Gene expression pattern could lead to improved treatment of pediatric septic shock

A consortium of researchers headed by Cincinnati Children's Hospital Medical Center has discovered a gene expression pattern that could lead to improved diagnosis and treatment of pediatric septic shock , still a serious public health problem despite today's potent antibiotics and pediatric intensive care units.

New algorithm matches any tumor cells to best possible anti-cancer treatments

Cancer patients don't have time to waste. Many go through several different treatments, however, to find one that is more effective against their particular type of tumor.

Effects of aging hematopoietic stem cells

There is little disagreement that the body's maintenance and repair systems deteriorate with age, even as there is plenty of disagreement as to why.

Simple method to comb genomes

Instead of immutable proprietary software, any species, genetic information resembles open source code that is constantly tweaked and optimized to meet the users specific needs.

Sequential and combination chemotherapy equally effective in treating advanced colorectal cancer

Many patients with incurable advanced colorectal cancer could be offered a more gentle treatment strategy starting with a single chemotherapy drug, as an alternative to current standard initial combination chemotherapy, without compromising their survival.

Discovery of one important function of junk DNA

Scientists have only recently begun to speculate that what's referred to as junk DNA , the 96 percent of the human genome that doesn't encode for proteins and previously seemed to have no useful purpose , is present in the genome for an important reason.

Scientists develop largest ever series of human breasts cancers grafted into mice

At the Institut Curie, Inserm researchers and physicians have established the largest ever panel of human breast cancer xenografts in animal models.

Discovery of enzyme critical in DNA replication

In this week's issue of Science, researchers from the National Institute of Environmental Health Sciences (NIEHS) and Umea University in Sweden report an important discovery about a critical new role that an enzyme called DNA polymerase epsilon plays in replicating DNA in higher organisms such as yeast and perhaps even humans.

RNA molecules can orchestrate gene activity across vast portions of the human genome

Large, seemingly useless pieces of RNA - a molecule originally considered only a lowly messenger for DNA - play an important role in letting cells know where they are in the body and what they are supposed to become, researchers at Stanford University School of Medicine have discovered.

Many of the areas of the human genome previously thought to be deserts are in fact teeming with life

Most known human genes in the genome map are still incompletely annotated, says Professor Alexandre Reymond, from the Centre for Integrative Genomics, University of Lausanne, Switzerland and the Department of Genetic Medicine, University of Geneva, Geneva, Switzerland.

True nature of heterochromatin revealed

Not so long ago, the difficult-to-sequence, highly repetitive, gene-poor DNA found in regions of chromosomes known as heterochromatin was called "junk." Like dark matter in the universe, the true nature of heterochromatin was unknown.

Researchers use 'genomic pathway' to predict Parkinson's

A new Mayo Clinic study provides strong evidence that the joint effects of common DNA variations in several genes that encode proteins within a well-defined biological pathway largely explain why some persons get Parkinson's disease while others don't, and even predict with great accuracy at what age people might develop their first symptoms.

Discovery of IKBKE gene linked to breast cancer

Using a novel three-part screening process, scientists at Dana-Farber Cancer Institute have identified a gene that is made inappropriately in about a third of all breast cancers.

The unexpected connection of two gene regulation mechanisms points to new ways for the fight against leukemia

When the activity of individual genes it is longer required, there are two main mechanisms responsible for the “switching off”, mainly DNA methylation and the Polycomb protein complex. Sometimes, these mechanisms lose their efficiency and some of the genes that should be "switched off" remain active.

Sensitivity to diverse range of chemotherapeutic drugs linked to common pathway

Using a functional genomic screen, scientists have defined elements that impact the responsiveness of cancer cells to drugs commonly used as anticancer therapeutics.

Physiological differences between men and women impact colorectal cancer progression

Physiological differences between men and women may contribute to differential tumor development and progression in colon cancer patients, a study led by researchers at the University of Southern California (USC) suggests.

New protocols to understand embryos, clones, stem cells

Cloning, X-chromosome inactivation, stem cells, and embryogenesis are hot areas of research at the moment, and protocols featured in this month's release of Cold Spring Harbor Protocols will aid these studies.

Virus widely used in gene therapy research yields important clues to genomic instability

Genomic instability, the rearrangement of chromosomes or an abnormal number of chromosomes, is a hallmark of many human cancers.

Complete sequencing of DNA pioneer James D. Watson

454 Life Sciences Corporation, in collaboration with scientists at the Human Genome Sequencing Center, Baylor College of Medicine, announced in Houston, Texas, the completion of a project to sequence the genome of James D. Watson, Ph.D., co-discoverer of the double-helix structure of DNA.
