Project description:Tax1-binding protein 1 (Tax1bp1) negatively regulates NF-κB by editing the ubiquitylation of target molecules with its catalytic partner A20. Genetically engineered TAX1BP1-deficient (KO) mouse develops age-dependent inflammatory constitution in multiple organs including heart, liver, skin and succumb to premature heart failure. Laser capture dissection and gene expression microarray analysis on the mitral valves of TAX1BP1-KO mice (8 and 16 week old) revealed that the 588 transcription alterations. SAA3 (serum amyloid A3), at 1,180-fold induction (FI), CHI3L1(361-FI), HP(187-FI), IL1B(122-FI) and SPP1/OPN(101-FI) and WIF1 (Wnt inhibitory factor 1) at 11-fold decrease implied extensive inflammation and tissue degeneration at this microenvironment. Intense Saa3 staining and significant reduction of I-κBα at the same area, massive infiltration of inflammatory lymphocytes and edema formation at the peripheral areas of sinoatrial and atrioventricular node were also observed and electrocardiogram indicated atrioventricular conduction defect (elongated PQ-interval) in TAX1BP1-KO mice. Since antibiotics-induced ‘germ free’ status for three months significantly ameliorated these chronic autoimmune and altered cardiac excitation properties, we conclude that these chronic pathological conditions, as we named ‘pseudo-infective endocarditis’ were boosted by the commensal microbiota those who are usually harmless by their nature. This experimental outcome raises a novel mechanistic linkage between endothelial inflammation and cardiac dysfunction. We employed laser capture microdissection (LCM) and gene expression microarray technique to obtain the specific gene expression information of pathologic organ. Total RNAs of mitral valves from three independent tissues of 8- or 16-week age (-wk) male mice of either WT or TAX1BP1-KO mice were prepared by LCM followed by total RNA extraction kit. Then the global mRNA expression profiles were analyzed by Agilent gene expression microarray.

Project description:Selective autophagy receptor can combine with substrate in cells to degrade them and maintain cellular homeostasis. TAX1BP1, a kind of selective autophagy receptor, has N-terminal SKIP carboxyl homology (SKICH) domain (LC3-Interacting Region) and a C-terminal ubiquitin binding domain (UBD).TAX1BP1 can also be a potential regulatory factor to influence macroautophagy initiation. In order to research the function of TAX1BP1in renal tubular epithelial cells, we knockout and over expressive TAX1BP1 in HK-2 cells and research the state of autophagy flow and senescence. We found that TAX1BP1 knockout could impair initiation of autophagic flow, causing obstruction in LC3 lipidation. Farther, TAX1BP1 knockout could bring senescence and sensitivity in damage factor.

Project description:The G2019S mutation in leucine-rich repeat kinase 2 (LRRK2) causes familial Parkinson's disease (PD) and is also found in a subset of idiopathic cases. Prior studies in Drosophila and human induced pluripotent stem cell (iPSC)-derived dopamine neurons uncovered a pronounced effect of G2019S LRRK2 on mRNA translation. It was previously reported that G2019S LRRK2 promotes translation of mRNAs with complex 5' untranslated region (UTR) secondary structure, resulting in increased expression of calcium channels and dysregulated calcium homeostasis in human dopamine neurons. Here, we show that dysregulated translation occurs in the brains of mammalian LRRK2 models in vivo Through ribosome profiling studies of global translation, we observe that mRNAs with complex 5'UTR structure are also preferentially translated in the G2019S LRRK2-expressing mouse brain. Reporter assays suggest that this 5'UTR preference is independent of translation initiation factors. Conversely, translation of mRNAs with complex 5'UTR secondary structure is downregulated in LRRK2 knock-out (KO) mouse brain, indicating a robust link between LRRK2 kinase activity and translation of mRNA with complex 5'UTR structure. Further, substantia nigra pars compacta (SNpc) dopamine neurons in the G2019S LRRK2-expressing brain exhibit increased calcium influx, which is consistent with the previous report from human dopamine neurons. These results collectively suggest that LRRK2 plays a mechanistic role in translational regulation, and the G2019S mutation in LRRK2 causes translational defects leading to calcium dysregulation in the mammalian brain.

Project description:Purpose: The goal of this study is to identify genes and molecular pathways whose expression is altered in the livers of Gpr151 knock-out (KO) mice compared to Gpr151 wild-type (WT). Methods: Total RNA was isolated from livers of fasted (5h) 16-week-old male mice. Deep sequencing of RNA from three wild-type and three knock-out mice was done using the mRNA-Seq pipeline at Novogene. The sequence reads that passed quality filters were aligned to the mouse GRCm38.p6 genome using STAR 2.6.1d. Differential expression testing was conducted using DESeq2. Results: Using an optimized data analysis workflow, we mapped about 40 million sequence reads per sample to the mouse genome (build mm10) and identified 54,532 transcripts in the livers of Gpr151 WT and KO mice. RNA-seq data identified 79 transcripts which were significantly upregulated in KO (p-adj < 0.05, log2FoldChange>1) and 338 transcripts which were significantly downregulated (p-adj<0.05, log2FoldChange<-1) in KO. Conclusions: Our study represents the first detailed analysis of the liver transcriptome of Gpr151 KO mice.
