Johansson et al., Cell Death Differ 2003
:
Cathepsin D mediates cytochrome c release and
caspase activation in human fibroblast apoptosis induced by staurosporine
Emert-Sedlak et al., Mol Cancer Ther 2005
:
Involvement of
cathepsin D in chemotherapy induced cytochrome c release,
caspase activation , and cell death ... Moreover,
cathepsin D down-regulation significantly
delayed cytochrome c release and
caspase-3 activation in response to chemotherapy treatment
Stroikin et al., Biogerontology 2007
:
Increase of lysosomal pH was significantly less prominent in lipofuscin loaded cells than in controls and was accompanied neither by leakage of
cathepsin D nor by
caspase-3 activation even 96 h after the initiation of starvation
Albee et al., J Leukoc Biol 2007
(Escherichia coli Infections) :
Collectively, these data suggest that
cathepsin D activation of
caspase 3/7 may be required for inducing one of the death pathways elicited by E. coli
Lee et al., Neurochem Int 2007
(Parkinson Disease) :
Cathepsin D (CD) and
caspase-3 activity also
increased following exposure to 6-OHDA
Conus et al., J Exp Med 2008
(Inflammation...) :
Caspase-8 is
activated by
cathepsin D initiating neutrophil apoptosis during the resolution of inflammation ... We describe a new proapoptotic pathway in which
cathepsin D directly
activates caspase-8 ... Pharmacological or genetic inhibition of
cathepsin D resulted in delayed
caspase activation and reduced neutrophil apoptosis
PadrĂ³n-Barthe et al., Biochim Biophys Acta 2008
:
Cathepsin D enhances
caspase activity in the cell by cleaving procaspase-8 and LEI overexpression slows down this cleavage, protecting cells from apoptosis
Conus et al., J Biol Chem 2012
:
A direct and fast
activation of
caspase-8 by
cathepsin D was shown to be crucial in the initial steps of neutrophil apoptosis ... At acidic pH,
cathepsin D specifically cleaved caspase-8 but not the initiator caspase-9 or -10 and significantly
increased caspase-8 activity in dimerizing conditions
