From a Lowly Yeast, Researchers Divine a Clue to Human Disease

...p, led by Brow and Eric Steinmetz, compared normal yeast to a strain with a mutated form of Sen1 that does not see the stop signal. "The Sen1 mutant reads right through the stop sign and keeps going," Brow says. Without a properly functional Sen1, RNA polymerase II "reads through" the end of the gene and...

Chinese Red Yeast Rice Lowers Lipid Levels

NHGRI Aims To Sequence Primate Genomes

...d is a project to sequence up to 50 strains of the yeast Saccharomyces cerevisiae. The genome of Saccharomyces cerevisiae was first completed in 1996 and is a primary model for studying variations in genomes that can contribute to health and disease. The genomic data provided by this effort will allow rese...

Novel method conceived, to achieve genome-wide gene silencing.

.... Researchers conducted the study with a type of yeast called Saccharomyces cerevisiae, the scientists showed that a protein called SUMO holds on to the histones and acts to repress transcription of genes, and it does so at many different sites across the genome. While several other histone-related mecha...
