doi: bioRxiv preprint molecular biology. Our high-resolution data have enabled a precise study of transcription and translation in both pathogenic and attenuated forms of IBV, and expand our understanding of gammacoronaviral gene expression. We demonstrate that gene expression shows considerable intraspecies variation, with single nucleotide polymorphisms associated with altered production of sgmRNA transcripts, and our RiboSeq data sets enabled us to uncover novel ribosomally occupied ORFs in both strains. We also identify numerous cellular genes and gene networks that are differentially expressed during virus infection, giving insights into the host cell reponse to IBV infection. 3 47 48 49 50 51 52 53 54 55 56 author/funder.

Comparative analysis of gene expression in virulent and attenuated strains of infectious bronchitis virus at sub-codon resolution


question:
Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. Current therapies confer partial benefits either by incompletely improving airflow limitation or by reducing acute exacerbations, hence new therapies are desirable. In the absence of robust early predictors of clinical efficacy, the potential success of novel therapeutic agents in COPD will not entirely be known until the drugs enter relatively large and costly clinical trials. New predictive models in humans, and new study designs are being sought to allow for confirmation of pharmacodynamic and potentially clinically meaningful effects in early development. This review focuses on human challenge models with lipopolysaccharide endotoxin, ozone, and rhinovirus, in the early clinical development phases of novel therapeutic agents for the treatment and reduction of exacerbations in COPD.
answer:
Challenge models to assess new therapies in chronic obstructive pulmonary disease


question:
So far, there has been scarce information about the status of immunoglobulins (Ig) and the gene expression of inflammatory cytokines in buffaloes showing digestive troubles. The purpose of the present study was to explore the modulation of gene expression of some immuneinflammatory markers in buffaloes suffered from various digestive disorders. For this reason, 50 native breed water buffaloes were studied. Forty of these buffaloes showed various symptoms of digestive disorders and were allocated into 4 groups of equal sizes (group 1: uncategorized stomatitis; group 2: acute traumatic reticuloperitonitis [TRR]; group 3: acute rumen impaction; and group 4: undifferentiated enteritis). Ten apparently healthy buffaloes were randomly selected and considered as a control group. RNA was firstly extracted from the whole blood then a reverse transcription kits was used to convert the RNA to cDNA. Real-time PCR was used to measure the expression of mRNAs of interleukin (IL)-1β, IL-6, IL-10, and tumor necrosis factor (TNF)-α, IgG, and IgA, while glyceraldehyde-3-phosphate dehydrogenase (GAPDH) used as an internal reference. The results of realtime PCR revealed a significant (P ≤ 0.05) upregulation of the gene expression of IL-1β, IL-6, IL-10, and TNF-α in blood of diseased buffaloes compared with those of controls. Animals showing acute TRP had peak values of both IL-6 and IL-10; while those exhibiting enteritis and rumen impaction had the highest values of IL-1β and TNF-α, respectively. The results of qPCR also revealed a significant (P ≤ 0.05) downregulation of both IgG and IgA gene expression in blood of all diseased buffaloes compared with controls. The lowest values of both genes were recorded in buffaloes showing acute TRP. The results herein suggest that the tested genes could have a pivotal role in the pathophysiologic mechanism of the underlying diseases.
answer:

Modulation of immunity and inflammatory gene expression in buffalo (Bubalus bubalis) with some digestive disorders
