Project description:we present a novel path to drug repurposing to identify new immunotherapies for ASCVD. The integration of time of-flight mass cytometry (CyTOF) and RNA-sequencing identified unique inflammatory signatures in peripheral blood mononuclear cells (PBMCs) stimulated with ASCVD plasma. By comparing these inflammatory signatures to large-scale gene expression data from the LINCS L1000 dataset, we identified drugs that could reverse this inflammatory response. In conclusion, a systems immunology-driven drug repurposing with pre- clinical validation strategy can aid the development of new cardiovascular immunotherapies.

Project description:Small regulatory RNAs including small interfering RNAs (siRNAs) and microRNAs (miRNAs) guide Argonaute (Ago) proteins to specific target RNAs leading to mRNA destabilization or translational repression. We recently reported the identification of Importin 8 (Imp8) as a novel component of miRNA-guided regulatory pathways. Imp8 interacts with Ago proteins and localizes to cytoplasmic processing bodies (P-bodies), structures involved in RNA metabolism. For this micro-array dataset, we used immunoprecipitations of Ago2-associated mRNAs followed by micro-array analysis. The results demonstrate that Imp8 is required for recruiting Ago protein complexes to a large set of Ago2-associated target mRNAs allowing for efficient and specific gene silencing. Therefore, we provide evidence that Imp8 is required for cytoplasmic miRNA-guided gene silencing.
Project description:Histone modification H3K9me2 is associated with gene silencing and forming large heterochromatin domains. But the micro-structure within large H3K9me2 domains and their relationship with DNA methylation remains unclear. This dataset was generated to compare with genome-wide DNA methylation data.
Project description:In this study, we compare the performance of RNA-seq (Illumina HiSeq) and junction arrays (Affymetrix Human Transcriptome array) for the analysis of splicing events. Three different cell lines were treated with CX-4945, a drug that severely affects splicing. To make a fair comparison, we developed EventPointer, an algorithm that detects and labels alternative splicing events in both junction arrays and RNA-seq. Common results and discrepancies between both technologies were validated or resolved by more than 200 PCRs.
