Pier Paolo Pandolfi

Pier Paolo Pandolfi proposed the competing endogenous RNA (ceRNA) hypothesis, a paradigm-shifting concept that lncRNAs, pseudogenes, and mRNAs communicate by competing for shared microRNAs, fundamentally altering understanding of gene regulation in cancer. His discovery that the PTEN pseudogene PTENP1 functions as a ceRNA to protect PTEN mRNA from miRNA-mediated degradation provided the first experimental evidence for this regulatory network. He has demonstrated how ceRNA network disruption contributes to tumorigenesis. His ceRNA framework has generated a new dimension of cancer biology research.
