UCLA researchers find link between intestinal bacteria and white blood cell cancer

Posted: Published on July 17th, 2013

Public release date: 16-Jul-2013 [ | E-mail | Share ] Contact: Shaun Mason smason@mednet.ucla.edu 310-206-2805 University of California - Los Angeles Researchers from UCLA's Jonsson Comprehensive Cancer Center have discovered that specific types of bacteria that live in the gut are major contributors to lymphoma, a cancer of the white blood cells. Published online ahead of press today in the journal Cancer Research, the study was led by Robert Schiestl, member of the Jonsson Cancer Center and professor of pathology and laboratory medicine, environmental health sciences, and radiation oncology. In rodents, intestinal bacteria influence obesity, intestinal inflammation and certain types of epithelial cancers. (Epithelial cancers affect the coverings of the stomach, liver or colon.) However, little is known about the identity of the bacterial species that promote the growth of, or protect the body from, cancer or about their effect on lymphoma. Up to 1,000 different species of bacteria (intestinal microbiota) live in the human gut. Intestinal microbiota number 100 trillion cells; over 90 percent of the cells in the body are bacteria. The composition of each person's microbiome the body's bacterial make-up is very different, due to the types of bacteria people ingest early in their lives, as well … Continue reading →

Stem Cell Meeting on the Mesa approaches

Posted: Published on July 17th, 2013

LA JOLLA The 2013 Stem Cell Meeting on the Mesa, San Diego's biggest meeting of stem cell science and business, takes place Oct. 14-16 in La Jolla. This symposium has grown over the years from a strictly scientific event to a major nexus of biotech science and business in regenerative medicine. It's sponsored by the Alliance for Regenerative Medicine, the California Institute for Regenerative Medicine and the Sanford Consortium for Regenerative Medicine. The meeting begins Oct. 14-15 with the business part, the third annual Regenerative Medicine Partnering Forum. Held at the Estancia La Jolla Hotel & Spa, this event is for business executives to discuss advances in regenerative medicine from a business perspective. On Oct. 16, the scene moves over to the Salk Institute for the eight annual Scientific Symposium. Here, scientists, business leaders, patient advocates and government officials will discuss the state of regenerative medicine from their perspectives. A preliminary agenda is available now; sponsors say a full agenda will be posted soon. And for more context about the meeting and its history, here's headlines and links to stories about the meeting in previous years: 2012 - Stem cell meeting takes on national, international flavor 2012 - Venter: Biofuels … Continue reading →

Viewpoints: Risks are many in paying women to donate eggs

Posted: Published on July 17th, 2013

As scientists in California delve more deeply into stem cell research and reproductive science, it is essential that women donating their eggs for research not be exploited or put at risk. A bill on the governor's desk would do just that. On July 1, the state Senate passed AB 926, a bill sponsored by the American Society for Reproductive Medicine that "will reverse the current ban on compensation for women providing human oocytes (eggs) for research." That ban was passed almost unanimously in 2006; Sacramento got it right the first time. The new bill purports to "promote equity" for women as "research subjects." Since men can be paid for sperm to be used either for research or for assisted reproduction, supporters of AB 926 argue that prohibiting women from selling eggs for research is "unfair." The comparison is ludicrous. A sperm donor is screened for psychological and medical disorders. Once accepted, he may visit the sperm bank regularly. In some repositories he is provided a bed to relax on, erotic videos and magazines. While sperm donors are asked to abstain from sexual activities for two to five days before making a donation, the process is risk-free. Egg donation is invasive. … Continue reading →

Scientist to California: Fund research like a nation

Posted: Published on July 17th, 2013

LA JOLLA California's boosters like to compare its economic statistics to other nations. The message is that California's economy is more like a nation than a state. Larry Goldstein, director of UCSD's stem cell program, said California should apply that logic to funding of science and technology research. Since the federal government is cutting back, it's time for California to pick up the slack, Goldstein said at Monday's "Pipeline for Life" symposium. The event was held by the California Healthcare Institute Foundation at the Salk Institute, in San Diego's bioscience research hub of Torrey Pines Mesa. Larry Goldstein lays out the case for California funding its own sci-tech research, giving San Diego as an example of what can happen. I've embedded a short video clip above of Goldstein making his point, part of a much longer speech he gave outlining issues and opportunities in stem cell research. If you don't want to watch the video, the text of his remarks about California funding research are below. It's very slightly edited for clarity. * * * * * * "The population of California is 10 percent of the United States, we consume about 10 percent of the funding for research, but … Continue reading →

