LKB1 gene - new lung tumor-suppressor

Collaborating scientists in Boston and North Carolina have found that a particular gene can block key steps of the lung cancer process in mice.

Discovery of mechanism in malaria parasite that helps it adapt to infected individuals

Plasmodium falciparum is responsible for the most severe forms of human malaria.

Biologists discover one reason why chromosomes break, often leading to cancer

In the past ten years, researchers in genome stability have observed that many kinds of cancer are associated with areas where human chromosomes break.

Tailor-made antidepressants

In spite that the causes of depression have not still been fully identified, scientists acknowledge that genetic and environmental factors play a common role in the onset of this disorder.

Unlocking proteins from their cellular shell

Applying physical stress to cells, researchers at the University of Pennsylvania have demonstrated that everyday forces can alter the structure of proteins tucked within cells, unfold them and expose new targets in the fight against disease.

Innovative gene therapy research for muscular dystrophy

A major grant of approximately $10 million from the National Institutes of Health will help investigators at Columbus Children's Research Institute (CCRI) at Columbus Children's Hospital learn more about strategies to treat muscular dystrophy, potentially leading to two new gene therapy approaches.

Gene fusion subtypes in prostate carcinoma have clinical implications

Building on an earlier study that used Oncomine to identify ETS-fusion proteins in prostate cancer (Science, Oct 28 2005), Tomlins et al. report the identification of four additional classes of ETS rearrangements in prostate cancer, each of which activates ETV1 by a different genetic mechanism (Nature, Aug 2 2007).

Possible anthrax drug targets

In the American government's biodefense efforts, the potential for terrorists to cause a deadly anthrax outbreak remains a significant concern, six years after the letter attacks that shook the nation shortly after 9/11.

Gene variation makes people with depression more likely to respond to the medication citalopram

A variation in a gene called GRIK4 appears to make people with depression more likely to respond to the medication citalopram (Celexa) than are people without the variation, a study by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, has found.

Detection of gene fusions in prostate cancer

Researchers at the University of Michigan Comprehensive Cancer Center have discovered how genes turn on the switch that leads to prostate cancer.

Discovery of molecular pathway that detects and eliminates defective messenger RNAs from red blood cells

Other such pathways - known as surveillance pathways - operate in a more general way, in many cell types. Knowing how this specific surveillance system works can help researchers better understand hereditary diseases, in this case, thalassemia, a form of anemia, which is the most common genetic disorder worldwide.

Phase II study of TroVax vaccine in patients with metastatic colorectal cancer

A therapeutic cancer vaccine has shown effectiveness when given alongside chemotherapy to patients with metastatic colorectal cancer in a phase II trial, according to researchers at Oxford BioMedica (UK) Ltd.

Specific microRNA, called miR-21, helps liver cancer develop

New research shows how a particular small molecule blocks the activity of a cancer-suppressing gene, allowing liver-cancer cells to grow and spread.

Prototype vaccine against tuberculosis

Using a novel approach, researchers at the Albert Einstein College of Medicine of Yeshiva University have developed a prototype vaccine against tuberculosis (TB) that works better in animal models than the only TB vaccine now available.

Colon cancer may benefit from hormone replacement therapy

Researchers at the Kimmel Cancer Center at Jefferson in Philadelphia have found new evidence suggesting that colon cancer is actually a disease of missing hormones that could potentially be treated by hormone replacement therapy.

Cell injury caused by brushing may help keep gums healthy

One way regular brushing may help keep gums firm and pink is, paradoxically, by tearing open cells, researchers have found.

Aggressive therapy best for certain acute myeloid leukemia patients

A new study suggests that acute leukemia patients whose cancer cells show a genetic change that usually predicts a swift return of the disease following remission may remain disease-free longer when given aggressive therapy.

2 Aug 2007

Fear protein found

A University of Iowa study shows that loss or chemical inhibition of a protein, known as acid sensing ion channel protein (ASIC1a), reduces innate fear behavior in lab animals, making normally timid mice relatively fearless.

Biological markers of narcolepsy

The first report to identify the biological markers of narcolepsy using gene expression in white blood cells finds that the MX2 gene, which is relevant to the immune system, is significantly less expressed in narcoleptics compared with normal subjects.
