Scientists identify genetic element that the dengue virus uses to replicate

The first step in the transmission of mosquito-borne viruses is no mystery: it's the pesky insect's bite that allows the virus to enter its victim's bloodstream.

Centrosomes may contain ribonucleic acid

Despite more than a century of study, scientists know relatively little about the inner workings of centrosomes - organelles essential to cell division in humans and animals.

Prefrontal cortex in the brain damaged by both alcoholism and chronic smoking

Alcoholism is commonly associated with chronic smoking, and both alcohol and nicotine are believed to act on the same brain region. Research builds upon previous research that identified four potential alcohol-sensitive genes in the prefrontal cortex, finding that smoking also influences the expression of these genes.

Weill Cornell experts publish review of genetic medicine

In an article published in the April issue of Nature Reviews Genetics, two experts at the Weill Medical College of Cornell University sum up the achievements, challenges and promise of a burgeoning field: genetic medicine.

Study on fruit flies offers new approach to understand human response to viral infections

A research team led by UC Riverside scientists has shown that the common fruit fly can serve as an excellent model for studying the immunity animals are born with for fighting viral infections.

Cells have a natural defense against HIV

Scientists here have discovered a previously unknown mechanism that cells use to fight off the human immunodeficiency virus (HIV), the cause of AIDS.

Polyphosphate speeds blood clotting and helps clots last longer

A serendipitous comparison prompted by an old scientific image and involving an ancient but understudied molecule may lead to a new treatment strategy for injuries or illnesses in which blood clotting is paramount to survival.

Scientists discover how HIV infects healthy cells

Using sophisticated detection methods, researchers at the Saint Louis University Institute for Molecular Virology (IMV) have demonstrated the molecular mechanism by which the HIV virus infects, or integrates, healthy cells. The discovery could lead to new drug treatments for HIV.

University at Buffalo researches rules for targeting RNA

Once described as DNA's less-famous chemical cousin, RNA, or ribonucleic acid, recently has moved to center stage.

New high-resolution data on intact ribosome

A new, sharper picture of the nano-machine that translates our genetic program into proteins promises to help researchers explain how some types of antibiotics work and could lead to the design of better ones.

RNA dynamics may help in drug design

Biophysicists have developed a method for studying, in real time, a nanoscale "docking and undocking" interaction between small pieces of ribonucleic acid (RNA), a technique that may be broadly useful in studying structural changes in RNA that affect its function.

New understanding of microRNAs

Ribonucleic acid, or RNA, has long been thought to be important only to translate a gene's DNA into the proteins that are cells' workhorses. But new evidence shows that tiny bits of RNA not used to make proteins actually play central roles in normal biology and in the development of cancers.

2.5 million euros helps fight liver cancer

The overall project will concentrate on three areas where Europe is in a relatively favourable position compared with the US - human tissue resources, ribonucleic acid (RNA) technology, and structural proteomics. However, the initial focus will be on the development of genomics targets in hepatocellular carcinoma (HCC) or liver cancer as it is one of the leading causes of cancer death worldwide and has a very poor prognosis.

New technique to identify fetal genetic material from amniotic fluid

A preliminary report suggests that cell-free fetal messenger RNA (ribonucleic acid) can be extracted from amniotic fluid (fluid around the fetus), and then be analyzed to study gene expression changes that may reflect the well-being of the fetus, according to a paper in the February 16 issue of JAMA, a theme issue on medical applications of biotechnology.

Electrochemical DNA chip that is able to detect DNA at very low concentrations

Toshiba Corporation has announced the development of a highly sensitive electrochemical DNA chip that is able to detect DNA at very low concentrations, a capability that will support advances in gene detection and analysis for individual treatment regimes, and the monitoring of healthy individuals for any predisposition to certain diseases.

Discovery of naturally occurring RNA "switches" that manage the amino acid glycine

Two University of Washington computer scientists are part of a team that has discovered a pair of rare, naturally occurring RNA "switches" in a class of bacteria that work cooperatively to manage the amino acid glycine.

Researchers have coaxed RNA to self-assemble into 3-D arrays

These RNA structures can form a wider variety of shapes than double-stranded DNA can and are easier to manipulate than many protein alternatives.

Nucleic acid-amplification testing has improved the safety of the nation's blood supply

State-of-the-art testing systems to screen donated blood have improved the safety of the nation's blood supply by preventing the transmission of potentially deadly viruses, according to a new study funded by the National Heart, Lung, and Blood Institute.

Microscopic scaffolding to house the tiny components of nanotech devices could be built from RNA

Microscopic scaffolding to house the tiny components of nanotech devices could be built from RNA, the same substance that shuttles messages around a cell's nucleus, reports a Purdue University research group.

New gene-silencing technique

A new gene-silencing technique that takes place in the nucleus of human cells, has been demonstrated by researchers at the University of California, San Diego (UCSD) School of Medicine and the VA San Diego Healthcare System.
