Characterization of novel endothelial-specific and smooth-muscle specific Poldip2 knockout mice

ABSTRACT: Poldip2 is a multifunctional protein whose roles are only partially understood. The previous Poldip2 knockout mouse generated by the gene trap model suffers from two limitations: perinatal lethality in homozygotes and constitutive Poldip2 inactivation. To overcome these limitations, we developed a new conditional floxed Poldip2 mouse. Here, we correctly targeted floxed Poldip2 mice to produce an endothelial-specific by crossing it with CDH5 ERT2 Cre mouse. Additionally, we also produced smooth-muscle specific Poldip2 knockout mice by crossing the flox'ed Poldip2 mice with SM22A-Cre mice. The Poldip2_EC-/- and Poldip2_SMC-/-mice were viable and showed remarkably reduced Poldip2 expression. To characterize the effect of Poldip2 ablation in the ECs and in the SMCs, we performed a RNA-seq study using the carotid arteries of these mice.

Characterization of novel whole body Poldip2 knockout mice generated by [Precisely "flox"ing Poldip2 gene] and crossing with Cre deleter mice

Project description:Poldip2 is a multifunctional protein whose roles are only partially understood. The previous Poldip2 knockout mouse generated by the gene trap model suffers from two limitations: perinatal lethality in homozygotes and constitutive Poldip2 inactivation. To overcome these limitations, we developed a new conditional floxed Poldip2 mouse. Here, we correctly targeted floxed Poldip2 mice to produce a new constitutive knockout line by crossing with a Cre deleter. In contrast to the gene trap model, many homozygous knockout mice were viable, in spite of having no Poldip2 expression. To characterize the effect of Poldip2 ablation in the vasculature, we performed a RNA-seq study using the carotid arteries of these mice.

Expression data from AEG-1fl/fl and AEG-1DHEP mice which have conditional hepatocyte-specific knockout of AEG-1 (Astrocyte elevated gene 1)

Project description:AEG-1 is overexpressed in human hepatocellular carcinoma (HCC) and positively regulates development and progression of HCC A conditional hepatocyte-specific knockout mouse was generated by crossing floxed AEG-1 mouse with Alb/Cre mouse in C57BL/6 background

Myocardial-specific ablation of Jarid2 leads to dilated cardiomyopathy in mice

Project description:Analysis of heart from myocardil specific deletion of Jarid2 by crossing Jarid2 floxed mice with aMHC-Cre mice (Jarid2-aMHC). Jarid2-aMHC mice regult in dilated cardomyopathy and reveal premature death. To identify differentially expressed genes in Jarid2-aMHC hearts, we performed RNA-seq analysis on mutant hearts and control heart at postnatal day 10 (P10) and 7 months of ages (7M).

UPF2 establishes testis-specific transcriptome enriched in transcripts with shorter 3’UTRs

Project description:This report not only adds a novel mechanism to the current dogma on achieving global shortening of 3'UTRs, but also unveils a novel function of the NMD pathway in establishing tissue-specific transcriptome identity We first generated prospermatogonia-specific Upf2 conditional knockout mice (Ddx4-Cre; Upf2 fl/Δ, hereafter called Ddx4-KO) by crossing Ddx4-Cre13 with Upf2 floxed.

Transcription profiling of mouse dorsal root ganglia after diphtheria-toxin deletion of the Nav1.8-expressing cells using the cre/loxP system

Project description:Comparison of transcript levels after diphtheria-toxin deletion of the Nav1.8-expressing cells using the cre/loxP system.<br> Pain requires input from nociceptors which are specialised peripheral sensory neurons in dorsal root ganglia (DRG). To explore the nociceptor-specific mRNA profiles, we used microarray analysis to examine the altered repertoire of genes expressed in DRG from mice depleted of Nav1.8-expressing neurons which are mainly nociceptors. To generate the animal, a Nav1.8 knock-in Cre-expressing mouse (Nav1.8-Cre) was used to excise a floxed stop upstream of globally expressed diphtheria toxin A-subunit gene (ROSA26-eGFP-DTA). By crossing heterozygous Cre mice with homozygous toxin-expressing floxed mice, experimental toxin-expressing (DTA) mice, in which DTA expressing nociceptors had been deleted, were generated. 6 DTA mice and 6 litter mate controls were used for microarray analysis. 3 Affymetrix Mouse Genome 430 2.0 Array chips were employed for analysis of the gene transcripts of each conditions.

Adult-induced cardiac-specific knockout of Parkin provokes minimal transcriptional effect

Project description:Adult mice bearing homozygous floxed Parkin alleles (PMIDs 15249681, 21376232; T M Dawson), with or without the Myh6-driven MERCreMER transgene, were administered tamoxifen at 6-10 wks of age. Tissues were obtained from euthanized mice 9-10 weeks after tamoxifen induction. 6 floxed, non-Cre (noninduced) mouse hearts; 6 floxed, MERCreMer, adult-induced, Parkin knockout mouse hearts

Genes regulated by HEB and E2A during DP stage of thymocyte development

Project description:To investigate gene targets of the E-proteins HEB and E2A during the CD4+CD8+ double positive (DP) stage of T cell development. We examined E-protein function by simultaneous removal of both HEB (Tcf12) and E2A (Tcfe2a) genes at the DP stage. This was done by crossing mice containing HEB floxed and E2A floxed alleles to a CD4Cre background (Tcf12f/fTcfe2af/fCD4Cre mice). Microarray analysis was used to compare gene expression in HEB and E2A double deficient DP thymocytes (Cre+) to Cre- control DP thymocytes. Keywords: genetic modification

The Cyld gene was conditionally inactivated specifically in the liver by crossing mice carrying floxed exon 9 allele of Cyld with Alfp-Cre transgenic mice. Liver RNAs from Cyld lox/lox-AlfpCre mice were compared with RNAs prepared from the livers of wild type littermates.

Project description:We studied CGNPs with conditional deletion of Eed using scRNA-seq. Eed was deleted in CGNPs by crossing Math1-Cre mice with Eed floxed mice. scRNA-seq seq was performed by Drop-seq. The results may be compared to our prior published data on scRNA-seq in normal CGNPs (GEO accession number GSE129730)

Mouse retina from Msi1/Msi2 double knockout in photoreceptor cells

Project description:This quantitative protepomics study (TMT10 isobaric labeling) of the protein expression in the retina of Msi1/Msi2 double knockout mouse compared to floxed controls. The Msi1 and Msi2 genes were knocked out in photoreceptor cells using tamoxifen inducible Cre (Cre-ERT2) under the control of Pde6g promoter. Tamoxifen was administered by intrapertoneal injection for three consecutive day starting at postnatald day 30, and the retina was collected at postnatal day 51. Retinas from floxed animals lacking the Cre recombinase and treated with tamoxifen were used as controls. Five biological replicates for each knockout (three femailes, two males) and control (two femaes and three males) group were used.
