Protein mutated in cancer found to be linked to diabetes

A study published by Nature has defined the function of p110 alpha, the flag-ship molecule of the eight member PI3K family, which is one of the most frequently activated pathways in cancer. The function of p110 alpha in the body has eluded researchers for over a decade but a new approach to generating mouse models, has allowed investigators to solve the mystery and yield important information for planned clinical trials with PI3K inhibitors.

Placental growth factor may help body repair heart attack damage

Heart attack patients produce higher levels of a natural substance in the body that plays a role in the growth of new blood vessels and this over-expression of placental growth factor (PlGF) may help reduce damage to the heart muscle

Researchers suggest drug could block metastasis or reduce pain for bone cancer patients

An international research team has identified what may be a critical molecule in the ability of tumours to metastasize -- or spread -- into bone.

Cholesterol-lowering drug might not promote healthy hearts

Antioxidants, such as beta-carotene and Vitamin E, have been touted for their ability to protect against heart disease.

Researchers determine factors that turn on protein production in bacteria

In the study, published in the journal Molecular Cell, researchers Sean Studer and Simpson Joseph in UCSD's Department of Chemistry and Biochemistry report how the messenger RNA instructions to make a protein are unfolded in a bacterial cell, so that they can be read by the cell's protein-making machinery.

Research explains why recipients of growth hormone therapy may develop colon polyps

The use of growth hormone therapy has been linked in some people to the development of colon polyps, a possible precursor to colorectal cancer - but medical researchers have debated the extent of a cancer risk.

DNA "dark state" findings help explain evolution of life

Chemists at Oregon State University have pioneered a controversial theory about how supposedly-stable DNA bases can be pushed into a "dark state" in which they are highly vulnerable to damage from ultraviolet radiation - an idea that has challenged some of the most basic concepts of modern biochemistry.

Targeted mutations in mice uncover two key molecular events linked to learning

Johns Hopkins researchers have used mouse mutants to define critical steps involved in learning basic motor skills. The study focuses on the behavior of two proteins and the specific steps they take to control a neuron's ability to learn by adapting to signals from other nerve cells.

Losartan can prevent progression of Marfan syndrome

A commonly prescribed blood pressure medication may provide the first ray of hope in preventing potentially deadly complications of Marfan syndrome, a genetic disease that weakens the structural meshwork of blood vessels.

Researchers identify critical human cell surface molecule involved in infection by Kaposi's sarcoma herpesvirus

Researchers at the National Institute of Allergy and Infectious Disease (NIAID) have identified a critical human cell surface molecule involved in infection by Kaposi's sarcoma herpesvirus (KSHV), the virus that causes Kaposi's sarcoma and certain forms of lymphoma.

Colorimetric screening detects DNA, small molecules and proteins

Using the unusual color properties of gold at the nanoscale, scientists at Northwestern University have developed a "litmus test" for DNA and small molecule binding that eventually could be used by pharmaceutical companies to rapidly identify promising candidates for new anti-cancer drugs.

New discovery could help improve some forms of chemotherapy

The research looked at XPB helicase from an archaea, a single cell organism similar to bacteria. Helicases are enzymes that unwind or separate the strands of the nucleic acid double helix, an action that is critical to transcription and nucleotide excision repair (NER), as well as other cell processes.

Researchers improve Botox treatment

There may soon be a better way to fight unsightly wrinkles. Researchers have discovered a novel way to increase the potency of botulinum neurotoxin treatments - commonly known as Botox - that they say could one day allow patients to receive the injections less frequently while maintaining or even enhancing its cosmetic benefits.

Researchers identify internal electron transfer mechanism of cell respiration

Researchers at the Institute of Biotechnology of the University of Helsinki have for the first time identified an internal electron transfer reaction that initiates the proton pump mechanism of the respiratory enzyme.

Researchers identify potential targets for more effective analgesic drugs with potentially fewer side effects

Studying mice, pain researchers at Washington University School of Medicine in St. Louis have identified two key components in the pain cascade that may provide targets for more effective analgesic drugs with potentially fewer side effects

Vitamin C in the blood stream is directly related to fat oxidation

Nutrition researchers from Arizona State University report that the amount of vitamin C in the blood stream is directly related to fat oxidation - the body's ability to use fat as a fuel source - during both exercise and at rest.

International team tackle protein folding

A team of researchers from EPFL, (Ecole Polytechnique Fidirale de Lausanne), the University of Lausanne, Northwestern University and Tel Aviv Universitybring biology and statistical physics together to answer the question of how molecular chaperones fold, unfold and pull proteins around in the cell.

Study provides important insights into how different modes of training reduce muscle injury

If you're a mouse, then stretching before you exercise is a good thing - even as long as two weeks before your next cheese hunt or cat run. But if you're reading this for yourself, it's a bit more complicated.
