  Introduction Epidermal growth factor receptor (EGFR)-activating-mutant non-small cell lung cancer (NSCLC) often initially responds well to EGFR tyrosine kinase inhibitors (TKIs) (Haber et al., 2011); however, the disease almost always recurs about 10–13 months of therapy. Analysis of clinical spe

  Recently, a non-proteolytic role of COP1 in stabilizing PIF3 proteins in the dark has been revealed . Previous studies have shown that the endogenous levels of PIF3 protein in etiolated seedlings were nearly undetectable . Ling found that the GSK3-like kinase BRASSINOSTEROID-INSENSITIVE 2 (BIN2) p

  2021-08-19

  

  HCV has evolved mechanisms to evade humoral immune responses including high functional flexibility and variability of immunogenic portions of its envelope proteins. The highest sequence variability occurs in the first 27 BB-94 of the N-terminus of E2, which is referred to as the hypervariable regio

  A number of factors have been shown to remove blocking end groups in order to make the termini of DSBs ligatable. A common non-ligatable end is one that contains either a 3′ phosphate or 5′ hydroxyl. The polynucleotide kinase/phosphatase (PNKP) is the NHEJ processing enzyme responsible for removing

  In Arabidopsis the quartet1 (qrt1) mutant enables the same type of analysis of gametophytes (pollen) in sets of four (tetrads) derived from individual meioses 61., 62.. Pollen tetrads from one accession (Columbia-0) are used to pollinate a second polymorphic accessions (Landsberg erecta) resulting i

  Preparation of the regioisomeric pyridooxazepinones 10 and 11 was accomplished utilizing the synthetic sequence depicted in Scheme 3. Amide coupling of 63 and BMH-21 chloride 64 afforded amide 65. Removal of the alcohol protecting group, followed by base catalyzed cyclization afforded a 1:2.4 mixtu

  There have been two reports of tumor shrinkage in response to dasatinib treatment in lung SCC patients harboring the DDR2 kinase domain S768R mutation., In the first case described by Hammerman et al. a combination of erlotinib (an epithelial growth factor receptor inhibitor) and dasatinib was admin

  In a study on the time course of a mechanism-based inactivation of CYP3A by HIV protease inhibitors, Katzenmaier et al. [37] reported that the suppression of CYP3A activity continued for threedays after the discontinuation of ritonavir. In the present study, the CYP3A activity on day 28 after a seve

  CXCR1/2 The CXC receptor 1 and 2 (CXCR1 and CXCR2) have been well characterised in vertebrates. In mammals and birds, the two receptors are shared by the ELR+ CXC ligands, namely the CXCL8 family members that have proinflammatory roles in recruitment of neutrophils, monocytes and macrophages to s

  In a recent study, a CMV DNA load cut-off of 500 IU/ml in BAL fluid was found to have a positive predictive value of ∼50% for the presence of probable CMV pneumonia (considering a prevalence of this event of 10% among patients at risk and undergoing BAL testing). Tan et al., in contrast, found CMV D

  In conclusion, this study provides the first investigation of role of ACC receptors in parasitic nematodes. While research using C. elegans to evaluate anthelmintic targets is an excellent tool to provide relevant information, research on similar targets in parasitic nematode can provide key informa

  Activatable MRI probes MRI is commonly used in clinics around the world and has the advantages of outstanding tissue-penetration depth and extremely high spatial resolution for in vivo imaging [33]. MRI has relatively poor sensitivity and usually requires gnrh agonists agents to enhance the imag

  The E1 enzyme is the apex for downstream enzymatic cascades and signaling pathways mediated by Ub and Ub-like proteins (Ubls) (Pickart, 2001). Studying characteristics of E1 and its catalytic functions may throw light to the role of ubiquitination in cell development. All known eukaryotic E1 are mon

  The pseudo DUBs KIAA0157 and Abraxas are required for the catalytic function of BRCC36. Comparison of the BRCC36–KIAA0157 heterodimer structure with an inactive BRCC36 homodimer structure provides a model for understanding how this functional interplay is achieved.
