NR4A3 and myelodysplastic syndrome: We found 2 altered genes of the nuclear receptor subfamily 4, group A (NR4A2 e NR4A3), known to be involved in T-cell apoptosis, brain development, and vascular disease [60], and both showed a simultaneous up-regulation of the protein-coding and the ncRNA from the same locus in MDS-RARS, suggesting that these ncRNAs could be involved in the control of protein coding expression of this gene family in MDS-RARS patients.
