The invention provides compositions and methods for reducing one or more symptoms of disease by administering compositions comprising SipA. The invention's compositions and methods are particularly advantageous in reducing symptoms of diseases that are associated with overexpression of P-gp and/or p53. The invention's compositions and methods are useful in reducing cancer symptom and/or cancer multidrug resistance (MDR). The invention provides a method for reducing one or more symptoms of cancer in a mammalian subject in need thereof, comprising administering to said subject a composition comprising purified SipA. In one embodiment, said SipA is operably conjugated to a nanoparticle. In another embodiment, said cancer comprises cancer cells resistant to at least one cytotoxin.
该发明提供了通过给予含有SipA的组合物来减轻疾病的一个或多个症状的组合物和方法。该发明的组合物和方法在减轻与P-gp和/或p53过表达相关的疾病症状方面特别有优势。该发明的组合物和方法在减轻癌症症状和/或癌症多药耐药性(MDR)方面非常有用。该发明提供了一种用于减轻哺乳动物受试者中的一个或多个癌症症状的方法,包括向所述受试者给予包含纯化SipA的组合物。在一个实施例中,所述SipA与纳米颗粒可操作地结合。在另一个实施例中,所述癌症包括对至少一种细胞毒素具有抗性的癌细胞。
