Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

Study reveals dual role for Norrin/Frizzled-4 protein pair

Working with mice, Johns Hopkins researchers have shed light on the activity of a protein pair found in cells that form the walls of blood vessels in the brain and retina, experiments that could lead to therapeutic control of the blood-brain barrier and of blood vessel growth in the eye.

Cocktail-treated human NK cells show promise against cancer

Fighting cancer using the body's own defense system is a promising treatment approach. Immune therapies have even become clinical routine in treating a few cancers such as malignant melanoma and prostate cancer. Natural killer cells (or NK cells) are considered to be particularly suitable weapons against cancer.

Scientists isolate previously unknown protein in skeletal muscle

Scientists at Dana-Farber Cancer Institute have isolated a previously unknown protein in muscles that spurs their growth and increased power following resistance exercise. They suggest that artificially raising the protein's levels might someday help prevent muscle loss caused by cancer, prolonged inactivity in hospital patients, and aging.

Bio-Path to initiate BP-100-1.01 Phase I trial for treatment of two types of breast cancer

Bio-Path Holdings, Inc., a biotechnology company developing a liposomal delivery technology for nucleic acid cancer drugs, today announced it is initiating development of its lead cancer drug BP-100-1.01 (Liposomal Grb-2) to treat triple negative breast cancer (TNBC) and inflammatory breast cancer (IBC), two cancers characterized by formation of aggressive tumors and relatively high mortality rates.

Combination of PD-991 and letrozole improves survival in patients with HER2- breast cancer

Pfizer Inc. today announced randomized Phase 2 data that showed PD-0332991 (PD-991) in combination with letrozole significantly extended progression free survival (PFS) compared with letrozole alone in post-menopausal patients with estrogen receptor positive (ER+), human epidermal growth factor receptor 2 negative (HER2-) locally advanced or metastatic breast cancer.

Investigators describe process by which apoE4 protein promotes development of Alzheimer's

Despite researchers' best efforts, no drug exists that can slow, halt or reverse the onslaught of Alzheimer's disease. A progressive and fatal neurodegenerative disorder, Alzheimer's has stolen the memories and livelihoods of millions-leaving patients and their families struggling to cope with the disease's devastating consequences. But today, scientists at the Gladstone Institutes propose a new research avenue that has the potential to change all that.

Bayer submits MAA in Europe for EYLEA to treat macular edema after CRVO

Regeneron Pharmaceuticals, Inc. and Bayer HealthCare today announced that Bayer HealthCare has submitted an application for marketing authorization in Europe for EYLEA (aflibercept) Injection for the treatment of macular edema following Central Retinal Vein Occlusion (CRVO).

Scientists evaluate two different strategies to treat Usher syndrome

After years of basic research, scientists at Johannes Gutenberg University Mainz (JGU) are increasingly able to understand the mechanisms underlying the human Usher syndrome and are coming ever closer to finding a successful treatment approach. The scientists in the Usher research group of Professor Dr. Uwe Wolfrum are evaluating two different strategies. These involve either the repair of mutated genes or the deactivation of the genetic defects using agents.

ASU scientists use X-ray laser to reveal 3-D structure of cathepsin B enzyme

An international team of scientists, using the world's most powerful X-ray laser, has revealed the three dimensional structure of a key enzyme that enables the single-celled parasite that causes African trypanosomiasis (or sleeping sickness) in humans.

Scientists develop MitoFish for in vivo studies of mitochondria transport in nerve cells

Scientists have demonstrated a new way to investigate mechanisms at work in Alzheimer's and other neurodegenerative diseases, which also could prove useful in the search for effective drugs. For new insights, they turned to the zebrafish, which is transparent in the early stages of its life. The researchers developed a transgenic variety, the "MitoFish," that enables them to see - within individual neurons of living animals - how brain diseases disturb the transport of mitochondria, the power plants of the cell.

Tyk2 enzyme helps regulate obesity through differentiation of brown adipose tissue

Approximately 68 percent of U.S. adults are overweight or obese, according to the National Cancer Institute, which puts them at greater risk for developing cancer, cardiovascular disease, diabetes and a host of other chronic illnesses. But an international team of scientists led by Virginia Commonwealth University Massey Cancer Center researcher Andrew Larner, M.D., Ph.D., has successfully reversed obesity in mice by manipulating the production of an enzyme known as tyrosine-protein kinase-2 (Tyk2).

Paper reveals how 'kinase' is distributed across membranes

Using a super-resolution fluorescent microscope, Australian medical scientists are a step closer to understanding why and how human immune cells decide to activate or not, thus enabling or preventing disease taking hold in the body.

Combining 5-fluorouracil and IL-1 beta inhibitor can improve effectiveness of chemotherapy

These results reveal how the immune system can then limit the effectiveness of some cancer chemotherapies. The researchers now intend to block the molecules responsible for negative immune system activation to increase the efficiency of chemotherapy. A clinical trial to test this hypothesis should begin very soon.

Bioinformaticians use molecular simulations to explain specific step in HIV virion maturation

Bioinformaticians at IMIM (Hospital del Mar Medical Research Institute) and UPF (Pompeu Fabra University) have used molecular simulation techniques to explain a specific step in the maturation of the HIV virions, i.e., how newly formed inert virus particles become infectious, which is essential in understanding how the virus replicates.

Dietary fish oil supplements could help heal bedsores

Chock-full of Omega-3 fatty acids and antioxidants, fish oil can help lower blood pressure, reduce inflammation in the skin and joints, and promote healthy fetal development. Now a Tel Aviv University researcher has found that it has a positive effect on bedsores, too.
