Rotational motion plays a critical role in ability of breast cells to form acini

In a study that holds major implications for breast cancer research as well as basic cell biology, scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini.

First genome-wide study of high-altitude adaptations in Ethiopians

Over many generations, people living in the high-altitude regions of the Andes or on the Tibetan Plateau have adapted to life in low-oxygen conditions. Living with such a distinct and powerful selective pressure has made these populations a textbook example of evolution in action, but exactly how their genes convey a survival advantage remains an open question. Now, a University of Pennsylvania team has made new inroads to answering this question with the first genome-wide study of high-altitude adaptations within the third major population to possess them: the Amhara people of the Ethiopian Highlands.

Scientists identify pathway that activates hepsin on the surface of breast tumor cells

Scientists from the University of Helsinki and from UCSF have exposed a cell pathway that breast tumor cells use to destruct local tissue neighborhood. Cancer cells may use this pathway to free themselves from mammary epithelial tissue architecture, to spread to surrounding tissues. The cell pathway, the researchers found, is a biochemical chain of events leading to activation of a protein-cleaving enzyme on the surface of the tumor cells.

Clinical trial to compare Aria's prenatal test and standard first-trimester screening for T21

Aria Diagnostics, a molecular diagnostics company, announced that it is initiating a blinded, multicenter clinical trial that compares its non-invasive prenatal test with the standard first-trimester screening test (serum screening and nuchal translucency ultrasound alone and in combination) to detect Trisomy 21, which is associated with Down syndrome.

Scientists identify two genes involved in major symptoms of MeCP2 duplication disorder

The anxiety and behavioral issues associated with excess MeCP2 protein result from overexpression of two genes (Crh [corticotropin-releasing hormone] and Oprm 1 [mu-opioid receptor MOR 1]), which may point the way to treating these problems in patients with too much of the protein, said Baylor of Medicine scientists in a report that appears online in the journal Nature Genetics.

Non-eosinophilic disease more prevalent in patients with mild-to-moderate asthma

A large percentage of patients with mild-to-moderate asthma have persistently non-eosinophilic disease which may not respond to currently available anti-inflammatory treatments, according to a new study.

Positive preliminary results from Alnylam's Phase I ALN-PCS trial on severe hypercholesterolemia

Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today the achievement of positive preliminary results from its ongoing clinical trial of ALN-PCS, an RNAi therapeutic targeting PCSK9 for the treatment of severe hypercholesterolemia.

Non-invasive test for early detection of fetal gender

A new research study published in the January 2012 edition of The FASEB Journal describes findings that could lead to a non-invasive test that would let expecting mothers know the sex of their baby as early as the first trimester.

Study assesses evidence of immunosuppression in sepsis

An analysis of lung and spleen tissue from patients who died of sepsis revealed certain biochemical, cellular and histological findings that were consistent with immunosuppression, according to a study in the December 21 issue of JAMA.

NYUCI experts present latest research findings about hematologic cancers at 53rd ASH meeting

Experts from the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center, presented their latest research findings about hematologic cancers at the 53rd ASH Annual Meeting and Exposition held December 10-13, 2011 in San Diego, California.

Considering varying extent to which genes are turned on or off can help develop personalised, predictive medicines

The vast majority of genetic disorders (schizophrenia or breast cancer, for example) have different effects in different people. Moreover, an individual carrying certain mutations can develop a disease, whereas another one with the same mutations may not. This holds true even when comparing two identical twins who have identical genomes. But why does the same mutation have different effects in different individuals?

Study identifies ways to differentiate types of diabetes in young Asian Americans

Researchers at Joslin Diabetes Center have determined key differences between Type 1 and Type 2 diabetes in the Asian American population. This study, published today in PLoS ONE, identified ways to differentiate the types of diabetes, which can be clinically similar in young Asian Americans.

Researchers take a step toward neuronal replacement therapy

A new study has revealed that immature neurons taken from healthy mouse embryos can repair damaged brain circuitry and partially normalize metabolism when transplanted into adult mice that have grown morbidly obese due to a genetic deficiency.

MC3R gene plays an important role in maintaining steady weight

Against the backdrop of the growing epidemic of obesity in the United States, scientists from the Florida campus of The Scripps Research Institute have made an important new discovery regarding a specific gene that plays an important role in keeping a steady balance between our food intake and energy expenditure. The study may help scientists better understand the keys to fighting obesity and related disorders such as diabetes.
