Although previous studies have demonstrated that dysregulation of microRNA
(miR)-126 is associated with the progression of several types of cancer,
including lung cancer, the relationship between miR-126 and lung cancer
metastasis remains unclear. SPC-A1 lung cancer cells were transfected with
miR-126 mimic and negative control using Lipofectamine(®) 3000. Following 2 h,
TGF-?1 was used to induce epithelial-to-mesenchymal transition (EMT). The protein
expression levels of EMT markers: E-cadherin, fibronectin, N-cadherin and
vimentin were detected by western blot analysis or immunofluorescence staining.
The results demonstrated that ectopic expression of miR-126 significantly
suppresses the epithelial-to-mesenchymal transition process, which is considered
to be the initial step of tumor metastasis, in SPC-A1 lung cancer cells. In
addition, lentivirus-delivered miR-126 was demonstrated to endow Lewis lung
carcinoma (LLC) cells with the ability to suppress lung metastasis in vivo.
Previous studies have demonstrated that the molecular signals for this phenomenon
involve the inhibition of the phosphoinositide 3-kinase/protein kinase B/Snail
pathway by miR-126. The protein levels of p-PDK1 (S241) and p-AKT (S473)
decreased in miR-126 mimic transfected SPC-A1 and LLC cells, compared with the
control group, which were detected by western blot analysis. Reverse
transcription-quantitative polymerase chain reaction and western blot analysis
results indicated that the expression of Snail decreased in miR-126 mimic
transfected SPC-A1 and LLC cells. In conclusion, these results revealed an
important role for miR-126 in the regulation of the invasive and metastatic
potential of lung cancer, and suggested a potential application for miR-126 in
lung cancer treatment.
