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

Oxygen stress: a regulator of apoptosis in yeast
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 …

[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 …
