Abstract: The present disclosure provides a modified human OTC protein having improved properties for the treatment of OTC deficiency in a patient. Preferably, the protein of the disclosure is produced from a codon optimized mRNA suitable for administration to a patient suffering from OTC deficiency wherein upon administration of the mRNA to the patient, the protein of the disclosure is expressed in the patient in therapeutically effective amounts to treat OTC deficiency. The present disclosure also provides codon optimized mRNA sequences encoding wild type human OTC comprising a 5? UTR derived from a gene expressed by Arabidopsis thaliana for use in treating OTC deficiency in a patient.

Abstract: Lipid formulations that encapsulate messenger RNA (mRNA) are provided herein. The mRNA can be used to express CFTR protein in vitro or in vivo. The lipid formulations can be administered via inhalation to treat cystic fibrosis.

Abstract: The present disclosure provides a modified human protein having improved in vivo stability. The modified human protein has been altered from a wild-type human protein at either at least one ubiquitination site, at the signal peptide portion, or both. The protein of the disclosure can be produced from a codon optimized mRNA suitable for administration to a patient suffering from deficiency of the wild-type protein, wherein upon administration of the mRNA to the patient, the modified protein of the disclosure is expressed in the patient in therapeutically effective amounts.

Abstract: Nucleotides encoding a Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein are provided herein. Also describe are mRNA constructs that can be used to express CFTR protein in vitro or in vivo. The mRNA constructs can be formulated in a lipid formulation and administered via inhalation to treat cystic fibrosis.

Abstract: This invention provides expressible polynucleotides, which can express a target protein or polypeptide. Synthetic mRNA constructs for producing a protein or polypeptide can contain one or more 5? UTRs, where a 5? UTR may be expressed by a gene of a plant. In some embodiments, a 5? UTR may be expressed by a gene of a member of Arabidopsis genus. The synthetic mRNA constructs can be used as pharmaceutical agents for expressing a target protein or polypeptide in vivo.
