[PDF][PDF] Bruchpilot, a protein with homology to ELKS/CAST, is required for structural integrity and function of synaptic active zones in Drosophila

…, M Schmidt, G Qin, C Wichmann, R Kittel, SJ Sigrist… - Neuron, 2006 - cell.com
Neurotransmitters are released at presynaptic active zones (AZs). In the fly Drosophila,
monoclonal antibody (MAB) nc82 specifically labels AZs. We employ nc82 to identify Bruchpilot …

Bruchpilot Promotes Active Zone Assembly, Ca2+ Channel Clustering, and Vesicle Release

…, KI Willig, SW Hell, E Buchner, M Heckmann, SJ Sigrist - Science, 2006 - science.org
The molecular organization of presynaptic active zones during calcium influx–triggered
neurotransmitter release is the focus of intense investigation. The Drosophila coiled-coil domain …

Cardioprotection and lifespan extension by the natural polyamine spermidine

…, T Pieber, R Pechlaner, J Willeit, SJ Sigrist… - Nature medicine, 2016 - nature.com
Aging is associated with an increased risk of cardiovascular disease and death. Here we
show that oral supplementation of the natural polyamine spermidine extends the lifespan of …

Chronological aging leads to apoptosis in yeast

…, S Wissing, S Büttner, M Fehr, S Sigrist… - The Journal of cell …, 2004 - rupress.org
During the past years, yeast has been successfully established as a model to study mechanisms
of apoptotic regulation. However, the beneficial effects of such a cell suicide program …

Oxygen stress: a regulator of apoptosis in yeast

F Madeo, E Fröhlich, M Ligr, M Grey, SJ Sigrist… - The Journal of cell …, 1999 - rupress.org
Oxygen radicals are important components of metazoan apoptosis. We have found that
apoptosis can be induced in the yeast Saccharomyces cerevisiae by depletion of glutathione or …

[PDF][PDF] A caspase-related protease regulates apoptosis in yeast

…, S Lächelt, M Herlan, M Fehr, K Lauber, SJ Sigrist… - Molecular cell, 2002 - cell.com
… Lä chelt,1 Mark Herlan,2 Markus Fehr,3 Kirsten Lauber,4 Stephan J. Sigrist,5 markers of
apoptosis such as DNA fragmentation, phosSebastian Wesselborg,4 and Kai-Uwe Frohlich6 …

[HTML][HTML] Drosophila fizzy-related down-regulates mitotic cyclins and is required for cell proliferation arrest and entry into endocycles

SJ Sigrist, CF Lehner - Cell, 1997 - cell.com
We demonstrate that fizzy-related (fzr), a conserved eukaryotic gene, negatively regulates
the levels of cyclins A, B, and B3. These mitotic cyclins that bind and activate cdk1(cdc2) are …

An AIF orthologue regulates apoptosis in yeast

…, KU Fröhlich, J Manns, C Candé, SJ Sigrist… - The Journal of cell …, 2004 - rupress.org
Apoptosis-inducing factor (AIF), a key regulator of cell death, is essential for normal mammalian
development and participates in pathological apoptosis. The proapoptotic nature of AIF …

Maturation of active zone assembly by Drosophila Bruchpilot

…, S Hallermann, RJ Kittel, S Eimer, SJ Sigrist - Journal of Cell …, 2009 - rupress.org
Synaptic vesicles fuse at active zone (AZ) membranes where Ca 2+ channels are clustered
and that are typically decorated by electron-dense projections. Recently, mutants of the …

[PDF][PDF] Endonuclease G regulates budding yeast life and death

…, D Ruli, H Knauer, C Ruckenstuhl, C Sigrist… - Molecular cell, 2007 - cell.com
Endonuclease G (EndoG) is located in mitochondria yet translocates into the nucleus of
apoptotic cells during human degenerative diseases. Nonetheless, a direct involvement of …
