Natural selection drives extremely rapid evolution in antiviral RNAi genes

There is now new evidence that animals in fact do an impressive job of keeping up in the ongoing evolutionary arms race between viruses and their hosts.

A putative RNA-interference-based immune system in prokaryotes

Researchers have used computational methods to predict what could be a prokaryotic RNA-silencing mechanism similar to the eukaryotic RNA- interference system.

Two drug giants team up to develop new bird flu therapy

Two major drug companies have teamed up in order to develop a treatment for pandemic flu strains.

Sirna Therapeutics awarded patent covering large-scale synthesis of RNAi-based therapeutics

Sirna Therapeutics has announced that the United States Patent and Trademark Office (USPTO) has granted Sirna U.S. Patent No. 6,989,442 for the chemical synthesis and manufacturing of ribonucleic acids (RNA).

Tissue-specific RNAi reveals that WT1 expression in nurse cells controls germ cell survival and spermatogenesis

Researchers at The University of Texas M. D. Anderson Cancer Center say they have jumped a significant hurdle in the use of RNA interference (RNAi), believed by many to be the ultimate tool to both decode the function of individual genes in the human genome and to treat disease.

Sleeping sickness parasite shows how cells divide their insides

Researchers at Yale have brought to light a mechanism that regulates the way an internal organelle, the Golgi apparatus, duplicates as cells prepare to divide, according to a report in Science Express.

CSIRO's RNAi 'gene silencing' patents strengthened

The patent landscape for RNAi 'gene silencing' - including CSIRO's hairpin RNAi technology - has been significantly clarified following the resolution of several opposition and re-examination cases in Australia.

Mechanism of X-chromosome dosage compensation in Drosophila

In Drosophila, like in humans, male cells have a single X chromosome, while female cells have two. Researchers have long debated over how X and autosomal chromosome gene expression is equalized between the sexes (generally regarding two different models, known as the activation model and the inverse model).

Ubiquitin ligase Rnf6 may be involved in oncogenesis

In a recent study, Dr. Ingolf Bach and colleagues from the University of Massachusetts Medical School, Worcester and the University of Hamburg describe a novel role for the ubiquitin/proteosome protein degradation pathway in the regulation of local actin dynamics in neurons.

RNAi therapeutic successful for treatment of SARS respiratory virus in Rhesus Macaque

Intradigm Corporation announced today its collaboration with Chinese academic and biotech groups has achieved clear evidence of prophylactic and therapeutic effects of siRNA (small interfering RNA) agents in Rhesus monkey to treat SARS coronavirus (SCV) respiratory infection.

Patent for determining gene function quickly with Hellsgate

A CSIRO innovation for determining gene function quickly and with virtually 100 per cent efficiency has been granted a US patent clarifying its leadership position in the international gene silencing arena.

C. elegans has similar virus-fighting mechanism as humans and can be used in research

Researchers at the University of California, Riverside have discovered that a simple worm, called C. elegans, makes an excellent experimental host for studying some of the most virulent viruses that infect humans.

Preliminary molecular diagram of the early stages of embryo formation

A team of genomic researchers headed by biologists at New York University's Center for Comparative Functional Genomics, in collaboration with researchers at Harvard University, the Max Planck Institute, and Cenix Biosciences, has mapped out a preliminary molecular diagram of the early stages of embryo formation, offering for the first time a global look at how a single cell begins its path into a multi-cellular organism.

Scientists identify protein that may inhibit cellular movement

Scientists from the University of North Carolina at Chapel Hill School of Medicine and the UNC Lineberger Comprehensive Cancer Center have identified a protein that may inhibit cellular movement, or migration.

Sigma-Aldrich licenses RNAi patent estate from Alnylam

Sigma-Aldrich Corporation and Alnylam Pharmaceuticals announced today that Alnylam has granted Sigma-Aldrich a non-exclusive license to provide research products and services in RNA interference (RNAi) under the Kreutzer-Limmer patent family.

A systematic search through human genes

...has begun at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. Working within the MitoCheck consortium that includes 10 other institutes throughout Europe, the EMBL scientists will silence all human genes, one-by-one, to find those involved in cell division (mitosis) and to answer fundamental questions of how cell division is regulated.

Researchers use RNAi libraries to identify regulators of apoptosis and chemoresistance

Using targeted RNA interference, or RNAi libraries, researchers at Harvard Medical School describe the first large-scale classification of kinase and phosphatase gene families on the basis of their role in apoptosis and cell survival. This study appears in the June issue of Nature Cell Biology.
