Gene silencing technique offers new strategy for treating, curing disease

...tated genes lead to malfunctioning proteins, which cause disease. The information in a gene is not directly converted into proteins, but first is copied by special enzymes into many copies of messenger RNA, which then move out of the nucleus and into the body of the cell, where they go on to create a prot...

Study of energy and health in Africa focuses spotlight on charcoal and forest management

... 2030, smoke from wood fires used for cooking will cause about 10 million premature deaths among women and children in Africa. By 2050, according to the report, smoke from cooking fires will release about 7 billion tons of carbon in the form of greenhouse gases to the environment. That's about 6 percent of...

According to the Centers for Disease Control and Prevention, approximately 1.25 million Americans are chronically infected with the HBV virus. Baraclude s...

High-powered gene profiles provide clues to genes involved in common form of lung cancer

...r the basic biology of lung cancer, the number one cause of cancer-related deaths in the United States. Non-small cell lung cancer (NSCLC) accounts for about 75 percent of all lung cancers and is responsible for nearly 120,000 deaths in this country annually. It is one of the most difficult cancers to trea...

Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine

...e University of Chicago show how the bacteria that cause the plague manage to outsmart the immune system and how, by slightly altering one of the microbe's tools, the researchers produced what may be the first safe and effective vaccine. Both papers -- one published online July 28 in Science Express and o...

Immune system's distress signal tells bacteria when to strike back

... causing gut-derived sepsis. It is also a frequent cause of infections after major surgery. Physicians have theorized, said Alverdy, that germs such as Pseudomonas are always "probing for a weakness in the host and are ready and willing to strike whenever they find one." He and his colleagues, however, ar...

This time, though, when we tested mice with an activated Ras gene, but an absent DGK iota gene, the number of tumors was significantly reduced," Topham says. "This result is inte...

Mosaic mouse technique offers a powerful new tool to study diseases and genetics
