Cell type-specific mechanism of Setd1a heterozygosity in schizophrenia pathogenesis [CUT&RUN]

Project description:Schizophrenia (SCZ) is a chronic, serious mental disorder with severe burden on patients’ families and society. Although over 100 genes have been linked to SCZ pathogenies, the underlying molecular and cellular mechanisms remain largely unknown. Here, we generated a Setd1a haploinsufficiency mouse model to understand how this SCZ-associated epigenetic factor affects gene expression programs in cells of brain regions highly relevant to SCZ. By comparing single-cell RNA-seq results from wild type and Setd1a+/- mice, we found Setd1a heterozygosity causes highly diverse transcriptional adaptations across different cell types in prefrontal cortex and striatum, suggesting brain region- and cell type-specific mechanisms contribute to pathophysiology of SCZ. Interestingly, we found the Foxp2+ neurons exhibit the most prominent gene expression changes among the different neuron subtypes in PFC, which correlate with the H3K4me3 changes. Importantly, many of the genes dysregulated in heterozygous Setd1a mice are linked to neuron morphogenesis and synaptic function. Consistently, heterozygous Setd1a mice exhibit certain behavioral features of SCZ patients. Collectively, our study establishes Setd1a heterozygous mice as a model for understanding SCZ and uncovers a complex brain region- and cell type-specific changes that potentially underlying SCZ pathogenesis.
