Caveolae and multidrug resistance of tumor cells / 肿瘤研究与临床

ABSTRACT

Caveolae is a specified micro-domain of plasma membrane, which consists of caveolin and many lipid molecules and membrane proteins. Caveolae plays important roles in internalization of extra-membrane molecules, transmembrane signal transdution and transport of cholesterin. Recent studies indicated that caveolae and its components were up-regulated in multidrug resistant tumor cells and might participate the development of multidrug resistance of tumor cells. This paper concentrated on the role of caveolae in tumor multidrug resistance.
