The tissue samples of cisplatin-resistant and sensitive patients with human osteosarcoma were obtained through chemosensitivity testing before. Five typical differentially expressed proteins of cisplatin-resistant and sensitive osteosarcoma tissue samples were analyzed by two-dimensional electrophoresis and the relevant differentially expressed proteins were obtained before. By Western Blot techinique in vitro, Two three-representative-tissues on cisplatin-resistant and sensitive osteosarcoma were chosen to test which is the differently expressed of 5 proteins. It is concluded that ALDOA and PGK1 may be the right markers in cisplatin chems in trating human osteosarcoma.
