The research has the potential to lead to a simple screening system for developing new d...

Study provides insights on why some prostate cancer becomes resistant to hormone withdrawl therapy

...fter hormone deprivation, but in most cases, it is believed that a small percentage of the tumor cells become resistant. Eventually, these resistant cells grow to become the predominant cancer, and no successful therapies have yet been developed for men with the hormone-withdrawal-resistant form of the diseas...

The earliest human colonizers are believed to have arrived in Australia by sea from Indonesia about 50,000 years ago, using fire as a tool to hunt, clear paths, signal each other and promote the growth of certain plants, he said.

Those experiments hinted that one important steroid-related gene coded for a receptor protein called BRI1 that bound to the cell membrane. Their experiments indicated that another protein, a kinase call...

...some, called Y, was not explored because it is not believed to contain many genes. Identical stretches of DNA on three chromosomes -- chromosomes 7, 8 and 10 -- were found to be shared in about 60 percent of the gay brothers in the study, compared to about 50 percent expected by chance. The region on chromos...

National survey shows Americans are in the dark regarding genetically modified foods

...oods are out there; the majority (79%) incorrectly believed that GM tomatoes are available, possibly due to Calgene's highly publicized (but now defunct) GM tomato marketing effort in the mid 1990s. On a quiz about the basic science behind GM technology, 87 percent of Americans could not score a passing gra...

Gene therapy for Parkinson's disease moves forward in animals

...or glial cell line-derived neurotrophic factor, is believed to preserve brain cells and could provide protection against Parkinson's disease. But its use has been debated since trials in humans ended last year without showing clinical improvements. Amgen, the world's largest biotechnology company, conducted ...

Aird's laboratory will use the award in their continued investigations of the mechanisms that underlie differential gene expression within the endothelium and to gain a better u...

Scientists document complex genomic events leading to the birth of new genes

...RGP-family genes were identified, all of which are believed to be fully functional. To demonstrate that RGP-family genes have functions that are significantly divergent from those of RanBP2, Bork and his co-workers examined the subcellular localization of one of the RGP-family isoforms. In contrast to RanBP2...

Green tea extract shows promise as an anti-cancer agent, UCLA study finds

Without a reliable, non-invasive way to diagnose the disease, bladder cancer can be difficult to detect in the early, most treatable stages. When not found early, the tumors can be aggressive, and more than half of...
