P-bodies have a much broader role in controlling the activities of the cell than previously thought

Cells can reuse the chemical messengers that carry genetic information to the machinery that makes proteins. Sometimes cells shuttle the messengers to storage and later reactivate them to make proteins, according to new research.

Self-degradation response to antidepressant Zoloft observed in yeast cells

Princeton University researchers have observed a self-degradation response to the antidepressant Zoloft in yeast cells that could help provide new answers to lingering questions among scientists about how antidepressants work, as well as support the idea that depression is not solely linked to the neurotransmitter serotonin.

New technique to overcome genetic oddity of P. falciparum

The parasite that causes malaria is a genetic outlier, which has prevented scientists from discovering the functions of most of its genes. Researchers at National Jewish Health and Yale University School of Medicine have devised a technique to overcome the genetic oddity of Plasmodium falciparum, the major cause of human malaria.

Scientists discover how DNA mismatch repair proteins work

In eukaryotes - the group of organisms that include humans - a key to survival is the ability of certain proteins to quickly and accurately repair genetic errors that occur when DNA is replicated to make new cells.

Cisplatin anti-cancer drug binds pervasively to RNA

An anti-cancer drug used extensively in chemotherapy binds pervasively to RNA -- up to 20-fold more than it does to DNA, a surprise finding that suggests new targeting approaches might be useful, according to University of Oregon researchers.

Researchers use baker's yeast to gain insight into chromosome separation process

Researchers at the Stowers Institute for Medical Research used, ironically enough, the single-celled organism Saccharomyces cerevisiae -- commonly known as baker's yeast -- to gain new insight into the process by which chromosomes are physically segregated during cell division.

Budding yeast helps make useful predictions about the biology of individuals

It now only costs a few thousand Euros to sequence the genome of an individual human. However, for most of us, knowing our genome sequence would not be useful. Each human has more than 20 000 genes, and in each of us several thousand of these genes carry mutations.

Personal environment influences effects of genes and risk of disease

Personalized medicine centers on being able to predict the risk of disease or response to a drug based on a person's genetic makeup. But a study by scientists at Washington University School of Medicine in St. Louis suggests that, for most common diseases, genes alone only tell part of the story.

Study suggests H2O2 can act as anti-inflammatory compound

A major blow to the free radical theory of aging, which had lead the research in aging for more than 50 years and fuels a multimillionaire anti-aging industry has just been published by Portuguese scientists from the University of Minho. According to the theory, free radicals provoke oxidative damage and this is the cause of aging.

Yeast can be simple model to study molecular basis of Parkinson’s disease

Yeast could be a powerful ally in the discovery of new therapeutic drugs to treat Parkinson's disease says a scientist presenting his work at the Society for General Microbiology's autumn meeting in Nottingham today.

Researchers develop experimental approaches, analysis tools to understand phenotypic expression

The Human Genome Project, along with numerous parallel efforts to solve the DNA sequences of hundreds of animal, plant, fungal, and microbe genomes in the last few decades, has produced enormous amounts of genetic data with which researchers are struggling to keep pace.

Yeast produce a hormone that triggers fungal cells to become more infectious

In their ongoing studies of how yeast (fungi) can infect a host and cause disease, a research team at the Life Sciences and Bioengineering Center at Worcester Polytechnic Institute (WPI) has made an unexpected discovery. They found that yeast produce a hormone previously known to be made by plants, and that the presence of that hormone in sufficient quantity within the yeast's immediate environment triggers the fungal cells to become more infectious.

HZI researchers develop new method to produce insulin for treatment of diabetes

More than eight million diabetics live in Germany. Diabetes is not restricted to our prosperous society and the highest growth rates often occur in countries with aspiring economies such as in Asia. Worldwide, more than 285 million people suffer from this illness; with 50 million diabetics, India is the country with the most people affected by this disease.

Mapping of all fragile sites of yeast S.cerevisiae may lead to better understanding of cancer development

The research group of Dr. Fran-ois Robert, a researcher at the Institut de recherches cliniques de Montr-al (IRCM), in collaboration with the team of Dr. Daniel Durocher (Samuel Lunenfeld Research Institute and University of Toronto) accomplished a technical breakthrough: they mapped all the fragile sites of a living organism, the budding yeast Saccharomyces cerevisiae. The method used by the researchers can be applied to humans. This study has been published online today in the scientific journal Nature Structural and Molecular Biology.

New technology sheds light on intracellular transport

Using new technology developed in his University of Oregon lab, chemist Andrew H. Marcus and his doctoral student Eric N. Senning have captured what they describe as well-orchestrated, actin-driven, mitochondrial movement within a single cell.

WPI researchers develop new model system to study fungal infections

A team of researchers at the Worcester Polytechnic Institute (WPI) Life Sciences and Bioengineering Center at Gateway Park has developed a new model system to study fungal infections. The system can be a powerful tool for screening potential drug targets for conditions like thrush, athlete's foot and vaginal yeast infections, which affect millions of people each year but are difficult to treat with existing medications. Using the new model, the researchers also identified a gene that may be a promising target for a new anti-fungal drug.

Direct RNA sequencing performed using Helicos’ True Single Molecule Sequencing technology

Helicos BioSciences Corporation a life science company focused on innovative genetic analysis technologies, today announced the publication of a landmark study in which Helicos’ True Single Molecule Sequencing (tSMS)™ technology was used to directly sequence individual molecules of RNA. The paper appeared yesterday in the on-line edition of Nature and will appear in an upcoming 2009 print issue of Nature.

Same-sex mating found in most common human fungal pathogen Candida albicans

Brown University researchers have discovered that Candida albicans, a human fungal pathogen that causes thrush and other diseases, pursues same-sex mating in addition to conventional opposite-sex mating.

Discovery of possible mechanisms to protect against genetic alterations, diseases

Peering into the DNA of tiny yeast, researchers at the Moores Cancer Center at the University of California, San Diego and the San Diego Branch of the Ludwig Institute for Cancer Research have pinpointed a large number of genes that can prevent a type of genetic rearrangement that may lead to cancer and other diseases.
