Abnormal cell division explained

Why do some cancer cells divide not into two, as cells are supposed to do in mitosis, but into three-four new cells that look thoroughly abnormal? This question was raised as early as the 1890s by the German tumor researcher David Hansemann, who could observe the strange mitosis even using the microscopes of his day. Now another David, Lund University researcher David Gisselsson, has found an answer.

National clinical trial examines new option for kidney cancer patients

The trial, which opened last September, offers research subjects who qualify a new, targeted therapy in addition to standard immune therapy. The drug combination is being studied in a national Phase II clinical trial led by OHSU Cancer Institute researcher Christopher Ryan, M.D., through the Southwest Oncology Group, one of the largest clinical trial cooperative groups in the United States.

Angiogenesis : Blocking tumor growth and treating infarction - a new target

Our tissues are able to form new blood vessels throughout life. This mechanism, which is called angiogenesis, is essential notably in the case of myocardial infarction, stroke and limb ischemia. The very same mechanism, however, keeps tumors supplied with nutrients and oxygen thus enabling them to continue growing.

Isotopes for society

The nucleus of an atom contains protons and neutrons. However, some atoms of the same chemical element can have varying numbers of neutrons, giving so-called isotopes of that element.

Hereditary colorectal cancer risk lowered in those without certain gene defect

Families with a certain type of hereditary colorectal cancer have a reduced cancer risk if they do not have a gene defect found in many with this type of cancer risk, according to a study in the April 27 issue of JAMA.

Use of positron emission tomography may eliminate more strenuous drug development trials with animals

A number of articles explore the use of positron emission tomography (PET) and small animal imaging—nonsurgical techniques that open the door to understanding and treating human diseases—in the April issue of the Society of Nuclear Medicine’s Journal of Nuclear Medicine.

Maxim Pharmaceuticals issued patent for method of identifying therapeutically effective immunosupressive agents

Maxim Pharmaceuticals have announced the United States Patent and Trademark Office issued U.S. patent number 6,828,091 B2, entitled "Method of Identifying Immunosuppressive Agents."

Scientists have, for the first time, induced a state of reversible metabolic hibernation in mice

Scientists at Fred Hutchinson Cancer Research Center have, for the first time, induced a state of reversible metabolic hibernation in mice. This achievement, the first demonstration of "hibernation on demand" in a mammal, ultimately could lead to new ways to treat cancer and prevent injury and death from insufficient blood supply to organs and tissues.

Nanoparticles reveal tiny cancerous tumors

Specially designed nanoparticles can reveal tiny cancerous tumors that are invisible by ordinary means of detection, according to a study by researchers at Washington University School of Medicine in St. Louis.

High levels of immunosuppressant may lead to tumor recurrence

A new study on the incidence of liver cancer after transplant found that high levels of the immunosuppressant cyclosporine favored tumor recurrence and identified blood levels of the drug that should not be exceeded. Lower levels of cyclosporine levels did not affect rejection rates.

Eating lots of fish during and after pregnancy reduces daughters' risk of developing breast cancer

Mothers who eat foods rich in omega-3 fatty acids during pregnancy and while nursing, and who continue to feed their babies such a diet after weaning, may reduce their daughters' risk of developing breast cancer later in life dramatically, according to research presented here today at the 96th Annual Meeting of the American Association for Cancer Research.

RNA interference permanently silences key breast cancer gene

In laboratory mouse experiments, researchers at The University of Texas M. D. Anderson Cancer Center have developed a way to use RNA interference (RNAi) so that it permanently hampers breast cancer development. The technique permanently silences activated STAT3, a crucial gene found in some human breast tumors, thus reducing the cancer's ability to become invasive.

New gene linked to familial cancer

Scientists have identified a new gene that appears to be linked to a small but significant percentage of familial cancer cases – as well as seemingly randomly occurring malignancies.

Selenium will have critical role in prostate cancer treatment

Researchers at Fox Chase Cancer Center in Philadelphia have come a step closer to understanding selenium's molecular role in causing prostate cancer cells to self-destruct. According to data presented today at the 96th Annual Meeting of the American Association for Cancer Research in Anaheim, Calif., selenium helps malignant cells overcome their resistance to TRAIL-induced apopstosis (self-inflicted cell death).

Breast cancer gene may play a major role in the recurrence of prostate cancer

A gene associated with breast cancer also may play a major role in the recurrence of prostate cancer, according to new research from the University of North Carolina at Chapel Hill School of Medicine and UNC Lineberger Comprehensive Cancer Center.

Researchers find ovarian cancer patients who appear to respond better than others to gefitinib, or Iressa

Researchers at Fox Chase Cancer Center in Philadelphia have identified a subset of ovarian cancer patients who appear to respond better than others to gefitinib, or Iressa. The research was presented today at the 96th Annual Meeting of the American Association for Cancer Research in Anaheim, Calif.

Combination chemotherapy shows small survival benefit in advanced stomach cancer

Patients with advanced stomach cancer have the best chance of prolonging their survival with a combination of chemotherapies instead of just one, according to a new review of previous studies.

Searching for the right pharmaceutical agent: survival as the indicator

Tumor cells divide fast. They thus require a high supply of components for their DNA, like purines. The biosynthesis of purines could now be a new point of attack for chemotherapy. However, without a natural model, the search for an inhibitor for a cellular process is like the proverbial search for a needle in a haystack. An American research team has developed a clever way to quickly conjure the desired "needle" out of the hay, presenting several candidates to act as starting points for the design of a purine synthesis inhibitor.

Researchers find promising cancer-fighting power of synthetic cell-signaling molecule

Novel anti-cancer compounds called Enigmols suppress the growth of human cell lines representing cancers of the prostate, breast, colon, ovary, pancreas, brain and blood, and reduce tumors in three animal studies, new research shows.

Ancient protein could be critical to stopping the uncontrolled division of tumor cells that cause cancer

Molecular Biology and Microbiology professor Mark Muller has found that the protein, called MKRN1, promotes the destruction of an enzyme called telomerase that enables rapid duplication of cells. While researchers have known for years that healthy cells repress telomerase, they haven't understood why.
