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.

New target for muscular dystrophy drug therapy

Researchers at the University of Pennsylvania School of Medicine report how the gene for utrophin, which codes for a protein very similar to dystrophin, the defective protein in Duchenne muscular dystrophy (DMD), puts the brakes on its own expression in muscle cells, thereby suggesting a new target for treatment.

Helpful hints for healthy diets

With the number of Americans overweight and obese at an all-time high, the diet choices of young people are of concern, especially as they prepare to leave home for the first time in the fall and fend for themselves at college.

Scientists discover human genes hover between "on"and "off" in any given cell

Biologists have long thought that a simple on/off switch controls most genes in human cells.

Bak protein's deadly double whammy

When a cell is seriously stressed, say by a heart attack, stroke or cancer, a protein called Bak just may set it up for suicide, researchers have found.

Rochester now offers gene test to detect Batten disease

Rochester has become one of only a handful of communities around the world to offer a genetic test to detect Batten disease, a deadly inherited disorder.

Wilmot Cancer Center studies new chemo pill for lymphoma

Doctors at the University of Rochester's James P. Wilmot Cancer Center are first in the world to study a new, targeted agent that zeroes-in on B-cell lymphomas. The new twice-a-day pill offers patients with recurrent disease another choice as their options grow thin.

St. Jude study holds promise for improving neuroblastoma treatment

A treatment for neuroblastoma that lands a one-two punch works best when the second punch is timed to take maximum advantage of the first one, according to results of studies at St. Jude Children's Research Hospital.

Some smokers have genetic predisposition to develop chronic obstructive pulmonary disease

Some people have a genetic variation that makes them more susceptible to chronic obstructive pulmonary disease (COPD) if they smoke tobacco, according to new research from Wake Forest University School of Medicine and colleagues.

New approach to predict protein function

In a paper published online this month in the journal Nature Chemical Biology, researchers report that they have developed a way to determine the function of some of the hundreds of thousands of proteins for which amino acid sequence data are available, but whose structure and function remain unknown.

Startling discovery on the development of human embryonic stem cells

In this week's Nature, researchers of the McMaster Cancer and Stem Cell Research Institute show that human embryonic stem (ES) cells can actually produce distinctive niche cells, which then release stem-cell nourishing proteins to help keep their parents ticking over.

Chemically-modified mitochondrial toxin could lead to a new molecularly-targeted chemo drug

A chemically-modified version of a mitochondrial toxin long used to control species of invasive fish in lakes has been found to selectively inhibit two "survival proteins" in cancer cells.

New evidence of very recent human adaptation

A Cornell study of genome sequences in African-Americans, European-Americans and Chinese suggests that natural selection has caused as much as 10 percent of the human genome to change in some populations in the last 15,000 to 100,000 years, when people began migrating from Africa.

New advance in search for effective treatment for human liver cancer

Researchers from the University of Pittsburgh School of Medicine report a significant new advance in the search for an effective treatment for human liver cancer in the July issue of Molecular Cancer Therapeutics.

New model of early biological evolution

In a study publishing in PLoS Computational Biology, Shakhnovich et al present a new model of early biological evolution , the first that directly relates the fitness of a population of evolving model organisms to the properties of their proteins.

New use for a cell toxin found to inhibit survival proteins in cancer cells

A chemically-modified version of a mitochondrial toxin long used to control species of invasive fish in lakes has been found to selectively inhibit two "survival proteins" in cancer cells.

Cancer-causing enzyme could be stopped

Scientists from the MRC's Laboratory of Molecular Biology (LMB) and the Albert Einstein College of Medicine have discovered a way to stop an enzyme responsible for many cancers.

Baxter presents findings from the ADAPT study

Baxter Healthcare Corporation has announced the presentation of findings from the ADAPT (Analysis of Data from ADVATE Prospective Trials) study program database showing a statistically significant relationship between the duration of time spent with factor VIII blood levels below one international unit per deciliter (1 IU/dL, one percent of normal factor VIII level) and an increase in the annual bleed rate in people with hemophilia A.

Master switch for the production of brown fat discovered

Researchers at Dana-Farber Cancer Institute have identified a long-sought "master switch" in mice for the production of brown fat, a type of adipose tissue that generates heat and counters obesity caused by overeating.
