Abstract:
The present invention relates to the provision of genetically modified microbial cells, such as yeast cells with an improved ability for producing L-ornithine and its derivatives. Overproduction of L-ornithine is obtained in the first place by the down-regulation or attenuation of specially selected genes, wherein said genes encode enzymes involved in the L-ornithine consumption and/or degradation pathways. Further L-ornithine production ability is improved by down-regulation, attenuation, deletion or overexpression of specially selected genes, wherein said genes encode enzymes and/or proteins involved in the L-ornithine 'acetylated derivatives cycle', L-glutamate synthesis pathways, subcellular trafficking, TCA cycle, pyruvate carboxylation pathway, respiratory electron- transport chain, and the carbon substrates' assimilation machinery. The invention additionally provides a method to produce L-ornithine with said modified eukaryotic cells.
Abstract:
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.
Abstract:

Abstract:
The present invention relates to a recombinant microorganism capable of producing putrescine and a method for producing putrescine using the same. According to the present invention, NCgl2522 activity of the microorganism, which is transformed to be able to produce putrescine, is enhanced. Therefore, the recombinant microorganism can produce putrescine with a high yield. The recombinant microorganism capable of producing putrescine is characterized in that the microorganism is transformed to have enhanced activity of protein including amino acid with SEQ ID: 21 or 23.
