Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

Study reveals how brain's immune system fights viral encephalitis

The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages - by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain.

Diabetes Busting Burgers!

Chemists with the U.S. Department of Agriculture recently presented a preliminary report to the 229th national meeting of the American Chemical Society, in which they say they have discovered a form of soluble cellulose that, if added to high-fat food. The new finding could soon benefit people who regularly eat fast-foods that are high in fat.

Most comprehensive genome-wide experimental analyses of sense-antisense transcripts to date

A team of scientists led by Dr. Kuniya Abe from the RIKEN BioResource Center in Japan has performed one of the most comprehensive genome-wide experimental analyses of sense-antisense transcripts to date. Their findings are published in the April issue of the journal Genome Research.

Gene therapy helps Lou Gehrig's disease

The most common form of motor neurone disease, called amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease, is caused when neurones in the spinal cord die, leading to muscle wasting and total paralysis.

New way of looking at MicroRNA and how it controls gene expression

A group of scientists at The Scripps Research Institute is reporting a discovery that sheds light on an area of research fundamental to everything from the normal processes that govern the everyday life of human cells to the aberrant mechanisms that underlie many diseases, including cancer and septic shock.

RNA interference as promising therapy for ALS

Scientists at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have used RNA interference in transgenic mice to silence a mutated gene that causes inherited cases of amytrophic lateral sclerosis (ALS), substantially delaying both the onset and the progression rate of the fatal motor neuron disease.

Telomerase finding has major implications for cancer

UCLA biochemists have determined the three-dimensional structure of a major domain of telomerase, the enzyme that helps maintain telomeres - small pieces of DNA on the ends of chromosomes that act as protective caps - allowing DNA ends to be copied completely when cells are replicated.

Finding may open new horizons for understanding the initiation of chemically induced cancers

A team from the chemistry and biology departments of New York University, in collaboration with Memorial Sloan Kettering Cancer Center (MSKCC), has uncovered a conformational switch - a change in shape in a carcinogen-damaged DNA site - in tumor suppressor genes altered by a known cancer-causing chemical found in cigarette smoke.

Nano-enabled drug discovery solutions will generate revenues of $1.3 billion in 2009

According to a new report by NanoMarkets, an industry consultancy based here, nano-enabled drug discovery solutions will generate revenues of $1.3 billion in 2009 and grow to $2.5 billion in 2012.

U.S. cancer researchers launch first American-Israeli cancer conference

Leading cancer researchers from Baltimore, Miami and New Jersey have organized the first Joint American-Israeli Conference on Cancer. The meeting, scheduled for March 16 through 18 in Jerusalem, seeks to foster collaboration among physicians and scientists in the two countries.

New study following 12,574 individuals over the course of three years of HAART

Although clinical progression to AIDS of patients infected with Human immunodeficiency virus (HIV) has declined since the introduction of Highly Active Antiretroviral Therapy (HAART), there is little data on the changes in incidence of AIDS-defining events during the first few years of therapy.

New compounds for the treatment of HIV/AIDS

Scientists from Tibotec Pharmaceuticals Ltd. presented data on several new compounds for the treatment of HIV/AIDS at the 12th Conference on Retroviruses and Opportunistic Infections (CROI), held February 22-25 in Boston, MA, USA.

New HIV screening method, nucleic acid amplification testing (NAAT)

Adding a new HIV screening method, called nucleic acid amplification testing (NAAT), to standard HIV testing, researchers were able to uncover six percent more cases of HIV infection in urban STD and drug treatment clinics and HIV testing sites in Atlanta than with standard HIV antibody tests alone.

Differences in how HIV virus infects males and females

A genetic analysis of viral RNA from 10 heterosexual couples, in which one partner has sexually transmitted HIV to the other, provides the first documentation of some differences in how the virus infects males and females.

Protein called CK2 plays a deadly role in colorectal carcinoma

A protein called CK2 plays a deadly role in colorectal carcinoma by blocking the ability of these tumors to activate a natural self-destruct mechanism that would clear this cancer from the body. This finding, by researchers at St. Jude Children's Research Hospital, is currently published in the online edition of Oncogene.

Scientists have replicated hepatitis C virus (HCV) in the laboratory

For the first time, scientists have replicated hepatitis C virus (HCV) in the laboratory. The ability to replicate HCV in cell culture will allow researchers to better study the life cycle and biology of this virus and to test potential antiviral compounds, which may lead to new therapies for the liver disease that results from infection with HCV.

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.
