Chromosomal Rearrangements Associated with Chemotherapeutic Drug Resistance

By Kevin E. Noonan — Chemotherapeutic drug resistance is one reason cancer remains an unsolved clinical problem despite the efforts ever since President Nixon declared his “War on Cancer” in 1971. Cancer cells, due in part to the genetic destabilization characteristic of the disease, are capable of expressing genes (normal or aberrant) that permit the cell to avoid the cytotoxic effect of such drugs with the patient providing the situs of selection for and growth of resistant cells. The phenomenon is certain tumor types can have more deleterious consequences than in others, and this is particularly true for glioblastomas (and…
