NEUROCROM – Phase III (2020-2023)
SUMMARY
The research teams at the Institute of Neuroscience led by Drs. Eloisa Herrera, Ángel Barco, and José López-Atalaya, continue their collaborative efforts to address, in a coordinated manner, the investigation of TRANSCRIPTIONAL AND EPIGENETIC DYSREGULATION IN NEURODEVELOPMENTAL DISORDERS.
The assembly of neuronal circuits is heavily dependent on the actions of transcription factors and epigenetic regulators. In fact, a significant number of genetic disorders affecting nervous system development stem from mutations in genes encoding these types of proteins. The sequence of events during development that require gene expression regulation includes cell migration, dendritic and axonal specification, neurite growth, axonal guidance, synapse formation with target cells, and circuit remodeling through experience and learning. These processes largely depend on precise interactions over time and space between different types of neurons and between neurons and glial cells. Dysregulation of the processes governing the assembly of neuronal circuits during development dramatically impacts circuit connectivity and can lead to embryo resorption, premature death, or varying degrees of neuropsychiatric disorders depending on the extent of dysregulation.
The NEUROCROM group is a leader in researching the molecular etiology of such disorders. We have recently pioneered the analysis of the nuclear transcriptome of individual neurons (single nucleus RNA-seq) and changes in chromatin accessibility and occupancy by transcription factors (ATAC-seq) in both neurons and microglia. Within the framework of this project, we propose to continue our investigation into the dysregulation of gene programs underlying various genetically relevant clinical disorders arising from deficiencies in transcription factors and enzymes that modify chromatin. We anticipate that the results obtained in this project will contribute to: (i) elucidating the role of transcriptional and epigenetic mechanisms in the development of the mammalian nervous system; (ii) providing new insights into the molecular etiology of developmental nervous system diseases caused by mutations in transcription factors and epigenetic regulators; and (iii) identifying and evaluating new targets and therapeutic strategies for these disorders. To achieve this, we plan to continue innovating in the application of genomic analysis techniques to address the issue of cellular differentiation and plasticity during the formation of neuronal circuits.
