Circadian genes may be involved in bipolar disorder

Disrupt the gene that regulates the biological clocks in mice and they become manic, exhibiting behaviors similar to humans with bipolar disorder, UT Southwestern Medical Center researchers have found.

Inflammation plays key role in the metastasis of prostate cancer

Many would assume that "mounting an immune response" or "having your body fight the cancer" is a good thing.

Scientists decipher a signaling pathway crucially involved in Crohn's disease and ulcerative colitis

Inflammatory bowel diseases, such as Crohn's disease and Ulcerative Colitis, severely impair the lives of more than four million people worldwide. The development of effective therapies against these diseases requires an understanding of their underlying molecular mechanisms.

Researchers use poliovirus to destroy neuroblastoma tumors in mice

The cause of one notorious childhood disease, poliovirus, could be used to treat the ongoing threat of another childhood disease, neuroblastoma.

Researchers uncover genetic sequence responsible for rare form of pancreatic cancer

Pancreatic ductal adenocarcinoma is an almost uniformly fatal disease regardless of the stage at time of diagnosis. However, a small percentage of patients develop a form of ductal adenocarcinoma associated with cystic lesions that can be detected earlier, is less aggressive and has a 50 percent long-term survival rate.

Interferon gamma identified as one of the signaling proteins involved with tumor relapse

Researchers at Virginia Commonwealth University's Massey Cancer Center studying the interaction between the immune system and cancer cells have identified interferon gamma as one of the signaling proteins involved with tumor relapse.

Islet cell trasnplant without immunosuppressive drugs successful in mice

Scientists at Weill Cornell Medical College may have reached a breakthrough in the search for a lasting cure for type 1 diabetes.

11 Mar 2007

Inhaled Celecoxib shows new promise for lung cancer treatment

In recent years, Cycloxygenase (COX)-2 has emerged as a therapeutic target for the prevention and treatment of various types of cancers.

6 Mar 2007

Green tea and COX-2 inhibitors combine to slow growth of prostate cancer

Drinking a nice warm cup of green tea has long been touted for its healthful benefits, both real and anecdotal. But now researchers have found that a component of green tea, combined with low doses of a COX-2 inhibitor, could slow the spread of human prostate cancer.

Metabolic response to colitis varies depending upon whether inflammation is chronic or acute

A new study being published by the American Physiological Society finds that the body responds differently to colitis (inflammation of the colon) based on whether the disease is acute (sharp and brief) or chronic (long-term).

Genetically caused deafness may be reversible by compensating for a missing protein

Emory University researchers have found that in mice, increasing the amount of the protein connexin26 in the ear's cochlea compensates for an absence of another protein, connexin30.

Old drug pentylenetetrazole may improve learning and memory in Down syndrome victims

Researchers in the United States have discovered that an old drug once used to study epilepsy substantially improved learning and memory in mice with Down syndrome symptoms.

26 Feb 2007

Mechanism driving iron overload in thalassemia identified

Led by researchers at Weill Cornell Medical College in New York City, an international group of scientists has pinpointed a specific genetic relationship as the cause of dangerous iron overload in persons with a form of the inherited blood disease, beta-thalassemia.

Dipeptidyl peptidase I critical for early growth of abdominal aortic aneurysms

Surgery is the only treatment for an abdominal aortic aneurysm, a weak spot in the body's main artery that dilates dangerously over time.

13 Feb 2007

Nanoparticle boost for antitumor vaccines

Researchers have known for some time that certain sequences of synthetic DNA induce potent immune responses when injected into animals and humans.

12 Feb 2007

A plasminogen-activating protease specifically controls the development of primary pneumonic plague

The deadly attack of the bacterium that causes pneumonic plague is significantly slowed when it can't make use of a key protein, scientists at Washington University School of Medicine in St. Louis report in Science.

28 Jan 2007

TrkB and its role in learning and memory

For the first time researchers investigate the molecular basis of memory in living mice.

9 Jan 2007

Scientists spot mechanism behind promising new sleep drug

An experimental drug called gaboxadol may soon help millions of bleary-eyed insomniacs get to sleep, and a multi-center team of U.S. scientists believes they've pinpointed just how the drug works.

Effective test for screening Huntington's disease drugs

A test using cultured cells provides an effective way to screen drugs against Huntington's disease and shows that two compounds - memantine and riluzole - are most effective at keeping cells alive under conditions that mimic the disorder, UT Southwestern Medical Center researchers report.

Scientists discover how brain turns on system designed to protect nerve cells from toxic "free radicals"

Scientists at Dana-Farber Cancer Institute report they have found how the brain turns on a system designed to protect its nerve cells from toxic "free radicals," a waste product of cell metabolism that has been implicated in some degenerative brain diseases, heart attacks, strokes, cancer, and aging.
