Fig. 4.
Protein cluster analysis. The cluster for proteins that were continuously upregulated and downregulated from K562 cells resistant to ADR (A) and IMA (B).The horizontal axis represents the progress of the model (K-native K562 cells, A1/I1—first phase of model ADR/IMA, A2/I2—second phase of model ADR/IMA, and A3/I3—third phase of model ADR/IMA). The vertical axis represents protein expression changes in each cluster. ADR, adriamycin; IMA, imatinib.
