MYC and Burkitt lymphoma: Interestingly, when we compared the miRNA profiling of MYC translocation-positive versus MYC translocation-negative BL cases, we identified four miRNAs differentially expressed, of which hsa-miR-513a-5p and hsa-miR-628-3p were up-regulated and two miR-29 family members (hsa-miR-29a and hsa-miR-29b) were down-regulated in BL cases lacking the MYC translocation.
