Cells with variable beta-tubulin composition

Description:

Cells with Variable Beta-tubulin Composition

The Technology: A faculty member of the University of Texas Health Science Center at Houston has developed a set of cell lines, each of which overexpresses a different isotype of β-tubulin. More specifically, the cell lines overexpress β-tubulin I, II, III, IVa, IVb, V or VI. The cell lines are thoroughly characterized and have been used in studies investigating microtubule assembly and cellular resistance to antimitotic drugs such as paclitaxel and vinblastine. 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.
