In an attempt to further clarify the role of AR in cisplatin resistance in chondrosarcoma cells, we transfected cis-SW cells with lentivirus expressing AR shRNA (cis-SW-shAR) and Western blot as well as qPCR assays confirmed potent knockdown of AR expression (Figure 2A), with significant inhibition of cell viability and proliferation (Figure 2B, 2C). Here, AR is linked to chondrosarcoma.
