Bioinformatics is the application of information techniques for the storage, retrieval, and analysis of large quantities of biological data.

Mouse Brain Gene Expression Map at St. Jude - powerful new tool for studying brain development

Scientists at St. Jude Children's Research Hospital have given investigators around the world free access to a powerful tool for studying brain development.

Crucial breakthrough in pectin biosynthesis

Most people know pectin as a common household gelling agent in making jams and jellies, but its uses are vast. It has anticancer properties, for instance, and may have a role in important biological functions including plant growth and development and defense against disease.

Researchers use computer simulations to mimic DNA mess inside the nucleus

Almost three metres of tightly-coiled DNA strands fit into a cell's nucleus. As DNA replicates, the strands unwind and unfold and then re-package into chromosomes, the genetic blueprints of life - but what happens if this process becomes entangled?

Artificial intelligence addresses the problem of confusing drug names

Was that Xanex or Xanax? Or maybe Zantac? If you're a health care professional you'd better know the difference--mistakes can be fatal.

Analysis of protein interactions dispels old notions of what's important about them

Discoveries made during the first large-scale analysis of interactions between proteins in our cells hold promise for identifying new genes involved in genetic diseases, according to researchers at Johns Hopkins and the Institute of Bioinformatics (IOB) in Bangalore.

Cell growth and cell division genes identified

A recent study shows that hundreds of genes contribute to cell growth and cell division. For the first time these genes, many of which are potential contributors to cancer, have been mapped in a single systematic study.

Researchers show how estrogen turns genes on and off during cancer progression

Ohio - A new study suggests that the hormone estrogen works in partnership with other proteins to activate or suppress gene activity in breast cancer cells.

Counting cells that ensure gene balance

Two are one too many - this is the motto used by cells of a female organism: These contain two X chromosomes, one of which always becomes inactivated.

First large-scale bird flu genome study

Investigators at St. Jude Children's Research Hospital have completed the first large-scale study of bird flu virus genomes, thereby doubling the amount of genetic information available on the genes and proteins of these viruses.

First genome-wide screen for protein complexes is completed

Researchers in Germany have finished the first complete analysis of the "molecular machines" in one of biology's most important model organisms: S. cerevisiae (baker's yeast). The study from the biotechnology company Cellzome, in collaboration with the European Molecular Biology Laboratory (EMBL), appears in this week's online edition of Nature.

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 type of sulfite reductase

Biswarup Mukhopadhyay and Eric Johnson from the Virginia Bioinformatics Institute at Virginia Tech have discovered a novel enzyme that represents an ancient detoxification system and provides a clue to the development of early metabolism on earth.

Fundamental insight about protein evolution

While searching for new targets for malaria drugs and vaccines, a team including a Howard Hughes Medical Institute (HHMI) medical student fellow reached a fundamental insight about evolution: different species make use of similar sets of proteins in different ways.

New method to find deadly malaria parasite

Researchers at UCSD have discovered that the single-cell parasite responsible for an estimated 1 million deaths per year worldwide from malaria has protein "wiring" that differs markedly from the cellular circuitry of other higher organisms

Gene fusion appears to cause prostate cancer

Scientists at the University of Michigan Medical School, in collaboration with researchers at Harvard's Brigham and Women's Hospital, have discovered a recurring pattern of scrambled chromosomes and abnormal gene activity that occurs only in prostate cancer.

Personalized medicine to improve the outcome for breast cancer patients

As cancer remains a leading cause of death in the United States, early detection and treatment are critical keys to improving the survival rate. Yet, an individual's response to treatment varies considerably, even among cancers of the same histological type.

Influenza evolution in action

On the eve of the 2005-06 flu season, scientists at The Institute for Genomic Research (TIGR) have captured influenza evolution in action. In a study published in this week's journal Nature, the researchers report the first large-scale project to sequence the influenza virus.

First identification of the genetic basis of disease in a patient with a complex I assembly defect

Mitochondrial complex I deficiency is one of the most common defects in patients with mitochondrial disease. The deficiency results from a failure to assemble the enzyme properly, but the nature of the molecular chaperones that are necessary for this process in mammals have remained obscure.

Computer program helps explain how the same proteins can play different roles in a wide range of cellular processes

University of California, San Diego biochemists have developed a computer program that helps explain a long-standing mystery: how the same proteins can play different roles in a wide range of cellular processes, including those leading to immune responses and cancer.

Mutations in receptor tyrosine kinases provide potential for highly-targeted cancer therapies

Scientists from J. Craig Venter Institute, Ludwig Institute for Cancer Research, and The Johns Hopkins University School of Medicine identified three novel mutations in two receptor tyrosine kinases in glioblastoma tumors using high throughput sequencing.
