Copper Depletion Nanoparticles Potentiate Cancer Immunotherapy by Avoiding Innate and Adaptive Immune Resistance

Advanced Science, EarlyView.
A mitochondria‐targeted copper depletion nanoplatform (CYN‐CDA@Alb) was developed to selectively disrupt tumor mitochondria copper, which then reprogrammed the tumor immune microenvironment by depressing PD‐L1 and CD47 expression simultaneously. By doing this, CYN‐CDA@Alb reversed radiotherapy‐induced immune tolerance, showing the potential usage of ...

Deficiency in caspase-9 or caspase-3 induces compensatory caspase activation

Nature Medicine, 2000
Dysregulation of apoptosis contributes to the pathogenesis of many human diseases. As effectors of the apoptotic machinery, caspases are considered potential therapeutic targets. Using an established in vivo model of Fas-mediated apoptosis, we demonstrate here that elimination of certain caspases was compensated in vivo by the activation of other ...

Caspase-9 regulation: An update

Apoptosis, 2004
The complex sequence of events leading to apoptotic cell death is governed by an elaborate regulatory scheme involving the actions of both initiator and executioner proteases. Among the most intensively studied of the initiator caspases is caspase-9, an essential throughput element in the so-called intrinsic or mitochondrially gated pathway of ...

Akt Phosphorylation Site Found in Human Caspase-9 Is Absent in Mouse Caspase-9

Biochemical and Biophysical Research Communications, 1999
Caspase-9 is one caspase upstream of caspase-3 and its activation is stimulated by Apaf-1/cytochrome c and inhibited by Akt signals. BAD phosphorylation by Akt is an essential step for growth factor-mediated inhibition of caspase activation. Recently, it was shown that human caspase-9 is phosphorylated by Akt and that its protease activity is reduced ...

Ceramide induces neuronal apoptosis through the caspase-9/caspase-3 pathway

Biochemical and Biophysical Research Communications, 2002
C(2)-ceramide, a cell-permeable analog of ceramide, caused cell death in cultured rat cortical neuronal cells. C(2)-ceramide-induced neuronal loss was accompanied by upregulation of caspase-3 activity, measured by cleavage of its fluorogenic substrate Ac-DEVD-AMC.

Caspase-9

The International Journal of Biochemistry & Cell Biology, 2000
Caspase-9 is a member of caspase family of cysteine proteases that have been implicated in apoptosis and cytokine processing. When cells receive apoptotic stimuli, mitochondria releases cytochrome c which then binds to Apaf-1, the mammalian Ced-4 homologue, together with dATP.

Delineation of the caspase-9 signaling cascade

Apoptosis, 2007
In the intrinsic apoptosis pathway, mitochondrial disruption leads to the release of multiple apoptosis signaling molecules, triggering both caspase-dependent and -independent cell death. The release of cytochrome c induces the formation of the apoptosome, resulting in caspase-9 activation.

Expression Analysis of caspase-6, caspase-9 and BNIP3 in Prostate Cancer

Tumori Journal, 2010
Aims Altered regulation of cell death is a feature of human cancer. The aim of this study was to explore whether the expression of the proapoptotic proteins caspase-6, caspase-9, and Bcl-2/adenovirus E1B-19kDa-interacting protein3 (BNIP3) is altered in prostate cancers.

Caspase 9 is decreased in psoriatic epidermis

Acta Histochemica, 2006
Psoriasis is a proliferative and inflammatory disease of the skin. Caspase 9 is responsible for initiating the caspase activation cascade during apoptosis. Apoptosis is a physiological mechanism of homeostasis and development, and caspases are the executioners of apoptosis.
