Yeast models of cell death and survival mechanisms

European scientists investigated differences in the genomes of various distantly-related yeast and their effects on cell survival. Results may provide insight into cell death induced by free radicals.

Is the shape of a genome as important as its content?

If there is one thing that recent advances in genomics have revealed, it is that our genes are interrelated, "chattering" to each other across separate chromosomes and vast stretches of DNA. According to researchers at The ...

Cellular memory of stressful situations

Stress is unhealthy. The cells use therefore a variety of mechanisms to deal with stress and avert its immediate threat. However, certain stressful situations leave marks that go beyond the immediate response; some even seem ...

New tasks attributed to Aurora proteins in cell division

(PhysOrg.com) -- When a cell divides, the genetic information in the chromosomes must be passed on error-free to the daughter cells. Researchers at the Friedrich Miescher Laboratory in Tübingen are studying this process ...

Biologists identify proteins vital to chromosome segregation

New York University biologists have identified how a vital protein is loaded by others into the centromere, the part of the chromosome that plays a significant role in cell division. Their findings shed new light on genome ...

Imaging the genome: Cataloguing the fundamental processes of life

The team of researchers, led by Dr Rafael Carazo Salas from the Department of Genetics, combined high-resolution 3D confocal microscopy and computer-automated analysis of the images to survey the fission yeast genome with ...

New genetic switch allows cells to thrive in low oxygen

(PhysOrg.com) -- Johns Hopkins scientists have revealed a new way that cells respond to the challenge of low oxygen. A report on the discovery about how the fission yeast Schizosaccharomyces pombe regulates its genes in hypoxic ...
