| description | Objective: Long noncoding RNAs (lncRNAs) are potential biomarkers for cancers. Nevertheless, the ability of long noncoding RNA lung cancer-associated transcript 1 in patients with multiple myeloma remains unknown. The purpose of this current study was to figure out its function in multiple myeloma. Methods: Firstly, the expression of long noncoding RNA lung cancer-associated transcript 1 in cancer or normal tissues and serum from patients with multiple myeloma and normal donors was detected. Secondly, the expression of long noncoding RNA lung cancer-associated transcript 1 was overexpressed or silenced in U266 and H929 cells, respectively to detect changes of proliferation and apoptosis in multiple myeloma in vitro . Subsequently, the expression of transforming growth factor-β signaling pathway-related proteins was detected by western blot analysis. Finally, the effect of long noncoding RNA lung cancer-associated transcript 1 on the growth of multiple myeloma cells in vivo was evaluated by tumor xenograft in nude mice. Results: Long noncoding RNA lung cancer-associated transcript 1 was increased in cancer tissues and serum of patients with multiple myeloma as well as multiple myeloma cells, which was correlated with dismal prognosis of patients with multiple myeloma. Overexpression of long noncoding RNA lung cancer-associated transcript 1 promoted the activity of U266 and H929 cells, while inhibition of long noncoding RNA lung cancer-associated transcript 1 suppressed the activity of U266 and H929 cells. In addition, long noncoding RNA lung cancer-associated transcript 1 was found to promote activation of the transforming growth factor-β signaling pathway. Furthermore, long noncoding RNA lung cancer-associated transcript 1 knockdown restricted the growth of multiple myeloma cells in vivo . Conclusion: This study suggests that suppression of long noncoding RNA lung cancer-associated transcript 1 inhibits the activation of transforming growth factor-β signaling pathway, thereby inhibiting the growth of multiple myeloma cells. |
