GSE138695: Gene expression analysis of astrocytes differentiated from iPS cells generated from the fibroblasts of PSEN1deltaE9 mutant AD and their isogenic control iPS lines

Bulk RNA sequencing

Mutations in presenilin 1 (PSEN1) cause a familiar form of Alzheimer's disease (AD). We have obtained skin biopsies from two individuals carrying PSEN1 exon9 deletion and reprogrammed skin fibroblasts into induced pluripotent stem cells (iPSCs). To get controls, we have corrected PSEN1 exon9 deletion by CRISPR/Cas9 technique. Since astrocytes play role in AD pathogenesis, we further differentiated iPSCs into astrocytes. We ran RNA sequencing analysis to compare our iPSC-derived astrocytes with previously published data on human astrocytes and to identify genes and pathways affected by PSEN1 exon 9 deletion.
