Penn develops fPE7max for anticancer drugs

Researchers led by Xue Gao at the University of Pennsylvania have developed a novel genome-editing tool called fPE7max, specifically designed for filamentous fungi. This tool allows for precise manipulation of fungal genomes, overcoming limitations of previous technologies like CRISPR. Using fPE7max, the team successfully activated silent gene clusters in various fungal species, leading to the discovery of 18 distinct complex molecules. Of these, eight possessed entirely new chemical structures, and three exhibited promising anticancer properties against human breast, hepatic, and leukemia cancer cells. This research, published in Sana Biotechnology, opens a new avenue for drug discovery by systematically optimizing the search for natural products from fungi, moving away from traditional treasure-hunt approaches.
