Scientists discover how androgen plays a role in the development of prostate cancer

Scientists have discovered for the first time a specific biochemical pathway by which the sex hormone, androgen, increases levels of harmful chemicals called reactive oxygen species (ROS) in the prostate gland that play a role in the development of prostate cancer.

New smart anti-microbial approach to preventing tooth decay

Preventing cavities could one day involve the dental equivalent of a military surgical strike. A team of researchers supported by the National Institute of Dental and Craniofacial Research report they have created a new smart anti-microbial treatment that can be chemically programmed in the laboratory to seek out and kill a specific cavity-causing species of bacteria, leaving the good bacteria untouched.

Study indicates how drug efficacy can be increased by manipulating the signalling mechanism

Researchers believe they have found a way to change the action of 60 percent of currently available medications, in some cases making them many times more effective, according to an article published in the April 21 edition of the journal Science. The discovery has the potential to improve treatments for diseases including heart disease, cancer, diabetes, depression and arthritis. The study describes a new way to manipulate perhaps the most important signaling mechanism in human cells: G-protein coupled receptors (GPCRs).

New technique to speed discovery of drug targets in chemical genetics

Researchers at Fox Chase Cancer Center have developed a new technique to speed discovery of drug targets in chemical genetics. Fox Chase researcher Jeffrey R. Peterson, Ph.D., and his colleagues describe a new way to swiftly find the proteins targeted by small molecule inhibitors during high-throughput screening (HTS) experiments. The new work offers a critical solution to a common stumbling block in this booming field of drug discovery.
