New guideline to improve IHC testing for expression status of ER and PgR in breast cancer issued

The College of American Pathologists and the American Society of Clinical Oncology today issued a joint guideline aimed at improving the accuracy of immunohistochemistry testing for the expression status of estrogen and progesterone receptors in breast cancer. The two groups conducted a systematic review of medical research literature in partnership with Cancer Care Ontario to develop the recommendations.

Researchers transform yellow fever vaccine to fend off mosquito borne parasites that cause malaria

There is no vaccine for malaria, which sickens almost a quarter of a billion people each year and kills a child every 30 seconds. That could be changing: researchers at The Rockefeller University have genetically transformed the yellow fever vaccine to prime the immune system to fend off the mosquito borne parasites that cause the disease.

Study may yield more targeted therapies for telomere associated diseases

A new study at the University of Leicester is examining a sequence of DNA- known as telomeres - that varies in length between individual.

Genetic variation can predict how people infected with hepatitis C react to treatment: Scientists

A small genetic change can predict how people infected with hepatitis C react to treatment, paving the way to personalised therapy for this difficult to treat disease, the annual conference of the European Society of Human Genetics will hear today (Sunday 13 June). Dr. Zoltan Kutalik, from the Department of Medical Genetics, University of Lausanne, Switzerland, will tell delegates that individuals with this change, in a gene encoding for the antiviral cytokine (cell-signalling molecule) interferon lamda, reacts less well to treatment.

New breakthrough in stem cell and tissue engineering

The mechanism by which 'polycomb' proteins critical for embyronic stem cell function and fate are targeted to DNA has been identified by UCL scientists.

Researchers identify 2,630 proteins that reside in human spinal fluid

A research team has sharply expanded scientific knowledge of the composition of human spinal fluid. The researchers have identified 2,630 proteins that reside in fluid that is considered "normal," a number nearly three times as great as the total number of proteins previously identified. Another striking finding was that more than half (56%) of the proteins were relatively unique to the spinal fluid and not found in blood.

Research on genetic mutations could lead to accurate diagnosis of USH, says scientist

Usher syndrome, an inherited condition involving both hearing and vision loss, is not a simply recessively inherited disease, a scientist will tell the annual conference of the European Society of Human Genetics today (Saturday). Dr. Hanno Bolz, Associate Medical Director of the Bioscientia Centre for Human Genetics, Ingelheim, Germany, and active in teaching and research at the University Hospital of Cologne, will say that his team's research challenges the traditional view that USH was inherited as a single gene disorder, and shows that it may result from at least two different genetic mutations.

Anti-infectives could circumvent the problem of antibiotic resistance

For a successful infection, bacteria must outwit the immune system of the host. To this aim, they deliver so-called virulence factors through a transport channel located in the bacterial membrane.

ACT's hESC line MA135 approved for federal funding

Advanced Cell Technology, Inc. announced today that human embryonic stem cell line MA135 was unanimously approved for federal funding at the 100th Meeting of the Advisory Committee to the Director National Institutes of Health. In addition to MA135, seven additional stem cell lines derived at ACT are currently under review by the NIH.

White blood cells with receptors for both virus and nerve proteins may assault nerves after fighting infection

A virus infection can incite the body to attack its own nerve tissue by activating unusual, disease-fighting cells with receptors for both viral and nerve proteins. The dual-receptor observation suggests a way brain and spinal cord nerve damage might be triggered in susceptible young adults afflicted with multiple sclerosis.

Interactions between human and microbial cells determine health, physical well-being: Researchers

At birth, your body was 100-percent human in terms of cells. At death, about 10-percent of the cells in your body will be human and the remaining 90-percent will be microorganisms. That makes you a "supraorganism," and it is the interactions between your human and microbial cells that go a long way towards determining your health and physical well-being, especially your resistance to infectious diseases.

Study results of genes regulated by ERB published in Journal of Biological Chemistry

Bionovo Inc. today announced the publication of results from a study demonstrating the three distinct classes of genes regulated by estrogen receptor beta. The results are published in the Journal of Biological Chemistry. This is an important discovery for future development of selective drugs regulating this pathway.

Emerging science of epigenetics offers new insights at crossroads of genes and the environment: Article

An emerging arm of molecular biology is introducing a new interpretation of traditional concepts of human disease, explains an article published today in Nature. According to author Dr. Arturas Petronis at the Centre for Addiction and Mental Health, the emerging science of epigenetics is offering new insights at the crossroads of genes and the environment, or nature and nurture. Dr. Petronis is head of the Krembil Family Epigenetics Laboratory at CAMH and an international expert in the field.

In vivo structure of senile plaques in brains of people with Alzheimer's disease

A team of scientists from Britain and the United States believe they may have identified the true in vivo structure of the senile plaques that are characteristically found in the brains of people with Alzheimer's disease.

Anoxia-induced suspended animation helps survive hypothermia

How is it that some people who apparently freeze to death, with no heart rate or respiration for extended periods, can be brought back to life with no long-term negative health consequences? New findings from the laboratory of cell biologist Mark B. Roth, Ph.D., of Fred Hutchinson Cancer Research Center, may help explain the mechanics behind this widely documented phenomenon.
