| 摘要 |
The present invention provides methods and compositions for regulating rapamycin resistance and/or tumorgenesis by modulating the expression and/or the activity of annexin XIII gene. The invention also provides methods and compositions for treatment of diseases, e.g., cancers, by modulating the expression and/or activity of annexin XIII gene. The invention also provides methods and compositions for diagnosing and screening annexin XIII mediated rapamycin resistance and/or tumorgenesis in patients. The invention further provides host cells whose annexin XIII gene can be reversibly switched on or off, and to methods of using annexin XIII gene in evaluation and screening for drugs which regulate rapamycin resistance and/or tumorgenesis. The invention also provides methods for generating genetically modified cells having altered sensitivity to rapamycin by knocking out a gene which mediates rapamycin resistance.
