The invention belongs to the technical field of medical products, and discloses an application to promotion of squamous cell carcinoma metastasis based on DDX19A. In function, DDX19A is found to promote in-vitro migration and invasion of cervical squamous cell carcinoma cells and in-vivo lung metastasis. In terms of mechanism, overexpression of the DDX19A increases NOX1 expression, increases production of reactive oxygen species (ROS), and induces migration and invasion of the cervical squamous cell carcinoma cells. Rescue experiments show that overexpression of NOX1 can retrieve and knock down cervical cancer squamous cell carcinoma cell invasion and migration and ROS generation caused by DDX19A, and the inventor further discovers that an ROS inhibitor N-acetylcysteine can inhibit DDX19A-induced cervical squamous cell carcinoma cell invasion and migration. Therefore, the DDX19A is proved to promote metastasis of the cervical squamous cell carcinoma by inducing NOX1 to mediate ROS production. Blocking of a DDX19A / NOX1 / ROS axis can be a potential therapeutic target for patients with cervical squamous cell carcinoma.
