Use Case 2: HDL-bound small RNA in Lupus 1 Data and background slides kindly provided by Kasey Vickers, Vanderbilt University. Use Case 2: High-Density Lipoproteins – small RNA Signatures in Systemic Erythematosus Lupus Organized and Hosted by the Data Management and Resource Repository (DMRR) Wednesday, Nov 5 th, :00 – 8:30 pm
Use Case 2: HDL-bound small RNA in Lupus million Americans Systemic Inflammation Increased production of autoantibodies against multiple antigens: dsDNA, histones, HDL, apolipoproteins, phospholipids, RBC Background: Systemic Lupus Erythematosus (SLE) 9 out of 10 SLE patients are women Presents between ages 20-40, with 15-20% of cases presenting before 18 years of age Increased frequency in African American and Hispanic women
We sought to ask if HDL-small RNAs contribute to SLE- accelerated atherosclerosis. Thus, this use case focuses on non-vesicular exRNA, whereas most exRNA work to date has focused on vesicular exRNAs. We therefore wish to use the short-RNA Seq pipeline in the Genboree Workbench to ask if HDL-small RNAs are altered in SLE subjects. Results: We found that 0.25% of reads isolated from HDL particles map to miRNAs, which is lower than other strategies that resulted in 1.63%, 3.2%, and 1.8% mapped miRNAs. 3 Use Case 2: HDL-bound small RNA in Lupus
