Provided herein are methods for the production of a vector with a size of at least 16 kb from bacterial cells comprising the consecutive steps of a) obtaining bacterial cells comprising a vector with a size of at least 16 kb, comprising an inducible origin of replication, b) inoculating culture medium with the bacterial cells comprising the vector, c) culturing the bacterial cells in the culture medium, d) adding one or more inducers of said inducible origin of replication to the culture medium when the bacterial culture has reached an optical density at 600 nm (OD600) of at least 20, e) further culturing the bacterial cells in the culture medium, f) optionally separating the bacterial cells from the culture medium, and g) recovering the plasmid from the bacterial cells. Also provided herein are vectors with a size of at least 16 kb comprising an inducible origin of replication for use in such methods.

The present invention relates to a covalently closed circular recombinant DNA molecule comprising an origin of replication and an insert comprising a homopolymeric region, wherein the homopolymeric region is located at a distance of least 500 bp from the origin of replication in the direction of replication and/or wherein the insert comprising a homopolymeric region is oriented so that the direction of transcription of the insert is the same as the direction of replication of the origin of replication. The invention further relates to the use of the covalently closed circular recombinant DNA molecule for increasing the yield and/or shortening the fermentation time during fermentation.

The invention provides an expression and secretion system, and methods of using the same, for the expression and secretion of one fusion protein in prokaryotic cells and a second fusion protein in eukaryotic cells. Also provided herein are nucleic acid molecules, vectors and host cells comprising such vectors and nucleic acid molecules.

The present invention relates to the field of fibrosis and inflammation and more particularly to the use of ADAM12 (A Disintegrin and Metalloproteinase 12) inhibitors to prevent or treat inflammation-induced fibrosis. The present invention also relates to the use of ADAM12 as a marker for inflammation-induced fibrosis and to the ablation of ADAM12 expressing cells as therapeutic approach to interfere with the development of pro-fibrotic cells.

Disclosed herein are recombinant nucleic acids encoding tumor antigens fused to immunogenic polypeptides and recombinant Listeria strains comprising the same, methods of preparing same, and methods of inducing an immune response, and treating, inhibiting, or suppressing cancer or tumors comprising administering same.

The invention provides expression vectors for expressing recombinant proteins (e.g., biologics) in mammalian cells. Also provided are host cells comprising the expression vectors, methods of producing the recombinant proteins, and methods of propagating the expression vectors.

The present invention relates to a polynucleotide comprising at least one promoter and an S/MAR element, wherein said S/MAR element is located downstream of said promoter and wherein the nucleic acid sequence of said S/MAR element (S/MAR sequence) comprises at least 3sequence motifs ATTA (SEQ ID NO:1) per 100 nucleotides over a stretch of at most 200 nucleotides; the present invention further relates to a composition and to a host cell comprising said polynucleotide, and to the polynucleotide for use in medicine and for use in treating genetic disease. The present invention also relates to a kit and to a device comprising said polynucleotide, and to methods and uses related to the polynucleotide.

The invention provides hybrid and recombinant phagemid vectors for expressing a transgene in a target cell transduced with the vector. A recombinant phagemid particle comprises at least one transgene expression cassette which encodes an agent which exerts a biological effect on the target cell, characterised in that the phagemid particle comprises a genome which lacks at least 50% of its bacteriophage genome. The invention extends to the use of such phagemid expression systems as a research tool, and for the delivery of transgenes in a variety of gene therapy applications, DNA and/or peptide vaccine delivery and imaging techniques. The invention extends to in vitro, in vivo or in situ methods for producing viral vectors, such as recombinant adeno-associated viruses (rAAV) or lentivirus vectors (rLV), and to genetic constructs used in such methods.

The present invention concerns nucleic acids of interest for modulating the microbiome of a host, to vectors encoding said nucleic acids and to methods for in vivo modulating the microbiome of a subject by delivering said nucleic acid of interest.

The present invention relates to the production and use of covalently closed circular (ccc) recombinant plasmids, and more particulary to vector modifications that improve express of said DNA molecules in the target organism.
