摘要:
The invention relates to constructs, vectors, relative host cells and pharmaceutical compositions which allow an effective gene therapy, in particular of genes larger than 5Kb by using an improved hybrid dual recombinant AAV vector system.
摘要:
The present invention relates to specific and markedly improved pre-mRNA trans -splicing molecule (RTM) molecules which are designed to correct specific genes expressed within cells to be targeted, and which are associated with epidermolysis bullosa, cystic fibrosis, pachyonychia congenital, and psoriasis or neurodermitis, as well as cancers of the skin. In particular, the RTMs of the present invention are genetically engineered to interact with a specific target pre-mRNA expressed in cells to be targeted so as to result in correction of genetic defects or reprogramming of gene expression responsible for a variety of different skin disorders.
摘要:
Provided is an improved method for controlling gene expression in vivo through the use of a gene switch comprising one or more aptamer sequences operably linked to or incorporated into the untranslated regions (UTRs) of a transgene or nucleotide sequence of interest. Also provided are expression vectors having aptamer sequences located within the 3' UTR, the 5' UTR and between the genes of a multicistronic mRNA, as well as methods of using the expression vectors for controlling or regulating gene expression.
摘要:
An isolated polynucleotide functional as a promoter in eukaryotic cells is disclosed. The isolated polynucleotide includes an endothelial specific enhancer element as detailed herein. Further disclosed is a method of expressing a nucleic acid sequece of interest in endothelial cells.
摘要:
The molecules and methods of the present invention provide a means for in vivo production of a trans-spliced molecule in a selected subset of cells. The pre-trans-splicing molecules of the invention are substrates for a trans-splicing reaction between the pre-trans-splicing molecules and a pre-mRNA which is uniquely expressed in the specific target cells. The in vivo trans-splicing reaction provides a novel mRNA which is functional as mRNA or encodes a protein to be expressed in the target cells. The expression product of the mRNA is a protein of therapeutic value to the cell or host organism a toxin which causes killing of the specific cells or a novel protein not normally present in such cells. The invention further provides PTMs that have been genetically engineered for the identification of exon/intron boundaries of pre-mRNA molecules using an exon tagging method. The PTMs of the invention can also be designed to result in the production of chimeric RNA encoding for peptide affinity purification tags which can be used to purify and identify proteins expressed in a specific cell type.
摘要:
The invention provides an isolated and purified DNA molecule comprising at least one DNA segment, a biologically active subunit or variant thereof, of a circular intermediate of adeno-associated virus, which DNA segment confers increased episomal stability, persistence or abundance of the isolated DNA molecule in a host cell. The invention also provides a composition comprising at least two adeno-associated virus vectors.
