Project description:A large number of computational methods have been recently developed for analyzing differential gene expression (DE) in RNA-seq data. We report on a comprehensive evaluation of the commonly used DE methods using the SEQC benchmark data set and data from ENCODE project. We evaluated a number of key features including: normalization, accuracy of DE detection and DE analysis when one condition has no detectable expression. We found significant differences among the methods. Furthermore, computational methods designed for DE detection from expression array data perform comparably to methods customized for RNA-seq. Most importantly, our results demonstrate that increasing the number of replicate samples significantly improves detection power over increased sequencing depth.
Project description:We generated Multiome RNA+ATAC data from the same cell from human PBMC. This served as a gold benchmark for a novel integration method for multi-omics data that we developed.

Project description:To compare the effects of RXR inhibition to APC depletion on chromatin landscapes, WT organoids were treated with either HX531 (RXRi) or vehicle (WT). APCko tumorids treated with vehicle only were used as a benchmark. We then performed differential accessibility analysis using data obtained from ATAC-seq of the indicated organoid lines.
