Abstract

Alternative polyadenylation (APA) in 3’ untranslated region (3UTR) is a post- transcriptional modification mechanism, which is shown to play important roles in the development of Schizophrenia. However, current studies mainly study APA in Schizophrenia on the bulk RNA-seq level. This thesis aim to chart APA events in different cell types from a previously published scRNA-seq dataset, which is generated from organdies derived from Schizophrenia patients. The analysis is based on a published method called SCAPE. Our results illustrate that 3UTR of APA genes tend to be shorter in the Schizophrenia group compared with the control. Through various analysis, we identified several marker genes that exhibit differential APA isoform usage between Schizophrenia and control, including TGFB1, SHANK2, GRB2, THOC3, NDUFAF4, FLVCR1-DT, OXAND1, SAP30L, HSBP1, ELP5. Many of these genes have been reported to be associated with Nervous System Diseases and Mental Disorders, which worth further investigation.
