Project description:Laboratory tests with marine flatfish were conducted to investigate associations among gene expression, higher biological responses and wastewater effluent exposure. Previous studies showed molecular responses such as elevated concentrations of plasma estradiol and vitellogenin in wild male hornyhead turbot (Pleuronichthys verticalis). In the present study, male hornyhead turbot were exposed to environmentally realistic (0.5%) and higher (5%) concentrations of chemically enhanced advanced-primary (PL) and full-secondary treated (HTP) effluents from two southern California wastewater treatment plants (WWTP). Hepatic gene expression was examined using a custom low-density microarray. <br><br>
Project description:We established a bacteria infective intestinal inflammation in turbot (Scophthalmus maximus). And found that β-glucan could significantly alleviate the phenotype of turbot intestinal inflammation. We performed single cell transcriptome analysis to study bacteria infective intestinal inflammation and the effects of β-glucan. Furthermore, we revealed that β-glucan through activates Th17 cells to alleviate intestinal inflammation in turbot.
Project description:Cell types of turbot blood leukocytes remian unknown. We used single cell RNA sequencing (scRNA-seq) to analyze the cell types of turbot blood leukocytes.
Project description:To investigate the impact of pathogenic immune stimulation on the lipid droplet (LD) proteome of turbot (Scophthalmus maximus), turbot were intraperitoneally injected with PBS (XA01292LQ_P), wild-type Edwardsiella piscicida EIB202 (XA01292LQ_W), or inactivated E. piscicida EIB202 (XA01292LQ_T). Liver tissues were collected, and LDs were extracted for 4D label-free quantitative proteomics analysis.
Project description:Our present study analyzes decidual natural killer(dNK) cells expression profiles of the lncRNA and mRNA in missed abortional patients. A total of 276 mRNAs and 67 lncRNAs were identified to be significantly dysregulated in missed abortion (p<0.01). Subsequently, the potential function of dysregulated mRNAs and lncRNAs in missed abortion were explored through the bioinformatics method. In addition, the relationship between these dysregulated lncRNAs and mRNAs was revealed through constructing the lncRNA-mRNA interaction network. Our data showed that upregulated mRNAs were enriched in immune response and cytokine-cytokine receptor interaction while downregulated mRNAs were mainly related to cell adhesion and ECM-receptor interaction. Most importantly, several novel lncRNAs in dNKs, regulating core maternal-fetal interface activation-related mRNAs, were algorithmically predicted, indicating involvement of lncRNAs in the pathogenesis in early missed abortion.Topology analysis of lncRNA-mRNA interaction network suggested that the network presented a small world property, which means that most of mRNAs in the network were regulated by relative small number of hub lncRNAs. This study paves the way of investigating pathogenesis of early human missed abortion and facilitating the development of novel missed abortion therapeutics targeting lncRNAs.
Project description:ChIP sequencing of chordoma UCH-1 cell line. A well characterised chordoma cell line which bears all the morphological and immunohistochemical features of a chordoma (large vacuolated slow-growing cells, brachyury and cytokeratin-positive) have been used in this study. Chromatin immunoprecipitation using a well characterised anti-Brachyury antibody which has been used in immunohistochemistry of chordoma samples and previous ChIP studies in other systems. This data is part of a pre-publication release.

Project description:With the aim of shedding light on the protection conferred by the DNA vaccines based in the G glycoprotein of viral haemorrhagic septicaemia virus (VHSV) in turbot (Scophthalmus maximus) we have used a specific microarray highly enriched in antiviral sequences to carry out the transcriptomic study associated to VHSV DNA vaccination/infection. The differential gene expression pattern in response to empty plasmid (pMCV1.4) and DNA vaccine (pMCV1.4-G860) intramuscular administration with regard to non-stimulated turbot was analyzed in head kidney at 8, 24 and 72 hours post-vaccination. Moreover, the effect of VHSV infection one month after immunization was also analyzed in vaccinated and non-vaccinated fish at the same time points. A total number of 204 juvenile turbot were divided into 3 groups, two of them containing 72 fish and the last one 60 fish. Turbot were anaesthetized by immersion in 50 mg/ml buffered tricaine methanesulfonate (MS-222; Sigma) and then, fish from the first two groups were intramuscularly (i.m.) injected with 50 µl of PBS containing 2 µg of pMCV1.4 or pMCV1.4-G860. Turbot from the last batch were i.m. inoculated with 50 µl of PBS. At 8, 24 and 72 h after injection, 12 fish were removed from the first two tanks and, at 8 h after PBS inoculation, other 12 fish were taken from the last tank. These turbot were sacrificed by anaesthetic overdose and the head kidney was removed. Equal amounts of tissue from three fish belonging to the same tank and sampling point were pooled, obtaining 4 biological replicates for each treatment and time point (3 turbot/replicate). The remaining fish (36 in the plasmid-injected groups and 48 in the PBS-inoculated tank) were maintained during one month and then, 12 fish from the PBS injected group were separated to another tank. This new group of fish was intraperitoneally (i.p.) injected with 50 µl of MEM + penicillin and streptomycin + 2% FBS (PBS - MEM group), whereas the other turbot were i.p. infected with a dose of VHSV860 of 5 x 105 TCID50/fish (pMCV1.4 - VHSV and pMCV1.4-G860 - VHSV groups). At 8, 24 and 72 hours after infection, 12 fish were removed from the VHSV-infected tanks, and at 8 h after MEM injection the 12 fish were taken from the non-infected tank. The fish were sacrificed by anaesthetic overdose and the head kidney was removed. Equal amounts of tissue from three fish belonging to the same tank and sampling point were pooled, obtaining 4 biological replicates for treatment and time point (3 turbot/replicate)
