Whole exome sequencing of human MDS/AML OCI-M2 and patient-derived bone marrow cell lines treated with 5-azacytidine
The whole exome sequencing experiment is part of the study: “Analysis of 5-azacytidine resistance models reveals a set of targetable pathways”. In the study we generated myelodysplastic syndrome/acute myeloid leukemia (MDS/AML) OCI-M2 cell lines as well as patient-derived bone marrow cell lines that are resistant to hypomethylating therapy by 5-azacytidine (AZA). By integrated analysis of expression and mutation data obtained from these samples we have identified multiple signaling pathways whose modulation by specific small molecule inhibitors significantly block proliferation of AZA-resistant cell lines without increasing their sensitivity to AZA. The understanding of the molecular mechanisms which characterize the AZA-R phenotype can be used for broadening therapeutic options at progressing states during AZA therapy.
