Abstract: The present invention related to nucleic acids designed to prevent the binding of endogenous or exogenous microRNA and diagnostic and therapeutic uses thereof.

Abstract: The invention relates to the use of inhibitors of the expressed proteins of the murine genes and/or their human homologues listed in Table 1 for the preparation of a therapeutical composition for the treatment of cancer, in particular for the treatment of solid tumors of lung, colon, breast, prostate, ovarian, pancreas and leukemia. The invention also relates to the therapeutical compositions comprising the inhibitors and to methods for development of the inhibitor compounds.

Abstract: Biologically active peptides and nucleic acids are identified by a method comprising the following steps: (a) production of a pool of appropriate vectors each containing totally or partly random DNA sequences, (b) efficient transduction of said vectors into a number of identical eukaryotic cells in such a way that a single ribonucleic acid and possibly peptide is expressed or a limited number of different random ribonucleic acids and peptides are expressed by each cell, (c) screening of said transduced cells to see whether some of them have changed a certain phenotypic trait, (d) selection and cloning of said changed cells, (e) isolation and sequencing of the vector DNA in said phenotypically changed cells, and (f) deducing the ribonucleic acid and peptide sequences from the DNA sequence. The peptide sequences may be introduced into or fused to a larger protein, preferably an antibody molecule or a fragment thereof.

Abstract: A library is composed of viral vectors in which each of the vectors (a) involves a peptide expression cassette containing a random nucleotide sequence, (b) transduces a eukaryotic cell to allow expression of the random nucleotide sequence, and (c) is produced by (i) conventional random oligonucleotide synthesis or (ii) random codon synthesis where codons encode an even distribution of random amino acids.

Abstract: A retroviral vector comprising a retrovirus with infectivity for birds and/or mammals in which at least part of the genomic RNA sequences carrying information for the production of viral proteins required in trans for retroviral replication have been replaced by one or more sequences carrying information to be introduced in a target cell chromosome, characterized in that the primer binding site (PBS) has been modified to a sequence that does not allow strong base pairing with the 3' end or other priming sequence in any naturally occurring tRNA. The present application is directed to the tRNA-like primer.