Even healthy-looking smokers have early cell damage which destroys necessary genetic programming

Posted: Published on July 17th, 2013

Public release date: 16-Jul-2013 [ | E-mail | Share ] Contact: John Rodgers pr@med.cornell.edu 646-317-7401 Weill Cornell Medical College NEW YORK (July 16, 2013) -- Smokers who've received a clean bill of health from their doctor may believe cigarettes haven't harmed their lungs. However, researchers at Weill Cornell Medical College have found that even smokers who seem healthy have damaged airway cells, with characteristics similar to cells found in aggressive lung cancer. The study, published today in the journal Stem Cell, compared cells that line the airway from healthy nonsmokers with those from smokers with no detectable lung disease. The smokers' cells showed early signs of impairment, similar to that found in lung cancer -- providing evidence that smoking causes harm, even when there is no clinical evidence that anything is wrong. "The study doesn't say these people have cancer, but that the cells are already starting to lose control and become disordered," says the study's senior investigator, Dr. Ronald G. Crystal, chairman and professor of genetic medicine at Weill Cornell Medical College. "The smoker thinks they are normal, and their doctor's exam is normal, but we know at the biologic level that all cigarette smokers' lungs are abnormal to … Continue reading →

How patients experience direct-to-consumer genetic testing

Posted: Published on July 17th, 2013

July 16, 2013 Several companies sell genetic testing directly to consumers, but little research has been done on how consumers experience such tests. The tests have raised questions about the validity and accuracy of the information provided to consumers -- especially without the involvement of a qualified health care professional. Now, a study lead by a Loyola University Chicago Stritch School of Medicine researcher is providing insight into how a diverse sample of primary care patients experience genetic testing. Lead researcher Katherine Wasson, PhD, MPH, and colleagues conducted in-depth interviews with 20 patients recruited from primary care clinics. Among the findings, published online ahead of print in the Journal of Community Genetics: - Most participants thought results were fairly easy to understand -- with the help of a genetic counselor (provided by the study, not the testing company). But fewer than half said they might be able to understand results on their own. - Most participants expressed no concern or hesitation about testing. But a few worried about confidentiality -- especially whether results could affect their health insurance coverage. A few also expressed fears about getting bad results. As one participant explained, "I mean, you want to know, but then … Continue reading →

Highest risk Alzheimer's genetic carriers take positive steps after learning risk status

Posted: Published on July 17th, 2013

Public release date: 16-Jul-2013 [ | E-mail | Share ] Contact: Kim Menard kim.menard@uphs.upenn.edu 215-662-6183 University of Pennsylvania School of Medicine BOSTON - People who found out they carried an uncommon genetic risk for Alzheimer's disease did not experience more anxiety, depression or distress than non-carriers, and were more active in efforts to reduce their risk of Alzheimer's disease - by exercising, eating a healthy diet and taking recommended vitamins and medications - report researchers from the Perelman School of Medicine at the University of Pennsylvania today at the 2013 Alzheimer's Association International Conference (AAIC). Researchers note that this study will inform how research studies and clinical practices reveal genetic and other risk factors to people interested in being tested in the future. "This study informs our understanding of the impact of people finding out their genetic risk for Alzheimer's in the absence of any treatments to prevent dementia," said lead study author Jason Karlawish, MD, professor of Medicine and Medical Ethics and Health Policy in Penn's Perelman School of Medicine. "We saw that, following their genetic counseling session, people took positive steps to mitigate their Alzheimer's risk, such as following a healthy diet and exercising. They might also be … Continue reading →
