Spatial Memory
How do specific RNA modification pathways drive the formation and stability of cell maps underlying spatial memory? How is accuracy of spatial representation achieved?
The RNA Modifications, Intellect, and NeuroDegeneration (RNA-MIND) Lab at New York University Abu Dhabi aims to delineate the molecular mechanisms involving dynamic RNA modifications and their function in synaptic, neuronal, and behavioral plasticity. RNA modifications, including more than 50 found in human cells and 120 in microbes and pathogens, hold vast potential to overwrite and redefine life sciences and medicine by coding for cellular functions with unprecedented complexity. The dynamic and responsive nature renders this regulatory pathway well poised to support the highly adaptive functions of our brain cells, such as forming cellular engrams of learning. Nonetheless, the mechanisms connecting RNA regulation and cognitive function remain largely obscure.
At the RNA-MIND lab, we use cutting-edge detection and intervention technologies to chart unknown connections between RNA-based regulation of cellular function and cognitive functions of the brain. Genetically engineered mice and human cells are studied using a combination of highly sensitive techniques ranging from bioinformatics, biochemical assays, cell culture, in vivo neuronal activity recording, cellular fluorescence imaging, next-generation sequencing, to automated behavioral analysis, to advance our understanding of how individuals’ brains are wired through the lens of RNA regulation. We believe that our findings will contribute to the acceleration of a new generation of RNA therapies to combat neurological and mental health disorders such as Alzheimer’s.
Critical questions are addressed in key areas: health-related neurological dysfunctions and the development of new technology.
How do specific RNA modification pathways drive the formation and stability of cell maps underlying spatial memory? How is accuracy of spatial representation achieved?
Does the epitranscriptome serve as a dynamic interface between experience and brain plasticity? What role does it play to influence the interaction between genes and environement? And how?
How is epitranscriptomics connected to the protein composition at subcellular locations? What factors influence this process to achieve plasticity in gene expression? Does epitranscriptomic regulation collaborate with epigenetics in fine-tuning gene expression?
What mutations/genetic variations exist in the human genome that affect our cognition by impacting RNA modification and regulation? Do we synthesize our entire RNA coding repertoire or rely on external sources such as microbiota?
How does dynamic RNA modification assist immune responses and neuronal integrity in multiple sclerosis, ALS, or other neurodegenerative diseases?
What aspect of RNA regulation is influenced by modification? Splicing, stability, localization, translatability, and/or coding?
