Researchers identify protein called EMP-1 that is present in the tumors of patients who fail to respond to treatment with gefitinib

By the time the human genome was mapped, cancer researchers had already begun investigating the proteins that were encoded by these newly identified genes.

Latest findings on aspirin resistance

Treatment failures occur with any drug and aspirin is no exception. Evidence is growing that some people will not respond to the anti-coagulant action of aspirin and the drug will not protect against cardiovascular events despite its regular intake.

Enzyme involved in blood pressure regulation may also influence how the body responds to exercise

New research suggests why some older adults who exercise have better physical function than others. Surprisingly, researchers found that an enzyme involved in blood pressure regulation may also influence how the body responds to exercise.

MicroRNAs play an important role in regulating oogenesis

Researchers at Northwestern University and Carnegie Mellon University have found that a recently described class of molecules called microRNAs (miRNAs) play an important role in regulating oogenesis, the process by which females make eggs.

Researchers develop new diagnostic methods to better detect future monkeypox or smallpox outbreaks

The research also sheds new light on the 2003 monkeypox outbreak in the Midwest - monkeypox is closely related to smallpox. This new information suggests that the 2003 outbreak was larger than the 72 cases reported by the Centers for Disease Control and Prevention (CDC).

DDT resistance in flies carries no cost

For those concerned with the troublesome effects of genetic resistance to drugs and pesticides, the conventional wisdom of evolution offers a reassuring word: In the absence of the original chemical threat, most resistance mutations would cause a disadvantage to their hosts and might be expected to quickly leave the genetic landscape once the use of a drug or insecticide is suspended or withdrawn.

Study results reaffirm cyclin D1 as a candidate target for molecular therapeutic control of breast tumor development

For about a decade, scientists have recognized that many cases of hereditary breast cancer result from a mutation of a specific gene called BRCA1, which, in its normal state, helps keep tumor formation in check. About five to 10 percent of breast cancer cases arise from these genetic miscues, about half of which are linked to the abnormal functioning of BRCA1.

Low levels of folate linked to lower birth rates

Mothers-to-be with lower levels of the vitamin folate in their body during early pregnancy are more likely to have babies with lower, or less healthy, birth weights, a study has revealed.

Discovery may lead to new diagnostic tests for immunoglobulin A (IgA) deficiency and common variable immunodeficiency (CVID)

Defects in a single gene can result in two immune system disorders that leave affected individuals vulnerable to frequent or unusually severe infections, according to new findings reported in the August issue of Nature Genetics.

Sources of magnetic fields in the home

The UKCCS published the results of exposure to power frequency magnetic fields in 1999 followed by a paper on residential proximity to power lines in 2000.

Natural killer cells help understand responses to bone marrow transplants

Scientists have discovered that a group of important immune system cells has a surprising resemblance to cinematic British superspy James Bond: the cells receive a "license" that allows them to unleash their most potent attacks on enemies.

MDMA/Ectasy could lead to new treatments for Parkinson's disease

Researchers at Duke University have revealed new clues about Parkinson's disease which might one day lead to new treatments.

New study aims to understand the intricate biochemistry governing gene regulation

In their efforts to understand the complex biology of life, scientists often seek to isolate individual elements of the puzzle for study, to break the problem down to a more manageable size. Single genes and molecules are closely analyzed to better understand their specific interactions with other single entities within larger systems.

Researchers pinpoint specific cause of defects in motor learning in Fragile X patients

While researchers have long known the genetic defect underlying Fragile X syndrome, they are still tracing how that defect creates the complex mix of mental retardation, hyperactive behavior, attention deficits, and other problems in the disorder.

Bone marrow-derived cells fail to meet high expectations says Bonn study

Adult stem cells taken from bone marrow are the "shooting stars" of their field. Many research scientists have been speculating that the cells might be able to pass through the blood into diseased organs and replace defective tissue. Such cells are seen as the potential key to the treatment of certain muscle diseases.

Scientist have found an unexpected effect of the interaction of PTEN and p53 genes in early stage prostate cancer

Prostate cancer, the second leading cause of cancer death for men in the United States, is caused by changes in several tummor suppressor genes including PTEN and p53. Up to 70 percent of men with prostate cancer have lost one copy of the PTEN gene at the time of diagnosis, and p53 is absent in a high number of patients with advanced prostate cancer.

First evidence that complex genetic interactions account for autism risk

Using a novel analysis of the interactions among related genes, Duke University Medical Center researchers have uncovered some of the first evidence that complex genetic interactions account for autism risk. The Duke team found that the brain mechanism that normally stops or slows nerve impulses contributes to the disease.

Customized gene chip offers clues to prognosis in cases of neuroblastoma

Rather than covering the entire genome, the microarray focuses on suspect regions of chromosomes for signs of deleted genetic material known to play a role in the cancer.

Vimentin marker detects colon cancer in 46 percent of patients

Researchers at Case Western Reserve University School of Medicine and the Ireland Cancer Center of University Hospitals of Cleveland report identifying a new DNA gene marker, vimentin, that was shown in a recent study to be three times more effective in detecting colon cancer than the standard doctor's office test that detects blood in the stool.

Scientists use gene transfer to prevent retinoschisis

University of Florida scientists used a healthy human gene to prevent blindness in mice with a form of an incurable eye disease that strikes boys.
