title: Senescence and apoptosis in yeast mother cell-specific aging and in higher cells: a short review.
abstract: It is our intention to give the reader a short overview of the relationship between apoptosis and senescence in yeast mother cell-specific aging. We are studying yeast as an aging model because we want to learn something of the basic biology of senescence and apoptosis even from a unicellular eukaryotic model system, using its unrivalled ease of genetic analysis. Consequently, we will discuss also some aspects of apoptosis in metazoa and the relevance of yeast apoptosis and aging research for cellular (Hayflick type) and organismic aging of multicellular higher organisms. In particular, we will discuss the occurrence and relevance of apoptotic phenotypes for the aging process. We want to ask the question whether apoptosis (or parts of the apoptotic process) are a possible cause of aging or vice versa and want to investigate the role of the cellular stress response system in both of these processes. Studying the current literature, it appears that little is known for sure in this field and our review will therefore be, for a large part, more like a memorandum or a program for future research.
