Text-mined interactions from Literome
Matta et al., Cancer Biol Ther 2002

MRITalpha1/cFLIP ( L ) expression is decreased during drug induced apoptosis and exogenous expression of MRITalpha1/cFLIP ( L )
delays the activation of
caspase-8 and -3 during drug- induced apoptosis
Madge et al., J Biol Chem 2003
:
Cycloheximide but not LY294002 decreases expression of
c-FLIP ( cellular FLICE inhibitory protein ), an
inhibitor of
caspase-8 activation
Chen et al., Biochem Biophys Res Commun 2003
:
In addition, angiostatin also activated the Fas mediated apoptotic pathway in part via up-regulation of FasL mRNA, down-regulation of
c-Flip , and
activation of
caspase 3
Vier et al., Mol Immunol 2004
:
As a
consequence of
caspase-activation ,
c-FLIP-levels in the cytosol decreased
Hasegawa et al., J Biol Chem 2005
(Inflammation) :
ASC mediated NF-kappaB activation leading to interleukin-8 production requires
caspase-8 and is
inhibited by
CLARP ... This response required
caspase-8 , and was
suppressed by
CLARP/FLIP , an inhibitor of caspase-8
Du et al., Kidney Int 2005
:
Consistent with this, IL-2 but not IFN-gamma was found to decrease mRNA and protein expression of
c-FLIP , an endogenous
caspase-8 inhibitor in murine TECs ... Overexpression of
c-FLIP in TECs ( CS3.7-FLIP )
blocked apoptosis and
caspase-8 activation with both IFN-gamma and IL-2
Longley et al., Oncogene 2006
(Colorectal Neoplasms) :
c-FLIP inhibits
caspase 8 activation and apoptosis mediated by death receptors such as Fas and DR5
Chang et al., Cell 2006
(Liver Failure, Acute) :
Here we show that TNFalpha mediated JNK activation accelerates turnover of the NF-kappaB induced antiapoptotic protein
c-FLIP , an
inhibitor of
caspase-8
Saito et al., J Virol 2006
:
A decrease in endogenous
c-FLIP by specific small interfering RNA
induced TNF-alpha mediated apoptotic cell death and
caspase-8 activation
Huber et al., Immunology 2006
(Coxsackievirus Infections...) :
c-FLIP also heterodimerizes with and
activates caspase-8 , resulting in increased death of T cells and a selection of a T helper 2 cytokine profile
da Silva Correia et al., J Biol Chem 2007
:
Furthermore, overexpression of
CLARP , a specific
caspase 8
inhibitor , completely blocked cleavage of CSN6
Wang et al., Cell Signal 2007
(Pancreatic Neoplasms) :
These results indicate the
role of
c-FLIP and RIP in
caspase-8 inhibition and thus TRAIL resistance
Dash et al., Exp Cell Res 2007
:
Inhibition of
cFLIP recruitment to the DISC
leads to increased activation of
caspase 8 and subsequently to apoptosis
Hinshaw-Makepeace et al., Eur J Immunol 2008
:
Here we show that, in contrast to c-FLIP ( L ),
c-FLIP ( S )
inhibits activation of
caspase-8 in T cells, and consequently reduces recruitment of MALT1 and Bcl-10 to the active caspase complex
Roy et al., Proc Natl Acad Sci U S A 2008
:
This molecular role for caspase-12 appears to be akin to the
role of
cFLIP in regulating
caspase-8 in the extrinsic cell death pathway ; however, unlike cFLIP/Usurpin, we demonstrate here that caspase-12 is catalytically competent
Wang et al., Cell 2008
:
Moreover, Smac mimetic induced
caspase-8 activation is not
blocked by endogenous
c-FLIP
Luo et al., Cancer Lett 2008
:
c-FLIP inhibits
caspase-8 activation and cell apoptosis mediated by death receptors
Kim et al., J Cell Biochem 2008
(Kidney Neoplasms) :
cFLIP inhibits
caspase 8 recruitment and processing at the death inducing signaling complex ( DISC ), which is known to inhibits apoptosis mediated by death receptors such as Fas and death receptor 5 (DR5) as well as apoptosis mediated by anticancer therapeutic drugs
Ivanov et al., Cancer Res 2009
(Melanoma) :
Pretreatment of several melanoma lines just before gamma-irradiation with the inhibitor of ATM kinase KU-55933 suppressed p53 and nuclear factor-kappaB (NF-kappaB) activation but notably increased radiation induced DR5 surface expression, down-regulated
cFLIP (
caspase-8 inhibitor ) levels, and substantially enhanced exogenous TRAIL induced apoptosis
Klapproth et al., Blood 2009
(Burkitt Lymphoma...) :
NF-kappaB up-regulates Fas and predisposes to Fas induced cell death, which is
caspase-8 mediated and can be
prevented by
CFLAR overexpression
Eeva et al., Scand J Immunol 2009
:
Fas induced apoptosis was dependent on the caspase-8 activation, since the overexpression of
c-FLIP ( long ), a natural
inhibitor of
caspase-8 activation, blocked apoptosis induced by Fas
Tiwary et al., PloS one 2010
:
Knockdown studies using siRNAs to TRAIL, DR5, JNK and CHOP as well as chemical inhibitors of ER stress and caspase-8 showed that : i ) alpha-TEA activation of DR5/caspase-8 induces an ER stress mediated JNK/CHOP/DR5 positive amplification loop ; ii ) alpha-TEA downregulation of c-FLIP ( L ) protein levels is mediated by JNK/CHOP/DR5 loop via a JNK dependent Itch E3 ligase ubiquitination that further serves to enhance the JNK/CHOP/DR5 amplification loop by preventing
c-FLIP 's
inhibition of
caspase-8 ; and ( iii ) alpha-TEA downregulation of Bcl-2 is mediated by the ER stress dependent JNK/CHOP/DR5 signaling
Liu et al., World J Gastroenterol 2011
(Stomach Neoplasms) :
In vivo, LY294002 inhibited oxaliplatin induced activation of Akt and NF?B, and increased oxaliplatin induced expression of FasL, inhibition of
c-FLIP ( S ), and
activation of
caspase-8 , Bid, and caspase-3
Choi et al., Chem Biol Interact 2011
(Carcinoma, Renal Cell...) :
Cafestol induced apoptosis is associated with the reduction of mitochondrial membrane potential ( MMP ),
activation of
caspase 3, cytochrome c release, and down-regulation of anti-apoptotic proteins ( Bcl-2, Bcl-xL, Mcl-1 and
cFLIP )
Chen et al., J Leukoc Biol 2011
:
Furthermore, tmTNF-a led to
activation of
caspase-8 by dissociation of cFLIP from TNFR2 and inhibition of the
cFLIP expression
Bangert et al., Oncogene 2012
(Glioblastoma) :
This leads to decreased recruitment of cFLIP ( L ) and
cFLIP ( S ) and increased
activation of
caspase-8 to the TRAIL death inducing signaling complex, resulting in enhanced cleavage of caspase-8, -9 and -3 and caspase dependent apoptosis
Shi et al., Bioinformatics 2013
:
cFLIP , an
inhibitor of
caspase-8 activation, was up-regulated briefly after 30 min of LY30 treatment, followed by a significant down-regulation over prolonged exposure
Scaffidi et al., J Biol Chem 1999
:
In stably transfected BJAB cells,
c-FLIP blocks
caspase-8 activation at the DISC and thereby inhibits CD95 mediated apoptosis
