Abstract Background: Esophageal squamous cell carcinoma (ESCC) is a fatal disease with poor prognosis. The predominant reason for ESCC-related death is metastasis caused by tumor cell invasion. Human MENA protein is a member of Ena/Vasp family, which plays a critical role during tumor cell invasion. However, the biological effect of MENA in ESCC cell lines remains unclear Methods: In this study, fluorescent quantitative real-time PCR (qRT-PCR) were conducted to detect the mRNA expression of MENA in tumor and para-cancer tissue, CCK-8 assay and clone formation assay were conducted to evaluate cell proliferation activity, Transwell assay and wound-healing assay were conducted to detect the changes of cell invasion and migration capacity, siRNA and MENA expression vector were constructed to explore biological function of MENA in ESCC cell lines. Western blot analysis were conducted to detect the expressions of MENA , molecular markers of epithelial-mesenchymal transition (EMT), Akt, p-Akt, MMP-2 and MMP-9 respectively in ESCC cell line. Results: The qRT-PCR experiment results showed that MENA expression in ESCC tissue of 35 patients was relatively higher than that in tissue adjacent to cancer. CCK-8 assay suggested that tumor cell proliferation capacity was suppressed followed by the knockdown of MENA expression in Mena high ESCC cell TE13 and was potentiated by the overexpression of MENA in Mena low ESCC cell TE1. Transwell assay and wound healing assay demonstrated that interfering in MENA could inhibit TE13 cells invasion and migration capacity by affecting the expressions of Matrix metalloproteinase-2(MMP-2) and Matrix metalloproteinase-9 (MMP-9), in contrast, overexpression of MENA in Mena low ESCC cell TE1 could promote invasion and migration by up-regulated expression of MMP-2 and MMP-9. Western blot analysis indicated that interfering of MENA expression could affect EMT-related molecular markers (E-cadherin, N-cadherin, Snail, Slug), Akt and p-Akt Conclusions: Our study reveal that MENA could promote the ESCC cell invasion and migration by upregulate MMP-2, MMP-9 expression and Akt activation. Meanwhile, interfering of MENA expression could affect EMT in ESCC cells. This indicated that MENA may be a potential molecular therapeutic target for ESCC metastasis

Abstract Background Lung cancer is one of the most common causes of cancer-related deaths in the world, and non-small cell lung cancer (NSCLC) accounts for 85% of it. Studies have reported that microRNA-484 (miR-484) plays an important regulatory role in carcinogenesis and cancer development. Methods 25 clinical NSCLC samples were collected for microRNA array. The funvtion of miR-484 was investigated through Transwell and Mitgration assays. The expression levers of epithelial-mesenchymal transition (EMT) related factors were assessed by Western blot. Results miR-484 was up-regulated in tissues from NSCLC patients relative to tumor-adjacent normal tissues. Knocking-down miR-484 expression in A549 cells significantly suppressed tumor cell invasion and migration, suppressed epithelial-mesenchymal transition (EMT) process by increasing the expression of E-cadherin, and decreasing the expression of N-cadherin, vimentin, and MMP2. Upregulation of miR-484 expression in BEAS-2B normal lung epithelial cells significantly promoted tumor cell invasion and migration, decreased E-cadherin expression levels, and increased N-cadherin, vimentin, and MMP2 expression levels Conclusion miR-484 can promote tumor cell invasion and migration in NSCLC and may be a new target for NSCLC treatment.
