“Life Through Colors: Single-cell fluorescence-based reporter system for monitoring gene expression”

The presentation will depict a long journey from decision to actual making a novel reporter system for RNA silencing, which could also be adopted for studying other mechanisms manipulating gene expression. This development lead to production of two types of triple-color reporter HeLa lines where fluorescence reporters are inserted in frame in into endogenous genes encoding highly abundant soluble nuclear proteins. The system now allows for monitoring repression (loss of specific dluorescence) and derepression (appearence of previously silenced fluorescence) across the entire population of cultured cells and, possibly, for high throughput screening.
