To confirm that RCBTB1 expression level could impact response to docetaxel, we analyzed the effect of RCBTB1 downregulation in a dedifferentiated liposarcoma cell line (LPS80), which is not deleted for RCBTB1 and expresses the most RCBTB1 among our sarcoma cell lines, according to Taqman experiments. This evidence concerns the gene RCBTB1 and sarcoma.
