  In this study we generated mice in which the native Bcl6 locus was engineered to produce a form of Bcl6 containing a mutant RD2 domain that disrupts its repressor function. We found that RD2 domain is essential for pre-GC B cell differentiation and clustering into nascent GC within follicles, in par

  2020-12-08

  

  Introduction DNA-dependent protein kinase (DNA-PK) is a multicomponent serine/threonine protein kinase and considered a member of the phosphatidylinositol (PI) 3-kinase related kinase (PIKK family). This enzyme plays a critical role in the repair of mammalian DNA double strand breaks (DSBs) throu

  2020-12-08

  

  In studies directed toward the development of sequence-specific major-groove binding small silibinin [11], we desired a non-intercalating molecular scaffold that could direct attached moieties into the major groove. As an initial step toward this goal, we wished to study the DNA binding mode and a

  2020-12-08

  

  DNMT1is the dominating enzyme responsible for maintenance of the DNA methylation pattern and the primary enzyme responsible for copying methylation patterns following DNA replication (Moore et al., 2013). DNMT1 maintains the mitotic inheritance of the original methylation pattern in a cell lineage d

  2020-12-08

  

  The positive correlation between ATG7 and DCTPP1 (TCGA data) suggested our hypothesis that DCTPP1 may affect the phenotype of prostate tumor, or maybe other types of tumors as well, through its role in autophagy. To test this hypothesis, we carried out western-blot experiments in which the ratios of

  2020-12-08

  

  Previous studies from our laboratory have demonstrated that CysLT1R mRNA and protein expression can be upregulated by T2-type cytokines (IL-13, IL-4, and IL-5) in monocytes, macrophages, and eosinophilic HL-60 cells., To our knowledge, however, there are no studies on interactions of cytokines (suc

  Cells expressing the CDK5 S47D mutant exhibit impaired migration and enhanced proliferation: Finally, we wished to determine the functional significance of this phosphoevent. Multiple studies have implicated active CDK5 in promotion of cell migration [9,16,[21], [22], [23], [24]] and in one study th

  2020-12-08

  

  In contrast, exposure of CRF2(a) receptors to h/rCRF in living cells produced a strikingly weak translocation of βarrestin2 to the membrane. Specifically, we found a markedly lower magnitude and slower rate of βarrestin2 recruitment to CRF2(a) receptors in response to h/rCRF concentrations as high a

  Higher versus lower order skills can also be understood in the context of the CPA exam. The CPA exam tests four broad topics (FAR, AUD, BEC, REG) using three different testing modes: multiple-choice, task-based simulations and written communications. Combined, the three testing modes place more emph

  The aim of this study was to use molecular methods to characterise C. difficile isolates circulating in the Czech Republic from 2013 to 2015. Material and methods Discussion During a three-year period (2013–2015) a total of 32 hospitals voluntarily participated in this project, but only 11 ho

  2020-12-08

  

  The acetylcholinesterasic activity of exposed animals, after treatment with diverse concentrations of uranium and following distinct recovery periods, remained unaltered for all species. This finding suggests that uranium, in spite of being a water-soluble metal, does not exert any effect on the sel

  Introduction Breast cancer is the most common cancer in women and one of the leading causes of death worldwide. Estrogen receptor alpha (ERα, “wild-type” estrogen receptor), encoded by the estrogen receptor1 (ESR1) gene, is expressed in approximately 70% of all breast cancers. Hormonal therapy ha

  Another enzyme class that has emerged as a potential alternative to P450s are the so-called ‘unspecific peroxygenases’ (UPOs). They also contain a heme but are extracellularly expressed fungal enzymes that are often more stable than P450 monooxygenases. Importantly, UPOs use H2O2 instead of O2 as th

  2020-12-07

  

  Why are Tfh cell dynamics so fundamentally different in naive and immune animals? Initially, GC dopamine antagonist drugs must pass stringent affinity and specificity checkpoints to ensure only high-affinity non-self-reactive cells are selected. Therefore, restricting primary Tfh cells with the gre

  Given the link between E3s, autoimmunity, and antitumor immunity, it dapagliflozin is reasonable to assume that, similar to other ICBs, IRAEs may limit the clinical use of E3-targeting therapies – further stressing the need to better understand the underlying mechanisms of these unwanted effects.
