Increased expression of epithelial cell-derived neutrophil-activating peptide (ENA-78) has been reported in several immune and inflammatory conditions suggesting its role in inflammatory response. We have identified two single nucleotide polymorphisms in the promoter and exon 2 of the ENA-78 gene by scanning the full length gene using DHPLC DNA fragment analysis and DNA sequencing. The polymorp...
background: cholera toxin b subunit (ctb) has been extensively considered as an immunogenic and adjuvant protein, but its yield of expression is not satisfactory in many studies. the aim of this study was to compare the expression of native and mutant recombinant ctb (rctb) in pqe vector. methods: ctxb fragment from vibrio cholerae o1 atcc14035 containing the substitution of mutant ctxb for ami...
In this issue of Blood, Pidala et al add a missing piece of information on the impact of amino acid substitutions (AASs) at specific peptide positions of class I antigens.
The role of positive darwinian selection in evolution at the molecular level has been keenly debated for many years, with little resolution. However, a recent increase in DNA sequence data and the development of new methods of analysis have finally made this question tractable. Here, I review the current state-of-play of the field. Initial estimates in Drosophila suggest that approximately 50% ...
Background: Metformin is an insulin sensitizing drug, which is co-administered with Clominophene citrate or gonadotropins in most cases of polycystic ovary syndrome (PCOS), to improve ovulation. STK11 gene is necessary for action of metformin. Therefore the study of STK11 polymorphisms is important as pharmacogenetics aspects of metformin. The aim of our study was to investigate polymorphism of...
introduction the accumulation of improperly folded forms of host-encoded cellular prion protein (prpc) in the central nervous system (cns) lead to a fatal neurodegenerative disease in sheep and goats, namely scrapie. the application of genetic breeding programs to eradicate transmissible spongiform encephalopathies in goats is an important aim for reasons of animal welfare as well as human food...
We characterized the complete genome of a putative novel Usutu virus (USUV) strain (Usutu-BONN) detected in a dead blackbird from Germany. Genomic analysis revealed several unique amino acid substitutions among the polyprotein gene. Phylogenetic analyses demonstrated that Usutu-BONN constitutes a putative novel African USUV lineage, which was probably recently introduced to central Europe.
