Paclitaxel Resistant and Dependent Cell Lines

Description:

The Technology: Dr. Fernando Cabral at the University of Texas Health Science Center at Houston (UTHealth) has developed a series of mutant cell lines with altered sensitivity to antimitotic drugs. Paclitaxel is a drug that binds to polymerized tubulin and inhibits microtubule disassembly. One of the major limitations in using these drugs, however, is the emergence of drug resistant tumor cells. The inventor has found that some tubulin isotypes alter sensitivity to antimitotic drugs by perturbing microtubule assembly, while others have little effect on assembly but increase the binding of specific drugs.
