A cellular genome-wide association study reveals human variation in microtubule stability and a role in inflammatory cell death.
(Mol Biol Cell, 2014-01)Pyroptosis is proinflammatory cell death that occurs in response to certain microbes. Activation of the protease caspase-1 by molecular platforms called inflammasomes is required for pyroptosis. We performed a cellular ... -
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 ... -
A network of substrates of the E3 ubiquitin ligases MDM2 and HUWE1 control apoptosis independently of p53.
(Sci Signal, 2013-05-07)In the intrinsic pathway of apoptosis, cell-damaging signals promote the release of cytochrome c from mitochondria, triggering activation of the Apaf-1 and caspase-9 apoptosome. The ubiquitin E3 ligase MDM2 decreases the ... -
A novel, non-apoptotic role for Scythe/BAT3: a functional switch between the pro- and anti-proliferative roles of p21 during the cell cycle.
(2012)Scythe/BAT3 is a member of the BAG protein family whose role in apoptosis, a form of programmed cell death, has been extensively studied. However, since the developmental defects observed in Bat3‐null mouse embryos cannot ... -
A selective inhibitor of eIF2alpha dephosphorylation protects cells from ER stress.
(Science (New York, N.Y.), 2005-02)Most protein phosphatases have little intrinsic substrate specificity, making selective pharmacological inhibition of specific dephosphorylation reactions a challenging problem. In a screen for small molecules that protect ... -
A SMAP in the face for cancer.
(The Journal of clinical investigation, 2017-06)Observed deficits in protein phosphatase 2A (PP2A) function in a variety of human cancers have stimulated drug discovery efforts aimed at restoring PP2A function to inhibit tumor growth. Work published by Sangodkar et al. ... -
AAV Gene Therapy for MPS1-associated Corneal Blindness.
(Scientific reports, 2016-02-22)Although cord blood transplantation has significantly extended the lifespan of mucopolysaccharidosis type 1 (MPS1) patients, over 95% manifest cornea clouding with about 50% progressing to blindness. As corneal transplants ... -
ACLY and ACC1 Regulate Hypoxia-Induced Apoptosis by Modulating ETV4 via α-ketoglutarate.
(PLoS Genet, 2015-10)In order to propagate a solid tumor, cancer cells must adapt to and survive under various tumor microenvironment (TME) stresses, such as hypoxia or lactic acidosis. To systematically identify genes that modulate cancer cell ... -
Afatinib induces apoptosis in NSCLC without EGFR mutation through Elk-1-mediated suppression of CIP2A.
(Oncotarget, 2015-02)Afatinib has anti-tumor effect in non-small cell lung carcinoma (NSCLC) with epidermal growth factor receptor (EGFR) mutation. We found afatinib can also induce apoptosis in NSCLC cells without EGFR mutation through CIP2A ... -
Akt, Glucose Metabolism, and the Bcl-2 Family
(2010)Normal cells require input from extrinsic growth factors to control proliferation and survival. Recent studies have demonstrated that these same extrinsic signals also regulate cellular metabolism to ensure that metabolism ... -
Alterations in β-Cell Sphingolipid Profile Associated with ER Stress and iPLA2β: Another Contributor to β-Cell Apoptosis in Type 1 Diabetes.
(Molecules (Basel, Switzerland), 2021-10)Type 1 diabetes (T1D) development, in part, is due to ER stress-induced β-cell apoptosis. Activation of the Ca2+-independent phospholipase A2 beta (iPLA2β) leads to the generation of pro-inflammatory eicosanoids, which contribute ... -
Analysis of Epstein-Barr virus-regulated host gene expression changes through primary B-cell outgrowth reveals delayed kinetics of latent membrane protein 1-mediated NF-κB activation.
(Journal of virology, 2012-10)Epstein-Barr virus (EBV) is an oncogenic human herpesvirus that dramatically reorganizes host gene expression to immortalize primary B cells. In this study, we analyzed EBV-regulated host gene expression changes following ... -
Antagonizing the irreversible thrombomodulin-initiated proteolytic signaling alleviates age-related liver fibrosis via senescent cell killing.
(Cell research, 2023-07)Cellular senescence is a stress-induced, stable cell cycle arrest phenotype which generates a pro-inflammatory microenvironment, leading to chronic inflammation and age-associated diseases. Determining the fundamental molecular ... -
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 ... -
Candidate genes on murine chromosome 8 are associated with susceptibility to Staphylococcus aureus infection in mice and are involved with Staphylococcus aureus septicemia in humans.
(PloS one, 2017-01)We previously showed that chromosome 8 of A/J mice was associated with susceptibility to S. aureus infection. However, the specific genes responsible for this susceptibility are unknown. Chromosome substitution strain 8 ... -
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 ... -
Circulating Autoantibodies in Age-Related Macular Degeneration Recognize Human Macular Tissue Antigens Implicated in Autophagy, Immunomodulation, and Protection from Oxidative Stress and Apoptosis.
(PLoS One, 2015)BACKGROUND: We investigated sera from elderly subjects with and without age-related macular degeneration (AMD) for presence of autoantibodies (AAbs) against human macular antigens and characterized their identity. METHODS: ... -
Copper signaling axis as a target for prostate cancer therapeutics.
(Cancer Res, 2014-10-15)Previously published reports indicate that serum copper levels are elevated in patients with prostate cancer and that increased copper uptake can be used as a means to image prostate tumors. It is unclear, however, to what ... -
Cryopreserved Mesenchymal Stromal Cells Are Susceptible to T-Cell Mediated Apoptosis Which Is Partly Rescued by IFNγ Licensing.
