    摘要: Chemotherapeutic agents that interfere with microtubule assembly or disassembly in the cell are potent inhibitors of cell replication. Examples of such agents include halichondrin B analogs. It has been shown that the susceptibility of certain cancers to analogs of halichondrin B correlates with the expression of particular tubulin isotypes or other microtubule-associated proteins such as MAP-4 and stathmin. Correlations such as these may be used in identifying patients suitable for treatment using a particular chemotherapeutic agent. Such a system avoids treating patients with cytotoxic compounds where there is a minimal or no effect on the cancer. The invention also provides a system of establishing these correlations for different compounds and cancer types. The system will be particularly useful in establishing correlations between anti-microtubule agents and cancers such as lung, breast, and ovarian cancer. Kits and reagents useful in practicing the invention are also provided.
