Abstract
A dataset of single-nucleus RNA sequencing (snRNAseq) data was analyzed using Seurat, Sierra, and Ingenuity Pathway Analysis (IPA) programs to assess differentially expressed genes (DEGs) and differential transcript usage (DTU) in mouse hippocampal cell types. Seurat identified DEGs between the wild type (WT) and Apoe knockout (EKO) mice. IPA identified 11 statistically significant canonical pathways in >1 cell type. Sierra identified Sipa1l1 with DTU between WT and EKO samples. Analysis of the Sipa1l1 peak region identified an alternative non-canonical polyadenylation signal and a putative cytoplasmic polyadenylation element. APOE regulation of gene transcription and co-transcriptional RNA processing may underlie Alzheimer's disease.
