Project description:Glomerular RNA-sequencing: Shroom3 knockdown adult mice vs controls
2018-12-26 | GSE110092 | GEO
Project description:BACKGROUND:We previously showed that the presence of a CKD-associated locus in SHROOM3 in a donor kidney results in increased expression of SHROOM3 (an F-actin-binding protein important for epithelial morphogenesis, via rho-kinase [ROCK] binding); this facilitates TGF-b signaling and allograft fibrosis. However, other evidence suggests Shroom3 may have a protective role in glomerular development. METHODS:We used human data, Shroom3 knockdown podocytes, and inducible shRNA-mediated knockdown mice to study the role of Shroom3 in adult glomeruli. RESULTS:Expression data from the Nephroseq database showed glomerular and nonglomerular SHROOM3 had opposing associations with renal function in CKD biopsy samples. In human allografts, homozygosity at rs17319721, the SHROOM3 locus linked with lower GFR, was associated with reduced albuminuria by 2 years after transplant. Although our previous data showed reduced renal fibrosis with tubular Shroom3 knockdown, this study found that glomerular but not tubular Shroom3 knockdown induced albuminuria. Electron microscopy revealed diffuse foot process effacement, and glomerular RNA-sequencing showed enrichment of tyrosine kinase signaling and podocyte actin cytoskeleton pathways in knockdown mice. Screening SHROOM3-interacting proteins identified FYN (a src-kinase) as a candidate.We confirmed the interaction of endogenous SHROOM3 with FYN in human podocytes via a critical Src homology 3-binding domain, distinct from its ROCK-binding domain. Shroom3-Fyn interaction was required in vitro and in vivo for activation of Fyn kinase and downstream nephrin phosphorylation in podocytes. SHROOM3 knockdown altered podocyte morphology, cytoskeleton, adhesion, and migration. CONCLUSIONS:We demonstrate a novel mechanism that may explain SHROOM3's dichotomous associations in glomerular versus nonglomerular compartments in CKD.

Project description:Fyn kinase has been implicated in multiple behavioral responses to ethanol and in the regulation of myelin gene expression. Here we tested whether Fyn kinase modulated basal or ethanol-responsive expression of genes regulated by acute ethanol in brain regions of the mesolimbocortical dopamine pathway. Using expression profiling, we sought to define Fyn-dependent gene networks underlying ethanol behavioral traits; with emphasis on ethanol-induced loss of righting reflex (LORR) due to the reproducible association of Fyn kinase genotype with this behavioral phenotype (Miyakawa et al., 1997, Boehm et al., 2003, Yaka et al., 2003, Boehm et al., 2004b). Our expression profiling and bioinformatics results suggest multiple Fyn-related mechanisms, especially those affecting a network of myelin-related gene expression within the medial PFC, as contributing to the sedative-hypnotic properties of ethanol. Variation in the expression of these Fyn-dependent gene networks may be critical molecular endophenotypes affecting the behavioral level of response to acute ethanol, and subsequently, the long-term risk for alcohol use disorders. Adult male control (B6129SF2/J) and Fyn-kinase null (B6;129S7-Fyntm1Sor/J) mice were treated with saline or ethanol (3.0 g/kg x 4 hours) and brain regions harvested by microdissection for total RNA expression profiling by Affymetrix microarrays. Samples were randomly assigned to batch groups prior to total RNA extraction, cRNA synthesis and hybridization. Each microarray represents a pooling of 3 animals and 3 arrays were analyzed per treatment group for a total of 12 arrays per brain region. Statistical and bioinformatics analysis was used to identify Fyn-dependent effects on basal and ethanol-responsive gene expression, with a particular focus on myelin-related gene expression. This series of samples includes medial prefrontal cortex (PFC).

Project description:FYN-TRAF3IP2 expression in hematopoietic progenitors induces T cell transformation in mice and cooperates with loss of the Tet2 tumor suppressor in PTCL development. To investigate the oncogenic activity of FYN-TRAF3IP2, we analyzed the lymphomagenic effects of expressing this gene fusion alone and in cooperation with loss of the Tet2 tumor suppressor gene in vivo. In these experiments, we first infected hematopoietic progenitors from CD4-specific tamoxifen-inducible Cre Tet2 conditional knockout mice (CD4 Cre-ERT2, Tet2fl/fl) with bicistronic retroviruses expressing wild type TRAF3IP2 and GFP, FYN-TRAF3IP2 and GFP, or GFP alone and injected these intravenously into isogenic recipients. Transplanted mice were then treated with vehicle only, to test the oncogenic effects of TRAF3IP2, FYN-TRAF3IP2 or GFP expression; or with tamoxifen, to evaluate the effects of TRAF3IP2, FYN-TRAF3IP2 or GFP expression in concert with genetic loss of Tet2 in CD4 T cells. In this setting, all animals transplanted with GFP-expressing progenitors remained lymphoma free at the end of follow up and one animal transplanted with wild type TRAF3IP2 GFP expressing cells developed a CD8+ T cell lymphoma. In contrast, 4/10 (40%) vehicle treated mice transplanted with FYN-TRAF3IP2-expressing cells and 5/10 (50%) tamoxifen treated mice transplanted with FYN-TRAF3IP2-expressing cells developed clonal CD4-restricted mature T cell lymphomas. To further analyze the lymphomagenic effect of the fusion gene, we performed transcriptomic profiling of FYN-TRAF3IP2-induced mouse CD4+ GFP+ PTCL tumor lymphocytes compared with normal mouse CD4+ T cells by RNAseq.

Project description:We investigated influence of CMTR1 phosphorylation by CK2 on RNA expression. In this experiment, we added wild-type and phosphorylation deficient mutant of CMTR1 and knocked out the endogenous CMTR1. We demonstrated that lack of phosphorylation of CMTR1 affects only small but specific group of genes.
