deCODE and Radboud University Discover Common Variants in the Human Genome Conferring Risk of Bladder Cancer

Detection may be used to complement and target screening for the disease; findings will be integrated into the deCODEme(TM) personal genome scan.

REYKJAVIK, Iceland, Sept 14, 2008

DCGN and colleagues at Radboud University Medical Center in the Netherlands today report the discovery of two common single-letter variants in the human genome (SNPs) that confer increased risk of urinary bladder cancer. Approximately 20% of people of European descent carry two copies of the first variant, a version of a SNP on chromosome 8q24, putting them at a 50% higher risk of developing bladder cancer than those without the variant. Individuals who carry two copies of a common version of another SNP on chromosome 3 were found to be at a 40% higher risk of the disease than non-carriers. These are the best-replicated genetic variants ever linked to bladder cancer risk, and the study analyzed genotypic data from more than 40,000 patients and controls from Iceland, the Netherlands and eight other European countries. The paper, entitled ‘Sequence variant on 8q24 confers susceptibility to urinary bladder cancer,’ will appear today in the online edition of Nature Genetics at www.nature.com/ng.
“In all cancers, the ability to identify individuals at high risk, screening them intensively and intervening early, is the key to improving prevention and outcomes. We expect that the detection of these and other risk variants will soon be employed to complement the assessment of standard risk factors for bladder cancer. As with all of our discovery work, we seek to publish our findings and establish a solid intellectual property position in order to bring these swiftly into the healthcare arena, and have already folded today’s findings into our deCODEme(TM) personal genome analysis service. At the same time, we are working to identify the common thread of variants we and others have discovered on chromosome 8q24 that confer risk of several forms of cancer, including prostate, breast, colorectal and now bladder. If a common molecular mechanism exists, it could provide an important insight into oncogenesis more broadly,” said Kari Stefansson, CEO of deCODE.
For a more detailed discussion of today’s findings you can watch a video discussion between Dr. Stefansson and Dr. Simon Stacey on our blog, at www.decodeyou.com.
Urinary bladder cancer is the sixth most common type of cancer in the United States. It is estimated that 68,810 individuals will be diagnosed with bladder cancer in the United States during 2008 and that 14,100 people will die of the disease. Bladder cancer has been linked to exposure to various types of toxic substances such as cigarette smoke and industrial chemicals. Although it has been known for some time that genetic factors also play a significant role, identifying validated genetic risk variants had been problematic. Incidence of bladder cancer varies considerably between ethnicities, and as the risk factors reported here were discovered by analyzing DNA from groups of European descent, it is our hope that the publication of these findings will contribute to the swift analysis of the impact of these variants in cohorts of other continental ancestries.
The authors wish to thank the thousands of patients and control subjects who participated in this study, and acknowledge the assistance of national cancer registries that worked to identify potential participants. Data and sample collection in Iceland and the Netherlands was funded in part by European commission grants LSHC-CT-2005-018827 and LSHM-CT-2004-005166.

Colon Cancer Oncogene Discovered

SUNDAY, Sept. 14 (HealthDay News) — Researchers have identified a new genetic player in the development of colon cancer.

The findings implicate CDK8, a protein that regulates gene expression in the proliferation of colorectal cancer, the researchers found.

Should the results be validated, they could lead to new therapeutic approaches for colon cancer, as well as new screening and chemopreventative strategies, said Dr. Durado Brooks, director of prostate and colorectal cancer at the American Cancer Society.

“I think it is important work,” Brooks said. “They have identified what apparently is an oncogene associated with some colorectal cancers.”

Dr. William Hahn, of the Dana-Farber Cancer Institute in Boston, and his colleagues screened human colon cancer cells for genes that met three criteria: They were required for cellular proliferation, critical to regulating the WNT/beta-catenin signaling pathway known to be involved in the bulk of colon cancer cases, and also genetically amplified in cancerous cells.

“When we did that, we found one gene that fulfilled all three criteria, and that is CDK8,” Hahn said.

The results were published in the Sept. 14 issue of Nature.

CDK8 is a member of the so-called mediator complex, which bridges distant protein complexes to activate expression of certain genes.

According to Hahn, the study has two take-home messages.

The first, he said, is the apparent prevalence of colorectal tumors with elevated CDK8. Of the 50 tumors that Hahn and his team analyzed, 31 (62 percent) displayed evidence of CDK8 gene amplification — that is, the tumors contained more than the normal two copies of the gene, which usually leads to higher levels of protein expression.

“This is surprising in the sense that it occurs in a large percentage of colon cancers, and we didn’t know about it,” he said.

The second message involves the potential pharmacologic benefits of these results. CDK8 is a type of protein known as a kinase. Kinases are enzymes that catalyze the transfer of phosphate groups from one molecule to another. That action is like flipping a molecular switch, causing the recipient protein to turn on or off. It turns out that kinases tend to play key roles in the biochemical pathways that often go haywire in cancer, so they are popular targets for drug developers.

