Gleevec (Imatinib): The Chromosome that Named its Own Drug
In the early 1970s, researchers studying bone marrow and blood samples from chronic myeloid leukemia (CML) patients noticed something strange under the microscope…an abnormally short chromosome 22. It was named, “The Philadelphia chromosome,” after the city where it was discovered by David Hunderford (a graduate student/research fellow) and Peter Nowell (a pathologist), who identified the…
Herceptin (Trastuzumab): The Gene that Turned a Death Sentence into a Treatable Disease
In the 1980s, breast cancer treatment was largely a one-size-fits-all approach. And then, researchers studying tumor tissue biopsies noticed something unusual: in roughly 1 in 5 patients, tumor cells had far too many copies of a gene called HER2/neu. This wasn’t a minor detail. Patients with HER2-amplified tumors, identified through paraffin-embedded and frozen tissue samples,…
