TurboID screening of ApxI toxin interactants identifies host proteins involved in Actinobacillus pleuropneumoniae-induced apoptosis of immortalized porcine alveolar macrophages.

Actinobacillus pleuropneumoniae (APP) is a gram-negative pathogenic bacterium responsible for porcine contagious pleuropneumonia (PCP), which can cause porcine necrotizing and hemorrhagic pleuropneumonia. Actinobacillus pleuropneumoniae-RTX-toxin (Apx) is an APP virulence factor. APP secretes a total of four Apx toxins, among which, ApxI demonstrates strong hemolytic activity and cytotoxicity, causing lysis of porcine erythrocytes and apoptosis of porcine alveolar macrophages.

Porcine Epidemic Diarrhea Virus and Its nsp14 Suppress ER Stress Induced GRP78.

Porcine epidemic diarrhea virus (PEDV), a member of the α-coronavirus genus, can cause vomiting, diarrhea, and dehydration in piglets. Neonatal piglets infected with PEDV have a mortality rate as high as 100%. PEDV has caused substantial economic losses to the pork industry.

TurboID Screening of the OmpP2 Protein Reveals Host Proteins Involved in Recognition and Phagocytosis of by iPAM Cells.

Glaesserella parasuis is a common bacterium in the porcine upper respiratory tract that causes severe Glasser's disease, which is characterized by polyarthritis, meningitis, and fibrinous polyserositis. TurboID is an enzyme that mediates the biotinylation of endogenous proteins that can fuse with proteins of interest to label protein interactors and local proteomes. To reveal the host proteins that interact with outer membrane protein P2 (OmpP2) by TurboID-mediated proximity labeling in immortalized porcine alveolar macrophage iPAM cells, 0.

Transcriptome analysis of heat resistance regulated by quorum sensing system in .

The ability of bacteria to resist heat shock allows them to adapt to different environments. In addition, heat shock resistance is known for their virulence. Our previous study showed that the AI-2/luxS quorum sensing system affects the growth characteristics, biofilm formation, and virulence of .

Inhibition of Porcine Epidemic Diarrhea Virus by Cinchonine Inducing Cellular Autophagy.

Porcine epidemic diarrhea virus (PEDV) could cause lethal diarrhea and dehydration in suckling piglets, which can adversely affect the development of the global swine industry. The lack of effective therapeutical and prophylactic treatment especially for PEDV variant strains underlines the importance of effective antiviral strategies, such as identification of novel antiviral agents. In the present study, the antiviral activity of cinchonine against PEDV was investigated in Vero CCL81 and LLC-PK1 cells at a non-cytotoxic concentration determined by Cell Counting Kit-8 assay .

Levistolide A Inhibits PEDV Replication via Inducing ROS Generation.

Porcine epidemic diarrhea virus (PEDV) variant strains adversely affect the production of pigs globally. Vaccines derived from PEDV traditional strains impart less protection against the variant strains. Moreover, sequence diversity among different PEDV variant strains is also complicated.

Deletion of the crp gene affects the virulence and the activation of the NF-κB and MAPK signaling pathways in PK-15 and iPAM cells derived from G. parasuis serovar 5.

Glaesserella parasuis can cause serious systemic disease (Glasser's disease) that is characterized by fibrinous polyserositis, polyarthritis and meningitis. cAMP receptor protein (CRP) is among the well studied global regulator proteins which could modulate the virulence of many pathogenic bacteria. Our previous study showed that the crp gene was involved in the regulation of growth rate, biofilm formation, stress tolerance, serum resistance, and iron utilization in G.

The changes of microRNA expression profiles and tyrosinase related proteins in MITF knocked down melanocytes.

Microphthalmia-associated transcription factor (MITF) is a master regulator in melanocyte proliferation, development, survival and melanoma formation. In melanocyte dysfunction disease, it is observed that the expressions of MITF, tyrosinase (TYR), tyrosinase related protein 1 (TYRP1) and tyrosinase related protein 2 (TYRP2)/dopachrome tautomerase (DCT) are changed, the consequence of which remains unclear. In this study, we focused on the change of microRNA (miRNA) profiles and Tyrosinase Related Proteins (TRPs) in MITF knocked down melanocytes.

Evaluation of the exercise workload of broadcast calisthenics for children and adolescents aged 11-17 years.

The aim of this study was to examine the exercise workload of the 3rd Series of National Broadcast Calisthenics for Elementary and Middle School Students. Altogether, 120 students aged 11-17 years were randomly selected from elementary and middle schools to participate in the study. Each participant performed a cycle ergometer test to obtain maximum oxygen uptake ([Vdot]O(2max)) and maximum heart rate values.
