miR ‑144‑3p inhibits the proliferation, migration and angiogenesis of multiple myeloma cells by targeting myocyte enhancer factor 2A.

miR‑144‑3p inhibits the proliferation, migration and angiogenesis of multiple myeloma cells by targeting myocyte enhancer factor 2A. Int J Mol Med. 2020 Sep;46(3):1155-1165 Authors: Tian F, Wang H, Ma H, Zhong Y, Liao A Abstract Multiple myelomas (MM) are the second most common haematological malignancy, for which no curative treatments have been reported to date. MicroRNAs (miRNAs or miRs) have recently been shown to be involved in the proliferation of MM cells. However, the molecular mechanisms through which miRNAs regulate migration and angiogenesis in MM are poorly understood. Accordingly, the present study evaluated the role of miR‑144‑3p in MM. miR‑144‑3p exhibited a lower expression in patients with MM and in MM cell lines compared with normal cells (mononuclear cells derived from bone marrow). The transfection of miR‑144‑3p into MM cells inhibited proliferation, migration and angiogenesis, and induced cell cycle arrest and apoptosis compared to the control cells. Furthermore, miR‑144‑3p suppressed the transcription and translation of the myocyte enhancer factor 2A (MEF2A) gene and disrupted the expression of vascular endothelial growth factor. The knockdown of MEF2A significantly inhibited the proliferation, migration and angiogenesis of MM cells. However, the overexpression of MEF2A reversed these effects. On the whole, the findings of the present study demonstrate that miR‑144‑3p exerts antitumour...
