CHMP4B and liposarcoma: The NRGs expression within HSF, SW-982, hSS-005R, and SW-872 cell lines were quantified by RT-qPCR in order to verify the expression level of some key NRGs. As shown in Figures 3A–C, compared with human skin fibroblast cell line (HSF), CHMP4B, TNFAIP3 levels were statistically significantly higher and HMGB1 was lower in synovial sarcoma and liposarcoma cell lines.
