Abstract: The present disclosure provides FGF1 mutant proteins, which selectively bind to/activate FGFR1b. Also provided are nucleic acid molecules that encode such proteins, and vectors and cells that include such nucleic acids. Methods of using the disclosed FGF1 mutants to reduce blood glucose in a mammal and treat a metabolic disorder are provided.

Abstract: The present disclosure provides FGF1 mutant proteins, which include an N-terminal deletion, point mutation(s), or combinations thereof, as well as FGF1-vagus targeting chimeric proteins which include an FGF1 portion (e.g., native FGF1 or mutant FGF1) and a portion that targets the chimera to the vagus nerve (e.g., GLP or exendin-4). Also provided are nucleic acid molecules that encode such proteins, and vectors and cells that include such nucleic acids. The disclosed FGF1 mutants and FGF1-vagus targeting chimeric proteins can reduce blood glucose in a mammal, and in some examples are used to treat a metabolic disorder.

Abstract: The present disclosure provides FGF1 mutant proteins, which include an N-terminal deletion, point mutation(s), or combinations thereof. In some examples, the mutant FGF1 proteins have reduced mitogenic activity. Also provided are nucleic acid molecules that encode such proteins, and vectors and cells that include such nucleic acids. The disclosed FGF1 mutants can reduce blood glucose in a mammal, and in some examples are used to treat a metabolic disorder.
