Given the different sample sources between MDS patients and healthy controls (BM vs. PB), we also assessed the impact of this factor through a comparative mRNA expression analysis of the ATG, DRAM, AMBRA1, PI3KC3, UVRAG, TGM2, BCL2, CASP7, and LC3B genes in BM and PB samples from three MDS patients. The gene discussed is DRAM1; the disease is myelodysplastic syndrome.
