Profile of immune cells in axillary lymph nodes predicts disease-free survival in breast cancer

Breast cancer often spreads through the lymph nodes in the arm pits (so-called axillary lymph nodes), and whether these lymph nodes are tumor-free or contain small metastases is an important factor in the decision of how aggressively to treat a patient.

Significant new breakthroughs in understanding how the genes in mammals are controlled

An international consortium of genome research institutes and investigators, including Jackson Laboratory Staff Scientists Carol J. Bult, Ph.D., and Martin Ringwald, Ph.D., has reported significant new breakthroughs in understanding how the genes in mammals are controlled.

New ways to enhance or block fertilization

Researchers have capitalized on the unique properties of a sperm cell to follow cell membrane fusion as it occurs during fertilization, tracking the full cascade of events for the first time. The findings could reveal new ways to enhance or block fertilization, as well as how to control the secretion of neurotransmitters and hormones such as insulin.

Design of wide-spectrum inhibitors targeting coronavirus main proteases

Coronaviruses - the family of viruses that causes the common cold - gained widespread recognition when the deadly severe acute respiratory syndrome, familiarly known as SARS, killed at least 800 people in 2003.

Genetic hot spots double the risk of early heart disease

According to researchers in the UK there are six genetic "hotspots" that can double the risk of developing early heart disease.

Double whammy of vitamin D and anti-inflammatory zaps prostate cancer cells

Scientists from Stanford University say they have discovered that vitamin D, known as the "sunshine vitamin,"can limit the growth of prostate cancer cells when combined with non-steroidal anti-inflammatory drugs.

New way to assess risk of breast cancer recurrence

Currently, the best way to predict whether a breast cancer is likely to recur is to determine whether tumor cells have invaded the lymph nodes near the breast.

Human tissue grown from stem cells, available for transplant in the next four years

A team of researchers from the University of Liverpool in the UK have embarked on an ambitious project which could see human tissue grown from stem cells, available for transplant in the next four years.

Gene B-myb essential in preventing tumors

A new study has confirmed that research done with zebrafish may be able to play a critical role in learning about the genetic basis of cancer and the mutations that can lead to it - and identified one gene in particular, B-myb, whose function is essential to preventing tumors.

Vitamin B may do more harm than good in heart attack patients

Researchers from Norway have found that treating patients who have had a heart attack with high doses of B vitamins does not lower the risk of getting another heart attack or stroke. Contrary to expectations, B vitamins may do more harm than good.

Use of the antiplatelet drug clopidogrel before a coronary angioplasty reduces risk of cardiovascular death

Use of the antiplatelet drug clopidogrel before a coronary angioplasty reduced the risk of cardiovascular death, heart attack or stroke within 30 days following the procedure, according to an article in the September 14 issue of JAMA: The Journal of the American Medical Association.

Human embryonic stem cell lines accumulate changes in their genetic material over time

The findings do not limit the utility of the cells for some types of research or for some future clinical applications, the researchers say, but draw attention to the need to closely monitor stem cell lines for genetic changes and to study how these alterations affect the cells' behavior.

Researchers discover one of the reasons why melanoma is so ruthless

About 60,000 Americans will be diagnosed with melanoma this year, says the American Cancer Society, and 10,000 of those cases will be fatal. If not caught in the early stages, melanoma can be a particularly virulent form of cancer, spreading through the body with an efficiency that few tumors possess.

New blood pressure-lowering drugs reduce stroke risk by 50%

According to researchers the new types of blood pressure-lowering drugs are more effective in preventing strokes and heart attacks and save even more lives.

Researchers to test whether cannabinoids can help chronic obstructive pulmonary disease patients

Researchers from Imperial College London are looking for volunteers to test whether cannabinoids, the active ingredient of cannabis, can be used to alleviate the sensation of breathlessness caused by illnesses such as chronic obstructive pulmonary disease (COPD).

Rett Syndrome gene discovery

Adrian Bird of the University of Edinburgh and colleagues report in the online issue of Molecular Cell that the "Rett Syndrome protein", MeCP2, only binds to genes with a specific sequence of nucleotide bases. This knowledge will aid in the identification of the genes that are regulated by the gene MECP2

Medication before angiograph significantly reduces risk of heart attack

According to new research if patients are given the a drug which reduces platelet activity in the blood risk of heart attack and cardiovascular death before and after angioplasty is reduced.

Macrophages kill bacteria - but not always

Macrophages are effective weapons used by our immune system to absorb and digest pathogenic intruders. Some bacteria, however, can subvert this defence mechanism and even multiply within the macrophages.
