Novel analysis method organizes genomic cancer data

2011-07-01
(Press-News.org) The technology that allows scientists to profile the entire genome of individual tumors offers new hope for discovering ways to select the best treatment for each patient's particular type of cancer. However, these profiles produce huge amounts of data, and the volume alone creates unique analytical problems.

In a study published on-line this week in the journal BMC Medical Genomics, researchers from Huntsman Cancer Institute (HCI) at the University of Utah describe a new analytical approach based on a concept called multiplicity, that can organize large amounts of varied genetic data. The method allows researchers to create three-dimensional models revealing previously unknown relationships among the genes involved with different types of cancer.

"This technique shows similar genetic profiles for different types of cancers, which could open the door to trials of already approved drugs for additional cancers," said Lewis Frey, PhD, assistant professor in the Department of Biomedical Informatics and an HCI investigator. "It can bring to light previously unknown genetic connections between different cancers, helping focus the search for cancer-causing genetic mutations. It makes whole genome data more usable for both clinical and laboratory researchers."

Stephen R. Piccolo, Ph.D., a postdoctoral research associate in the Department of Biomedical Informatics at the University of Utah, and Mary E. Edgerton, M.D., Ph.D., associate professor in the Department of Pathology at MD Anderson Cancer Center in Houston, Texas, are co-authors of the article. The study was funded in part by an Incentive Seed Grant from the University of Utah, and a National Library of Medicine training grant.

###

The mission of Huntsman Cancer Institute (HCI) at The University of Utah is to understand cancer from its beginnings, to use that knowledge in the creation and improvement of cancer treatments, to relieve the suffering of cancer patients, and to provide education about cancer risk, prevention, and care. HCI is a National Cancer Institute-designated cancer center, which means that it meets the highest national standards for cancer care and research and receives support for its scientific endeavors. HCI is also a member of the National Comprehensive Cancer Network (NCCN), a not-for-profit alliance of the world's leading cancer centers that is dedicated to improving the quality and effectiveness of care provided to patients with cancer.

Telomeres: 2 genes linked to why they stretch in cancer cells

Telomeres: 2 genes linked to why they stretch in cancer cells
2011-07-01
Scientists at Johns Hopkins have provided more clues to one of the least understood phenomena in some cancers: why the "ends caps" of cellular DNA, called telomeres, lengthen instead of shorten. In a study published online June 30 in Science Express, the Johns Hopkins researchers say they have identified two genes that, when defective, may cause these telomere elongations. Telomeres contain repeated sequences of DNA that, in normal cells, shorten each time a cell divides. Without telomeres, the cell division-related shortening could snip off a cell's genes and disrupt ...

Your Nose: Form and Function

2011-07-01
Your nose does more than just sit in the middle of your face and present a good metaphor for everything obvious. Your nose is essential to breathing, smelling, and protecting your body from dehydration and infection. Nasal Breathing Nasal breathing should be the normal method. Mouth breathing is reserved for when you're running for your life or trying to make a creepy phone call. Nasal breathing performs a number of important functions: - Conditioning the air: Your nose warms incoming air and adds humidity to protect your throat and lungs - Filtering the air: ...

The Role of a Plastic Surgeon in Your Mastectomy

2011-07-01
Adjusting to the loss of a breast or to a different breast shape following a mastectomy can be traumatic. A mastectomy may save your life, but it can also leave you feeling self-conscious about your appearance. In considering a mastectomy, one important decision is whether you will want to undergo breast reconstruction at the time of your mastectomy. A consultation with a breast reconstruction surgeon prior to scheduling your mastectomy can help you determine whether you're a good candidate for breast reconstruction surgery and review your breast reconstruction options. Mastectomy ...

'Zombie' stars key to measuring dark energy

Zombie stars key to measuring dark energy
2011-07-01
(Santa Barbara, Calif.) –– "Zombie" stars that explode like bombs as they die, only to revive by sucking matter out of other stars. According to an astrophysicist at UC Santa Barbara, this isn't the plot for the latest 3D blockbuster movie. Instead, it's something that happens every day in the universe –– something that can be used to measure dark energy. This special category of stars, known as Type Ia supernovae, help to probe the mystery of dark energy, which scientists believe is related to the expansion of the universe. Andy Howell, adjunct professor of physics ...

Why do we share stories, news and information with others?

2011-07-01
People often share stories, news, and information with the people around them. We forward online articles to our friends, share stories with our co-workers at the water cooler, and pass along rumors to our neighbors. Such social transmission has been going on for thousands of years, and the advent of social technologies like texting, Facebook, and other social media sites has only made it faster and easier to share content with others. But why is certain content shared more than others and what drives people to share? Well, according to Jonah Berger, the author of a new ...

Red wine: Exercise in a bottle?

2011-07-01
Bethesda, MD—As strange as it sounds, a new research study published in the FASEB Journal (http://www.fasebj.org), suggests that the "healthy" ingredient in red wine, resveratrol, may prevent the negative effects that spaceflight and sedentary lifestyles have on people. The report describes experiments in rats that simulated the weightlessness of spaceflight, during which the group fed resveratrol did not develop insulin resistance or a loss of bone mineral density, as did those who were not fed resveratrol. According to Gerald Weissmann, M.D., Editor-in-Chief of the ...

Fireworks Safety Tips: Don't Blow Off Your Hand - 10 Ways to Stay Safe With Fireworks

2011-07-01
With July 4 fast approaching, MSNBC reports that heavy drought and wildfires burning in parts of Florida have caused many affected counties and cities to ban the use of fireworks. Florida Division of Forestry Annaleasa Winter says, "It only takes one spark to ignite a blazing wildfire that could threaten your home and, possibly, your whole neighborhood. The risk is just too great," as News 4 Jax reports regarding similar drought and wildfires last year in Florida. 2011 is no different. But, like every July 4 holiday, you're going to get together with ...

CSHL team identifies enzyme that is an important regulator of aggressive breast cancer development

2011-07-01
Cold Spring Harbor, NY – Researchers at Cold Spring Harbor Laboratory (CSHL) have identified an enzyme that appears to be a significant regulator of breast cancer development. Called PTPN23, the enzyme is a member of a family called protein tyrosine phosphatases, or PTPs, that plays a fundamental role in switching cell signaling on and off. When the scientists suppressed the expression of PTPN23 in human mammary cells, they noted a cascade of effects that included the cells breaking away from their anchors; their scattering; and their invasion through extracellular ...
