Roles of noncoding RNAs in multiple myeloma.

Noncoding RNAs (ncRNAs) constitute a class of nucleic acid molecules within cells that do not encode proteins but play important roles in regulating gene expression, maintaining cellular homeostasis, and mediating cell signaling. This class encompasses microRNAs (miRNAs), long noncoding RNAs (lncRNAs), transfer RNAs (tRNAs), circular RNAs (circRNAs), small interfering RNAs (siRNAs), and others. miRNAs are pivotal in the regulation of gene expression in hematologic malignancies. Aberrant expression of lncRNAs has been confirmed in cancerous tissues, implicating their involvement in carcinogenesis or tumor suppression processes. tRNAs may induce errors or disturbances in protein synthesis, thereby affecting normal cellular function and proliferation. Moreover, circRNAs influence disease progression in tumors by modulating the expression of relevant genes, and siRNAs can inhibit tumor cell proliferation, invasion, and metastasis while inducing apoptosis. This review will elucidate the biological functions of ncRNAs in multiple myeloma (MM) and explore their potential value as therapeutic targets.
