Exploring microarray data containing gene expression profile of whole blood samples from MPN and healthy donors25 by GEOR2 (https://www.ncbi.nlm.nih.gov/geo/geo2r/), we found that both AURKA and AURKB are upregulated in PMF patients (GEO accession GSE26049; Supplementary Fig. 4), what corroborates previous studies22,23 and provides new insights for AURKB in MPN. Here, AURKB is linked to myeloproliferative disorder.
