P-glycoprotein ABCB1 plays a major role in MDR of malignant cells and is regulated by various transcription factors, including Wnt/¦Â-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 %K ABCB1 %K Wnt/¦Â-catenin signaling %K 15-oxospiramilactone %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4842754/
