Project description:We compared RNA expression profiles of wild type of mice maintained on high fat diet or Irs1/2:foxo1-LTKO mice infected with Fst288 AAV-TBG virus Fst288-AAV-TBG infection modestly up- or down-regulated the expression of many genes, including several related to hepatic glucose metabolism (Pck1, G6pc and Gck) (Fig. S8a); qPCR confirmed that Fst288AAV•TBG affected the expression of these and other genes during both fasting (Pck1, G6pc and Gck) and feeding (Foxo1, Igfbp1, Pck1, and Ppargc1a)
Project description:To explore the effect of Bicd2 in Con A-induced acute autoimmune hepatitis, we conducted single cell RNA sequencing of AAV-scramble or AAV-shBicd2 infected mice livers in response to Con A injection.
Project description:To explore how Mier1 affects liver regeneration, we specifically knocked out Mier1 in mouse liver through adeno-associated virus (AAV). The mice we used were knocked in a Cre-induced Cas9 expression cassette. Through tail vein injection, we delivered the AAV expressing Cre-recombinase under TBG promoter, and sgRNA targeting Mier1 (AAV-Mier1 sgRNA), into the adult Cas9 knockin mice to knock out the Mier1 gene in liver. AAV vectors with no sgRNA inserted (AAV-Cre) were used in control animals. To assess the role of MIER1 in liver regeneration, we performed 70% partial hepatectomy, 3 weeks after AAV injection. We then performed ATAC-seq in Control and Mier1 liver-sepcific knockout mice liver tissues at 0 h and 24 h after PHx to explore the influence of Mier1 on the chromation opening during liver regeneration.
Project description:Analysis of changes in gene expression following hepatocyte specific deletion of GATA4 in adult mice. Results showed that the subset of differentially expressed genes had liver specific ontologies. Total RNA isolated from hepatocytes of AAV8-Tbg-Cre injected GATA4 fl/fl mice was compared to total RNA isolated from AAV-Tbg-GFP injected GATA4 fl/fl mice.
Project description:Analysis of changes in gene expression following hepatocyte specific deletion of GATA4 and GATA6 in adult mice. Results showed that the subset of differentially expressed genes had liver specific ontologies. Total RNA isolated from hepatocytes of AAV8-Tbg-Cre injected GATA4,6 fl/fl mice was compared to total RNA isolated from AAV-Tbg-GFP injected GATA4,6 fl/fl mice.
Project description:To investigate the role of the RNA-binding protein LARP1 and its interaction with ribosomal protein mRNAs in regenerating neurons, we performed total RNA and RiboTag sequencing analysis using AAV-Control or AAV-shLarp1 infected sensory neurons using RiboTag mice, RPL22HA+/+;Advillin-Cre+.
Project description:To investigate the role of the Gpr151 mRNA and its interaction with ribosomal protein mRNA operon in regenerating neurons, we performed total RNA and RiboTag sequencing analysis using AAV-Control or AAV-shGpr151 infected sensory neurons using RiboTag mice, RPL22HA+/+;Advillin-Cre+.
Project description:Peripheral neurons can regenerate after nerve injury. To investigate the role of the RNA-binding protein CSDE1 and its interaction with ribosomal protein mRNAs in regenerating neurons, we performed total RNA and RiboTag sequencing analysis using AAV-Control or AAV-shCsde1 infected sensory neurons using RiboTag mice, RPL22HA+/+;Advillin-Cre+.
Project description:After discovering that Gpr151 mRNA regulates the CSDE1-mediated rp-mRNA operon, we designed an engineered version of the 5'UTR of Gpr151 mRNA(e5'UTR), which has an enhanced interaction with CSDE1. To determine if this e5'UTR RNA can restore the down-regulated rp-mRNA operon formation in Gpr151 knockdowned neurons, we performed total RNA and RiboTag sequencing analysis using AAV-shGpr151 or AAV-shGpr151 with AAV-e5'UTR infected sensory neurons using RiboTag mice, RPL22HA+/+;Advillin-Cre+.
