HDDC3 and fibrosarcoma: We expanded this finding in a broader panel of cancer cell lines, including renal cell carcinoma (RCC4, 786-O), breast cancer (BT20, BT474, MCF-7), chondrosarcoma (SW-1353), and fibrosarcoma (HT-1080), and noticed a consistent cell number reduction by MESH1 knockdown (Supplementary Fig. 1d).
