New library for development of targeted cancer drugs

In a technical tour de force, scientists at Fox Chase Cancer Center have cataloged and cross-indexed the actions of 178 candidate drugs capable of blocking the activity of one or more of 300 enzymes, including enzymes critical for cancer and other diseases. Additionally, a free library of the results has been made available online to the research community. This unique library represents an important new tool for accelerating the development of an entire class of targeted cancer drugs.

Researchers identify FMRP protein as key player in RNA editing

The most common form of heritable cognitive impairment is Fragile X Syndrome, caused by mutation or malfunction of the FMR1 gene. Loss of FMR1 function is also the most common genetic cause of autism. Understanding how this gene works is vital to finding new treatments to help Fragile X patients and others.

Oral hormonal contraceptives linked to blood clots: Study

A new study has shown that women who use new type of contraceptive pills are twice as likely to develop life threatening blood clots as those who take older versions. Oral hormonal contraceptives have been known to increase the risk of a blood clot in deep leg veins, known as venous thromboembolism (VTE). These can prove fatal if they travel to the lungs. But, researchers at the University of Copenhagen, Denmark, found the “third-generation” pills are doubly harmful than the older versions.
