PML/RARA destabilization by hyperthermia: a new model for oncogenic fusion protein degradation?

In this issue, Maimaitiyiming and colleagues demonstrate thermic stress-induced PML/RARA oncogenic fusion protein destabilization driven by corepressor aggregation. Hyperthermia synergizes with PML/RARA degradation by ATO and may circumvent ATO-resistance in historical APL patients. This novel approach could be extended to other corepressor-associated oncogenic fusion proteins.
