Abstract

Allicin, the main active principle associated with Allium sativum chemistry, has various antitumor activities. However, to the best of our knowledge, there is no available information to address the anti‑invasive effect and associated mechanism in lung adenocarcinoma. In the present study, cell viability assay, cell adhesion assay, western blot analysis, Transwell migration and invasion assays and reverse transcription‑quantitative polymerase chain reaction were performed. Allicin was identified to inhibit the adhesion, invasion and migration of lung adenocarcinoma cells in a dose‑dependent manner, accompanied by decreasing mRNA and protein levels of matrix metalloproteinase (MMP)‑2 and MMP‑9. Conversely, the mRNA and protein levels of tissue inhibitor of metalloproteinase (TIMP)‑1 and TIMP‑2 were increased in a dose‑dependent manner. Furthermore, it was revealed that allicin treatment significantly suppressed the phosphorylation of AKT (P<0.05), but not the total protein expression of AKT. Combined treatment with LY294002, an inhibitor of phosphoinositide 3‑kinase (PI3K)/AKT signaling, and allicin led to the synergistic reduction of MMP-2 and MMP-9 expression, followed by an increase in TIMP‑1 and TIMP‑2 expression. The invasive capabilities of lung adenocarcinoma cells were also suppressed. However, insulin‑like growth factor‑1 (an activator of PI3K/AKT signaling) reversed the effects of allicin on cell invasion and expression of MMP‑2, MMP‑9, TIMP‑1 and TIMP‑2. The present study concluded that allicin may inhibit invasion of lung adenocarcinoma cells by altering TIMP/MMP balance, via reducing the activity of the PI3K/AKT signaling pathway. This indicated that allicin may be recognized as an anti‑invasive agent for lung adenocarcinoma treatment.
