CASP9 — UCN
Text-mined interactions from Literome
Tang et al., Biochem Pharmacol 2000
(Leukemia) :
Enforced expression of full-length Bcl-2 significantly protected cells ( at 24 hr ) from
ara-C/UCN-01 induced caspase activation and apoptosis, but was ineffective in preventing loss of Deltapsi ( m ) and cytochrome c release
Wang et al., Mol Pharmacol 2003
(Leukemia, Myeloid) :
Whereas bryostatin 1 and
UCN-01 both markedly
enhanced ara-C induced mitochondrial injury ( e.g., cytochrome c and Smac/DIABLO release, loss of mitochondrial membrane potential ),
caspase activation, and apoptosis, ectopic expression of an N-terminal loop deleted Bcl-2 mutant protein protected cells from ara-C/UCN-01- but not ara-C/bryostatin 1-mediated lethality
Chan et al., Anticancer Drugs 2003
(Colonic Neoplasms) :
In addition to Bcl-xL and p38 MAPK,
UCN-01 also
increased both
caspase-3 and peroxisome proliferator activated receptor gamma protein levels
Dudgeon et al., Mol Cancer Ther 2010
:
Deficiency in PUMA abrogated
UCN-01 induced apoptosis,
caspase activation, and mitochondrial dysfunction, and rendered UCN-01 resistance in a clonogenic assay, whereas elevated PUMA expression or a BH3 mimetic sensitized UCN-01 induced apoptosis
