Instead, MCM2 expression levels showed a positive correlation with the cleaved caspase‐3‐positive apoptotic cell ratio.46In vitro experiments using MDS‐derived hematopoietic cell lines demonstrated that MCM2 overexpression induced apoptosis in MDS hematopoietic cells.46 Thus, the function of MCM2 was completely different between hematopoietic cells from patients with MDS and those from control bone marrow/AML cells. The gene discussed is MCM2; the disease is myelodysplastic syndrome.
