The study found that TNS1 is upregulated in NSCLC cells and tissues, and is associated with the prognosis of NSCLC patients. Additionally, TNS1 promotes the growth and metastasis of NSCLC cells via the Akt/mTOR/RhoA pathway. miR-152 targets TNS1 to influence the progression of NSCLC.
Aim: The purpose of the present study was to explore the function and mechanism of tensin (TNS1) in non-small cell lung cancer (NSCLC) progression. Methods: The expression of TNS1 in NSCLC cells and tissues was assessed by RT-PCR and Western blot. Besides, Kaplan-Meier survival analysis was recruited to explore the association between TNS1 and NSCLC. Cell growth was analyzed by MTT and flow cytometry assay, while cell metastasis was determined by wound healing and transwell assays. The targeting relationship between TNS1 and miR-152 was assessed by luciferase activity assays. And Western blot was employed to determine the expression of related proteins of Akt/mTOR/RhoA pathway. Results: TNS1 level was boosted in NSCLC cells and tissues, related to the prognosis of NSCLC patients. Furthermore, it was proved that TNS1 promoted the growth and metastasis of NSCLC cells via Akt/mTOR/RhoA pathway. And miR-152 targeted TNS1 to affect the progression of NSCLC. Conclusion: miR-152/TNS1 axis inhibits the progression of NSCLC by Akt/mTOR/RhoA pathway.
