Embryonic day 13.5 mRNA profiles for wildtype and MIDEAS and DNTTIP1 knockout MEFs

ABSTRACT: Objective: Perform deep sequencing on mouse embryonic fibroblasts from e13.5 embryos with wildtype, MIDEAS-/- and DNTTIP1-/- genotypes to provide insights into observed embryonic lethality with associated haemolytic anaemia and heart defects. Method: Heterozygous mates of MIDEAS or DNTTIP1 set up and pregnant females culled at e13.5. MEFs were created from embryos and cultured for 4-6 passages before total RNA extraction and deep sequencing (novogene) to obtain mRNA pofiles. FastQ files processed using TRIMGALORE!, STAR, Picards remove duplicates and SAM Tools. R was used for DESeq2 analysis to find differentially regulated genes Results: A large number of both up and down regulated genes were found for both MIDEAS and DNTTIP1 knockout MEFs compared to wildtype. Of these a significant amount were common to both knockouts suggesting a role in the same complex and shared gene targets. A number of these transcripts were associated with angiogenesis and haematopoiesis as well as neual development. Conclusion: Whilst further biological experiments are required to confirm reason for haemolytic anaemia present in knockout embryos there is a strong indication this could be caused by changes in gene regulation cause by the loss of the MIDAC compex

Nos1ap constitutive null mice embryonic day 13.5 heart transcriptome

Project description:To assess the impact of Nos1ap loss on heart transcriptome during development, RNA-seq was performed in heart tissue from wildtype (males; n=5) and Nos1ap null homozygous (males; n=5) embryonic day 13.5 (e13.5) mice, and assessed for differential gene expression. At a false discovery rate of 1% and an absolute log2-fold change over 1, only two genes (Mt2 and Gm7694) were differentially expressed. These findings indicate that constitutive loss of Nos1ap has no major widespread impact on transcriptome in e13.5 hearts.

SUMO safeguards somatic and pluripotent cell identities by enforcing distinct chromatin states [SUMO-ChIP-seq]

Project description:Mouse embryonic fibroblasts (MEFs) were generated from Ubc9fl/- and Ubc9+/+ embryos (E13.5). MEFs were treated with tamoxifen for six days to cause CreERT2 activation, and induce Ubc9 floxed allele deletion. We determined the ChIP-seq profiles of SUMO-1 and SUMO-2 using chromatin of wild-type MEFs Ubc9+/+ and of the corresponding Ubc9 KO MEFs which are entirely depleted for sumoylation. The analysis revealed the nearly complete absence of genome-wide binding of SUMO-1 and SUMO-2 in Ubc9-/- MEFs, attesting for antibody specificities.

Next Generation Sequencing Analysis of Wild Type and SRSF10-/- embryonic day 13.5 heart Transcriptomes

Project description:We generated the SRSF10 -/- mice, and collected their embryonic heart at 13.5 and controls. Then, we extracted RNAs of embryonic heart and performed next generation sequencing. By comparing sequcing data from WT and SRSF10 -/- samples, we profiled the alternative splicing events and gene expression regulated by SRSF10 during mouse heart development process. E13.5 embryonic heart mRNA profiles of wild type (WT) and SRSF10-/- mice were generated by deep sequencing, using Illumina HiSeq2000.

Genome-wide profiling of the Sox chondrogenic trio at E13.5

Project description:Transgenic mice tagged with EGFP under the control of the endogenous Sox5, Sox6 and Sox9 promoter were used. E13.5 transgenic embryos were enriched for the skeletal elements and FACS was used to isolate the Sox5/6/9-expressing cells which were used for comparative expression profiling between wildtype and knockout.

Transcriptional analysis using E13.5 mouse eyes of TGFb2/GDNF mutants compared to WT

Project description:Eyes of E13.5 mouse embryos of TGFb2/GDNF knock-out mutant and wildtype (both identified by genotyping) were dissected and gene expression was compared by microarray. Coloboma were found in the mutant mice, and the time-point E13.5 was chosen to address transcriptional changes during optic fissure closure. The knock-out mutant was created from the cross of TGFbeta and GDNF single mutants (Sanford et al 1997 and Pichel et al 1996).

RNA sequencing of PIK3CA-WT/WT and PIK3CA-WT/H1047R primary mouse embryonic fibroblasts

Project description:Gene targeting was carried out by Taconic Artemis (Cologne, Germany) to introduce a point mutation resulting in conversion of CAT (H) to CGT (R) in the C-terminal p110α kinase domain, and a neo selection cassette flanked by frt sites (publication doi: 10.1038/s41467-017-02002-4). MEFs were made from PIK3CA-H1047R/WT and PIK3CA-WT/WT E13.5 embryos (4 independent MEFs per genotype), treated with 1 μM 4-OHT for one day and gathered 48h after the start of 4-OHT induction were subjected to mRNA sequencing to determine changes in gene expression upon short term PIK3CA activation in the absence of other transforming mutations. PIK3CA-H1047R/WT MEFS exhibited altered expression of 71 genes (q cutoff <0.05).

Site-specific cytosine-5 methylation by the mouse RNA methyltransferases Dnmt2 and NSun2 promotes tRNA stability and protein synthesis

Project description:Mouse embryonic fibroblast (MEFs) cell lines and liver samples from Dnmt2 and Nsun2 single mutant, double mutant and wildtype mice were used to identify potential mRNA substrates of both proteins. MEFs were derived from day 13.5 embryos and immortalized by transfection with a plasmid expressing the SV40 large-T antigen. Total RNA of MEFs cell line at passage 9 and total RNA extracted from 2 months old mouse liver tissues of Dnmt2, Nsun2 single mutant, double mutant and wildtype mice were arrayed on Illumina MouseRef8 v2 chips.

Transcription profiling of mouse wildtype or Rb-/- MEFs treated with cisplatin vs. control

Project description:The absence of the Rb tumor suppressor gene changes levels/activities of transcription factors (e.g., E2F and p53) which alter gene expression patterns, related to cell cycle control and cellular response to DNA damage. Cisplatin is a genotoxic chemotherapeutic agent and wildtype or Rb null cells have different sensitivities to cisplatin-induced cytotoxicity. We used microarrays to compare global profiles of gene expression and distinct responses of wildtype and Rb null MEFs in response to cisplatin. Experiment Overall Design: Primary wildtype or Rb null MEFs were generated from embryos at embryonic day 13.5 and cultured to passage 2. Wildtype or Rb null MEFs were either untreated or treated with 16 microM cisplatin for 24 hours prior to harvest and RNA extraction. Four different RNA samples (wildtype or Rb-/- MEFs, untreated or cisplatin-treated) were used for hybridization in triplate to Affimatrix Chips. Then, the total of 12 hybridizations were divided into 4 subseries: UT-Rb, UT-WT, CP-Rb, CP-Wt, and each subseries contained three samples (hybridization 1-3 or a-c).
