Researchers clear hurdle on path toward gene-therapy treatment for disease

One of the most difficult aspects of working at the nanoscale is actually seeing the object being worked on. Biological structures like viruses, which are smaller than the wavelength of light, are invisible to standard optical microscopes and difficult to capture in their native form with other imaging techniques.

Breast cancer classification algorithm to identify 20 gene signature developed using Microsoft Excel

Using readily available computer programs, researchers have developed a system to identify genes that will be useful in the classification of breast cancer. The algorithm, described in BioMed Central's open access Journal of Experimental & Clinical Cancer Research will enable researchers to quickly generate valuable gene signatures without specialized software or extensive bioinformatics training.

Researcher awarded $1.8M grant to investigate sex differences in anxiety

Anxiety disorders afflict women twice as often as men, but estrogen might not be the reason. Testosterone, though, could be. That is one of the preliminary findings in the lab of Florida State University researcher Mohamed Kabbaj, associate professor in the College of Medicine. He recently was awarded a five-year, $1.8 million grant from the National Institute of Mental Health to investigate the sex differences in anxiety.

Estradiol prevents vascular permeability following hemorrhagic shock: Study

A study published in the September 2010 issue of SHOCK by Dr. Ed W. Childs and colleagues at Scott & White Healthcare looks at how female versus male rats fared after suffering a trauma and subsequent hemorrhagic shock who were given Estradiol (estrogen). In the study, the Estradiol prevented vascular permeability following hemorrhagic shock.

Agensys commences AGS-16M8F ADC Phase I clinical trial for renal cancer

Agensys, Inc., an affiliate of Tokyo-based Astellas Pharma Inc., today announced that they have initiated a Phase I clinical trial of AGS-16M8F an antibody-drug conjugate (ADC) that is being developed for the treatment of metastatic renal cancer. An ADC uses the specific binding properties of an antibody to target a toxin in tumor cells, resulting in selective tumor cell killing.

MIRACLE project to develop lab-on-chip system for diagnosing cancer

Today, at the Engineering in Medicine and Biology Conference in Buenos Aires (Argentina), imec and its project partners announce the launch of the European Seventh Framework Project MIRACLE. The MIRACLE project aims at developing an operational lab-on-chip for the isolation and detection of circulating and disseminated tumor cells in blood.

Research on fruit flies suggest starvation allows sleep deprivation

As anyone who has ever struggled to keep his or her eyes open after a big meal knows, eating can induce sleepiness. New research in fruit flies suggests that, conversely, being hungry may provide a way to stay awake without feeling groggy or mentally challenged.

First genetically engineered rat derived from rat ES cells developed with StemCells' technology

StemCells, Inc. announced today that its technology was recently used by independent researchers to achieve the first genetically engineered rat derived from rat embryonic stem (ES) cells. This breakthrough, published this month in the international peer-reviewed journal Nature, opens the door to the types of genetic manipulations previously only possible in mice, and paves the way for modeling a broader range of human diseases with the rat.

Neutralizing key toxin associated with Staph aureus bacteria reduces severity of skin and soft-tissue damage

Scientists from the National Institutes of Health and University of Chicago have found a promising treatment method that in laboratory mice reduces the severity of skin and soft-tissue damage caused by USA300, the leading cause of community-associated Staphylococcus aureus infections in the United States.

Innate immune processes sufficient for driving silicosis: Study

For the nearly 2 million U.S. workers exposed to silica dust each year, a new discovery may help prevent or treat the development of chronic lung diseases related to this exposure. In the September 2010 issue of the Journal of Leukocyte Biology scientists from Montana and Texas use mice to show for the first time that the part of our immune system responsible for keeping airways clean and free of contaminants (innate immunity) can cause inflammation and symptoms of disease.

Study on kidneys may help to treat high blood pressure

A study of the body system that deals with Americans' love affair with salt may yield more insight into why so many end up hypertensive and how to better treat them.

Research finds link between chronic heart failure, iron deficiency

Iron plays a key role in human homeostasis. It is essential for growth and survival, and is a vital ingredient in numerous processes including erythropoiesis, oxygen transport and storage, oxidative metabolism in the skeletal and heart muscle, synthesis and degradation of lipids, carbohydrates, DNA and RNA. Important though it is, iron metabolism must be precisely controlled because iron is insoluble and excess levels can be toxic.

Salpingo-oophorectomy and mastectomy decrease risk of cancer in women with BRCA1/2 gene mutations

Women at increased risk of breast and ovarian cancer because of inherited mutations of the BRCA1 or BRCA2 genes who had prophylactic mastectomy or salpingo-oophorectomy (removal of the fallopian tubes and ovaries) had an associated decreased risk of breast cancer and ovarian cancer, according to a study in the September 1 issue of JAMA.

High-fat diet during puberty increases risk of breast cancer

Girls eating a high-fat diet during puberty, even those who do not become overweight or obese, may be at a greater risk of developing breast cancer later in life, according to Michigan State University researchers.

'Sprouty' protein linked to regulation of bone mass and body fat

Here's good news for anyone trying to lose weight or has osteoporosis: Scientists from Maine are on the trail of a weight loss drug that may revolutionize how we treat these two conditions. In a new research report published in the September 2010 print issue of The FASEB Journal, the researchers describe a newly discovered protein, called "Sprouty," responsible for regulating body fat and bone mass. Then they manipulated how much of this protein was expressed in different groups of mice specially bred to have some human genes.

High selenium intake associated with decreased risk of bladder cancer

According to results of a study published in the September issue of Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research, selenium intake is associated with decreased risk of bladder cancer.

Research on adult mammary stem cells may help to cure breast cancer

For the first time, researchers at Fred Hutchinson Cancer Research Center have identified and isolated adult mammary stem cells in mice. Long-term implications of this research may include the use of such cells to regenerate breast tissue, provide a better understanding of the role of adult stem cells in breast cancer development, and develop potential new targets for anti-cancer drugs.
