Transcription profiling of murine olfactory epithelium during neuronal death and replacement to study adult neurogenesis in the olfactory epithelium

Project description:Expression profiling of mRNA abundance in the adult mouse olfactory epithelium during replacement of OSNs forced by the bilateral ablation of the olfactory bulbs. The experiment was done on 6 week old male C57Bl/6 mice. Olfactory epithelium tissue samples were collected on days 1, 5, and 7 after bulbectomy. The cellular processes activated by bulbectomy include apoptosis of mature olfactory sensory neurons, infiltration of macrophages and dendritic cells, stimulation of proliferation of basal cell progenitors, and differentation of new sensory neurons.

RNA sequencing analysis of unilateral orchidectomy, bilateral orchidectomy, and Nell2 knockout initial segment-caput epididymis.

Project description:Purpose: The purpose of this study is to characterize genes whose expressions in the initial segment (IS)-caput epididymis were affected by unilateral orchidectomy (UOD), bilateral orchidectomy (BOD), and Nell2 gene ablation. Methods: The unilateral or bilateral orchidectomy of WT mice was performed from 8 weeks old and continued for 4 weeks until tissue sampling at 12 weeks old. Contralateral epididymis was used as a control for UOD. Sham operation was also done as a control for BOD. Nell2-/- mice and their control WT mice were used wthen they were 14-week-old. IS-caput epididymal mRNA profiles were generated by deep sequencing, in triplicate, using Illumina NovaSeq6000. Results: RNA-seq data identified differentially expressed transcripts. Conclusions: Our results show that the expression of many genes was affected by UOD, BOD, and Nell2 ablation.

Transcriptional profiling of basilar artery and basilar terminus intima and media in rabbits after bilateral carotid ligation

Project description:New Zealand white rabbits underwent bilateral carotid ligation to increase flow in the basilar artery (BA) or sham surgery. 24 hours post-surgery, the BA and basilar terminus (BT) were embedded for sectioning. The intima and media were separately laser-microdissected from the sections, and whole transcriptome RNA-seq was performed on each tissue in order to more thoroughly characterize potential molecular signals between endothelium and smooth muscle during flow-induced arterial remodeling.

Expression data from RH30 vector and RH30 IκBα SR cells

Project description:Classical NF-κB activity can be inhibited by overexpression of the IκBα super repressor (SR). To determine the role of NF-κB in rhabdomyosarcoma cells, we overexpressed the IκBα SR in RH30 rhabdomyosarcoma cells. IκBα SR was overexpressed in RH30 cells. RH30 vector cells were used as control group.

Genome-wide Analysis Reveals SR Protein Cooperation and Competition in Regulated Splicing

Project description:SR proteins are well-characterized RNA binding proteins that promote exon inclusion by binding to exonic splicing enhancers (ESEs). However, it has been unclear whether regulatory rules deduced on model genes apply generally to activities of SR proteins in the cell. Here, we report global analyses of two prototypical SR proteins SRSF1 (SF2/ASF) and SRSF2 (SC35) using splicing-sensitive arrays and CLIP-seq on mouse embryo fibroblasts (MEFs). Unexpectedly, we find that these SR proteins promote both inclusion and skipping of exons in vivo, but their binding patterns do not explain such opposite responses. Further analyses reveal that loss of one SR protein is accompanied by coordinated loss or compensatory gain in the interaction of other SR proteins at the affected exons. Therefore, specific effects on regulated splicing by one SR protein actually depend on a complex set of relationships with multiple other SR proteins in mammalian genomes.

iCLIP seq reveals distribution of genome-wide SR protein-RNA binding

Project description:We identified the precise genome-wide binding sites for all SR proteins, using iCLIP-seq SR proteins were encoded on stable transgenes, transfected in S2 cells, FLAG-tag immunopurified, and the bound RNA purified and subjected to RNA-seq. The resulting reads (CLIP tags) were aligned to the Drosophila genome and generated 38,695-5,900,000 unique CLIP tags for each SR-protein replicate.

Transcriptomic profiling of E9.5 mouse embryos lacking the lipoprotein receptor SR-B1

Project description:The high-density lipoprotein receptor SR-B1 mediates cellular uptake of several lipid species, including cholesterol and vitamin E. During early development, SR-B1 is located in the maternal-fetal interface, where it facilitates vitamin E transport towards the embryo. Consequently, embryos lacking SR-B1 are vitamin E-deficient, and around half of them fail to close the neural tube and show neural tube defects (NTD). Here, we studied the transcriptomic profile of mouse embryos lacking SR-B1 to identify the molecular determinants of this phenotypic difference. We used RNA-Seq to analyze the expression of mRNA globally in E9.5 wild-type embryos and embryos lacking SR-B1 with or without NTD, in order to compare expression profiles in those groups and to identify putative genes driving phenotypic differences.
