Purpose: Burkitt lymphoma (BL) is a B-cell lymphoma frequently diagnosed in children. It is characterized by MYC translocations, which lead to the constitutive expression of the MYC oncogene. MYC contributes to miR-29 repression through an E-box MYC binding site on the miR-29b-1/miR-29a promoter region. We evaluated the role of miR-29a/b/c and their predicted targets in BL pathogenesis.
Methods: Mature sequences of miR-29a/b/c were transfected to the BL cell lines BL41 and Raji, and evaluated for DNMT3B, MCL1, BIM, CDK6, AKT and TCL1 protein expression as well as for MCL-1 and CDK6 mRNA expression. BL cells were treated with 5-aza-2'-deoxycytidine (decitabine) and evaluated for miR29 expressions and methylation status. DNMT3B inhibition was performed by DNMT3B siRNA.
Results: Ectopic expression of miR-29s in BL cells decreased CDK6, DNMT3B, TCL1 and MCL-1 protein levels, but CDK6 and MCL-1 mRNA expression was unaffected by miR-29. Decitabine enhanced miR-29 expression levels and decreased CDK6 protein expression. Additionally, inhibition of DNMT3B by siRNA increased miR-29a/b expression. Notably, the miR-29a/b1 and miR-29b2/c promoter genes showed methylated CpG sequences that were demethylated after decitabine treatments. Furthermore, MYC-negative tumours had higher levels of miR-29 expression compared with MYC-translocated cases, suggesting that MYC regulates miR-29 in BL tumours.
Conclusions: Our results suggest a significant role for miR-29s in BL pathogenesis in altering the expression of targets involved in critical cancer pathways, such as cell cycle control, apoptosis inhibition and DNA methylation. Moreover, methylation-mediated miR-29 epigenetic silencing may occur during BL development.
