Areas of Research: We study single mRNA molecules in single cells using high resolution imaging techniques. We develop microscopy technology using fluorescent-labeled probes to visualize and quantify mRNAs within the cell and tissue.

Professional Interests

Dr. Eliscovich focuses her research towards to the elucidation of RNA regulatory mechanisms facilitated by RNA-binding proteins during development and disease. She is interested in develop imaging methods to study gene expression regulation in living cells and tissue. She has developed a robust methodology, named ‘super registration’, using single-molecule RNA Fluorescence in situ hybridization in combination with immunofluorescence (smFISH-IF) to determine the physical interaction between individual mRNA molecules and their binding proteins in single cells using standard wide-field microscopy. This imaging method extends biochemical-based studies on RNA-protein interactions by providing spatial information about where in the cells these interactions are likely to occur. This is especially important in neurons, in which RNA regulatory mechanisms play an essential role in the regulation of localized gene expression. Super registration represents a solution to the historical problem of colocalization of two colors using optical microscopy. The secret to the success was devising a method to correct the intrinsic aberration of the commercial microscope objectives, each of which is unique. This allows her the use of fluorescence imaging to characterize the interaction of two molecules while in their native environment.

She is also interested in explore heterogeneity in gene expression in the liver as a tissue model. Virtually nothing is known about how an mRNA is regulated in primary cells or in their native context in the tissue. By characterizing molecular events as they occur in intact tissue, Dr. Eliscovich uses modern imaging technology to examine cause-and-effect relationships and quantitative kinetics to build predictive models of gene expression. Application of single-molecule and single-cell analyses to histopathology promises to yield new insights into the pathobiology of liver disease.
