The porcine microRNA transcriptome response to porcine cytomegalovirus infection

Project description:Porcine cytomegalovirus (PCMV; genus Cytomegalovirus, subfamily Betaherpesvirinae, family Herpesviridae) is an immunosuppressive virus that mainly inhibits the immune function of T lymphocytes and macrophages, which has caused great distress to the farming industry. In this study, we obtained the miRNA expression profiles of PCMV-infected and control porcine macrophages, PCMV-infected and control porcine tissues via high-throughput sequencing. The comprehensive analysis of miRNA profiles showed that 306 miRNA database annotated and 295 novel pig-encoded miRNAs were detected. Gene Ontology (GO) analysis of the target genes of miRNAs in PCMV infected porcine macrophages showed that the differentially expressed miRNAs are mainly involved in immune and metabolic process. This is the first report of the miRNA transcriptome in PCMV infected porcine macrophages and PCMV infected tissues and the analysis of the miRNA regulatory mechanism during PCMV infection. Further research into the regulatory mechanisms of miRNAs during immunosuppressive viral infections will contribute to the treatment and prevention of immunosuppressive viruses. miRNA expression profiling of PCMV-infected and control porcine macrophages; PCMV-infected and control porcine tissues via high-throughput sequencing.

Transcriptome Profiling of Ten Porcine Tissues at the Gene, Isoform and TSS level

Project description:In this study we have employed RNA seq on ten different tissues including four brain tissues from two boars to gain a understanding of the differential variations in transcriptional profiles for these tissues consisting of occipital cortex, frontal cortex, hypothalamus and cerebellum along with such diverse tissues as heart, spleen, liver, kidney, lung and musculus longissimus dorsi. This has enabled us to perform comparative gene expression analysis of brain regions versus non-brain tissues along with inter-brain tissue comparisons. Hence, we have tested for differentially expressed genes and isoforms, differential splicing, transcription start sites (TSS), and differential promoter usage between all ten porcine tissues.

On the characterisation of the porcine gland-specific salivary proteome using MALDI-TOF/TOF MS and Q-Exactive orbitrap MS/MS

Project description:To expand the knowledge on the porcine salivary proteome, secretions from the three major salivary glands were collected from anaesthetised piglets. Pilocarpine and isoproterenol were simultaneously injected intraperitoneally to increase the volume and protein concentration of the saliva, respectively. The protein composition and relative protein-specific abundance of saliva secreted by the parotid gland and by the mandibular and monostomatic sublingual gland, were determined using iTRAQ. When combining two detection methods, MALDI-TOF/TOF MS and Q-Exactive orbitrap MS/MS, a total of 122 porcine salivary proteins and 6 mammalian proteins with a predicted porcine homolog were identified. Only a quantitative and not a qualitative difference was observed between both ductal secretions. The 128 proteins were detected in both secretions, however, at different levels. Twenty-four proteins (20 porcine, 4 mammalian with a predicted porcine homolog) were predominantly secreted by the parotid gland, such as carbonic anhydrase VI and alpha-amylase. Twenty-nine proteins (all porcine) were predominantly secreted by the mandibular and sublingual glands, for example salivary lipocalin and submaxillary apomucin protein.

Acid bone lysates: what we eliminate by preparing demineralized bone matrix

Project description:Demineralized bone matrix is a widely used allograft where not only the inorganic mineral but also embedded growth factors are removed by hydrochloric acid. The cellular response to the growth factors released during the preparation of demineralized bone matrix, however, has not been studied. Here we investigated the in vitro impact of acid bone lysates (ABL) prepared from porcine cortical bone chips on oral fibroblasts. Proteomic analysis of ABL revealed a large spectrum of bone-derived proteins including TGF-β1. Whole genome microarrays and RT-PCR together with the pharmacologic blocking of TGF-β receptor type I kinase with SB431542 showed that ABL activates the TGF-β target genes interleukin 11, proteoglycan 4, and NADPH oxidase 4. Interleukin 11 expression was confirmed at the protein level by ELISA. Immunofluorescence and Western blot showed the nuclear localization of Smad2/3 and increased phosphorylation of Smad3 with ABL, respectively. This effect was independent of whether ABL was prepared from mandible, calvaria or tibia. ABL prepared with 0.1 N HCL was most effective compared to lysates obtained with 0.01 N and also 1.0 N HCl. These results demonstrate that TGF-β is a major growth factor that is removed upon the preparation of demineralized bone matrix.

