To examine the therapeutic role of Akt isoform specific inhibitors in the treatment of GC-resistant lymphoid tumor cells, we treated CCRF-CEM cells with DEX and A-674563 (Akt1 inhibitor), CCT128930 (Akt2 inhibitor), or Akti1/2 (Akt1/2 inhibitor). This evidence concerns the gene AKT1 and lymphoid neoplasm.
