Double knock-in pig models with elements of binary Tet-on and phiC31 intergrase systems for controllable and switchable gene expression

ABSTRACT: In summary, we have for the first time generated a Dox inducible and switchable tdTomato pig strain with dual knock-in at Hipp11 and Rosa26 locus. This pig model provide a versatile tool model to produce stable transgenic pigs with inducible overexpressing any gene of interest by using the technology of phiC31 integrase-mediated cassette exchange. Based on this approach, an inducible hKRASG12D-expressing pig model line was established and tumor formation was induced after Dox administration. We expect that the inducible tool pig model would greatly facilitate the production of controllable transgenic pigs, and broaden the applications of transgenic pigs in biomedicine and agriculture fields.

Gene expression profile of miniature pig as animal model for toxicity evaluation by using mRNA expression profiling.

Project description:Miniature pig is a useful animal model to clarify the vital reaction and the molecular mechanisms. However, physiclogical response of pig model to sodium azide (AZIDE) stress is not reveal. To establishment of large animal model for evaluate toxic stress, whole blood of miniature pig were assessed with genomics. 7 month old clawn miniature pigs were fed AZIDE feeding. AZIDE dose of 300Âµg/kg, one hundredth of LD50 was given orally to the miniature pigs. Whole blood gene expression was measured at 0h, 6h and 24h after feeding.

Generation and Characterization of Stable Pig Pre-gastrulation Epiblast Stem Cell Lines [ChIP-seq]

Project description:Despite ongoing attempts since the 1990s, no stable embryonic stem cell line has been established in pigs. Here, guided by insights from large-scale single-cell RNA-sequencing profiling of pig embryos from embryonic day (E) 0 to E14, we developed an in vitro culture system for establishing and maintaining stable pluripotent stem cell lines from pig E10 pre-gastrulation epiblasts (pgEpiSCs). Enabled by chemical inhibition of WNT-related signaling in culture, the pgEpiSCs maintain their pluripotency and normal karyotypes after more than 200 passages. Strikingly, ultra-deep in situ Hi-C analysis revealed functional impacts of 3D-spatial associations on the transcriptional regulation of pluripotency marker genes in the pgEpiSCs. Practically, we confirmed that the pgEpiSCs can readily tolerate at least three rounds of successive gene editing and generated cloned gene-edited live piglets. Our findings deliver on the long-anticipated promise of large model animal stem cells and open new avenues for biological research, animal husbandry, and biomedicine.

Development of oligonucleotide microarray to study global gene expression profile in guinea pigs in response to tuberculosis infection

Project description:In this study we developed a guinea pig oligonucleotide microarray (GPOM) comprising of a total number of 45,220 features including 43,803 valid features from different mammalian species. These features are inclusive of 2971 newly annotated probes corresponding to 344 unique genes of guinea pig. As a case study, we utilized this array to examine the gene expression profile in guinea pig lungs in response to infection with Mycobacterium tuberculosis. Studying the global gene expression profile in guinea pigs allowed identification of the disease signature of pulmonary TB infection represented by several unique genes that are differentially regulated in this model. While, 1344 unique genes exhibited marked up regulation, 1856 genes were significantly down regulated. The newly developed tool not only finds its utility in studying the global gene expression profile associated with vaccination and/or M. tuberculosis infection in this highly useful animal model but would also be immensely useful in identification of new drug targets, testing of therapies, molecular genetic analysis for diseases other than tuberculosis as well. Genotypic Technology designed Custom Cavia porcellus 4x44k Gene Expression Array (Agilent-AMADID-019424) * In order to validate the GPOM developed in this study, we compared the gene expression profile of guinea pig lungs at 10 weeks post- M. tuberculosis infection with respect to that obtained from normal uninfected animals. To address this, guinea pigs were aerosol infected with M. tuberculosis, lungs were harvested at 10 weeks post-infection and RNA obtained from infected lungs was employed for cDNA synthesis and microarray hybridization. The gene expression was compared with the RNA sample obtained from the lungs of normal uninfected guinea pigs.

Analysis of Wild Type and Leptin-overexpressing Pig PBMC Transcriptomes

Project description:Purpose: To find the difference between leptin-overexpressing and wt pig. Methods: Peripheral blood mononuclear cells (PBMCs) mRNA profiles of 6-month-old wild-type (WT) and leptin-overexpressing pig were generated by deep sequencing. Sequencing libraries were constructed according to the protocol for the Illumina TruSeq Sample preparation kit. Sequencing was performed on the Illumina X Ten sequencer. Library construction and sequencing were performed at the Genergy Biotech Co., Ltd. (Shanghai). Results: RNA-seq was performed to detect the transcriptomic changes in PBMCs in the transgenic leptin pigs. With 2-folds change and p<0.05 threshold, we found that 84 transcripts were upregulated, and 124 transcripts were downregulated in the transgenic leptin pigs. Conclusions: The leptin-overexpressing pigs exhibited remarkable resemblance to human SLE in multiple aspects of the disease.

Progression of liver tumor was promoted by tris(1,3-dichloro-2-propyl)phosphate through the induction of inflammatory responses in krasV12 transgenic zebrafish

Project description:In this study, krasV12 genetically modified zebrafish, Tg(fabp10:rtTA2s-M2; TRE2:EGFP-krasG12V), an inducible liver tumor model, was used to evaluate the promotion potential of TDCIPP for liver tumor. Briefly, krasV12 transgenic females were exposed to 0.3 mg/L TDCIPP, 20 mg/L doxycycline (DOX) and a binary mixture of 0.3 mg/L TDCIPP with 20 mg/L DOX, and liver size, histopathology, and transcriptional profiles of liver were tested. Treatment with TDCIPP increased the liver size and caused more aggressive hepatocellular carcinoma (HCC). Furthermore, compared with the exposure to DOX, TDCIPP in the presence of DOX up-regulated the expression of genes relevant with salmonella infection and the toll-like receptor signaling pathway, implying an occurrence of inflammatory reaction, which was sustained by the increase in the amount of infiltrated neutrophils in the liver of Tg(lyz:DsRed2) transgenic zebrafish larvae. Collectively, our results suggested that TDCIPP could promote the liver tumor progression by induction of hepatic inflammatory responses.

CGH analyses for the Chinese indigenous pig breeds and commercial pig breeds [Agilent]

Project description:Since CNVs play a vital role in genomic studies, it is an imperative need to develop a comprehensive, more accurate and higher resolution porcine CNV map with practical significance in follow-up CNV functional analyses To detect CNV of pigs, we performed high density aCGH data of diverse pig breeds in the framework of the pig draft genome sequence (Sscrofa10.2) 9 Chinese indigenous pig, one Chinese wild boar and 2 commercial pigs were detected using one pig of Duroc as reference. These 12 animals include 1 wild pig, 2 pigs each from Yorkshire and Landrace as the representatives of modern commercial breeds and 9 unrelated individuals selected from 6 Chinese indigenous breeds (2- Tibetan pig, 2- Diannan small-ear pig, 2-Meishan pig, 1- Min pig, 1-Daweizi pig, and 1-Rongchang pig).
