In the present study, a type of graphitic mesoporous carbon (denoted as GMC) is synthesized and its structural properties were characterized by nitrogen physisorption isotherms, transmission electron microscopy and Raman spectroscopy. According to BET and BJH methods, the specific surface area (SBET) and the average pore diameter of GMC are estimated to be 720 m2/g and 3.4 nm, respectively....

Adsorbent prepared from waste plants for the treatment of dyeing effluents have high significance in environmental sustainability. In this research, adsorption of Acid Blue 92AB 92 dye from aqueous solutions on raw and modified diatomite nickel oxide nanoparticles was studied. The effect of different operation parameters such as pH, contact time, initial dye concentration, calcinations and sorb...

Four experiments were conducted to determine whether betaine (BET) could replace dietary methionine (MET) in diets for weanling pigs. Pigs in each experiment were allotted to treatments on the basis of weight in a randomized complete block design. Each treatment was replicated four (Exp. 4), five (Exp. 1 and 2), or six (Exp. 3) times with five or six pigs per replicate. In Exp. 1, pigs were fed...

INTRODUCTION The BET family of bromodomain-containing proteins constitute epigenetic readers that bind to acetylated lysine residues of core histones, thereby translating epigenetic histone marks to effects on gene expression. BET inhibitors are currently emerging as promising therapeutic agents for treatment of various pathological conditions. Here, we explored the potential of using BET inhib...

BACKGROUND Systemic lupus erythematosus (SLE) is characterized by the aberrant activation of T-lymphocytes. Since T-bet is the principal transcription factor for the differentiation of type-1 helper T-lymphocyte, we study the impact of urinary T-bet mRNA expression in clinically quiescent SLE patients on the risk of subsequent disease flare. METHODS We studied 60 quiescent SLE patients. Urina...

NFκB (Nuclear Factor-κ-light-chain-enhancer of activated B cells) signaling elicits global transcriptional changes by activating cognate promoters and through genome-wide remodeling of cognate regulatory elements called "super enhancers". BET (Bromodomain and Extra-Terminal domain) protein family inhibitor studies have implicated BET protein member BRD4 and possibly other BET proteins in NFκB-d...

The transcription factors signal transducer and activator of transcription (STAT)1 and T-bet control the differentiation of interferon (IFN)-gamma-producing T helper type (Th)1 cells. Here we compare the role of T-bet and STAT1 in the initiation and regulation of experimental autoimmune encephalomyelitis (EAE), a disease initiated by Th1 cells. T-bet-deficient mice immunized with myelin oligode...

Foamy viruses (spumaretroviruses) represent a retroviral genus which exhibits unusual features relating it to pararetroviruses. Previously, we reported the existence of a protein species harboring Env, Bel, and Bet epitopes in human foamy virus (HFV)-infected cells (M. L. Giron, F. Rozain, M. C. Debons-Guillemin, M. Canivet, J. Périès, and R. Emanoil-Ravier, J. Virol. 67:3596-3600, 1993). Here,...

Despite a high similarity with homologous protein families, only few proteins trigger an allergic immune response with characteristic TH2 polarization. This puzzling observation is illustrated by the major birch pollen allergen Bet v 1a and its hypoallergenic protein isoforms, e.g., Bet v 1d. Given the key role of proteolytic processing in antigen presentation and T cell polarization, we invest...

Bromodomains have emerged as attractive candidates for the development of inhibitors targeting gene transcription. Inhibitors of the bromo and extraterminal (BET) family recently showed promising activity in diverse disease models. However, the pleiotropic nature of BET proteins regulating tissue-specific transcription has raised safety concerns and suggested that attempts should be made for do...
