ABSTRACT
Twist related protein 2 (TWIST2) plays an important role in bone development, tumorigenesis, tumour progression and epithelial mesenchymal transition (EMT). At present, there are few reports about the role of TWIST2 in lung cancer, which need to be further explored. Therefore, the purpose of this study is to explore the role and molecular mechanism of TWIST2 in the occurrence and development of lung cancer. The expression of TWIST2 in tissues of patients and cell lines was measured using RT-qPCR and western blotting. MTT and CCK8 assays were used to detect cell proliferation and viability. Western blotting was used to measure the expression of EMT-related proteins, including E-cadherin, N-cadherin, Vimentin and Slug. The results revealed that TWIST2 is lowly expressed in the tissues of lung cancer patients and cell lines. Further studies found that overexpression of TWIST2 significantly induced apoptosis and promoted the expression of E-cadherin, as well as inhibiting the expression of N-cadherin, Vimentin and Slug. More importantly, TWIST2 induced oxidative stress in lung cancer cells. In addition, TWIST2 regulated the FGF21 and AMPK/mTOR signalling pathway, which is involved in the molecular mechanism of the gene in lung cancer cells. We suggest that the mechanism of TWIST2 inhibition of the progression of lung cancer is by regulating the FGF21-mediated AMPK/mTOR signalling pathway.
