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.

Scientists use tobacco plants to create antibodies against tumor cells

Scientists at Jefferson Medical College are using tobacco plants to produce monoclonal antibodies – tiny guided protein missiles – that can target and hunt down cancer cells. The plants promise to provide a cheaper, faster method of producing anticancer antibodies, raising hopes that the technology can one day be used in humans.

Researchers make new advances in determining the structure of all possible DNA sequences

Oregon State University researchers have made significant new advances in determining the structure of all possible DNA sequences – a discovery that in one sense takes up where Watson and Crick left off, after outlining in 1953 the double-helical structure of this biological blueprint for life.

Critical lock and key mechanism found for the assembly of tumor blood vessels

A critical lock and key mechanism that allows the final step in the completion of new blood vessel formation has been identified by a University of California, San Diego (UCSD) School of Medicine team in research that promises to lead to a new way to halt tumor growth by cutting off the tumor blood supply.

Research provides new insight into how individual genes control regeneration

Although they may look small and unassuming, planarian worms are famous in the scientific world for their extraordinary ability to regenerate body parts after injury. Even a small piece cut off a planarian can reorganize and regenerate to form a whole new worm.

Researchers determine mechanism of action of chemotherapy drug motexafin gadolinium

The chemotherapy drug motexafin gadolinium (brand name: Xcytrin, manufactured by Pharmacyclics, Inc.) works to thwart cancer cells by disrupting key enzymes involved in cellular metabolism, according to a team of researchers led by Joseph Hacia, Ph.D., assistant professor of biochemistry and molecular biology at the Keck School of Medicine of the University of Southern California.

Antibiotic minocycline might help alleviate HIV's negative effects on the brain and central nervous system

By studying animals, Johns Hopkins researchers have discovered that the antibiotic minocycline might help alleviate HIV's negative effects on the brain and central nervous system, problems that can develop even though antiretroviral therapy controls the virus elsewhere in the body.

Researchers show protein's role in stopping bacterial-induced inflammation

In findings that could have implications for autoimmune disorders and drug-resistant bacterial infections, researchers at the University of California, San Diego (UCSD) School of Medicine have identified a key protein involved in the appropriate shut-down of inflammation following an immune response to invading pathogens.

Antibiotics do not prevent heart attacks

Clinicians and researchers have found that more than three quarters of heart attack patients have been infected with chlamydia pneumoniae - a bacteria found in arteries of heart attack patients - and multiple studies have found this can double the risk of developing subsequent heart attacks.

Angiogenesis : Blocking tumor growth and treating infarction - a new target

Our tissues are able to form new blood vessels throughout life. This mechanism, which is called angiogenesis, is essential notably in the case of myocardial infarction, stroke and limb ischemia. The very same mechanism, however, keeps tumors supplied with nutrients and oxygen thus enabling them to continue growing.

Herceptin in combination with chemotherapy reduces risk of breast cancer recurrence in women with with early-stage breast cancer

Results from two clinical trials show that patients with early-stage breast cancer who received trastuzumab (Herceptin) in combination with chemotherapy had a 52 percent decrease in risk for breast cancer recurrence, compared with patients who received the same chemotherapy without the drug. The difference is statistically highly significant.
