Studies offer guide as protein interaction mapping comes of age

During the past 20 years, researchers have identified thousands of cell protein interactions, with the ultimate goal of inventorying all that occur within cells of various organisms - a comprehensive catalogue known as the interactome.

Discovery of new way for bacteria to transfer toxic genes to unrelated bacterial species

In a laboratory experiment, the scientists from NYU School of Medicine discovered that Staphylococcus aureus, a notorious bacterium that causes toxic shock syndrome and many other types of infections and is the scourge of hospitals nationwide due to its growing antibiotic resistance, could co-opt viral parasites as secret pipelines for transferring toxin genes to vastly different bacterial species.

Research initiative looks at helpful bacteria found on the skin

The study of ancient microbes may not seem consequential, but such pioneering research at the University of Oklahoma has implications for the state of modern human health.

Metadherin gene linked to metastasis of breast cancer

A team of researchers at Princeton University and The Cancer Institute of New Jersey has identified a long-sought gene that is fatefully switched on in 30 to 40 percent of all breast cancer patients, spreading the disease, resisting traditional chemotherapies and eventually leading to death.

Researchers show mechanisms that regulate DNA damage control and replication

Scientists at Burnham Institute for Medical Research (Burnham) have demonstrated important new roles for the protein kinase complex Cdc7/Dbf4 or Cdc7/Drf1 (Ddk) in monitoring damage control during DNA replication and reinitiating replication following DNA repair.

Discovery of new genetic markers for ulcerative colitis

An international team led by University of Pittsburgh School of Medicine researchers has identified genetic markers associated with risk for ulcerative colitis.

Culprit found in rare type of baldness

Scientists in Beijing say they have discovered a genetic cause for a certain type of premature baldness and they suggest their discovery offers hope in future that those who inherit this rare type of baldness will eventually be able to keep their hair.

New understanding of genetic signature associated with Alzheimer's disease

Scientists have new information about the complex genetic signature associated with Alzheimer's disease, the leading cause of cognitive decline and dementia in the elderly.

In lung cancer, silencing one crucial gene disrupts normal functioning of genome

While examining patterns of DNA modification in lung cancer, a team of international researchers has discovered what they say is a surprising new mechanism.

Few DNA repair gene variants associated with increased cancer risk

Variants of numerous DNA repair genes initially appeared to be statistically significantly associated with cancer risk in epidemiological studies.

Researchers identify common gene variant linked to high blood pressure

Researchers at the University of Maryland School of Medicine have identified a common gene variant that appears to influence people's risk of developing high blood pressure, according to the results of a study being published online Dec. 29, 2008 in the Proceedings of the National Academy of Sciences (PNAS).

Hexokinase-1 gene variation associated with widely used marker of blood glucose concentration

Scientists have found that genetic variation at the hexokinase-1 gene is linked to variation in the blood concentration of glycated hemoglobin, an index of long-term blood glucose concentration widely used in the follow-up of diabetes patients.

Researchers identify gene linked to inherited form of fatal lung disease

Researchers at UT Southwestern Medical Center have determined that a mutation in a gene known for its role in defending the lungs against invading pathogens is responsible for some inherited cases of a lethal lung disease affecting older adults. The same mutation may also be associated with lung cancer, the researchers said.

Cellular reprogramming, the 'Breakthrough of the Year' according to AAAS

In its annual list of the year's top ten scientific breakthroughs, the journal Science has given top honors to research that produced "made-to-order" cell lines by reprogramming cells from ill patients.

Genes involved in antibiotic resistance vary within a species

The recent emergence of multidrug resistance (MDR) in Acinetobacter baumannii, a bacteria that causes infections primarily among seriously ill patients in the intensive care unit who may have reduced immune systems, has raised concern in health care settings worldwide.

Single letter in the human genome points to risk for high cholesterol

Write out every letter in the human genome, one A, C, T or G per millimeter, and the text would be 1,800 miles long, roughly the distance from New York to Colorado.

Study of placenta unexpectedly leads to cancer gene

University of Rochester Medical Center scientists discovered a gene mutation that impairs the placenta and also is influential in cancer development, according to a study published online December 16, 2008, in the journal PLoS (Public Library of Science) Biology.

Tracking the molecular pathway to mixed-lineage leukemia

Infants and adults with the blood cancer mixed-lineage leukemia (MLL) typically have a poor prognosis, and most infants die before their first birthdays.

Researchers simplify creation induced pluripotent stem (iPS) cells

Bryce Carey, an MIT graduate student working in the lab of Whitehead Member Rudolf Jaenisch, spearheaded the effort by joining in tandem the four reprogramming genes through the use of bits of DNA that code for polymers known as 2A peptides. Working with others in the lab, he then manufactured a so-called polycistronic virus capable of expressing all four reprogramming genes once it is inserted into the genomes of mature mouse and human cells.