“There’s a reasonable likelihood, though it hasn’t happened yet, that one could develop a drug that targets this protein in colon cancer,” he said, “and you could determine which colon cancer patients are likely to benefit.”

That’s because Hahn and his team showed, using a genetic technique called RNA interference, that knocking down CDK8 protein levels in cancer cells that normally contain elevated CDK8 levels, reduced cell proliferation. That effect was less pronounced in cells containing lower levels of CDK8.

So, those tumors with elevated CDK8 levels might make good candidates for novel drug therapies directed at the enzyme, Hahn said.

“This fits into an emerging concept in cancer treatment,” he explained. “Not only do we develop better therapies, but hand-in-hand, we want to find which patients will respond to therapy, rather than giving it to everyone and hoping they will respond.”

Brooks agreed that CDK8 is a potential drug target. He noted other potential benefits, too, such as possibly being able to identify those at elevated risk of developing colorectal cancer, or identifying those who should be screened earlier and more comprehensively. It may even be possible to develop chemopreventative compounds that could diminish the risk of developing cancer in the first place.

“But we are at the very beginning of that pathway,” Brooks added. “All they have shown is this oncogene seems to be associated with a significant number of cancer specimens…. But translating that to, number one, how broadly this occurs in the broader community of colorectal cancer, and also in the general patient population, and then next, how can we use this information, we are at the very beginning of that process.”

In another report in this week’s online issue of Nature Genetics, researchers from Iceland said that they have found a genetic variant associated with increased risk of urinary bladder cancer.

First of 100 Arab Human Genomes Sequenced by Saudi Biosciences, Beijing Genomics Institute Shenzhen, and CLC bio

Riyadh, Kingdom of Saudi Arabia — September 9, 2008 — An international consortium consisting of Saudi Biosciences, Beijing Genomics Institute Shenzhen, and CLC bio have in a joint effort performed an initial sequencing and analysis of the first Arab human genome, as part of a large project to sequence 100 Arab human genomes to map the unique genetic variations of the Arab population.

His Royal Highness Prince Ahmad bin Sultan bin Abdulaziz, Head of the Board of Directors at Saudi Biosciences, said “This marks the first milestone in our goal to pioneer the personalized medicine era in the Arab world, and the next step is to lead a large project to sequence 100 Arab genomes at high resolution no later than the end of 2010. Our ambitions are to make this project go beyond similar international efforts, both in terms of quality and quantity!”

Dr. Saeed Hussain from Saudi Bio Sciences, states, “We are extremely proud to present the first Arab human genome! This project launches the Kingdom of Saudi Arabia in to the small circle of nations who are currently in the process of building sophisticated databases of human genetic variation. This database is fundamental in the process of analyzing and understanding the specific genetic makeup of Arabs, which in turn will provide key knowledge to improve medical care for this large group of people.”

How was the project realized?
After Saudi Biosciences launched this project early 2008, an international joint collaboration with  Beijing Genomics Institute and CLC bio was organized.  A high quality sequencing of this genome was generated using Illumina’s Genome Analyzer platform. Afterwards the data was assembled and analyzed using CLC bio’s CLC Genomics Workbench.

“The fact that Saudi Biosciences have selected CLC bio among all the potential software providers, emphasizes that we are the world’s leading provider of genomics software solutions. We could think of no better opportunity to refine our software solutions, than a project like this, which is truly at the forefront of genomics research. This is indeed a unique and visionary project that we are excited and proud to be a part of.” said the Director of Scientific Solutions at CLC bio, Dr. Roald Forsberg.

The results, including analysis and identification of the unique variants of the Arab genome compared to African, European and Asian genomes, have been accumulated. The data are currently confidential but will be released following publication.

What is the impact of this project?
One of the most important goals of modern medicine and genetic research is the goal of tailoring medical care to an individual’s needs, based on information from the individual’s genotype or gene expression profile, so-called personalized medicine. Personalized medicine can offer huge advances in medical care but can only succeed if the genetic variation of humans can be accurately mapped.

The advent of a new generation of experimental techniques, has now given biomedical researchers the opportunity to map the complete genetic variation of large numbers of humans via full genome sequencing. The data produced from such efforts will provide an unparalleled amount of information that can be used to distinguish the unique groups within the human race, and help tailor medical care that targets the specific needs of different populations and individuals. Personalized medicine is thus on the brink of a major breakthrough.

However, the projects scheduled so far have aimed at characterizing mainly three populations - Africans, Europeans and Asians. This means that an accurate characterization and discovery of genetic variation in the Arab people can not be immediately expected and that the Arab populations may receive less of the benefits that will follow the advancement of personalized medicine.

This is why the Kingdom of Saudi Arabia wanted to start building an Arab human genomics database now, in order to scientifically explore the unique genetic composition in the Arab world. The database is fundamental in the process of analyzing and recognizing the distinct genetic makeup of Arabs, which in turn can provide knowledge to help stratify disease status, select between different medications and tailor their dosage, provide a specific therapy for an individual’s disease, or initiate a preventative measure that is particularly suited to that patient at the time of administration.

