BCL2L10 and myelodysplastic syndrome: In a second cohort (cohort 2 / frozen samples), retrospective comparison of BM samples from low risk MDS patients (n=14), AZA-sensitive (n=21) or AZA-resistant patients (n=10) showed that the counts of BCL2L10 positive cells of low risk MDS patients was 0% (0-11), whereas AZA-resistant patients had significantly higher numbers of BCL2L10 positive cells as compared to AZA-sensitive patients (33% versus 10%, p<0.0001) (Figure 5B).
