1/10/2005 Lexington, Kentucky Ohio State's James Cancer Hospital as reported by Lex18.com The next time you're in the grocery store, try to find fresh black raspberries. Even when they're in season they can be hard to find, which is too bad, because scientists say black raspberries may be a potent cancer fighter. So how can you get the benefits of the berries year-round? The answer might be in America's love of snacking. Researchers at Ohio State's James Cancer Hospital have already shown that black raspberries may help prevent colon and esophageal cancers. Now, their latest studies suggest the berries may help battle oral cancer as well. In lab tests, the berries reduced tumors in the mouth by 44 percent. But there's just one problem. "For us, we would need to eat about four cups of fresh black raspberries a day," said Chris Weghorst, PH. D, of the James Cancer Hospital. So, Weghorst set out to concentrate the benefits of the berries into something easy to eat. Something like cancer-fighting lozenges. Now, for the first time, researchers will test these lozenges on oral cancer patients. Doctors will take a sample of tissue from their tumors once, and then do it again after patients have consumed the lozenges for up to three weeks. "We could evaluate the expression patterns in those two pieces of tissue and identify genes that were specifically responding to a black raspberry treatment," Dr. Weghorst said. Chef Renee Bean likes that idea. She has had oral cancer, and [...]

1/10/2005 New York, New York Dr. Frank C P. Holstege Nature Genetics (Feb. 2005) as reported by Cancerpage.com The gene expression profile of metastatic head and neck cancer is distinct from that seen with forms that have not spread, a finding that could improve the treatment of this malignancy, Dutch researchers report. For certain cancers, such as head and neck squamous carcinomas (HNSCCs), early detection of metastases to nearby lymph nodes is critical for appropriate therapy, senior author Dr. Frank C P. Holstege, from University Medical Center Utrecht, and colleagues note. Unfortunately, these metastases are often difficult to detect, resulting in inappropriate treatment for many individuals. In the present study, reported in the February issue of Nature Genetics, Dr. Holstege's team describes the identification of gene expression profiles that correlate with HNSCC lymph node metastases. In a training set of 82 HNSCCs tumors, optimal prediction was achieved using the profiles of 102 genes. In a validation set, gene profiling correctly determined the metastatic state of 19 of 22 tumors analyzed. Further testing showing that genetic profiling outperformed clinical diagnosis. "It is highly plausible that expression profiling will, in the future, improve diagnosis and treatment of oral cavity and oropharynx squamous cell carcinomas, particularly by reducing adverse side effects related to overtreatment, but also by reducing the severe risk of fatalities due to overlooked metastases in the case of 'watch and wait' strategies," the authors conclude.

1/10/2005 Providence, Rhode Island Felice J. Freyer The Providence Journal The practitioner claims the title of doctor on his Web site along with a medical degree under a charter from the governments of Liberia and Ghana. Federal agents yesterday raided the office of John E. Curran, a practitioner of "natural healing" who does not have a medical license, after the state medical board received a complaint that Curran was "posing as a doctor." Jason Simonian, a special agent of the U.S. Food and Drug Administration's office of criminal investigations, who was among those conducting the raid, said that the Internal Revenue Service and the U.S. Postal Service were also involved in the investigation. But Simonian declined to answer questions about what the agents were looking for. Thomas Connell, spokesman for U.S. Attorney Robert Clark Corrente, said: "I am not in a position to explain why they were there. There is no documentation that is on the public record. There were agents of the Food and Drug Administration and the Internal Revenue Service participating in a law-enforcement initiative." Yesterday, about a dozen agents were searching the office, on the third floor of One Richmond Square, and loading boxes full of bottles and canisters, along with some equipment, into a van. One batch of canisters contained "chocolate almond protein supplement" and another was labeled "BeneFin," with Curran's name printed on the label. Curran's lawyer, Artin H. Coloian, said, "A lot of this stuff is vitamin C. . . . regular stuff, ginger, [...]

1/8/2005 Pittsburgh Jennifer Bails Science Magazine as reported by Pittsburgh Tribune-Review A team of University of Pittsburgh researchers has discovered that too much of a single protein can cause a cascade of calamitous changes in a cell leading to the formation of cancerous tumors. The findings published in today's issue of Science, a prestigious peer-review journal, could help scientists develop cancer treatments that are safer and more effective than chemotherapy, said Susanne Gollin, one of the paper's authors. "The more we understand about tumor cells and how they misbehave compared to normal cells, the more we can target our research to developing potential cancer therapies," said Gollin, a human geneticist at Pitt's Graduate School of Public Health. Gollin collaborated with Pitt biologists Nicholas Quintyne and William Saunders. They found that too much of a protein called nuclear mitotic assembly protein -- or NuMA -- disrupts cell division by interfering with a second protein called dyenin. Large amounts of dyenin help make up the mitotic spindle, an assembly of fibers and proteins used to ensure that new cells are allotted the proper number of chromosomes. Before a healthy cell divides, it duplicates its chromosomes. These chromosomes are then evenly separated by the spindle so the two new cells have equal amounts of genetic material. Normal cells have mitotic spindles with two ends, or poles, with structures at either end called centrosomes that help direct cell division. But cancer cells often have extra centrosomes, which can lead to defective spindles with too [...]

