A new approach to specify RNAi experiments

Issue 3 2006, Past issues / 23 May 2006 / Ina Poser, Project Leader and Frank Buchholz Group Leader, Max Planck Institute of Molecular Cell Biology

Large DNA-sequencing projects such as the Human Genome Project have provided the scientific community with a new challenge: to try to understand the information encoded in the primary sequence of the genome. Studies investigating the role and function of the components of the genome are often called functional genomics.

Is Pharma getting what it needs from RNAi?

Issue 2 2006, Past issues / 24 March 2006 / Steven A. Haney, Department of Biological Technologies, Wyeth Research

Large and small drug development companies have used RNAi intensively for several years now1-3. The adoption of RNAi technologies by drug companies followed fairly closely with their adoption by academic research labs, and as such many of the challenges and problems that were a natural consequence of the rapid expansion of RNAi needed to be worked out by the industrial sector along with academia.

HTS using siRNA libraries

Issue 1 2006, Past issues / 2 February 2006 / Quan Du, Institute of Molecular Medicine, Peking University, Meihong Chen, Chinese Human Genome Center Beijing, Claes Wahlestedt, Scripps Florida and Zicai Liang, Karolinska Institute

Although synthetic siRNA libraries are becoming more available, most high throughput siRNA library-based screening was carried out with siRNA libraries encoded by different vectors. In this article, siRNA library construction methods and HTS applications are summarised.

Applications in target ID and validation

Issue 4 2005, Past issues / 11 November 2005 / Oliver C. Steinbach, Head of Department, Technology Management, ALTANA Pharma AG

RNAi technology provides the ‘loss of function’ approach, which has been widely used in the last couple of years for analysis of gene function, and in drug discovery for identification and validation of potential drug target candidates. This technology is now widely applied for functional screens in order to identify disease associated signals and targets whose specific inhibition could potentially result in a curative effect for treatment of complex human diseases. The focus of such screens is evolving more towards druggable gene families rather than genome wide approaches – the latter being expensive, complex and sometimes confusing.

The promise and pitfalls

Issue 3 2005, Past issues / 22 August 2005 / Craig S. Mickanin, Research Investigator and Mark A. Labow, Executive Director, Genomic and Proteomic Sciences, Novartis Institutes for BioMedical Research

Perhaps the most significant technological advancement in the study of gene function in the post-genome era has been the discovery that RNA interference (RNAi) can be exploited for depletion of endogenous mRNA in mammalian cells. As the pharmaceutical industry has fallen under intense pressure to both identify and validate high-quality drug targets, the lure of bona fide genome-wide functional analysis and target identification using small interfering RNA (siRNA) has fueled the interest in what can now be truly called ‘functional’ genomics.

Target validation

Issue 2 2005, Past issues / 20 May 2005 / Jeroen DeGroot, PhD; Anne-Marie Zuurmond, PhD, Daniel Eefting, MD; Ruud A Bank, PhD; and Paul Quax, PhD.; TNO Quality of Life, Business Unit Biomedical Research

All diseases have a genetic component, whether inherited or resulting from the body’s response to environmental stresses such as viruses, toxins or trauma. The successes of the human genome project have enabled researchers to pinpoint errors in genes that cause or contribute to disease.

Forging therapeutics from small interfering RNAs

Issue 1 2005, Past issues / 7 March 2005 / Olaf Heidenreich, Department of Molecular Biology, Interfaculty Institute for Cell Biology, Eberhard Karls University Tübingen

Small interfering RNAs are irreplaceable tools for the functional analysis of pathological gene products. Therapeutic siRNA development leads to new treatment strategies for gene products, where conventional small molecule approaches have failed.
