ALERT: This system is being upgraded on Tuesday December 12. It will not be available
for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

A decade of caspases.
(Oncogene, 2003-11)Caspases are a family of cysteine proteases that play important roles in regulating apoptosis. A decade of research has generated a wealth of information on the signal transduction pathways mediated by caspases, the distinct ... -
A genome-wide RNAi screen reveals multiple regulators of caspase activation.
(The Journal of cell biology, 2007-11-12)Apoptosis is an evolutionally conserved cellular suicide mechanism that can be activated in response to a variety of stressful stimuli. Increasing evidence suggests that apoptotic regulation relies on specialized cell death ... -
Apoptosis in Drosophila: neither fish nor fowl (nor man, nor worm).
(J Cell Sci, 2005-05-01)Studies in a wide variety of organisms have produced a general model for the induction of apoptosis in which multiple signaling pathways lead ultimately to activation of the caspase family of proteases. Once activated, these ... -
Caspases: an ancient cellular sword of Damocles.
(Cell death and differentiation, 2004-01)Caspases are a family of cysteine proteases homologous to the Caenorhabditis elegans programmed cell death gene product CED-3. Caspases and their distant relatives, meta- and paracaspases, have been found in phylogenetically ... -
Cryopreserved Mesenchymal Stromal Cells Are Susceptible to T-Cell Mediated Apoptosis Which Is Partly Rescued by IFNγ Licensing.
(Stem cells (Dayton, Ohio), 2016-09)We have previously demonstrated that cryopreservation and thawing lead to altered Mesenchymal stromal cells (MSC) functionalities. Here, we further analyzed MSC's fitness post freeze-thaw. We have observed that thawed MSC ... -
Differential Apaf-1 levels allow cytochrome c to induce apoptosis in brain tumors but not in normal neural tissues.
(Proc Natl Acad Sci U S A, 2007-12-26)Brain tumors are typically resistant to conventional chemotherapeutics, most of which initiate apoptosis upstream of mitochondrial cytochrome c release. In this study, we demonstrate that directly activating apoptosis downstream ... -
Engineering a BCR-ABL-activated caspase for the selective elimination of leukemic cells.
(Proc Natl Acad Sci U S A, 2013-02-05)Increased understanding of the precise molecular mechanisms involved in cell survival and cell death signaling pathways offers the promise of harnessing these molecules to eliminate cancer cells without damaging normal cells. ... -
Ligation of cell surface GRP78 with antibody directed against the COOH-terminal domain of GRP78 suppresses Ras/MAPK and PI 3-kinase/AKT signaling while promoting caspase activation in human prostate cancer cells.
(Cancer Biol Ther, 2010-01)We have previously shown that treatment of prostate cancer and melanoma cells expressing GRP78 on their cell surface with antibody directed against the COOH-terminal domain of GRP78 upregulates and activates p53 causing ... -
Site-specific phosphorylation and caspase cleavage of GFAP are new markers of Alexander disease severity.
(eLife, 2019-11-04)Alexander disease (AxD) is a fatal neurodegenerative disorder caused by mutations in glial fibrillary acidic protein (GFAP), which supports the structural integrity of astrocytes. Over 70 GFAP missense mutations cause AxD, ... -
Unc93b Induces Apoptotic Cell Death and Is Cleaved by Host and Enteroviral Proteases.
(PloS one, 2015-01)Unc93b is an endoplasmic reticulum (ER)-resident transmembrane protein that serves to bind and traffic toll-like receptors (TLRs) from the ER to their appropriate subcellular locations for ligand sensing. Because of its ...
