Key Discoveries & Contributions by Mariano Barbacid
1.Isolation of the first human oncogene (HRAS) — In 1982, Barbacid’s group was one of the three labs that isolated HRAS from a human bladder carcinoma, marking the first human oncogene identified and linked to cancer.
2.Identification of the first cancer-associated mutation — He helped identify a specific point mutation in HRAS that was responsible for its oncogenic (cancer-causing) properties.
3.Isolation of the TRK oncogene — In the early 1990s, Barbacid’s research isolated the TRK gene from colon carcinoma, which became a foundation for targeting nerve-growth-factor pathways and tumor-agnostic therapies.
4.Discovery of TRK family receptors for neurotrophins — His work led to recognizing TRK tyrosine kinase receptors as functional receptors for the NGF family of neurotrophic factors, important in both neuroscience and oncology.
5.Advancement in targeted cancer drug strategies — At Bristol-Myers-Squibb, he helped pioneer oncology drug discovery focusing on molecular targets in cancer.
6.Redefined role of CDKs in the cell cycle — His group showed that some cyclin-dependent kinases (CDKs) previously thought essential for cell division (e.g., CDK2) were actually dispensable for DNA replication, reshaping understanding of cell cycle regulation.
7.Leadership in cancer research institution building — Founded and directed the Spanish National Cancer Research Centre (CNIO) in Madrid, establishing it as a major global oncology research hub.
8.Recent therapeutic animal studies — His lab has pioneered combined target strategies (e.g., targeting KRAS, EGFR, STAT3, RAF1) in genetically engineered mouse models to regress pancreatic and lung tumors, advancing translational cancer therapy research.
