Introduction: We previously performed global miRNA expression profiling of cHL vs. non-Hodgkin lymphoma (NHL) cell lines and sorted germinal centre B-cells (GCB). In the group 79 deregulated miRNAs (p < 0.05) we became particularly interested in upregulated miR-23a-3p, a potential oncomiR, predicted to regulate TNFAIP3 downregulated miR-148a-3p, tumor suppressor miRNA, IL15. Therefore, aimed de...
