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.

Osteopontin-c is a good biomarker of breast cancer.

Researchers have identified a molecule that may be more accurate than existing biological signposts used to predict which breast cancers will develop into advanced forms of the disease.

Hairpin peptide mimetics show promise as new drugs to fight HIV

When a host cell is infected with HIV, the virus brings its own genetic material into the host cell. This cell then replicates, reads the viral RNA, and uses it as a blueprint to produce more viral proteins.

Regulation of TATA-less promoters

In their upcoming G&D paper, Dr. Robert Tjian (UC Berkeley) and colleagues reveal how histone gene expression is differentially regulated during Drosophila development.

Cutting-edge method that captures cell growth and activity

This month's issue of Cold Spring Harbor Protocols features a cutting-edge method that provides a snapshot of growth and activity patterns in mixed populations of cells. The protocol is freely accessible online.

Not just humans benefit from animal biotechnology

Laboratory animals are the source of major discoveries and breakthroughs in biology, not just in tackling disease but also unravelling fundamental molecular processes.

Simple blood test may accurately detect thoracic aneurysm disease

Yale scientists have discovered a way to use a simple blood test that may accurately detect thoracic aneurysm disease (TAA), which gives little warning and is almost always fatal if untreated.

Gold-like drugs to treat arthritis

Scientists at Duke University Medical Center may have solved the mystery surrounding the healing properties of gold - a discovery they say may renew interest in gold salts as a treatment for rheumatoid arthritis and other inflammatory diseases.

New mechanism discovered that mammalian cells employ to fight infections of the Hepatitis C virus

A team of researchers led by biologists at the University of California, San Diego has discovered a completely new mechanism that mammalian cells employ to fight infections of the Hepatitis C virus, which affects approximately 2.7 million Americans and 170 million people worldwide.

Newly solved structure reveals how cells resist oxygen damage

The sun's rays give life, but also take it away. Singlet oxygen, a byproduct of the photosynthetic process by which certain cells convert sunlight into energy, is a highly toxic and reactive substance that tears cells apart.

New insight into Herceptin resistance in breast cancer

A new study provides important insight into the mechanisms involved in resistance to treatment of breast cancer patients with trastuzumab (Herceptin). The research, published by Cell Press in the October issue of the journal Cancer Cell , identifies markers that may help to identify patients who are unlikely to respond to trastuzumab treatment and provides a potential strategy for treating these patients.

Enhanced DNA-repair mechanism can cause breast cancer

Although defects in the "breast cancer gene," BRCA1, have been known for years to increase the risk for breast cancer, exactly how it can lead to tumor growth has remained a mystery.

New gene findings show that controls of lifespan and cancer have deep, common roots

A person is 100 times more likely to get cancer at age 65 than at age 35. But new research reported in the journal "Nature Genetics" identifies naturally occurring processes that allow many genes to both slow aging and protect against cancer in the much-studied C. elegans roundworm.

RNA-binding protein key to understanding myotonic dystrophy type 1

Increased levels of a protein called CUGBP1 play an important role in the adult-onset form of muscular dystrophy called myotonic dystrophy type 1, said Baylor College of Medicine researchers in a report that appears in the journal Molecular Cell.

Reservoir of Marburg virus identified in a species of fruit bat

The Marburg virus, like its fearsome cousin Ebola, belongs to the Filoviridae family. It carries the name of the German town where it was first detected in 1967, after a mysterious epidemic had hit employees of the Behring laboratory.
