Intramitotic Controls in the Fission Yeast
Abs t rac t . We have used a new cinemicroscopy technique in combination with antitubulin immunofluorescence microscopy to investigate the timing of mitotic events in cells of the fission yeast Schizosaccharomyces pombe having lengths at division between 7 and 60 #m. Wild-type fission yeast cells divide at a length of 14 #m. Separation of daughter nuclei (anaphase B) proceeds at a rate of 1.6 +...
متن کاملPma1, a P-type proton ATPase, is a determinant of chronological life span in fission yeast.
Chronological life span is defined by how long a cell can survive in a non-dividing state. In yeast, it is measured by viability after entry into stationary phase. To date, some factors affecting chronological life span have been identified; however, the molecular details of how these factors regulate chronological life span have not yet been elucidated clearly. Because life span is a complicat...
متن کاملMitochondrial Dysfunction Increases Oxidative Stress and Decreases Chronological Life Span in Fission Yeast
BACKGROUND Oxidative stress is a probable cause of aging and associated diseases. Reactive oxygen species (ROS) originate mainly from endogenous sources, namely the mitochondria. METHODOLOGY/PRINCIPAL FINDINGS We analyzed the effect of aerobic metabolism on oxidative damage in Schizosaccharomyces pombe by global mapping of those genes that are required for growth on both respiratory-proficien...
متن کاملYeast replicative life span--the mitochondrial connection.
Mitochondria have been associated with aging in many experimental systems through the damaging action of reactive oxygen species. There is more, however, to the connection between mitochondria and Saccharomyces cerevisiae longevity and aging. Induction of the retrograde response, a pathway signaling mitochondrial dysfunction, results in the extension of life span and postponement of the manifes...
متن کاملDdb1 controls genome stability and meiosis in fission yeast.
The human UV-damaged DNA-binding protein Ddb1 associates with cullin 4 ubiquitin ligases implicated in nucleotide excision repair (NER). These complexes also contain the signalosome (CSN), but NER-relevant ubiquitination targets have not yet been identified. We report that fission yeast Ddb1, Cullin 4 (Pcu4), and CSN subunits Csn1 and Csn2 are required for degradation of the ribonucleotide redu...
