is required to use this technique. In this protocol, we describe both the time-correlated single photon counting and the frequency-domain methods for FLIM data acquisition and analysis. We describe calibration of both FLIM systems, and demonstrate how they are used to measure the quenched donor fluorescence lifetime that results from F?rster resonance energy transfer. We then show how the FLIM-FRET methods are used to detect the dimerization of the transcription factor CCAAT enhancer binding protein-a in live mouse pituitary cell nuclei. Notably, the factors required for accurate determination and reproducibility of lifetime measurements are described. With either method, the entire protocol including specimen preparation, ...

Neutrophil-specific granule deficiency (SGD) is a rare disorder characterized by recurrent pyogenic infections, defective neutrophil chemotaxis and bactericidal activity, and lack of neutrophil secondary granule proteins. It has been linked to a defect in the transcription factor CCAAT/enhancer binding protein (CEBP) epsilon. Recently, loss-of-function mutations in SMARCD2 were identified from SGD patients. SMARCD2 is chromatin-remodeling factor, that interacts with CEBP epsilon ...

The CCAAT/enhancer-binding protein β (C/EBPβ) is a transcription factor, which was first identified as a regulator of differentiation and inflammatory processes mainly in adipose tissue and liver; however, its function in the brain was largely unknown for many years. Previous studies from our laboratory indicated that C/EBPβ is implicated in inflammatory process and brain injury, since mice lacking this gene were less susceptible to kainic acid-induced injury. We first performed cDNA microarrays analysis using hippocampal RNA isolated from C/EBPβ +/+ and C/EBPβ −/− mice. Immunocytochemical and immunohistochemical studies were done to evaluate C/EBPβ and C3 levels. Transient transfection experiments were made to analyze transcriptional regulation of C3 by C/EBPβ. To knockdown C/EBPβ and C3 expression, mouse astrocytes were infected with lentiviral particles expressing an shRNA specific for C/EBPβ or an siRNA specific for C3. Among the genes displaying

Having analysed data with TRANSFAC system, we may assume that the disturbed attachment of such factors as (C/EBP(CCAAT enhancer binding protein) Hoxa-3,Sp1 (serine protease inhibitor) or GATA-1, (GATA nucleotide sequence) may have an impact on IGF-1 protein synthesis, but we did not observed any significant correlation between promoter P1 polymorphism and serum IGF-1 levels ...
CCAAT/enhancer binding protein (C/EBP), epsilon, also known as CEBPE and CRP1, is a type of ccaat-enhancer-binding protein. CEBPE is its human gene and is pro-apoptotic. The protein encoded by this gene is a bZIP transcription factor which can bind as a homodimer to certain DNA regulatory regions. It can also form heterodimers with the related protein CEBP-δ. The encoded protein may be essential for terminal differentiation and functional maturation of committed granulocyte progenitor cells. Mutations in this gene have been associated with specific granule deficiency, a rare congenital disorder. Multiple variants of this gene have been described, but the full-length nature of only one has been determined.

N2 - Toll-like receptors (TLRs) are expressed on innate immune cells and trigger inflammation upon detection of pathogens and host tissue injury. TLR-mediated proinflammatory-signaling pathways are counteracted by partially characterized anti-inflammatory mechanisms that prevent exaggerated inflammation and host tissue damage as manifested in inflammatory diseases. We biochemically identified a component of TLR-signaling pathways, A20-binding inhibitor of NF-κB (ABIN1), which recently has been linked by genome-wide association studies to the inflammatory diseases systemic lupus erythematosus and psoriasis.

A recent paper in Nature Medicine showed that Down syndrome brains have reduced expression of Sorting nexin 27 (SNX27) and CCAAT/enhancer binding protein beta (C/EBP beta) and identified C/EBP beta as a transcription factor for SNX27. Down syndrome results in overexpression of miR-155, a chromosome 21-encoded microRNA that negatively regulates C/EBP beta, thereby reducing SNX27 expression. SNX27 is a brain-enriched […]. ...
