STRESS granule-associated RNA-binding protein CAPRIN1 drives cancer progression and regulates treatment response in nasopharyngeal carcinoma.

ABSTRACT: Nasopharyngeal carcinoma (NPC) is a common malignancy of the head and neck that is mainly diagnosed in southern China and Southeast Asia, with a strong etiological link to Epstein‒Barr virus infection. Those with advanced-stage disease have a significantly worse prognosis. There is an urgent need to identify novel therapeutic targets for the recurrent or metastatic nasopharyngeal carcinoma. With a particular focus on Cell Cycle Associated Protein 1 (CAPRIN1), one of the important RNA-binding proteints associated with stress granule formation, we used RT‒qPCR and immunohistochemistry to validate CAPRIN1 expression in NPC tissues and cell lines. Further, CAPRIN1 expression was knocked down using siRNA, and the effect on cell proliferation and migration was systematically assessed by in vitro
