Supplementary Material for: MicroRNA Profiling in Chemoresistant and Chemosensitive Acute Myeloid Leukemia

MicroRNA (miRNA) deregulation is associated with progression and treatment outcome in various types of cancers. To identify miRNAs related to therapeutic response, we applied an miRNA microarray followed by PCR verification of 33 available diagnostic bone marrow core biopsies from 33 acute myeloid leukemia patients including 15 chemoresistant and 18 chemosensitive patients. We found 3 significantly upregulated miRNAs, miR-363, miR-532-5p and miR-342-3p, related to therapeutic response (q &lt; 0.05). Further validation of miR-532-5p and miR-363 expression by quantitative RT-PCR confirmed microarray analysis results. Genes targeted by miR-363 include <i>RGS17</i> and <i>HIPK3,</i> both reported to be associated with drug response<i>.</i>
