Abstract: The invention relates to vector constructs for an HIV-specific gene therapy. The expression of transgenes is coupled with an infection of the cell with HIV while the transcription of the transgene is controlled by a transcription control region derived from HIV. In addition, the transgene is improved with regard to RNA stability and expression efficiency by modifying the nucleotide sequence.

Abstract: The present invention relates to a method for identifying frameshift mutations in coding nucleic acid sequences.

Abstract: The invention relates to a method for optimizing a nucleotide sequence for expression of a protein on the basis of the amino acid sequence of the protein, in which for a particular region there is specification of a test sequence with m optimization positions on which the codon occupation is varied, a quality function being used to ascertain the optimal codon occupation on these optimization positions, and one or more codons of this optimal occupation being specified as codons of the optimized nucleotide sequence. These steps are iterated, with the codons of the optimized nucleotide sequence which are specified in the preceding steps remaining unchanged in subsequent iteration steps. The invention additionally relates to a device for carrying out this method.

Abstract: The present invention relates to the use a Phyllanthus extract or a fraction thereof or a gallotannin or a combination of gallotannins for the preparation of a pharmaceutical composition for the prevention or treatment of retrovirus related diseases associated with a nucleosidic inhibitor-resistant retrovirus and/or a non-nucleosidic inhibitor-resistant retrovirus. Preferably, the retrovirus is a human immunodeficiency virus (HIV). In accordance with the present invention, it is further preferred that said gallotannin or combination of gallotannins is or comprises corilagin and/or geraniin and another ellagitannin. Further preferred is that said Phyllanthus is Phyllanthus amarus.
