Viral killer toxins induce caspase-mediated apoptosis in yeast
In yeast, apoptotic cell death can be triggered by various factors such as H2O2, cell aging, or acetic acid. Yeast caspase (Yca1p) and cellular reactive oxygen species (ROS) are key regulators of this process. Here, we show that moderate doses of three virally encoded killer toxins (K1, K28, and zygocin) induce an apoptotic yeast cell response, although all three toxins differ significantly in ...
متن کاملCalnexin Regulates Apoptosis Induced by Inositol Starvation in Fission Yeast
Inositol is a precursor of numerous phospholipids and signalling molecules essential for the cell. Schizosaccharomyces pombe is naturally auxotroph for inositol as its genome does not have a homologue of the INO1 gene encoding inositol-1-phosphate synthase, the enzyme responsible for inositol biosynthesis. In this work, we demonstrate that inositol starvation in S. pombe causes cell death with ...
متن کاملEndocytosis inhibition during H2O2-induced apoptosis in yeast.
Yeast revealed to be a versatile organism for studying endocytosis. Here, inhibition of endocytosis by H(2)O(2) and its correlation with apoptotic cell death were ascertained in Saccharomyces cerevisiae. We found that H(2)O(2) causes alterations in vacuolar morphology and a concentration-dependent inhibition of endocytosis. We also found that H(2)O(2)-induced endocytosis inhibition is a reversi...
متن کاملyApoptosis: yeast apoptosis database
In the past few years, programmed cell death (PCD) has become a popular research area due to its fundamental aspects and its links to human diseases. Yeast has been used as a model for studying PCD, since the discovery of morphological markers of apoptotic cell death in yeast in 1997. Increasing knowledge in identification of components and molecular pathways created a need for organization of ...
متن کاملYeast apoptosis debate continues
Yeast apoptosis debate continues east, as a unicellular organism, would seem to benefit most from self-preservation. But yeast altruism, in the form of apoptosis, is a new-found, if controversial, field of study. Many doubt the validity of experiments supporting programmed cell death in yeast and call for better controls. In this issue, the debate continues with two new articles that suggest th...