His Royal Highness Prince Ahmad bin Sultan bin Abdulaziz, Head of the Board of Directors at Saudi Biosciences, said “The Arab world was never an active participant in the large international projects in the field of genomics, and we believe that this should change. Working with an international collaborator such as Beijing Genomics Institute, an advanced institute in genomics studies, and CLC bio, the leaders in bioinformatics solutions with their recently released CLC Genomics workbench, we plan to participate actively in international efforts towards understanding the genomics basis of human diseases.”

BIO-Europe 2008: The World’s Leading Biotech Companies and Deal-Makers Get Ready for Three Days of Intense Partnering in Mannheim/Heidelberg

Filed under: Europe, Press Releases, Biotech & Pharma Law — admin @ 4:04 pm

CARLSBAD, Calif. & WASHINGTON — September 2, 2008 — The leaders of the biotechnology industry will once again gather for BIO-Europe, the world’s largest stand-alone partnering conference, in Mannheim/Heidelberg, Germany, November 17-19. With biotech deal-making still the thrill in drug development markets, this year’s BIO-Europe promises to set new standards for generating quality partnering meetings and providing the information required to successfully navigate opportunities in an era of significant biotech industry change. Many of the most respected industry thought leaders and decision makers will come to the Rhein-Neckar biotech super cluster to examine the issues, new business approaches, policy trends that are vital to biotech’s successful long-term future.

A central theme to BIO-Europe 2008 is partnering in a globalizing biotechnology market, featuring interactive workshops led by renowned industry experts on important emerging topics such as understanding the critical issues upon entering the U.S. market and partnering with U.S. companies; deal-making in China; deal-making with Japanese companies; and how to adjust to changes in U.S. patent law.

Other conference highlights include the not-to-be-missed 6th annual “A Day in the Life of Experienced Deal-makers” plenary session. Led by James Watson, Managing Director and Head of Merchant Banking, Burrill & Company and including industry notables such as Andrew Gengos, Vice President, Strategy and Corporate Development, Amgen; Mark McDade, Executive Vice President, UCB Pharma; Dr. Simon Moroney, Chief Executive Officer, Morphosys; John Goddard, Senior Vice President and Global Head of Strategic Planning and Business Development, AstraZeneca; Simon Turton, Managing Director, Warburg Pincus; and William Ringo, Senior Vice President, Strategy and Business Development, Pfizer; this highly popular and provocative forum promises to continue its tradition of lively and insightful debate over key issues of strategic deal-making by some of the biggest names in biotech partnering.

One of the more difficult tasks for the biopharmaceutical industry is to explain the value of new drugs to the wide variety of constituencies with which they interact, all of whom have a vested interest in minimizing the value of new drugs to the system. Successfully demonstrating value is critical if the industry is to obtain adequate reimbursement for its products, yet the environment in which the industry operates continues to put up more hurdles. In “Demonstrating the Value of New Drugs”, Dr. Karen Bernstein, Chairman and Editor in Chief, BioCentury Publications will lead a panel exploring how companies can best navigate emerging challenges such as a FDA that increasingly emphasizes safety in response to political pressures; a growing emphasis on comparative efficacy and comparative effectiveness; and the possibility of a new U.S. president less friendly to the industry.

Notes to Editors:
Entry to BIO-Europe 2008 is free to the media, including full access to the partnering system, sessions, press conferences, workshops, and pre-arranged partnering meetings.

New drug slows down cancer

Filed under: North America, Cancer Research, Press Releases — Fred @ 11:44 am

WA researchers have taken the first step towards developing new anti-cancer medications that could activate a gene shown to block the growth of cancerous cells.

Led by Western Australian Institute for Medical Research (WAIMR) Director Professor Peter Klinken, the scientists have screened a large collection of drug-like molecules and recently identified a number of compounds which can increase levels of the Hls5 gene.

“This discovery is very encouraging and a great step forward in our quest to create new cancer treatments,” said Professor Klinken.

“Because of the role Hls5 plays in keeping cell growth at a normal rate, we expect that these compounds will greatly slow down the growth of cancer cells.”

The Hls5 tumour suppressor gene was reported by Professor Klinken’s team in 2004.

The group’s research has revealed that people who don’t have the gene - or those who have a mutated or inactive form of the gene - are more likely to develop certain types of cancer.

In conjunction with WA-based biotechnology company BioPharmica, the WAIMR team has spent more than a year screening 70,000 compounds which increase Hls5 levels.

“Our preliminary data reveals that several of these compounds do indeed markedly slow down the growth of human cancer cells,” said Professor Klinken.

“Importantly, we also know through computer modeling that nearly all of these compounds have drug-like qualities.”

“From here, we take the research to the next phase of laboratory testing with the ultimate hope of investigating if one of these molecules can be used to create a fresh treatment that can slow growth of cancer cells in patients.”
