The present invention provides, among other things, multimeric coding nucleic acids that exhibit superior stability for in vivo and in vitro use. In some embodiments, a multimeric coding nucleic acid (MCNA) comprises two or more encoding polynucleotides linked via 3′ ends such that the multimeric coding nucleic acid compound comprises two or more 5′ ends.

Disclosed herein are novel compounds, pharmaceutical compositions comprising such compounds and related methods of their use. The compounds described herein are useful, e.g., as liposomal delivery vehicles to facilitate the delivery of encapsulated polynucleotides to target cells and subsequent iransfection of said target cells, and in certain embodiments are characterized as having one or more properties that afford such compounds advantages relative to other similarly classified lipids.

Provided herein are methods for facilitating or inducing stable transgene integration and expression in a proliferating cell, comprising administering to the cell (i) a recombinant AAV (rAAV) vector comprising the transgene flanked by transposon-derived inverted terminal repeat sequences, which sequences are in turn flanked by AAV-derived inverted terminal repeat regions, and (ii) a source of a transposase that recognises said transposon-derived inverted terminal repeat sequences and directs the genomic integration of the transgene into the genome of the proliferating cell. Also provided are methods and transgene delivery systems for the treatment or prevention of diseases affecting, associated with or characterised by proliferating cells, including paediatric liver diseases, bone marrow diseases and cancer.

Disease model pigs produced by nuclear transplantation, disease model pigs exhibiting stable phenotypes and production methods thereof are provided. Chimeric pigs for producing disease model pigs exhibiting stable phenotypes, genital glands thereof, and germ cells thereof are also provided. A method for producing a genetically modified disease model pig, includes: (a) transplanting a nucleus of a genetically modified cell into cytoplasm of an egg; (b) developing an obtained clonal embryo in a womb of a female pig to obtain an offspring; and mating the obtained offspring or having the offspring undergo sexual reproduction to further obtain the genetically modified offspring as a disease model pig.

Disclosed is a modified microorganism producing putrescine or ornithine, and a method for producing putrescine or ornithine using the same.

Provided herein are methods for facilitating or inducing stable transgene integration and expression in a proliferating cell, comprising administering to the cell (i) a recombinant AAV (rAAV) vector comprising the transgene flanked by transposon-derived inverted terminal repeat sequences, which sequences are in turn flanked by AAV-derived inverted terminal repeat regions, and (ii) a source of a transposase that recognises said transposon-derived inverted terminal repeat sequences and directs the genomic integration of the transgene into the genome of the proliferating cell. Also provide are methods and transgene delivery systems for the treatment or prevention of diseases affecting, associated with or characterised by proliferating cells.

Viral vectors comprising engineered hOTC DNA and RNA sequences are provided which when delivered to a subject in need thereof are useful for treating hyperammonemia, ornithine transcarbamylase deficiency and symptoms associated therewith. Also provided are methods of using hOTC for treatment of liver fibrosis and/or cirrhosis in OTCD patients by administering hOTC.

Sequences of a serotype 8 adeno-associated virus and vectors and host cells containing these sequences are provided. Also described are methods of using such host cells and vectors in production of rAAV particles.