1/6/2005 Louise Fong et al. Journal of the National Cancer Institute (vol 97, no 1, pp40-50) The mineral zinc may help prevent oesophageal and oral cancers in people at high risk, suggests research on rats. A team from the Kimmel Cancer Center of Thomas Jefferson University in Philadelphia found that rats that are deficient in dietary zinc experience increased expression of COX-2 in the oesophagus and tongue, an effect that is accompanied by a hyperplastic phenotype in these areas that is likely relevant to cancer development. Oesophageal and tongue cancers have previously been associated with dietary zinc deficiency, and these cancers often overexpress COX-2, a characteristic known to contribute to carcinogenesis. Louise Fong and colleagues report in today’s issue of the Journal of the National Cancer Institute (vol 97, no 1, pp40-50) that COX-2 overexpression accompanies hyperplasia in zinc-deficient rats. Treating the rats with zinc or a COX-2 inhibitor reduced COX-2 overexpression and reversed the hyperplasia found in the oesophagus.

1/6/2005 Reuben Lotan Journal of the National Cancer Institute, Vol. 97, No. 1, 3-4, January 5, 2005 Retinol (the prototypic vitamin A) and its metabolites called retinoids play important physiologic roles in embryonal development, vision, maintenance of epithelial differentiation, immune functions, and reproduction (1). Many of these functions are mediated by retinol metabolites such as all-trans-retinoic acid (ATRA) (2). ATRA modulates gene expression by means of nuclear receptors that are members of the steroid hormone gene superfamily. These receptors, retinoic acid receptors (RARs) and retinoid X receptors (RXRs), appear in at least three subtypes, designated alpha, beta, and delta. The receptors function as ligand-activated heterodimeric DNA-binding transcription enhancing factors and regulate the transcription of various genes, which play important roles during development and in adult tissues. Abberant expression and function of specific retinoid receptors, primarily RAR, have been associated with cancer development and progression (3,4). However, recent studies have highlighted additional mechanisms for abrogation of retinoid signaling in carcinogenesis. These involve abnormalities located upstream of retinoic acid and its nuclear receptors. These defects interfere with retinol storage and its metabolism to retinoic acid and result in a localized retinoid deficiency. Interestingly, we have suggested that decreased levels of RAR may be, at least in part, caused by local vitamin A deficiency (5). Dietary retinol is stored in the liver in specialized cells and delivered to various target tissues via a retinol-binding protein (6). However, retinol is also stored in various extra-hepatic tissues including breast epithelial cells. Retinyl esters are the [...]

1/6/2005 Lexington, KY staff Lexington NBC Affiliate (lex18.com) If you made a New Year's resolution to stop smoking or lose weight this year, you're not alone. Those are two of the most popular resolutions, and may have benefits that never occurred to you. Both of them can help cut your risk of cancer, but they're not the only ones. Here are the top five cancer-curbing resolutions for 2005. If you vow to quit smoking this year, you'll be doing your body a huge favor. It's the number one way to cut your risk for cancer, and we're not just talking about lung cancer. "Bladder cancer, cervical cancer, colon cancer, throat cancer, mouth cancer -- they're all associated with cigarette smoking," said Electra Paskett, Ph.D., of Ohio State University's James Cancer Hospital. Exercise is another way to cut your cancer risk. Vigorous exercise can reduce your risk of colorectal cancer by up to 50 percent, and breast cancer by as much as 30 percent. It's a resolution with profound personal meaning for Jessica Bayles. "After my mother passed away of cancer, from then on I knew. From this point on I have to get serious about it. I have to make sure I exercise, have to make sure I eat right," said Bayles. Which brings us to number three in our top five -- eating right, including four to six helping of fruits and vegetables a day. "If we all did that, we could expect there to be a 20 to [...]

1/5/2005 Jacksonville, FL Kerry Sullivan - editor First Coast News Whether you are wearing one because it looks cool, or because you have been touched by someone with cancer, wristbands, like the yellow "Livestrong" bracelet by Lance Armstrong are becoming more popular than ever on the first coast. From the Avenues Mall to the soccer fields at Jacksonville University, everyone is wearing them. For Freshman Courtney Eppleman, her "Livestrong" wristband is in honor of her grandfather who died of throat cancer last year. "If I can save one life by wearing it, then I feel good," says Eppleman. Eppleman is one of dozens of ladies on the team who wears her wristband proudly. Their coach, Chris Kouns, got them started with a kickout cancer match when he took the head coaching job last year. They haven't taken them off since. "My father is a cancer survivor so it meant a lot to me to do this. They had a kickout cancer match up north where I came from, but not down here," Kouns says. While the yellow "Livestrong" wristbands seem to be the most popular, another color is getting all the attention on the first coast. "I don't take mine off," Patty Gruelle says. Gruelle is a breast cancer survivor two times around. The "Livestrong" wristband was the inspiration behind her latest project, pink "Carpe Diem" breast cancer wristbands. Gruelle teamed up with the Donna Hicken foundation to seize the day and support the disease. She says it's so important [...]
