Asian poison ivy like plant may stop prostate cancer

The croton plant, long known to oriental herbalists and homeopaths as a purgative, has an oil in its seeds that shows promise for the treatment of prostate cancer – the second leading cause of cancer death in men in the United States. The active ingredient in the oil is 12-O-tetradecanoylphorbol-13-acetate, a compound generally known as TPA.

Research suggests the orlistat drug could be used to fight cancer and obesity

The Burnham Institute’s Jeffrey Smith, Ph.D., has discovered that orlistat, commonly prescribed as an anti-obesity drug, has a positive side-effect: it inhibits cancer growth. Dr. Smith made this discovery using an activity-based proteomics screening technique developed in his laboratory that makes it possible to identify active targets and simultaneously screen for their inhibitors.

Lupus Discovery May Lead To Improved Drugs

In an important development in the treatment of lupus as well as certain cancers, scientists at the Feinberg School of Medicine at Northwestern University have discovered how autoimmune lupus T cells stave off programmed cell death and drive production of autoantibodies directed against the body’s own DNA.

New optical glucose sensor could mean help for diabetics

Researchers at the University of California, Santa Cruz, have developed a novel optical glucose sensor that could be used to provide continuous monitoring of glucose levels in diabetics and hospitalized patients. Recently published studies showed that the sensor detects glucose under physiological conditions, giving a reversible fluorescent signal that changes intensity in response to changes in the concentration of glucose.

New therapies that may treat cancers

Scientists at the Johns Hopkins Kimmel Cancer Center and Howard Hughes Medical Institute have found mutations in a gene linked to the progression of colon and other cancers. The research findings, may lead to new therapies and diagnostic tests that target this gene.

Treatment for ovarian cancer by gene targeting

Targeting and inactivating a key gene could be a subtle and effective treatment for certain types of ovarian cancer, Scottish researchers suggest in a study published in Clinical Cancer Research.

New treatment for heart attacks

A team led by scientists at The Scripps Research Institute has developed a potential new treatment for heart attacks. The therapy inhibits fluid leakage from cardiac blood vessels following a heart attack and thereby significantly prevents long-term heart damage and improves survival.

Scientists identify blood development gene which may aid the fight against cancer and leukemia

Researchers at Harvard-affiliated Dana-Farber Cancer Institute have pinpointed a crucial gene on which the normal development of the body's entire blood system depends. If the gene is absent, even the most basic blood stem cells cannot be generated. In a mutated form, this gene can cause a rare and devastating form of leukemia.

Drug Based on Brain Chemical Could End Narcolepsy and Insomnia

Researchers at UT Southwestern Medical Center at Dallas have discovered a potentially new avenue for treating human narcolepsy, and the work may also lead to more effective ways for insomniacs to boost their wakefulness during the daytime.

Cigarette Smoking May Lower Rates of Neurodegenerative Diseases like Parkinson's and Alzheimer's

While the health risks of tobacco are well known, several studies have shown that people with a history of cigarette smoking have lower rates of neurodegenerative diseases like Parkinson's and Alzheimer's disease. However, the explanations for nicotine's neuroprotective effects continue to be debated.

Gene Responsible for The Most Common Form of Diabetes

International research teams studying two distinct populations have found variants in a gene that may predispose people to type 2 diabetes, the most common form of the disease. The researchers, who collaborated extensively in their work, report their findings in companion articles in the April issue of Diabetes.

Stem cells and female reproduction: lessons from an unexpected source

Baltimore, MD. The recent findings reported in Nature (March 11, 2004) by Jonathon Tilly’s group at Harvard Medical School, show that female mice produce stem cells that give rise to eggs. This result overturns previous notions about mammalian reproduction, which held that females are born with all the eggs that they will ever have and that the decline in egg quality that occurs after a certain age is due to an extended aging process. What mammalian research has not been able to address at this point, however, is how these stem cells operate, what prompts them to develop into eggs, and why they are eventually lost. To answer these questions we must turn to our cousin the fruitfly.

Molecules That Trigger a Heartbeat

Two biomedical engineering students at Johns Hopkins are mapping the interaction of molecules within a cardiac cell, describing microscopic movements that could be critical for maintaining a healthy heartbeat. The students, seniors Bhuvan Srinivasan and Carol Xiaoying Koh, have presented their findings at two prestigious computational biology conferences and are now collaborating with their faculty supervisor on a paper for a scientific journal.
