摘要:
Disclosed are T7 RNA polymerase variants with enhanced transcriptional activity. T7 RNA polymerase variants are known which have the ability to incorporate modified ribonucleotides into growing RNA molecules. However, these variants have relatively low levels of transcriptional activity. Presented herein are mutations that increase the transcriptional activity of the variants with broad substrate range.

The invention is directed to a method of preparing a nucleic acid sequence with a modified splice site usage profile, which employs the use of a nucleic acid sequence comprising a cryptic splice donor site. The invention also provides a method of producing an alternate form of an RNA molecule encoded by a nucleic acid sequence, which nucleic acid sequence comprises a cryptic splice donor site, a heterologous nucleic acid sequence, and a splice acceptor site.

Methods are provided for making an RNA molecule derived from non-coding chimeric mitochondrial RNAs (ncmtRNAs), in particular antisense non-coding chimeric mitochondrial RNAs (ASncmtRNAs), compositions containing the isolated RNA molecule, methods of causing apoptosis in a cancer cell by contacting the cell with the RNA molecule, and methods of treating cancers by administering the RNA molecule to a subject in need thereof.
摘要:
The present invention relates to a method for producing at least one artificial piRNA, comprising determining an endogenous piRNA population in a cell of an organism of interest; selecting a sub-population of said endogenous piRNA population based on binding of a MILI protein and/or an equivalent PIWI protein to said sub-population; identifying the sequence of at least one piRNA as selected, attaching said at least one piRNA sequence as identified 5' to the sequence of the transcript of a gene of interest, in order to generate at least one piRNA template, and slicing said piRNA template through binding of a MILI protein to said template and subsequent slicing of said bound piRNA template following a binding of MILI protein and/or MIWI2 protein in order to generate at least one artificial piRNA. The method can be used to produce pharmaceutical compositions comprising at least one artificial piRNA as produced according to the invention. Other aspects relates to a method for silencing the expression of a gene of interest in an organism of interest, comprising administering to said organism an effective amount of a pharmaceutical composition according to the invention, and a method for produing a non-genetically modified organism having an artificially silenced expression of at least one gene of interest based on the method of the invention.

The present invention relates to combination therapies for the treatment of a variety of disorders in mammals, including hepatic disorders and cancer. The combination of agents includes naturally-occurring (versus synthetic) oligonucleotides, particularly immunostimulatory oligodeoxynucleotides such as CpG ODNs, obtained from a natural source and one or more extracts from a Gram positive bacteria, such as Lactobacillus spp.

摘要:
The invention relates to a method for production of single-stranded macronucleotides by amplifying and ligating an extended monomeric single-stranded target nucleic acid sequence (target ss ) into a repetitive cluster of double-stranded target nucleic acid sequences (target ds ), and subsequently cloning the construct into a vector (aptagene vector). The aptagene vector is transformed into host cells for replication of the aptagene and isolated in order to optain single-stranded target sequences (target ss ). The invention also relates to single-stranded nucleic acids, produced by a method of the invention.
