It is highly expressed in various cancers such as lung cancer, gastric cancer, and breast cancer, and participates in the proliferation, metastasis, and recurrence of tumor cells. In this study, the lung cancer cell line A549 was used as the research object to explore the regulatory mechanism of TrkB activation, in order to provide new targets and strategies for the treatment of lung cancer. The specific research contents include: 1) analyze the expression and activation of TrkB in A549 cells; 2) screen TrkB activators and inhibitors, and explore their effects on the proliferation and apoptosis of A549 cells; 3) use Western blot and other techniques to analyze the changes in related signaling pathways after TrkB activation, explore their biological significance in lung cancer, and find new intervention targets. This study has certain theoretical and practical value for revealing the regulatory mechanism of TrkB activation in lung cancer cells and developing new treatment strategies.【Keywords】TrkB; lung cancer; signal transduction pathway; treatment strategies
