Scientists review damage-control in metabolism

In this week's issue of the prestigious journal Nature Chemical Biology, scientists Carole Linster (University of Luxembourg), Emile Van Schaftingen (Louvain University), and Andrew D. Hanson (University of Florida, Gainesville) review an important, but so far neglected, part of metabolism, namely metabolite damage-control.

Researchers identify mechanism by which vancomycin resistance spreads between bacteria

Worldwide, many strains of the bacterium Staphyloccocus aureus, commonly known as staph infections, are already resistant to all antibiotics except vancomycin. But as bacteria are becoming resistant to this once powerful antidote, S. aureus has moved one step closer to becoming an unstoppable killer.

Enzymes may have new role as intelligent micro and nanomotors

Enzymes, workhorse molecules of life that underpin almost every biological process, may have a new role as "intelligent" micro- and nanomotors with applications in medicine, engineering and other fields.

FDA approves Genzyme’s KYNAMRO to treat homozygous familial hypercholesterolemia

Genzyme, a Sanofi company, and Isis Pharmaceuticals Inc., today announced that the U.S. Food and Drug Administration (FDA) has approved its New Drug Application (NDA) for KYNAMROTM (mipomersen sodium) injection.

SOD1 enzyme protects cells by regulating cell energy and metabolism

Just like a comic book super hero, you could say that the enzyme superoxide dismutase (SOD1) has a secret identity. Since its discovery in 1969, scientists believed SOD1's only role was to protect living cells against damage from free radicals. Now, researchers at the Johns Hopkins Bloomberg School of Public Health have discovered that SOD1 protects cells by regulating cell energy and metabolism. The results of their research were published January 17, 2013, in the journal Cell.

Phenformin decreases size of lung tumors and increases survival in mice

Ever since discovering a decade ago that a gene altered in lung cancer regulated an enzyme used in therapies against diabetes, Reuben Shaw has wondered if drugs originally designed to treat metabolic diseases could also work against cancer.

Genzyme receives FDA approval for Kynamro to treat homozygous familial hypercholesterolemia

The U.S. Food and Drug Administration today approved Kynamro (mipomersen sodium) injection as an addition to lipid-lowering medications and diet to treat patients with a rare type of high cholesterol called homozygous familial hypercholesterolemia (HoFH).

Dectin-1 potential target for nasal polyposis

The transmembrane protein Dectin-1 appears to play a role in the pathogenesis of nasal polyposis, providing a potential new target for treating the condition, report Chinese researchers.

Scientists identify genetic process in which normal liver cells transform into cancerous ones

A team of scientists from the Cancer Science Institute of Singapore (CSI) at the National University of Singapore (NUS) has identified a genetic process in which normal liver cells transform into cancerous ones. The finding provides new understanding into the pathogenesis of human cancers.

Blue light can selectively eradicate skin and soft tissue infections

Blue light can selectively eradicate Pseudomonas aeruginosa infections of the skin and soft tissues, while preserving the outermost layer of skin, according to a proof-of-principle study led by Michael R. Hamblin of the Massachusetts General Hospital, and the Harvard Medical School, Boston.

LOX enzyme can create scarred microenvironment that enhances cancer spreading

What to fear most if faced by a cancer diagnosis is the spread of the cancer to other parts of the body. This process called metastasis accounts for over 90% of cancer patient deaths and therefore is a strong focus for cancer researchers.

TSRI scientists to identify, test and develop drug candidates for several neurodegenerative disorders

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have been awarded approximately $1.2 million from the U.S. National Institute of General Medical Sciences of the National Institutes of Health to identify, test and develop a series of drug candidates for a number of diseases, including rheumatoid arthritis, heart disease and several neurodegenerative disorders.

IRHOM2-targeted drugs can effectively treat patients with rheumatoid arthritis

Researchers at Hospital for Special Surgery have identified a potential new target for drugs to treat patients with rheumatoid arthritis (RA), a protein known as IRHOM2. The finding could provide an effective and potentially less toxic alternative therapy to tumor necrosis factor-alpha blockers (TNF-blockers), the mainstay of treatment for rheumatoid arthritis, and could help patients who do not respond to this treatment. Efforts to develop drugs that hone in on this new target are underway.

Telomerase gene mutation immortalizes deadly skin cancer

About ten percent of all cases of malignant melanoma are familial cases. The genome of affected families tells scientists a lot about how the disease develops. Prof. Dr. Rajiv Kumar of the German Cancer Research Center together with Prof. Dr. Dirk Schadendorf from Essen University Hospital studied a family where 14 family members were affected by malignant melanoma.
