...s. The highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) is a major concern for the swine industry and causes high degrees of morbidity and mortality. The intracellular signalling cascades of the innate immune system triggered by HP-PRRSV often lead to the elimination of infection. However, HP-PRRSV induces pathological changes and can cause aberrant immune responses in the host, resulting in acute lung injury and immune dysfunct...

...or PGA was injected into porcine oocytes at different concentrations. The results showed that the blastocyst rates in injection 560 ng/μL Npm and 1000 ng/μL PGA groups were higher than those of other groups. Moreover, the blastocyst rate was highest in injection 560 ng/μL Npm group and was lowest in injection 100 ng/μL PGA group. These data suggested that addition of recombinant Npm obtained by prokaryotic expression or PGA could improve the develo...

The highest level of transcripts was found in the camel testis, followed by liver, spleen, kidney and lung. CdGSTP1-1 was heterologously expressed in Eschericia coli BL21(DE3) as a ~24 kDa soluble protein and showed to be catalyticly active towards the model substrate 1-chloro-2,4-dinitrobenzene. The results of the p...

Thus, freshly isolated porcine hepatocytes were used as a somatic cell model to study the internalization and subcellular localization of porcine growth hormone (pGH), and the results showed that pGH could be internalized into porcine hepatocytes in a time-dependent manner. The results also showed ...

This study established a reverse transcription-loop-mediated isothermal amplification (RT-LAMP) assay to detect PRRSV. Four primers were designed targeting the ORF5 gene of PRRSV were designed. Reverse transcription and amplification of the viral RNA using AMV reverse transcriptase was optim...

The experiment consisted of 1 control treatment and 5 levels of CT treatments (1×10-12 to 1×10-8 mol/L), and each treatment has 6 replications. Cell proliferation was determined by the MTT method. Cell morphology and phosphorus concentration in the cell supernatant were measured after 24 h of CT treatment. The NaPi-IIb protein expression was determined by W...

Here, we cloned the complete coding sequence (CDS) of E2F3b and identified seven alternatively spliced transcripts in pigs using molecular biology technique for the first time. The CDS of the canonical transcripts (named V1) of porcine E2F3b is 1023 bp in length, and showed 93.35% and 90.62% identities with the homologues from human and mouse, respectively. The splicing variants were pr...

...n towards the intestinal porcine enterocyte cells (IPEC-J2) were reduced significantly, and the cytotoxicity decreased. The results of RT-PCR showed that in F18ab△hcp1, the flagella gene flic and type I fimbriae fimA were significantly down-regulated. In conclusion, hcp1 gene of F18 STEC is related to flagella expression, bacterial adherence, invasion, and secretion of Stx2e toxin. T6SS hcp1 is proved to be closely involved in the pathogenesis of F18 STEC.
