Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA molecules, 20-25 nucleotides in length, that play a variety of roles in biology. Most notably, siRNA is involved in the RNA interference (RNAi) pathway, where it interferes with the expression of a specific gene. In addition to their role in the RNAi pathway, siRNAs also act in RNAi-related pathways, e.g., as an antiviral mechanism or in shaping the chromatin structure of a genome; the complexity of these pathways is only now being elucidated.
Researchers at Penn State College of Medicine have identified the mechanism by which the most mutated gene in melanoma, called v599EB-Raf, aids melanoma tumor development demonstrating its importance as a therapeutic target.
Sirna Therapeutics, Inc. has announced the first program to apply RNA interference (RNAi) technology to asthma, a highly prevalent, chronic disease accounting for an estimated $13 billion in healthcare costs in the United States, a number which is forecast to grow considerably by the end of the decade.
The protein, Akt3, appears to be responsible for promoting tumor cell survival and development in 43 percent to 60 percent of non-inherited melanomas.
Ever since the approval of Gleevec in 2001, a cancer-cell-specific drug used to treat chronic myelogenous leukemia (CML), the field of cancer therapeutics has been rushing full speed into the era of so-called "targeted" medicines.
Sirna Therapeutics has announced the publication of preclinical studies evaluating RNA interference-based therapies for a class of inherited neurodegenerative diseases of the central nervous system (CNS) in the current issue of Nature Medicine.
Cyntellect a privately-held biotechnology company, has announced the issuance of U.S. Patent No. 6,753,161 covering the Company's LaserFect(TM) technology.
A new gene-silencing technique that takes place in the nucleus of human cells, has been demonstrated by researchers at the University of California, San Diego (UCSD) School of Medicine and the VA San Diego Healthcare System.
Gene silencing by RNAi has now been identified as a crucial technology for target validation and therapeutics. By targeting and interfering with messenger RNA (mRNA), RNAi technology blocks the expression of the proteins implicated in disease progression.

Intradigm Corporation, has announced achievement of prophylactic and therapeutic effects of siRNA (small interfering RNA) inhibitors of SARS-CoV in non-human primate cells. The results are published in the June 2004 issue of Antiviral Therapy (International Medical Press).
The siRNA libraries contain 7,500 and 43,800 siRNA template sequences that target 1,500 and 8,500 well-characterized human genes, respectively.
Pharmaceutical science leaders from the FDA, research institutions and top pharmaceutical companies will gather at the 2004 AAPS National Biotechnology Conference, AAPS' spring annual meeting.
Prime Standard QIA a leading supplier of products and technologies for nucleic acid separation, purification and handling today announced that it has launched a series of off-the-shelf human library siRNA sets, covering a broad gene family selection including kinases, GPCRs, apoptosis related genes, and oncogenes, to name a few.
