In a stunning discovery, researchers at the University of Pennsylvania have harnessed a deadly fungus, once blamed for the “Pharaoh’s Curse,” to develop a promising new treatment for blood cancer.
This breakthrough, rooted in a toxin produced by the Aspergillus flavus mold, could offer hope to patients battling leukemia.
The story begins in the 1920s, when famed archaeologist Howard Carter opened King Tutankhamun’s tomb, an event followed by the mysterious deaths of eight team members. Whispers of a “Pharaoh’s Curse” spread, but medical experts suspected a fungal culprit.
Decades later, the excavation of King Casimir IV of Poland’s tomb in the 1970s confirmed these suspicions. Four of twelve archaeologists died within weeks, and investigators pinpointed Aspergillus flavus, a highly toxic fungus, as the cause. This mold produces asperigimycin, a toxin lethal to lung tissue but now showing remarkable potential in cancer research.
The University of Pennsylvania team discovered that asperigimycin is exceptionally effective at destroying leukemia cells in lab tests. However, the toxin required modification to become a viable cancer therapy.
Using a cutting-edge technique known as ribosomally synthesized and post-translationally modified peptides (RiPPs), the researchers engineered asperigimycin peptides.
