Death ligand concentration and the membrane proximal signaling module regulate the type 1/ type 2 choice in apoptotic death signaling [PDF]
, 2015 Apoptotic death pathways are frequently activated by death ligand induction and subsequent activation of the membrane proximal signaling module. Death receptors cluster upon binding to death ligands, leading to formation of a membrane proximal death-inducing-signaling-complex (DISC). In this membrane proximal signalosome, initiator caspases (caspase 8)

Cleavage of DFNA5 by caspase-3 during apoptosis mediates progression to secondary necrotic/pyroptotic cell death. [PDF]
, 2017 Apoptosis is a genetically regulated cell suicide programme mediated by activation of the effector caspases 3, 6 and 7. If apoptotic cells are not scavenged, they progress to a lytic and inflammatory phase called secondary necrosis.

DECAY, a novel Drosophilacaspase related to mammalian caspase-3 and caspase-7. [PDF]
Journal of Biological Chemistry, 1999 Caspases are key effectors of programmed cell death in metazoans. In Drosophila, four caspases have been described so far. Here we describe the identification and characterization of the fifth Drosophila caspase, DECAY. DECAY shares a high degree of homology with the members of the mammalian caspase-3 subfamily, particularly caspase-3 and caspase-7 ...

Cleavage of the apoptosis inhibitor DIAP1 by the apical caspase DRONC in both normal and apoptotic drosophila cells [PDF]
, 2005 In Drosophila S2 cells, the apical caspase DRONC undergoes a low level of spontaneous autoprocessing. Unintended apoptosis is prevented by the inhibitor of apoptosis DIAP1, which targets the processed form of DRONC for degradation through its E3 ...

Cell Death & Differentiation, 1999 Caspases are the key effector molecules of the physiological death process known as apoptosis, although some are involved in activation of cytokines, rather than cell death. They exist in most of our cells as inactive precursors (zymogens) that kill the cell once activated. Caspases can be controlled in two ways.

Molecular Oncology, EarlyView.The complex mode of action of the topoisomerase II inhibitor etoposide in triggering apoptosis involves several mechanisms: overexpression of the mitochondrial protein VDAC1, leading to its oligomerization and formation of a large channel that mediates the release of pro‐apoptotic protein; and overexpression of the apoptosis regulators p53, Bax, and ...

Natural killer cells induce HIV-1 latency reversal after treatment with pan-caspase inhibitors
Frontiers in Immunology, 2022 The establishment of a latency reservoir is the major obstacle for a cure of HIV-1. The shock-and-kill strategy aims to reactivate HIV-1 replication in HIV -1 latently infected cells, exposing the HIV-1-infected cells to cytotoxic lymphocytes.

Effective description of bistability and irreversibility in apoptosis [PDF]
arXiv, 2021 Apoptosis is a mechanism of programmed cell death in which cells engage in a controlled demolition and prepare to be digested without damaging their environment. In normal conditions apoptosis is repressed, until it is irreversibly induced by an appropriate signal.

A non-apoptotic role for caspase-9 in muscle differentiation [PDF]
, 2008 Caspases, a family of cysteine proteases most often investigated for their roles in apoptosis, have also been demonstrated to have functions that are vital for the efficient execution of cell differentiation.
