This article aims to explore the effects and possible mechanism of miR-543 on small-cell lung carcinoma (SCLC) cells. The respective levels of miR-543 in lung carcinoma tissues, para-cancerous tissues, human normal lung cells MRC-9, and SCLC cells were detected by RT-qPCR. The proliferation, apoptosis, and migration of SCLC cells were detected after the miR-543 level in SCLC cells was altered by miRNA mimics and inhibitors. The levels of apoptosis-related proteins and potential downstream targeted proteins of miR-543 were detected by western blots. The study revealed that KNTC1 was highly expressed in lung carcinoma tissues and SCLC cells (P < 0.01). It also showed that knockdown of miR-543 can inhibit the proliferation and migration of SCLC cells, induce apoptosis, and increase the level of apoptosis-related proteins. These changes were reversed by the addition of mimics that increased miR-543 levels. The level of miR-543 was positively correlated with the protein expression level of downstream MUC1, β-catenin, and CDC42 in SCLC cells, suggesting that miR-543 may play a role through them. Thus this study concludes that MiR-543 can affect the function of SCLC cells, which may play a crucial role in the presence and development of SCLC. |
