The detection of bone marrow samples collected from MDS and MDS-AML patients in the Second Hospital of Shanxi Medical University from 2015 to 2018 showed that EZH2 expression in bone marrow of MDS patients was notably lower than that of healthy non-cancer individuals (p < 0.05; Figure 1A), but EZH2 expression in MDS-AML patients showed a trend of high expression (p < 0.001; Figure 1B). The gene discussed is EZH2; the disease is myelodysplastic syndrome.
