Project description:The Moutan Cortex Radicis (MCR) has been used as an analgesic, sedative and anti-inflammatory agent. This study investigated the changes in gene expression by MCR treatment when stimulated with lipopolysaccharide (LPS) in cultured human gingival fibroblasts (HGFs) and the gene expression changes by the MCR when challenged with LPS using a microarray chip.

Project description:Background. Pneumococcus is a major human pathogen and the polysaccharide capsule is considered its main virulence factor. Nevertheless, strains lacking a capsule, named non-typeable pneumococcus (NT), are maintained in nature and frequently colonise the human nasopharynx. Interest in these strains, not targeted by any of the currently available pneumococcal vaccines, has been rising as they seem to play an important role in the evolution of the species. Currently, there is a paucity of data regarding this group of pneumococci. Also, questions have been raised on whether they are true pneumococci. We aimed to obtain insights in the genetic content of NT and the mechanisms leading to non-typeability and to genetic diversity. Methods. A collection of 52 NT isolates representative of the lineages circulating in Portugal between 1997 and 2007, as determined by pulsed-field gel electrophoresis and multilocus sequence typing, was analysed. The capsular region was sequenced and comparative genomic hybridisation (CGH) using a microarray covering the genome of 10 pneumococcal strains was carried out. The presence of mobile elements was investigated as source of intraclonal variation. Results. NT circulating in Portugal were found to have similar capsular regions, of cps type NCC2, i.e., having aliB-like ORF1 and aliB-like ORF2 genes. The core genome of NT was essentially similar to that of encapsulated strains. Also, competence genes and most virulence genes were present. The few virulence genes absent in all NT were the capsular genes, type-I and type-II pili, choline-binding protein A (cbpA/pspC), and pneumococcal surface protein A (pspA). Intraclonal variation could not be entirely explained by the presence of prophages and other mobile elements. Conclusions. NT circulating in Portugal are a homogeneous group belonging to cps type NCC2. Our observations support the theory that they are bona-fide pneumococcal isolates that do not express the capsule but are otherwise essentially similar to encapsulated pneumococci. Thus we propose that NT should be routinely identified and reported in surveillance studies.

Project description:The Moutan Cortex Radicis (MCR) has been used as an analgesic, sedative and anti-inflammatory agent. This study investigated the changes in gene expression by MCR treatment when stimulated with lipopolysaccharide (LPS) in cultured human gingival fibroblasts (HGFs) and the gene expression changes by the MCR when challenged with LPS using a microarray chip. Human gingival fibroblast were divided into three experimental groups; 1, C: Control, 2, LPS: LPS-treatment only, 3, MCR40: LPS- and MCR40-treatments. Total RNA was isolated from each experimental fibroblast (3 experimental group M-CM-^W 1 sample of each experimental group = total 3 samples).

Project description:The wide application of pig disease model has caused a surge of interest in the study of derivation of pig induced pluripotent cells (iPSCs). Here we performed genome-wide analysis of gene expression profiling by RNA-seq and small RNA-seq and DNA methylation profile by MeDIP-seq in pig iPSCs through comparison with somatic cells. We identified mRNA and microRNA transcripts that were specifically expressed in pig iPSCs. We then pursued comprehensive bioinformatics analyses, including functional annotation of the generated data within the context of biological pathways, to uncover novel biological functions associated with maintenance of pluripotency in pig. This result supports that pig iPS have transcript profiles linked to ribosome, chromatin remodeling, and genes involved in cell cycle that may be critical to maintain their pluripotency, plasticity, and stem cell function. Our analysis demonstrates the key role of RNA splicing in regulating the pluripotency phenotype of pig cells. Specifically, the data indicate distinctive expression patterns for SALL4 spliced variants in different pig cell types and highlight the necessity of defining the type of SALL4 when addressing the expression of this gene in pig cells. MeDIP-seq data revealed that the distribution patterns of methylation signals in pig iPS and somatic cells along the genome. We identify 25 novel porcine miRNA, including pluripotency-related miR-302/367cluster up-regulated in pig iPSCs. At last, we profile the dynamic gene expression signature of pluripotent genes in the preimplantation development embryo of pig. The resulting comprehensive data allowed us to compare various different subsets of pig pluripotent cell. This information provided by our analysis will ultimately advance the efforts at generating stable naive pluripotency in pig cells.

Project description:Porcine pleuropneumonia caused by Actinobacilluspleuropneumoniae (APP) is a swine respiratory disease with an important impact around the world either as a single infection or part of the porcine respiratory disease complex. The data of interaction between hosts and pathogens has becoming more crucial for exploration of the mechanism. However, up to now, comparatively little information is available on the systemic and dynamic changes that occur in pig serum in response to APP infection. This study used iTRAQ to identify differentially expressed proteins (DEPs) in pig serum in response to APP infection.

We then pursued comprehensive bioinformatics analyses, including functional annotation of the generated data within the context of biological pathways, to uncover novel biological functions associated with maintenance of pluripotency in pig. This result supports that pig iPS have transcript profiles linked to “ribosome”, “chromatin remodeling”, and genes involved in “cell cycle “that may be critical to maintain their pluripotency, plasticity, and stem cell function.
