Tryptophan deficiency may underlie quinine side effects
Researchers have found that the anti-malarial drug quinine can block a cell's ability to take up the essential amino acid tryptophan, a discovery that may explain many of the adverse side-effects associated with quinine. view more (2009-06-29)
Cell survival depends on chromosome integrity
As part of a large National Institutes of Health-funded Technology Centers for Networks and Pathways project, Johns Hopkins researchers have discovered protein machinery important for cells to keep chromosomes intact. view more (2006-07-10)
University of Toronto scientists map entire yeast genome
University of Toronto scientists have devised a tool to help understand and predict the state of a cell by successfully mapping all 70,000 nucleosomes in yeast. Nucleosomes wrap DNA before it is transformed into proteins and are critical indicators and regulators of a cell's state. view more (2007-11-27)
DNA repair mechanisms relocate in response to stress
Like doctors making house calls, some DNA repair enzymes can relocate to the part of the cell that needs their help, a collaborative team of scientists at Emory University School of Medicine has found. view more (2009-03-27)
RNA interference found in budding yeasts
Some budding yeast species have the ability to silence genes using RNA interference (RNAi). Until now, most researchers thought that no budding yeasts possess the RNAi pathway because Saccharomyces cerevisiae, the protoypical model budding yeast does not. view more (2009-09-11)
The salt of life and genes
Mineral salts are essential for living organisms. To be precise, it is from these, living cells get their basic components, the ions. Common salt, for example, contains chloride and sodium ions which the cell uses to establish and maintain electrochemical balance with the environment. In order to achieve sodium equilibrium in animal cells, for... view more... (2003-04-16)
Baumann lab identifies elusive telomere RNA subunit in single cell model
The Stowers Institute's Baumann Lab has identified the long-sought telomerase RNA gene in a single-cell research model. Their findings have been posted to the Web site of the journal Nature Structural & Molecular Biology and will appear in a future print edition. view more (2007-12-28)
Man's best friend is his yeast
Man's best friend is not his dog - it's his yeast, according to Professor Steve Oliver from the University of Manchester, speaking at the BA Festival of Science in Glasgow today [3rd September 2001]. For more than 6,000 years mankind has used yeast to bake bread, brew beer and ferment wine - but today it's scientists who are using the... view more... (2001-08-30)
Prion discovery gives clue to control of mass gene expression
The discovery in common brewer's yeast of a new, infectious, misfolded protein -- or prion -- by University of Illinois at Chicago molecular biologists raises new questions about the roles played by these curious molecules, often associated with degenerative brain diseases like "mad cow" and its human counterpart, Creutzfeldt-Jakob. view more (2009-03-16)
Yeast model shows promise as Alzheimer's test
A century ago this month, German psychiatrist Alois Alzheimer formally described characteristics of the neurodegenerative disease which ultimately came to bear his name. view more (2006-11-20)
Evolution is driven by gene regulation
It is not just what's in your genes, it's how you turn them on that accounts for the difference between species - at least in yeast - according to a report by Yale researchers in this week's issue of Science. view more (2007-08-10)
Hotspots found for chromosome gene swapping
Crossovers and double-strand DNA breaks do not occur randomly on yeast chromosomes during meiosis, but are greatly influenced by the proximity of the chromosome's telomere, according to research in the laboratory of Whitehead Fellow Andreas Hochwagen. view more (2007-11-30)
Yeast missing sex genes undergo unexpected sexual reproduction
An emerging form of the pathogenic yeast Candida is able to complete a full sexual cycle in a test tube, even though it's missing the genes for reproduction. view more (2009-05-26)
Fitting in: Newly evolved genes adopt a variety of strategies to remain in the gene pool
When Mother Nature creates an identical copy of a gene in an organism's genome, the duplicated copy is usually deleted, inactivated, or otherwise rendered nonfunctional in order to prevent genetic redundancy and to preserve biological homeostasis. view more (2005-10-03)
Scientists encourage cells to make a meal of Huntington's disease
Scientists have developed a novel strategy for tackling neurodegenerative diseases such as Huntington's disease: encouraging an individual's own cells to "eat" the malformed proteins that lead to the disease. view more (2007-05-08)
Recurrent vaginal thrush should be treated more aggressively
Women who suffer recurrent vaginal thrush should use more prolonged courses of antifungal treatment initially to increase the chances of complete eradication of the yeast, finds a study in Sexually Transmitted Infections. Over 120 women attending the genitourinary clinic with signs and symptoms of vaginal thrush were included in the study. Swabs... view more... (2001-06-12)
Abertay scientist sets out to find undiscovered yeast
A University of Abertay Dundee scientist has braved scorching temperatures in harsh deserts to track down a new strain of "killer yeast" which could be used in agriculture and beer brewing. With a grant from NATO, Dr Graeme Walker recently flew out to Morocco to locate the Argan tree, a hardy plant which only grows in the arid climate of the... view more... (2002-05-03)
Salt of the Earth
A yeast gene responsible for salt tolerance has successfully been used to grow tobacco in a salty environment lethal to most plants. Dr Janey Henderson and Professor Phil Harris from Coventry University inserted the halotolerance gene HAL1 from yeast into a tobacco plant. HAL1 has previously been shown to confer salt tolerance in transgenic tomato... view more... (2001-04-04)
Producing bio-ethanol from agricultural waste a step closer
Research conducted by Delft University of Technology has brought the efficient production of the environmentally-friendly fuel bio-ethanol a great deal closer to fruition. view more (2006-06-08)
Scientists discover gene mutation responsible for hereditary neuroendocrine tumor
University of Utah researchers and their colleagues have identified the gene that is mutated in a hereditary form of a rare neuroendocrine tumor called paraganglioma (PGL). view more (2009-07-24)
