CD38 and chronic myelogenous leukemia, BCR-ABL1 positive: Our study found that both total and phosphor CaMKII-γ proteins were highly expressed in the CD34+/CD38− CML LSCs, but low in CD34− CML cells, CD34+ HSCs from healthy cord bloods and normal blood cells, suggesting that CaMKII-γ might play a critical role in the survival and proliferation of CML LSCs.
