Epigenetic regulation of neuropsychiatric disorders.
Brain function requires accurate control of gene transcription in response to environmental stimuli. Epigenetics plays a core role during this process by modulating gene expression without changing underlying DNA sequences. It has therefore been implicated in various neuropsychiatric disorders. With help of modern genomic tools and novel epigenetic concepts largely developed in proliferating cultured cells, I aim to decipher out the epigenetic underpinnings of neuropsychiatric diseases in vivo by using rodent models.
In the past, my studies revealed several modes of epigenetic regulation of cocaine action and depression in mouse nucleus accumbens (NAc), a key brain reward region. 1) we found unique combinations of histone modification changes/signatures, which accompany cocaine’s regulation of gene expression. Importantly, they have a widespread correlation with pre-mRNA alternative splicing (by RNAseq). Based on this, we further identified a novel role of splicing factor A2BP1 in cocaine behavioral abnormalities. 2) TET oxidases were recently recognized to mediate the conversion of methylated DNA to 5-hydroxymethylcytosine (5hmC). This not only presents additional layers of DNA epigenetic modification, but also provides a long sought after DNA demethylation pathway. We found repeated cocaine administration selectively decreases TET1 in NAc, which enhances behavioral responses to cocaine. Furthermore, we also demonstrated associated 5hmC dynamics in both coding regions and putative enhancer areas. 3) We showed that β-catenin mediates pro-resilient effects after social defeat stress. Through genome-wide β-catenin enrichment mapping (ChIP-seq), we recognized Dicer1, important in microRNA biogenesis, as a novel β-catenin target. And Dicer1 mediated β-catenin-dependent microRNA regulation is associated with this stress resilience.
In my independent lab at FSU where I started in the summer of 2015, I look forward to continuing my neuroepigenetic efforts to study more biologically significant questions across a broader range of neuropsychiatric disorders with a focus on DNA epigenetics and non-coding RNAs. The laboratory will emphasize an integration of cutting-edge epigenetic/genomic tools with behavioral neuroscience researches. Highly motivated individuals are encouraged to apply to a position at all levels (e.g. undergrad researcher, graduate student, technician, and postdoc fellow) at anytime. I hope to work with you to explore novel epigenetic underpinnings of neuropsychiatric disorders derived from findings in aforementioned researches and beyond.
