Example sentences for: paclitaxel
How can you use “paclitaxel” in a sentence? Here are some example sentences to help you improve your vocabulary:
This 55-y-old female “never smoker” was treated for nearly 4.5 y with weekly paclitaxel and trastuzumab [17] for adenocarcinoma with bronchioloalveolar carcinoma features involving her left lower lobe, pleura, and mediastinal lymph nodes.
Over the past decade paclitaxel and docetaxel have become important chemotherapeutic agents for both ovarian and breast cancers [ 1 2 ] . Considerable interest has focused on the target receptor - tubulin - and mechanisms underlying efficacy, toxicity, and drug resistance [ 7 8 23 24 27 28 ] . Whether tubulin isotype levels might determine cellular responses to antimitotic agents remains controversial.
For example, total amounts of polymerizable tubulin are decreased in paclitaxel-resistant cells, whereas col-cemid-resistant tubulin or vinca alkaloid-resistant cells have increased levels of assembled tubulin [ 34 66 67 ] . Furthermore, when cells were transfected with β-tubulin class III, weak resistance to paclitaxel was found, and this resistance was associated with decreased microtubule stability [ 68 ] . This is consistent with the different modes of action of these drugs: paclitaxel stabilizes microtubules and colcemid inhibits tubulin assembly.
Furthermore, transfection of CHO cells with β-tubulin classes I, II, or IVb did not produce resistance to paclitaxel [ 32 ] . The alternative hypothesis, derived from the work of Cabral and colleagues, is that rather than the tubulin isotype levels, the amount of polymerized tubulin is the critical factor that regulates response to antimitotic drugs.
Furthermore, whereas some of these data suggest a role for tubulin isotypes in drug resistance, cell growth, and differentiation, other work indicates that isotype-independent factors affecting micro-tubule polymer formation are more important than changes in isotype levels [ 32 33 34 35 ] . For example, a decrease in total polymer concentrations causes resistance to microtubule-stabilizing agents such as paclitaxel [ 34 35 ] .