The porcine microRNA transcriptome response to transmissible gastroenteritis virus infection

Project description:Transmissible gastroenteritis virus (TGEV; Coronaviridae family) causes huge economic losses to the swine industry. MicroRNAs (miRNAs) play a regulatory role in viral infection and may be involved in the mammalian immune response. Here, we report a comprehensive analysis of host miRNA expression in TGEV-infected swine testis (ST) cells. Deep sequencing generated 3,704,353 and 2,763,665 reads from uninfected ST cells and infected ST cells, respectively. The reads were aligned to known Sus scrofa pre-miRNAs in miRBase 19, identifying 284 annotated miRNAs. Certain miRNAs were differentially regulated during TGEV infection, which confirmed the hypothesis that specific miRNAs play a regulatory role in virus-host interactions. 59 unique miRNAs displayed significant differentially expression between the normal and TGEV-infected ST cell samples: 15 miRNAs were significantly up-regulated and 44 were significantly down-regulated. Stem-loop RT-PCR was carried out to determine the expression levels of specific miRNAs in the two samples, and the results were consistent with those of sequencing. Gene ontology enrichment analysis of host target genes demonstrated that the differentially expressed miRNAs are involved in regulatory networks, including cellular process, metabolic process, immune system process. This is the first report of the identification of ST cell miRNAs and the comprehensive analysis of the miRNA regulatory mechanism during TGEV infection, which revealed the miRNA molecular regulatory mechanisms for the viral infection, expression of viral genes and the expression of immune-related genes. The results presented here will aid research on the prevention and treatment of viral diseases. 2 ST(Porcine testicular cells) cell samples, ST: normal ST cell sample (contro sample), TGEV: TGEV (Transmissible gastroenteritis virus) infected ST cell samples

Reprogramming of transcriptome after hormetic heat stress by the endoribonuclease ENDU 2 improves lifespan and stress resistance in C. elegans

Project description:Organisms' ability to respond to life-threatening environmental impacts is crucial for their survival. While acute stress responses to unfavorable factors are well known, the physiological consequences of transient stress experiences over time, as well as their underlying mechanisms, are not well understood. In this study, we investigated the long-term effects of a short heat shock (HS) exposure on the transcriptome of C. elegans. We found that the canonical HS response was followed by a profound transcriptional reprogramming affecting many genes involved in innate immunity response. This reprogramming relies on the endoribonuclease ENDU-2 but not the heat shock factor 1 (HSF-1). ENDU-2 in this context co-localizes with chromatin and interacts with RNA polymerase Pol II, enabling specific regulation of transcription in the post-HS period. Failure to activate this post-HS response does not impair animal survival under continuous HS insult but eliminates the beneficial effects of hormetic HS. In summary, our work discovers that the RNA-binding protein ENDU-2 mediates the hormetic long-term effects of transient HS to determine aging and longevity.

TGFβ activity released from platelet-rich fibrin adsorbs to titanium surface and collagen membranes

Project description:Considering that PRF is clinically used in combination with dental implants and collagen membranes, we exposed titanium discs and collagen membranes to PRF lysates. We showed here that PRF-derived TGF-β activity adsorbs to titanium implants and collagen membranes indicated by the changes in gene expression and immunoassay analysis. Our study points towards TGF-β as major target of PRF and suggest that TGF-β activity released by PRF adsorbs to titanium surface and collagen membranes.
