RCBTB1 and liposarcoma: 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.
