Research Abstract

Artificial transcriptional activators with epigenetic activity can retain the capability of their natural equivalents to rewire transcriptional machinery within a cell. During this tenure, we have demonstrated the potential of our novel small molecules for genome engineering termed `SAHA-PIP` containing sequence-specific pyrrole-imidazole polyamides (PIPs) and SAHA, a histone deacetylase inhibitor. We tailored SAHA-PIPs to distinctively activate the pluripotency genes by triggering transcriptionally permissive chromatin in mouse fibroblasts. We have generated PIP conjugates with fluorescent dyes and those targeting different epigenetic enzymes. In human fibroblasts, a SAHA-PIP got characterized as germ cell gene switch and genome-wide gene analysis revealed the capability of thirty-two distinct small molecules to trigger the transcriptional activation of exclusive developmental genes. Our results contribute to the development of novel chemical approach for controlling cell fate.
