Project description:This experiment aimed to characterise transcriptomes of plasmid-based mouse models of liver cancer, hepatotoxin-induced chronic liver injury and the combination thereof. In detail, C57BL/6JAusb mice received hydrodynamic tail vein injection (HTVI) of plasmids encoding Sleeping Beauty transposase (SB), alone or in combination with transposon plasmids encoding myristylated AKT1 (AKT), c-Met and NRasV12 (NRas), previously characterised by Ho et al. (2012) (Hepatology 55(3):833-45) and Hu et al. (2016) (Sci Rep 6:20484). 8-10 days post-HTVI, mice began biweekly intraperitoneal (i.p.) injections of saline or the hepatotoxin thioacetamide (TAA), 10-11 doses.
Project description:We performed survival analysis of control and MCD groups, and explored underlying tumor suppression mechanisms after dietary intervention, focused on alterations in the energy-dependent signaling pathways, histone modifications, and global gene expression differences on cDNA microarray study. Five- week- old male C57BL6 mice were randomly divided into two groups and fed control diet (control group, LabDiet, Brentwood, MO, USA) or moderate restriced carbohydrate diet formula (MCD, Treat group) in a specific pathogen free zone. All procedures were approved by the institutional animal use and care committee. Following a preliminary feeding of each diet formula for two week, HrasG12V / shp53 / GFP4 gene containing transposon vector were injected into mouse tail vein by hydrodynamic injection method. After 4 weeks of diet supplementation, all mice were sacrificed. Mouse liver tissue was excised for microarray analysis.
Project description:In this study, we identified and validated a molecular classification of hepatocellular carcinoma (HCC) patients based on 42 fatty acid degradation (FAD) genes. The F1 subtype was characterized by the lowest expression of FAD genes, whereas F3 subtype had the highest expression levels, and F2 had the intermediate expression levels of FAD genes. We characterized the immune microenvironment in HCC patients from different FAD subtypes. To further explore the immune landscape of HCC, we generated the Nras-driven HCC model (belonging to the F1 subtype) and the Akt1-driven HCC model (belonging to the F3 subtype) by hydrodynamic tail vein injection (HTVi) of oncogenes together with the sleeping beauty transposase. The tumor tissues were resected from the liver 14 weeks after the hydrodynamic delivery of the plasmids, isolated for single cells, and prepared for scRNA-seq.

Project description:Control group: 250 g adult male rats injected with normal saline through tail vein; Experimental group: 250 g adult male rats injected with E. coli suspension through a tail vein
Project description:Control group: injected with normal saline through tail vein; Experimental group: injected with Escherichia coli//Staphylococcus aureus suspension through a tail vein
Project description:In order to check the tumorigenic property of TAF2, either alone or in combination with MYC, we used Sleeping Beauty (SB) transposase-mediated somatic integration in combination with hydrodynamic tail vein injection (HTVI) technique in FVB mice. TAF2 alone did not induce tumor, MYC overexpression induced tumors at a variable levels, while both TAF2 and MYC overexpression resulted in profound development of HCC.
Project description:We investigated YAP/AKT hydrodynamic tail vein injected murine models and we analyzed the correlative change of immune cell profile and stemness during cholangiocarcinoma progression using single-cell RNA sequencing
