Chinese hamster ovary (CHO) cells are a valuable tool and are widely used for recombinant protein production in the pharmaceutical industry; however, there remains a need to improve the recombinant protein expression levels. In this study, authors test the effectiveness of various 3′untranslated regions (UTRs) in promoting production of a naturally secreted luciferase. They show that manipulation of expression vectors by inclusion of appropriate 3′UTR sequences is a potentially useful approach to improve recombinant protein expression and yield.
