MicroRNA-sequencing from the striatum of ELAVL4 (HuD) KO mice and wild type littermate adult mice

ABSTRACT: Purpose: The goals of this study are to determine how deletion of the RNA-binding protein HuD affects the levels of microRNAs in the striatum of Elav4 (HuD) KO using miRNA-seq Methods: Total RNA from striatum of male adult Elavl4 (HuD) KO and wild-type (WT) littermates (n=3 per genotype) crossbred to C57Bl/6 for more than 10 generations were analyzed by small RNA sequencing, in triplicate, using an Illumina NextSeq platorm. The percentage of the number of bases with Q >30 for all 6 samples were >93%. Results: Using an optimized data analysis workflow (see diagram below), about 6.3 million sequence reads per HuD KO sample and 3.3 million per WT sample were mapped miRBase v22. The expression level (Reads count) of miRNAs were calculated using miRDeep2. The number of identified miRNA per group was calculated based on the mean of CPM in group > 1. Conclusions: We found 309 miRNAs from 54 unique families (FC>1.75- and p<0.05) were significantly upregulated while 161 miRNAs from 143 unique families (FC<0.55 and p<0.05) were significantly downregulated in the striatum of HuD KO mice vs WT samples.

HuD interacting circular RNAs in the mouse striatum

Project description:This study explores whether HuD could bind to and regulate the expression circRNAs from genes associated with neuronal development and synaptic plasticity circRNAs bound to HuD were isolated from the striatum of HuD-OE mice by RNA immunoprecipitation (RIP) as described in Bolognani et al, 2010 (https://doi.org/10.1093/nar/gkp863) using Dynabeads® (Thermo Fisher Scientific) coated with mouse monoclonal anti-myc tag antibody (9B11; Cell Signalling Technology Inc.) specifically recognizing myc-tagged HuD transgenic protein expressed in HuD-OE as described before (Bolognani et al., 2010; Zimmerman et al., 2020). Controls for RIP assays were performed using either non-immune IgG and HuD-OE tissue or the myc-tag antibody and wild type (WT) tissue.

Transcriptional profiling of striatum from a zQ175 KI mouse model of Huntington's disease with or without homozygous knockout of the Msh3 gene

Project description:Previous studies have suggested a strong association between lower MSH3 expression, reduced somatic repeat expansion, and slower disease onset and progression. The effects of a homozygous knock-out in the Msh3 gene on transcriptome phenotypes in striatum in six-month-old WT and zQ175 mice were studied. Striatum was isolated from 6-month-old mice. Transcriptomic analysis (RNASeq) was performed on four genotypes with 8 replicates per genotype: WT (WT for Htt and Msh3), zQ175 (zQ175 for Htt, WT for Msh3), WT.Msh3.HOM (WT for Htt, Homozygous for Msh3 KO), and zQ175.Msh3.HOM (zQ175 for Htt, Homozygous for Msh3 KO).

High Mobility Group protein HMGB2 is a Critical Regulator of Plasmodium Oocyst Development

Project description:Two mice per group were infected with one million purified schizonts from the WT and two clones (B3 and D1) of the pyhmgb2 KO lines. Parasitemia reached 10 to 20 % and equivalent gametocytemia total RNA was extracted from the WT and the B3 and D1 clones of the KO parasite lines using the Trizol method on saponin lysed of parasites.

RNA Sequencing analyses of control and HuD KO (Elavl4 null) mouse cortical transcriptomes

Project description:Purpose: The goal of this study was to analyse RNA-seq data to determine the effect of deletion of the RNA-binding protein HuD in transcriptiome-wide alternative splicing and polyadenylation in the neocortex of adult HuD KO vs. wild type littermates (controls) Methods: Cortical mRNA profiles of adult HuD KO (Elavl4 -/-) mice and Control mice were generated by RNA sequencing, in triplicate, using Illumina NovaSeq 6000 platform. The quality of raw RNA-sequencing reads was evaluated using FastQC software (version 0.11.5) and adapters were removed using the Cutadapt (version 1.15) and Trimmomatic (version 0.38) software. Alternative splicing was evaluated using rMATS software (version 4.0.2) and BAM files were converted to BedGraph before examining alternative polyadenylation using DaPars software (version 0.9.1) Methods (cont.): RNA-seq data was aligned to the M musculus genome (UCSC browser, mm10) using STAR (version 2.7.3a), and MultiQC (version 1.8) was used to perform a final quality check on STAR alignment files. If alignments were found to be the same read length and have >80% reads mapped to a unique location, the data was considered good quality and alternative splicing and polyadenylation analyses were performed. Sequence reads per sample were aligned to the mouse genome (build mm10). Results: HuD KO affected alternative splicing of 310 genes, including 17 validated HuD targets such as Cbx3, Cspp1, Snap25 and Gria2. In addition, deletion of HuD affected polyadenylation of 53 genes, with the majority of significantly altered mRNAs shifting towards usage of the proximal polyadenylation signal (PAS), resulting in shorter 3’ untranslated regions (3’ UTRs). Conclusions: HuD KO had a greater effect on alternative splicing than polyadenylation, with many of the affected genes implicated in several neuronal functions and neuropsychiatric disorders.

Sox2 suppresses gastric tumorigenesis in mice [RNA-seq]

Project description:Purpose: Sox2 expression marks gastric stem and progenitor cells, raising important questions regarding the genes regulated by Sox2 and the role of Sox2 itself during stomach homeostasis and disease. The goal of this study is to determine the function of and the genes regulated by Sox2 in the stomach. Methods: mRNA profiles of Sox2 WT and Sox2 KO gastric glands were generated by RNA-sequencing, in triplicate, using a Illumina HiSeq 2500 instrument, resulting in 36 million single-end 50bp reads per smaple. Sequencing reads were mapped to the mouse reference genome (mm10/GRCm38) using STAR (Dobin et al., 2013). Read counts over transcripts were calculated using HTSeq v.0.6.0 (Anders et al., 2015) based on a current Ensembl annotation file for mm10/GRCm38 (release 75). Results: Sox2 is dispensiable for gastric stem cell self-renewal and epithelial homeostasis, however modulates the expression of cancer and intestinal related genes. mRNA profiles of stomachs from 10 week old Sox2 WT and Sox2 KO mice were generated by sequencing, in triplicate, using a Illumina HiSeq 2500.
