GADD45G and myelodysplastic syndrome: We constructed GADD45γ eukaryotic expression vector and GADD45γ shRNA interference plasmid, and transfected MDS cell line SKM‐1 and American ATCC mouse normal bone marrow cell line (class B) HS‐5, respectively, to study the effect of GADD45γ on cell proliferation and apoptosis.
