BACKGROUND The microbiota of the bovine upper respiratory tract has been recently characterized, but no data for the lower respiratory tract are available. A major health problem in bovine medicine is infectious bronchopneumonia, the most common respiratory syndrome affecting cattle. With this study, we used 16S rRNA gene sequencing to characterize and compare the microbial community compositio...
The structural gene of the H-NS protein, a global regulator of bacterial metabolism, has been identified in the group of enterobacteria as well as in closely related bacteria, such as Erwinia chrysanthemi and Haemophilus influenzae. Isolated outside these groups, the BpH3 protein of Bordetella pertussis exhibits a low amino acid conservation with H-NS, particularly in the N-terminal domain. To ...
Noonan syndrome (NS), the most common single-gene cause of congenital heart disease, is an autosomal dominant disorder that also features proportionate short stature, facial abnormalities, and an increased risk of myeloproliferative disease. Germline-activating mutations in PTPN11, which encodes the protein tyrosine phosphatase SHP2, cause about half of NS cases; other causative alleles include...
زمینه و هدف: لوسمی پرومیلوسیتیکی حاد(apl) نوعی بیماری خونی بدخیم می باشد که در اثر تکثیر بی رویه و عدم تمایز سلول های بنیادی خون ساز ایجاد می شود. از راهکارهای اخیر در درمان لوسمی شناسایی مسیرهای سیگنالی درگیر در سلول های بنیادی سرطان خون می باشد. نوکلئوستمین (ns) نقش عمده ای در کنترل رشد و خودنوزایی سلول های بنیادی و سرطانی دارد. در اینجا، اثرات خاموشی ژن ns بر روی رشد، تمایز و مرگ رده سلولی n...
Nucleoid-associated proteins (NAPs) facilitate chromosome organization in bacteria, but the precise mechanism remains elusive. H-NS is a NAP that also plays a major role in silencing pathogen genes. We used genetics, single-particle tracking in live cells, superresolution microscopy, atomic force microscopy, and molecular dynamics simulations to examine H-NS/DNA interactions in single cells. We...
Nephrotic syndrome (NS) is a clinicopathological entity characterized by proteinuria, hypoalbuminemia, peripheral edema, and hyperlipidemia. It is the most common cause of glomerular disease in children and adults. Although the molecular pathogenesis of NS is not completely understood, data from the study of familial NS suggest that it is a "podocytopathy." Virtually all of the genes mutated in...
