Project description:This experiment tests the effects of alcoholism by examining the primary metabolites obtained from mouse stool. Stool was collected from 4 groups of mice with varying treatments. One group was not humanized, another was humanized from a healthy human, a third was humanized from a current drinker, and the final group was humanized from a current drinker but also given a treatment of LGG. Humanizations were done to create a model of human gut activity in the mice.
Project description:To make the human liver accessible to metabolic treatments, we employed a liver-specific humanized mouse model in which approximately 50% of the mouse hepatocytes were replaced by human ones. To capture transcriptomes reflecting pathophysiology and therapeutic development of metabolic diseases, we subjected the humanized mice to the key metabolic transcriptional factor agonist treatments. We then performed gene expression profiling analysis using data obtained from RNA-seq of these humanized mice.
Project description:In this study, we compared the metabolic effects of TCPOBOP using lipidomic, transcriptomic, and proteomic analyzes in wild-type and humanized CAR-PXR-CYP3A4/3A7 mice. In the humanized mouse model, human CAR retains its constitutive activity in metabolism regulation; however, it is not significantly activated by TCPOBOB. TCPOBOP elevated serum and liver levels of triglycerides and promoted hepatocyte hypertrophy in humanized CAR mice. Hepatic lipidomic analysis revealed a significant accumulation of triglycerides and downregulation of its metabolites in humanized CAR mice. RNA-seq analysis has shown gene expression changes mainly involved in lipid metabolic processes and in ppar, leptine, thyroid, and circadian clock pathways. In summary, we identify TCPOBOP as a lipid metabolism disruptor in humanized CAR mice
Project description:By taking advantage of the highly immunogenic live-attenuated yellow fever virus vaccine YFV-17D, we performed an in-depth comparison of transcriptomic responses in human vaccinees, conventional humanized mice, and second generation humanized mice. We demonstrate that selective expansion of human myeloid and natural killer cells in humanized mice promotes transcriptomic responses akin to those of human vaccinees
Project description:To elucidate the effect of human specific one amino acid substitution of Nova1 (I197V) in mice, gene expression profiling analysis was performed using humanized Nova1 mice (NOVA1hu/hu) and their littermate control mice (NOVA1wt/wt).
Project description:In order to identify genes expressed by cells that leave the spleen, the spleens were harvested from untreated reconstituted humanized mice (N=4) and a single cell suspension was prepared . The cultures were treated with either teplizumab (anti human CD3 hOKT3g1(Ala-Ala)) or hIg for 18 hrs in vitro. Splenocytes were also harvested 18 hrs after reconstituted mice (N=4) were treated with teplizumab in vivo. The humanized mice used where NOD/SCID IL2gc-/- (NSG) reconstituted with human CD34+ at birth. Total RNA was obtained form sorted human CD4 splenocytes 18 hours post treatment. Comparsons were made between the treatment groups.
