The present invention is related to a nucleic acid, preferably binding to C5a, selected from the group comprising type A nucleic acids, type B nucleic acids, type C nucleic acids, type D nucleic acids and nucleic acids having a nucleic acid sequence according to any of SEQ. KXNo. 73 to 79.
Abstract:
The invention provides novel oligonucleotide-based compounds that individually provide distinct immune response profiles through their interactions as agonists with TLR9. The TLR9 agonists according to the invention are characterized by specific and unique chemical modifications, which provide their distinctive immune response activation profiles.
Abstract:
The invention provides immunostimulatory compositions and methods for their use. In particular, the immunostimulatory compositions of the invention include RNA-like polymers that incorporate an immunostimulatory sequence motif and at least one chemical modification to confer improved stability against nuclease degradation and improved activity. Specific modifications involving phosphate linkages, nucleotide analogs, and combinations thereof are provided. Compositions of the invention optionally include an antigen and can be used to stimulate an immune response. Also provided are compositions and methods useful for treating a subject having an infection, a cancer, an allergic condition, or asthma. Modified oligoribonucleotide analogs of the invention are believed to stimulate Toll-like receptors TLR7 and TLR8.
Abstract:
The present invention relates to a double-stranded ribonucleic acid (dsRNA) for inhibiting the expression of an anti-apoptotic gene, comprising an antisense strand having a nucleotide sequence which is less that 25 nucleotides in length and which is substantially complementary to at least a part of an apoptotic gene, such as a Bcl gene. The invention also relates to a pharmaceutical composition comprising the dsRNA together with a pharmaceutically acceptable carrier; methods for treating diseases caused by the expression of an anti-apoptotic gene using the pharmaceutical composition; and methods for inhibiting the expression of an anti-apoptotic gene in a cell.
Abstract:
While the foregoing invention has been described in some detail for purposes of clarity and understanding, it will be appreciated by one skilled in the art from a reading of this disclosure that various changes in form and detail can be made without departing from the true scope of the invention and appended claims.
Abstract:
A new method for an antibiotic-free selection of genetically modified cells is described. It is shown that antisense molecules targeted to an essential cellular gene inhibits growth and is suited as an agent for growth selection of cells transformed with a plasmid carrying an altered version of the essential gene. The results show that antisense molecules may be used for antibiotic-free selection of desired transformed microbes when targeted against an essential microbial gene. This technology is useful in genetic engineering for research growth and isolation of transformed organisms, and for industrial growth maintenance of transformed organisms, e.g. in the production of genetically engineered proteins as an environmentally safer alternative to traditional selection methods based on antibiotics.
Abstract:
As an effective therapy for proliferative skin and eye diseases such as psoriasis and proliferative diabetic retinopathy, this invention provides ribozymes and ribozyme delivery systems which cleave RNA encoding cytokines involved in inflammation, matrix metalloproteinases, a cyclin, a cell-cycle dependent kinase, a growth factor, or a reductase.

Abstract:
This invention provides compositions and methods for modulating expression of members of the human Rho gene family, which encode low molecular weight GTPases that act as molecular switches in signal transduction. In preferred embodiments, Rho family members include RhoA, RhoB, RhoC, RhoG, Rac1 and cdc42. This invention is also directed to methods for inhibiting hyperproliferation of cells; these methods can be used diagnostically or therapeutically. Furthermore, this invention is directed to treatment of conditions associated with expression of the human Rho family members, particularly in hyperproliferative disorders.
