AB249. 15-oxospiramilactone reverses multidrug resistance in the Human Renal Cell Carcinoma by targeting ABCB1 through Inhibition of Wnt/β-catenin signalingKeywords: ABCB1, Wnt/β-catenin signaling, 15-oxospiramilactone Abstract: Multidrug resistance (MDR) is the main barrier to the success of chemotherapy for Human Renal Cell Carcinoma. P-glycoprotein ABCB1 plays a major role in MDR of malignant cells and is regulated by various transcription factors, including Wnt/β-catenin /TCF4. We previously reported 15-oxospiramilactone was a new Wnt molecule inhibiter. In this study, ABCB1 was found to be significantly down regulated in A498 and ACHN cells by using 15-oxospiramilactone, suggesting an important role for the Wnt/b-catenin/TCF4 signaling pathway in cancer drug resistance
