The genome of diamondback moth provides new clues for sustainable pest management

January 13, 2013, Fujian and Shenzhen, China- An international research consortium, led by Fujian Agriculture, Forestry University (FAFU) and BGI, has completed the first genome sequence of the diamondback moth (DBM), the most destructive pest of brassica crops. This work provides wider insights into insect adaptation to host plant and opens new ways for more sustainable pest management. The latest study was published online today in Nature Genetics.

Foot soldiers of the immune system

Researchers at McGill University and the Research Center for Molecular Medicine (CeMM) of the Austrian Academy of Sciences have discovered the molecular blueprint behind the IFIT protein. This key protein enables the human immune system to detect viruses and prevent infection by acting as foot soldiers guarding the body against infection. They recognize foreign viral ribonucleic acid (RNA) produced by the virus and act as defender molecules by potentially latching onto the genome of the virus and preventing it from making copies of itself, blocking infection.

Identifying the molecular causes of vision loss in demyelinating disease

Demyelinating diseases, such as multiple sclerosis (MS), are frequently associated with the progressive loss of vision.

The retinal nerve damage is thought to be caused by immune system-mediated inflammation; however, other demyelinating disorders, such as Pelizaeus-Merzbacher disease, do not involve the immune system, suggesting that there are other causes of retinal nerve damage.

ELF5 transcription factor could influence future breast cancer treatment

Australian scientists have shown in the laboratory how a transcription factor causes breast cancer cells to develop an aggressive subtype that lacks sensitivity to estrogen and does not respond to known anti-estrogen therapies. The research, which has significant implications for breast cancer treatment, is published December 27 in the open access journal PLOS Biology.

Bacterial imbalance contributes to intestinal inflammation and carcinogenesis

Instability in the composition of gut bacterial communities (dysbiosis) has been linked to common human intestinal disorders, including inflammatory bowel disease and colorectal cancer; however, it is unclear if dysbiosis can instigate disease or if it is a consequence of the underlying disorder.

In this issue of the Journal of Clinical Investigation, researchers led by Mathias Chamaillard at the University Lille Nord de France in Lille, France, examined intestinal inflammation and tumorigenesis in a mouse model of dysbiosis.

New fusion gene contributes to glioblastoma progression

Fusion genes are common chromosomal aberrations in many cancers, and can be used as prognostic markers and drug targets in clinical practice.

In this issue of the Journal of Clinical Investigation, researchers led by Matti Annala at Tampere University of Technology in Finland identified a fusion between the FGFR3 and TACC3 genes in human glioblastoma samples.

The protein produced by this fusion gene promoted tumor growth and progression in a mouse model of glioblastoma, while increased expression of either of the normal genes did not alter tumor progression.

A new treatment for kidney disease-associated heart failure?

Chronic kidney disease (CKD) patients frequently suffer from mineral bone disorder, which causes vascular calcification and, eventually, chronic heart failure.

Similar to patients with CKD, mice with low levels of the protein klotho (klotho hypomorphic mice) also develop vascular calcification and have shorter life spans compared to normal mice.

Small peptide ameliorates autoimmune skin blistering disease in mice

Pemphigus vulgaris is a life-threatening autoimmune skin disease that is occurs when the body's immune system generates antibodies that target proteins in the skin known as desomogleins.

Desmogleins help to form the adhesive bonds that hold skin cells together and keep the skin intact. Currently, pemphigus vulgaris is treated by long-term immune suppression; however, this can leave the patient susceptible to infection.

To protect against injuries, young athletes may need to play more just for fun

MAYWOOD, Il. - One way to avoid injuries in young athletes may be for them to simply spend more time in unorganized free play such as pick-up games, a Loyola University Medical Study has found.

In a first-of-its-kind study, sports medicine specialist Dr. Neeru Jayanthi and colleagues found that injured young athletes who play a single sport such as tennis spent much less time in free play and unorganized sports than uninjured athletes who play tennis and many other sports.

Game-based economics research explains why we roll the dice on flu shots

With 41 states having reported widespread and severe outbreaks of flu this season, timely new research sheds light on why less than half of the American population has gotten a flu shot.

Despite widespread knowledge that a vaccine is the best way to reduce the chances of catching and spreading the flu, even three of the four main TODAY show anchors recently admitted they had not gotten a flu shot (until they did so live on the air).

Lady beetle diet influences its effectiveness as biocontrol agent

This press release is available in Spanish.

By examining what lady beetles eat, U.S. Department of Agriculture (USDA) scientists are learning more about the movement of these beneficial insects in farm fields—and whether they'll actively feed on crop pests.

Herbal treatments for postmenopausal symptoms can be recommended as an alternative to HRT

Herbal and complementary medicines could be recommended as an alternative to hormone replacement therapy (HRT) for treating postmenopausal symptoms says a new review published today in The Obstetrician and Gynaecologist (TOG).

The review outlines the advantages and limitations of both pharmacological and herbal and complementary treatments for women with postmenopausal symptoms.

American Cancer Society recommends informed decision making in lung cancer screening

ATLANTA –January 11, 2013—New guidelines from the American Cancer Society say evidence is sufficient to recommend screening high risk patients for lung cancer with low-dose computed tomography (CT) provided that certain conditions exist:

Researchers use iPSCs to define optimal treatment for managing life-threatening arrhythmias

Researchers used induced pluripotent stem cells (iPSCs) derived from a young patient with Long QT syndrome (LQTS), a congenital heart disorder, to determine a course of treatment that helped manage the patient's life-threatening arrhythmias. The results, which appear in The Journal of General Physiology, could lead to improved treatments for LQTS and other channelopathies, diseases caused by disturbed ion channel function.

New treatment could combat deadly chemical agents

An enzyme treatment which could neutralise the effects of lethal chemicals responsible for the deaths of hundreds of thousands of people across the world has been developed by experts at the University of Sheffield.

Organophosphorus agents (OP) are used as pesticides in developing countries and acute poisoning is common because of insufficient control, poor storage, ready availability, and inadequate education amongst farmers.
