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. This evidence concerns the gene TGM2 and myelodysplastic syndrome.
