Australian platypus research has implications for understanding the evolution of human sex determination

The mystery surrounding sex determination of the unique Australian platypus has yielded a surprising secret: it has 10 sex chromosomes.

High levels of a protein called LRP6 can make cancer cells more aggressive

The protein's ability to enhance tumor development suggests that the gene that codes for LRP6 is an oncogene--a gene that contributes to tumor development when overactivated.

New understanding of how poxviruses jump from species to species

A Canadian study conducted at Robarts Research Institute sheds new light on how poxviruses can jump from species to species -- and will lead to further exploration of another potential candidate in the emerging field of “oncolytic viruses” to fight cancer.

Calorie restriction prevents certain aging-related changes in the brain

Severe calorie restriction prevents certain aging-related changes in the brain, including the accumulation of free radicals and impairments in coordination and strength, according to a mouse study at Washington University School of Medicine in St. Louis.

Potential new protein marker for prognosis of breast and ovarian cancer

The researchers matched tumor samples to outcomes in about 100 patients diagnosed with either breast or ovarian cancer and found that a low level of Rab25 protein on a patient's cancer sample was associated with a better clinical outcome in both cancer types.

Exercise protects brain cells affected by Parkinson's

In an animal model of Parkinson's, exercise prevents degeneration of nerve cells that are normally impaired or destroyed by the disease, according to University of Pittsburgh researchers.

Blocking gene opens avenues for treating prostate cancer

Cancer Research UK scientists in Oxford have found a new way to make prostate cancer succumb more readily to currently used treatments.

Detecting diseases with no more to work with than a drop of blood

The dream of monitoring a patient's physical condition through blood testing has long been realized. But how about detecting diseases in their very early stages, or evaluating how they are responding to treatment, with no more to work with than a drop of blood!

New way to study individual living bacteria cells and analyze their chemistry

Researchers at the U.S. Department of Energy's Argonne National Laboratory have found a new way to study individual living bacteria cells and analyze their chemistry.

Key discovery toward understanding mechanism associated with uncontrollable muscular movements

Neurodegenerative diseases such as Alzheimer's, Parkinson's, Lou Gehrig's and Huntington's exhibit loss of nerve function in different ways, from memory lapses to uncontrollable muscular movements, but it is now believed that these diseases share many common molecular mechanisms.

Lag-3 gene dampens immune responses by controlling regulatory T-cell function

The discovery that the Lag-3 gene acts as a brake to prevent immune system responses from running out of control solves a mystery that has puzzled researchers since the gene was discovered 14 years ago.

Strong-flavored onions could potentially be great for fighting cancer

Researchers at Cornell University have found, in preliminary lab studies, that members of the onion family with the strongest flavor — particularly New York Bold, Western Yellow and shallots — are the best varieties for inhibiting the growth of liver and colon cancer cells.

Research opens new possibilities for the treatment of metabolic disorders such as diabetes and obesity

For the first time, researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected with the Catholic University of Leuven have shown clearly that receptors in yeast cells detect and react to nutrients in the cell.

Molecule that helps DNA replicate may make good target for cancer therapy

In order to divide, cells must first replicate their chromosomes. Cells use an array of proteins to accomplish the job, including a large enzyme complex that synthesizes new strands of DNA.

Research findings will likely aid efforts to develop a vaccine for Leishmania major

Researchers at Washington University School of Medicine in St. Louis and the University of Pennsylvania have found an immune system cell can "remember" a parasite's attack and help the body mount a more effective defense against subsequent invasions by the same parasite.

Genetic research offers insight into Sjögren's syndrome and the general developmental machinery of the immune system

By knocking out a single gene in mice, immunologists at Duke University Medical Center have mimicked a little-understood autoimmune disorder in humans.

Researchers have uncovered a specific signaling mechanism that contributes to the development of colorectal cancer

The discovery furthers the understanding of mechanisms that contribute to disease progression and provides new avenues for development of therapies for colorectal cancer.

New medication to prevent colon cancer

A Stony Brook University researcher is testing a new form of aspirin--one that is much more potent than its commercially available counterpart, but with almost none of the side effects--to determine whether it can be used to prevent colon cancer in patients who are prone to the disease.

21 Oct 2004

Common antibacterial and antifungal ingredient used in tooth paste may protect against skin cancer

According to new studies, sanguinarine was shown to enhance production of proteins that induce cell death, or apoptosis, in cells damaged by ultraviolet-B (UVB) radiation.

Researchers identify a protein that could banish allergies

The suffering of millions of people with allergies could one day be eased thanks to new research from UK investigators. Findings from the University College London branch of the Ludwig Institute for Cancer Research (LICR), published in the Oct 2004 issue of Nature, detail how inactivating a key signalling molecule called p110delta reduced the effect of allergies on mice.
