Researchers identify genetic machinery responsible for synthesizing thiostrepton

Researchers at the Georgia Institute of Technology have identified the genetic machinery responsible for synthesizing thiostrepton, a powerful antibiotic produced by certain bacteria.

Scientists make a new protein from scratch

No doubt proteins are complex. Most are "large" and full of interdependent branches, pockets and bends in their final folded structure.

Discovery of genetic link to blood cancers

The study, published in the journal Nature Genetics, has shown that susceptibility to a series of blood cancers, known as myeloproliferative disorders (MPDs), is linked to a particular area of the patient's DNA, which is prone to developing mutations.

Epigenetic mark guides stem cells toward their destiny

Not all stem cells are completely blank slates. Some, known as adult stem cells, have already partially embraced their fates, and are capable of becoming only cells of a particular type of tissue.

Epigenetic mark guides stem cells toward their destiny

Not all stem cells are completely blank slates. Some, known as adult stem cells, have already partially embraced their fates and are capable of becoming only cells of a particular type of tissue. So how do these tissue-specific stem cells restrict their fate?

New tumor markers determine therapy intensity

Characteristic changes in the DNA of medulloblastoma, the most frequent malignant brain tumor in childhood, indicate precisely how aggressively the tumor will continue to spread and what the chances of disease relapse are.

Researchers show how proteins find the right DNA sequences

Researchers at Uppsala University and Harvard University have collaboratively developed a new theoretical model to explain how proteins can rapidly find specific DNA sequences, even though there are many obstacles in the way on the chromosomes.

Study reinforces the importance of healthy living for women

Women who maintain a healthy weight and who have lower perceived stress may be less likely to have chromosome changes associated with aging than obese and stressed women, according to a pilot study that was part of the Sister Study.

Potential pathway for drug intervention

A newly identified molecular pathway that directs stem cells to produce glial cells yields insights into the neurobiology of Down's syndrome and a number of central nervous system disorders characterized by too many glial cells, according to a recent study by researchers at the Salk Institute for Biological Studies.

Researchers look at genetic dynamics of inbreeding depression

Researchers have taken a first look at the broad genetic changes that accompany reproductive declines in inbred populations.

Smokers' chronic obstructive pulmonary disease risk is genetic

It's well known that puffing on cigarettes can eventually leave you out of puff.

Measuring the strength needed to move chromosomes

It's about as long as the width of a human hair and only half that length across. So it's tiny - measured in millionths of a meter - and extremely tricky to manipulate. But the meiotic spindle plays so irresistibly important a role in separating our chromosomes during cell division that scientists are compelled to try to study it.

Molecule tracking reveals mechanism of chromosome separation in dividing cells

University of Washington (UW) researchers are helping to write the operating manual for the nano-scale machine that separates chromosomes before cell division.

Genes more important in cleft lip and palate than previously thought

Comparing 500,000 snippets of human DNA put scientists from the University of Bonn on the right track.

Blood test predicts chance of frontal lobe dementia

Frontal lobe dementia (Frontotemporal Dementia, FTD) strikes people at an earlier age. After Alzheimer's disease, FTD is the form of dementia that occurs most frequently in patients younger than 65.

New DNA test is basis for groundbreaking IVF refund plan

The Sher Institutes of Reproductive Medicine (SIRM) announced today the introduction of the world's first CGH-Risk Sharing Plan that guarantees qualified IVF patients a baby or offers a full refund of the clinic's medical fees.

Discovery of new gene associated with Lou Gehrig's disease

A collaborative research effort spanning nearly a decade between researchers at Massachusetts General Hospital (MGH), MIT, the Broad Institute, King's College London (KCL) and other institutions has identified a novel gene for inherited amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease).

Molecular test for cancer relapse in UK children

A molecular marker used in America to predict whether children with a form of kidney cancer, called Wilms' tumour, are more likely to relapse than other children, could be useful for UK patients.

Researchers isolate gene mutations in patients with inherited amyotrophic lateral sclerosis

Researchers at the University of Massachusetts Medical School (UMMS) have discovered a new gene whose mutations cause familial amyotrophic lateral sclerosis (ALS), a fatal neurological disorder.
