Brief summary: MiRNAs are noncoding RNAs (ncRNAs) that drive post-transcriptional negative regulation of gene expression by promoting the degradation or translational blockade of their target mRNAs. MiRNAs are 21-24-nucleotide-long RNA molecules that are processed from longer RNA precursors (pri-miRNAs) , and either the 5' or the 3' strand of the mature miRNA duplex is loaded into the Argonaute (AGO) family of proteins to form a miRNA-induced silencing complex (miRISC) When bound to AGO proteins, mature miRNAs destabilize or inhibit the translation of partially complementary target mRNAsMiRNA-124 has been shown to be a tumor suppressor, and a decrease in its expression level is typical of tumors of various localization, but there is no evidence of the role of miRNA-124 in the development of NHL . There are a number of studies reflecting the involvement of miRNA-124 in hematopoiesis. Liu et al. showed that miRNA-124 regulates Tip110 that is involved in the differentiation of hematopoietic stem cellsThe let-7 family has been shown to influence the pathogenesis of a variety of hematological malignancies through the changing expression of a number of oncogenic pathways, particularly those related with MYC and that might affect hematopoietic carcinogenesis through the modulation of inflammatory pathways
