How rat's genetic blueprint stacks up against those of mice and humans

An international research team, supported by the National Institutes of Health (NIH), today announced it has completed a high-quality, draft sequence of the genome of the laboratory rat, and has used that data to explore how the rat's genetic blueprint stacks up against those of mice and humans.

Scientists seek cause for what makes good cell go bad

Genetic mutations--sudden, random and usually harmful changes to the structure of a gene--are only one factor that determines the ultimate fate of a cell. Chicago scientists have discovered that a non-genetic molecular process also can play a role, and that experimenters can influence this process in bacteria, they report in the April 1 issue of the journal Nature.

Research team has found a new way to streamline gene isolation to determine their functions

A single strand of plant or animal DNA may contain tens of thousands of genes, each programmed to produce a specific protein essential for the growth or survival of the organism. The challenge for geneticists is to isolate individual genes and determine their function -- a painstaking process often requiring years of laboratory trial and error.

Heart disease can be reduced substantially by regularly treating existing gum infections

Reinforcing the relationship between periodontal disease and heart disease, oral biologists from the University at Buffalo have shown that levels of two inflammatory proteins known to raise the risk of heart disease can be reduced substantially by regularly treating existing gum infections.

Discovery of gender difference in cartilage cells may help spinal disc repair

When biologist Barbara Boyan discovered science’s first proof of biochemical differences between male and female cartilage cells, she began to question the approaches she and other researchers were taking to study cells. Was their thinking biologically relevant?

Natural compound in snake venom for treatment of malignant tumours

Researchers at the University of South Australia have made a major discovery using a natural compound in snake venom that shows very promising anti-cancer effects. The compound works by activating the destruction of cells which make up the blood vessels that supply nutrients to tumours, according to Associate Professor Tony Woods from UniSA’s School of Pharmaceutical, Molecular and Biomedical Sciences.

New research suggest that steroid treatment for osteoarthritis knee suffers may not progress disease as previously thought

Steroid treatment for osteoarthritis knee suffers was thought to progress the disease, but that belief has been overturned following a review of the literature by researchers at The University of Auckland. Associate-Professor Bruce Arroll, from the School of Population Health at the University, says that osteoarthritic knee pain is one of the leading causes of disability amongst older people.

Removal of thyroid glands may be unnecessary for most patients

An unpleasant postoperative procedure for thyroid cancer patients who have had their thyroid glands surgically removed may be unnecessary for most patients, according to Washington University researchers at Siteman Cancer Center and Barnes-Jewish Hospital in St. Louis.

Scientists find parallels between human speech and bird song which gives clues to human speech disorders.

The research by a team led by Stephanie White, UCLA assistant professor of physiological science, supports the theory that two genes shared by humans and songbirds, FoxP1 and FoxP2, may play a critical role in human speech, and speech disorders. The study is published March 31 in the Journal of Neuroscience.

Zebrafish show effects of ionizing and UV radiation differ during embryo development

Adam Dicker, M.D., Ph.D., associate professor of radiation oncology at Jefferson Medical College of Thomas Jefferson University and Jefferson’s Kimmel Cancer Center in Philadelphia, Mary Frances McAleer, M.D., Ph.D., a resident in the Department of Radiation Oncology at Jefferson Medical College and their co-workers compared the effects on zebrafish embryos of two types of radiation – ionizing radiation, which is the kind given to patients for cancer treatment, and ultraviolet (UV) radiation, which comes naturally from the sun.

Discovery of novel gene profile that may identify colon stem cells

Researchers at Jefferson Medical College have uncovered a novel pattern of gene expression in the stem cell-rich bottom of tiny “crypts” in the tissue lining the colon. By identifying these patterns, the scientists hope to be able to identify mechanisms through which stem cells contribute to the development of colon cancer.

£1.6m for research into a possible cure for muscular dystrophy

A consortium which includes Oxford researchers has won £1.6m in government funding for ground-breaking research into a possible cure for muscular dystrophy.

Human Genome Sciences can begin cardiovascular disease research

Human Genome Sciences, Inc.announced today that it has received a clinical development milestone payment from its partner, GlaxoSmithKline, related to the initiation of Phase 1 clinical trials of 677116 for the treatment of cardiovascular disease. 677116 is a small-molecule inhibitor of lipoprotein-associated phospholipase A2 (Lp-PLA2), an enzyme associated with the formation of atherosclerotic plaques.

Extraction of RNA from Archived Formalin-Fixed, Paraffin-Embedded Tissue

For the first time, Fox Chase Cancer Center researchers have demonstrated the ability to extract RNA from formalin-fixed, paraffin-embedded tissue samples archived for up to five years. What's more, the technology used retrieves high-quality samples, allowing researchers to identify cancer-related genetic changes. Accepted as a "late-breaking" abstract, the research was presented today at the 95th Annual Meeting of the American Association for Cancer Research by Renata Coudry, M.D., a research pathologist at Fox Chase Cancer Center.

New storage method amplifies cells available for science

Like many other kinds of cells used in biomedical research, human embryonic stem cells are stored and transported in a cryopreserved state, frozen to -320 degrees Fahrenheit, the temperature of their liquid nitrogen storage bath. But when scientists thaw the cells for use in the lab, less than 1 percent awake from their frigid slumber and assume their undifferentiated state. This 'blank slate' form is characteristic of stem cells and essential for the basic science required before the promising cells are ready for the clinic.

Alzheimer’s Association asks for $40 million in additional funding

The Alzheimer’s Association today called on the House of Representatives to provide $40 million in additional funding this year to the National Institutes of Health NIH) to support large-scale clinical trials for treatments that would slow or delay the progression of Alzheimer’s disease.

75% of young Britains still ignoring skin cancer warnings

Almost three quarters of Britain's young men and women are boosting their risk of potentially fatal skin cancer in their search for a suntan. A specially commissioned survey for Cancer Research UK today reveals that 70 per cent of 16 to 24 year olds still want a tan on holiday despite warnings of over exposure to the sun.

Cancer research boosted in Queensland Australia

The University of Queensland's Institute for Molecular Bioscience (IMB) is one of just three recipients of the largest research grant ever given by the Australian Cancer Research Foundation (ACRF).

Air pollution effects Cystic Fibrosis Sufferers

University of Washington (UW) researchers have shown for the first time that air pollution has adverse effects on people with cystic fibrosis (CF). The research results are published in the April 1 edition of the American Journal of Respiratory and Critical Care Medicine.

New research to predict patient response to cancer chemotherapies

Timothy J. Yeatman, M.D., Moffitt's Associate Center Director for Clinical Investigations at the H. Lee Moffitt Cancer Center & Research Institute, and the Sarasota-based DNAPrintTM genomics, Inc., have formed a joint research program to develop and implement new clinical tests for predicting patient response to cancer chemotherapies.
