Title MAPT expression is mediated by long-range interactions with cis-regulatory elements [RNA_timecourse]
Organism Homo sapiens
Experiment type Expression profiling by high throughput sequencing
Summary Tau is encoded by MAPT and abnormal aggregates of tau are a hallmark of a group of neurodegenerative diseases called tauopathies. MAPT is lowly expressed in neural progenitor cells (NPCs), but it is more highly expressed in oligodendrocytes, astrocytes, and neurons that derive from NPCs. This expression switch at differentiation suggests that MAPT expression is controlled by transcription factors and cis-regulatory elements specific to these differentiated cell types, including neurons.
Overall design We performed HiC and three-dimensional chromatin conformation capture (Capture-C), single-nucleus multiomics (RNA-seq and ATAC-seq), bulk ATAC-seq, and ChIP-seq for H3K27Ac and CTCF in neurons differentiated from human iPSC cultures. From these methods, we nominated candidate cis-regulatory elements (cCREs) for MAPT in human NPCs, NPCs differentiated to neurons, and pure inhibitory or excitatory neuron cultures. We then functionally assessed nominated regions using luciferase assays and CRISPR dCas9-KRAB inhibition experiments to assess the effect of nominated regions on MAPT expression.
