Plexxikon announces promising preclinical data of PLX3397

Plexxikon Inc. today announced promising preclinical data from in vivo Alzheimer's Disease studies demonstrating a dramatic reduction in activated microglia in the brains of very old (22 months) 3xTG-AD mice, a triple transgenic model for Alzheimer's Disease. This reduction of activated microglia led to significantly improved learning in the treated group.

Report on new, automated genetic method for determining blood types appears in Analytical Chemistry

Scientists are reporting an advance toward enabling more blood banks to adopt so-called "extended blood group typing," which increases transfusion safety by better matching donors and recipients. Their report on a new, automated genetic method for determining a broader range of blood types appears in ACS' Analytical Chemistry, a semi-monthly journal.

Medical standard of care triggers biological responses in brain that can fuel tumor cell survival: Researchers

The medical standard of care - comprised of surgery, radiation and chemotherapy - for the most common form of brain cancer triggers a number of biological responses that may actually feed the energy metabolism that supports the disease, according to Boston College researchers writing in the journal Lancet Oncology.

New use of green fluorescent protein

Scientists are reporting discovery of a way to help proteins such as the new generation of protein-based drugs -- sometimes heralded as tomorrow's potential "miracle cures" -- get past the biochemical "Entrance Forbidden" barrier that keeps them from entering cells and doing their work. The new technique, described in the monthly journal, ACS Chemical Biology, represents a new use for an engineered form of green fluorescent protein, the topic of the 2008 Nobel Prize in Chemistry that is one of the most important research tools in biosciences.

NIH announces 5 more years of funding for Consortium of Food Allergy Research

Today, the National Institutes of Health announce that the Consortium of Food Allergy Research (CoFAR), established in 2005, will be funded for five more years. CoFAR will continue to foster new approaches to prevent and treat food allergies and also expand in scope to include research on the genetic causes underlying food allergy and studies of food allergy-associated eosinophilic gastrointestinal diseases (EGIDs).

Implantable artificial salivary gland to be developed for Xerostomia patients

The goal of this research was to create an ECM modified hyaluronic acid (HA) based hydrogel culture system that allows for the growth and differentiation of salivary acinar cells into functional acini-like structures capable of secreting large amounts of protein and fluid unidirectionally. Xerostomia, a condition resulting from irradiation of the head and neck, affects more than 40,000 cancer patients each year in the United States. According to this research, these patients will greatly benefit from the development of a functional implantable artificial salivary gland.

Enzyme mTOR regulates autophagy: Study

Cells that consume parts of themselves can stop this process autonomously as well. This was discovered by NWO researcher Judith Klumperman's group, in collaboration with colleagues from the National Institute of Health in Washington. The self-cannibalism is part of the normal digestive process of the cell, but also a survival mechanism in times of famine. This is what makes it difficult for doctors to 'starve out' cancer cells, for instance. The research results were published on 6 June in Nature.

Key protein in insulin signaling pathway adds insights into development, aging

What makes a bee grow up to be a queen? Scientists have long pondered this mystery. Now, researchers in the School of Life Sciences at Arizona State University have fit a new piece into the puzzle of bee development. Their work not only adds to understanding about bees, but also adds insights into our own development and aging.

Study reveals anti-diabetic properties of cashew seed extract

Cashew seed extract shows promise as an effective anti-diabetic, according to a new study from the University of Montreal (Canada) and the Universit- de Yaound- (Cameroun). Published in the journal Molecular Nutrition & Food Research, the investigation analyzed the reputed health benefits of cashew tree products on diabetes, notably whether cashew extracts could improve the body's response to its own insulin.

Keck School of Medicine receives grant for research on biomarker impact on breast cancer screening

Researchers at the Keck School of Medicine of the University of Southern California (USC) will test whether a set of blood-based biomarkers can assist mammography in the early detection of breast cancer with a $180,000 grant announced today from Susan G. Komen for the Cure®. The grant will fund research into whether specific biomarkers, or minute substances in the blood, can effectively distinguish breast cancer patients from their healthy counterparts and whether an inexpensive, less invasive screening strategy can be developed based on this approach.

JNK protein controls cell cycle, new study reveals

Put simply, a tumor is the result of out-of-control cell growth. To assure that the cell cycle - the cell's process of duplicating itself to make more cells - goes smoothly, a large network of proteins tells other proteins what to do and when to do it. When any of these layers of protein regulation fail, cell growth can get out of hand. A new study led by Ze'ev Ronai, Ph.D., associate director of Sanford-Burnham's National Cancer Institute-designated Cancer Center, reveals a new player in cell cycle control.

Study links high-fat diet as potential cause of prostatic diseases

Prostate cancer is the second leading cause of cancer-related deaths in men with an estimated 192,280 new cases diagnosed in the US in 2009 (Jemal 2009). Diet is considered one of the most important controllable risk factors for inflammation and prostate diseases including benign prostatic hyperplsia, prostatitis, and prostate cancer.

SWCRF/Emerald Foundation Global Collaborative Grant to fund critical cancer research

The leukemia stem cell-the root cause of all acute leukemias- represents a small population of cells in patients that are difficult to eliminate with standard treatments available today. Though current chemotherapy can produce temporary remission in leukemia survivors, they remain at risk of experiencing a recurrence and dying from the disease.
