Using a high throughput TaqMan quantitative real-time PCR (RT-qPCR) approach in primary ALCL cases, Liu et al. [31] corroborated the high expression of the miR-17-92 cluster in ALK+ ALCL and found a signature of 7 additional miRNAs that could help to distinguish ALK+ from ALK- ALCL cases (5 upregulated: miR-512-3p, miR-886-5p, miR-886-3p, miR-708, miR-135b; 2 downregulated: miR-146a, miR-155). This evidence concerns the gene ALK and anaplastic large cell lymphoma.
