| Outline of Final Research Achievements |
Synthetic transcriptional activators adept of therapeutic gene modulation could be harnessed for developing strategies to treat some uncured defect-transcriptional machinery associated disorders. We have successfully advanced distinct DNA-based epigenome-modulating small molecules as first-ever bio-inspired genetic switches for activating exclusive cluster of therapeutically important genes including those providing resistance towards ocular disorders and HIV. Also, an `ON` switch for miR-302 familial microRNAs and an `OFF` switch for EVI1 oncogene were developed. Integration of epigenetic modulators on synthetic DNA-based domain effectively activated genes associated pluripotency and cartilage development. Next-generation sequencing studies guided the construction of second-generation genetic switches. Our proof-of-concept studies validate the switchable roles of epigenetic enzymes in gene regulation and provide a molecular basis for developing versatile bioactive ligands.
