Abstract

Background/aims: A disintegrin and metalloprotease (ADAM) 17 has been reported to be implicated in cancer cells invasion. Nevertheless, its potential role in lung adenocarcinoma has not been addressed clearly.

Methods: RT-PCR and Western blot were used to detect the expression of miR-326 and ADAM17 in lung adenocarcinoma samples (n=73). miR-326 mimics and inhibitor were tansfected in human A549 and SPCA1 cell lines. The transwell assay was used to detect the cell invasive ability. The regulation mechanism was evaluated by luciferase reporter assay. The markers of (epithelial-to-mesenchymal transition) EMT were detected by using Western blot assay.

Results: We found increased expression of ADAM17 in lung adenocarcinoma and cell lines. In vitro, up-regulation of ADAM17 promoted cells invasion, while silencing of ADAM17 inhibited cells invasion. Meanwhile, ADAM17 could affect the markers of EMT. Furthermore, we confirmed that ADAM17 is a target of miR-326, which is involved in EMT and cells invasion.

Conclusions: These findings revealed that ADAM17, a target of miR-326, promoted EMT-induced cells invasion in lung adenocarcinoma.
