MicroRNA and multiple myeloma / 中国实验血液学杂志

ABSTRACT

MicroRNA (miRNA) represents a new class of endogenous, non-coding small RNA molecules that functions as gene regulator. They can repress the expression of target genes at the post-transcriptional level by base pairing to the 3'-untranslated region of the respective target mRNAs. miRNA plays important roles in the regulation of cell proliferation, metabolism, apoptosis and differentiation. The dysregulation of miRNA expression contributes to tumorigenesis. This review summarizes recent progress of research on the characteristics and function of miRNA, as well as the role of miRNA in multiple myeloma development, abnormal karyotype in chromosomes and drug-resistant.
