Study links cell size with commitment to division

How does a cell know when to divide? We know that hundreds of genes contribute to a wave of activity linked to cell division, but to generate that wave new research shows that cells must first grow large enough to produce four key proteins in adequate amounts.

Researchers discover glutamine-dependent activation of cell growth and autophagy

The human body consists of about 35 trillion cells, so it could be said that overall body growth is the growth of individual cells.

Genetic diversity plays major role in evolution of drug resistance

Researchers have shown that genetic diversity plays a key role in enabling drug resistance to evolve. Scientists at the Wellcome Trust Sanger Institute and the Institute for Research on Cancer and Ageing of Nice in France, show that high genetic diversity can prime new mutations that cause drug resistance.

Understanding molecular mechanisms and metabolic pathways of yeast for drug discovery

My research uses budding yeast as a tool for synthetic biology, and also in chemical and functional genomic applications. We are interested in understanding molecular mechanisms and metabolic pathways of yeast for drug discovery.

Cancer cells may lose copies of ribosomal DNA to enable faster proliferation, study shows

Research from the Stowers Institute provides evidence suggesting that cancer cells might streamline their genomes in order to proliferate more easily.

Researchers reveal molecular mechanism of autophagy initiation

Researchers revealed that Atg13 links autophagy initiation factors to each other using a string-like conformation, thereby promoting the association of diverse elements of the autophagy initiation machinery, initiating autophagosome formation through the recruitment of Atg9 vesicles and phosphorylation of various Atg factors.

Continuous errors in damaged DNA repair may lead to tumor formation

A group of researchers at Osaka University found that if DNA damage response (DDR) does not work when DNA is damaged by radiation, proteins which should be removed remain instead, and a loss of genetic information can be incited, which, when repaired incorrectly, will lead to the tumor formation.

Two studies shed new light on nature of tandem DNA repeat arrays

A pair of studies by a team of scientists has shed new light on the nature of a particular type of DNA sequences—tandem DNA repeat arrays—that play important roles in transcription control, genome organization, and development.

FSU investigator solves cell division mystery

In the second part of his lab's recent one-two punch, Florida State University researcher Daniel Kaplan said he has solved a cell division mystery in a way that will intrigue the makers of cancer-fighting drugs.

Reducing incorrect gene expression can extend lifespan of cells

Working with yeast and worms, researchers found that incorrect gene expression is a hallmark of aged cells and that reducing such "noise" extends lifespan in these organisms. The team published their findings this month in Genes & Development.

Researchers discover how and where chromosome fragile sites occur in human DNA

Using a novel method they developed to map chromosome breaks in a model organism, the budding yeast, Wenyi Feng, Ph.D., of Upstate Medical University and her colleagues have discovered new information as to how and where chromosome fragile sites can occur in human DNA. These sites are frequently observed in cancer cells and are responsible for causing genomic rearrangements.

Scientists develop sophisticated assay to track cell growth at low nutrient concentrations

The budding yeast, Saccharomyces cerevisiae, is a prime organism for studying fundamental cellular processes, with the functions of many proteins important in the cell cycle and signaling networks found in human biology having first been discovered in yeast.

Penn State researchers find that protein changes can control gene functions

A Penn State-led research team has found that changes to proteins called histones, which are associated with DNA, can control whether or not a gene is allowed to function. The changes may be important in maintaining the genes' "expression potential" so that future cells behave as their parent cells did.

University of Leicester to launch new research centre to explore complex traits and disease

This week, the University of Leicester launches a new Centre for Genetic Architecture of Complex Traits to explore the building blocks of complex traits and disease.

Budding yeast an acceptable model system to study KP1019 anti-cancer drug

Researchers have found that the budding yeast (Saccharomyces cerevisiae) is an acceptable model system to study KP1019, an anti-cancer drug that uses ruthenium, a rare metal, a new study found. Researchers had previously been interested in studying KP1019 because it is believed to cause cancer cell death and is not known to have negative secondary side effects for healthy tissues.

Mod5 yeast prion contributes to cell survival under environmental stress

One of the greatest mysterious in cellular biology has been given a new twist thanks to findings reported in Science. Researchers at the RIKEN Brain Science Institute show that prions, proteins that transmit heritable information without DNA or RNA, can contribute to drug resistance and cellular adaptation. Their discovery of a yeast prion with these properties demonstrates the active role of the prion conversion in cellular fitness adaptation, providing new insights into the potentially broader function of prions in living organisms.

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.

Virginia Tech receives NIH grant to develop new systems biology approaches for cell study

The National Institutes of Health has awarded Virginia Tech researchers a $2.13 million grant to develop new systems biology approaches to study cells, one of the most basic units of life.

Tension-dependent stabilization helps chromosome separation machinery

Scientists have discovered an amazingly simple way that cells stabilize their machinery for forcing apart chromosomes. Their findings are reported Nov. 25 in Nature.

Study discovers multiple effects of SSRIs on cells

A new discovery about selective serotonin reuptake inhibitors (SSRIs) suggests that these drugs, which are used to treat mental health disorders like depression and anxiety, have multiple effects on our cells. In a research report published in the August 2010 issue of GENETICS, researchers used yeast cells to identify secondary drug targets or pathways affected by SSRIs. Such secondary pathways could help explain why different people taking the same drug may experience different effects, and could also lead to new types of drugs altogether.
