Melanoma is a serious form of skin cancers begins in the melanocyte. Micro-RNAs are small noncoding RNA with 19 to 25 nucleotides in length involves in the regulation of a wide range of biological processes. MicroRNAs are affected by an aberrant epigenetic alteration in the tumors that may lead to their dysregulation and formation of cancer. Recently, dysregulation of numerous microRNAs has been reported in different types of cancer. The present study focused on the role of miR-143 in carcinogenesis of melanoma cancer. Here, we evaluated the expression level of miR-143 in three melanoma cell lines in comparison with the normal human epidermal melanocyte cell line. Then, miR-143 gene plasmid transfected into the WM115 cell line, for having the lowest expression of miR-143. In addition, the effect of miR-143 transfection on mRNA and protein levels of metastasis-related genes was performed along with MTT assay, wound healing assay, and flow cytometry. The results showed that mRNA and protein expression levels of metastasis-related genes including MMP-9, E-cadherin, Vimentin, and CXCR4 have been reduced following transfection of miR-143. Moreover, the results of the scratch test showed that miR-143 re-expression inhibited cell migration. Also, the role of miR-143 in the induction of apoptosis and inhibition of proliferation by flow cytometry and MTT was confirmed. As a result, the present study showed that miR-143 was involved in metastatic and apoptotic pathways, suggesting that miR-143 acts as a tumor-suppressor microRNA in melanoma cancer.

miR-143在体外作为黑色素瘤癌细胞迁移和增殖的抑制剂以及细胞凋亡的诱导剂

黑色素瘤是一种严重的皮肤癌,起源于黑色素细胞。Micro-RNA 是长度为 19 到 25 个核苷酸的小型非编码 RNA,涉及广泛的生物过程的调节。MicroRNA 受到肿瘤中异常表观遗传改变的影响,这可能导致它们的失调和癌症的形成。最近,在不同类型的癌症中报道了许多 microRNA 的失调。本研究的重点是 miR-143 在黑色素瘤癌变中的作用。在这里,我们评估了 miR-143 在三种黑色素瘤细胞系中与正常人表皮黑色素细胞系相比的表达水平。然后,将miR-143基因质粒转染到WM115细胞系中,miR-143的表达最低。此外,miR-143 转染对转移相关基因 mRNA 和蛋白质水平的影响与 MTT 测定、伤口愈合测定和流式细胞术一起进行。结果表明,转染miR-143后,转移相关基因(包括MMP-9、E-cadherin、Vimentin和CXCR4)的mRNA和蛋白表达水平降低。此外,划痕试验的结果表明 miR-143 的重新表达抑制了细胞迁移。此外,通过流式细胞术和 MTT 证实了 miR-143 在诱导细胞凋亡和抑制增殖中的作用。因此,本研究表明 miR-143 参与转移和凋亡途径,表明 miR-143 在黑色素瘤癌症中充当肿瘤抑制因子 microRNA。和流式细胞术。结果表明,转染miR-143后,转移相关基因(包括MMP-9、E-cadherin、Vimentin和CXCR4)的mRNA和蛋白表达水平降低。此外,划痕试验的结果表明 miR-143 的重新表达抑制了细胞迁移。此外,通过流式细胞术和 MTT 证实了 miR-143 在诱导细胞凋亡和抑制增殖中的作用。因此,本研究表明 miR-143 参与转移和凋亡途径,表明 miR-143 在黑色素瘤癌症中充当肿瘤抑制因子 microRNA。和流式细胞术。结果表明,转染miR-143后,转移相关基因(包括MMP-9、E-cadherin、Vimentin和CXCR4)的mRNA和蛋白表达水平降低。此外,划痕试验的结果表明 miR-143 的重新表达抑制了细胞迁移。此外,通过流式细胞术和 MTT 证实了 miR-143 在诱导细胞凋亡和抑制增殖中的作用。因此,本研究表明 miR-143 参与转移和凋亡途径,表明 miR-143 在黑色素瘤癌症中充当肿瘤抑制因子 microRNA。划痕试验的结果表明 miR-143 的重新表达抑制了细胞迁移。此外,通过流式细胞术和 MTT 证实了 miR-143 在诱导细胞凋亡和抑制增殖中的作用。因此,本研究表明 miR-143 参与转移和凋亡途径,表明 miR-143 在黑色素瘤癌症中充当肿瘤抑制因子 microRNA。划痕试验的结果表明 miR-143 的重新表达抑制了细胞迁移。此外,通过流式细胞术和 MTT 证实了 miR-143 在诱导细胞凋亡和抑制增殖中的作用。因此,本研究表明 miR-143 参与转移和凋亡途径,表明 miR-143 在黑色素瘤癌症中充当肿瘤抑制因子 microRNA。
