Open AccessHIV-1 protease cleaves the serine-threonine kinases RIPK1 and RIPK2
HIV-1 protease (PR) is essential for viral infectivity as it cleaves Gag and Gag-Pol polyprotein precursors during viral maturation. Recent evidence suggests that cellular proteins can also be cleaved by PR, p...

Roles of Apoptosis-Regulating Bcl-2 Family Genes in AML
Among the cardinal features of malignancy is abrogation of cell death mechanisms, thus endowing cancer and leukemia cells with a selective survival advantage relative to normal cells. Genetic and epigenetic le...

Systematic analysis and validation of differential gene expression in ovarian serous adenocarcinomas and normal ovary
Cancer of the ovary confers the worst prognosis among women with gynecological malignancies, primarily because most ovarian cancers are diagnosed at late stage. Hence, there is a substantial need to develop ne...

The Patched dependence receptor triggers apoptosis through a DRAL–caspase-9 complex
Shh acts as a survival factor and in its absence its receptor, Patched, induces cell death by recruiting a caspase-activating complex formed by the adaptor protein DRAL, the CARD domain containing proteins TUC...

Salmonella typhimurium engineered to produce CCL21 inhibit tumor growth
Intravenously-applied bacteria tend to accumulate in tumors and can sporadically lead to tumor regression. Systemic administration of attenuated Salmonella typhimurium is safe and has shown no significant adverse...

BLOC1S2 interacts with the HIPPI protein and sensitizes NCH89 glioblastoma cells to apoptosis
The HIPPI (HIP-1 protein interactor) protein is a multifunctional protein that is involved in the regulation of apoptosis. The interaction partners of HIPPI include HIP-1 (Huntingtin-interacting protein-1), Ap...

Yeast and Mammalian Two-Hybrid Systems for Studying Protein-Protein Interactions
An important step in the analysis of protein function is identification of the interaction partners of each protein. The two-hybrid system has been widely used to identify and explore protein-protein interacti...

Yeast and apoptosis
Even though yeast lack much of the molecular machinery that is responsible for apoptosis in metazoans, they can be a powerful tool in apoptosis research. The ectopic expression of several animal apoptosis prot...

Apoptosis and cancer: When BAX is TRAILing away
The development of anticancer therapies that target apoptosis pathways may be hampered by resistance of certain tumor cells to death signals. New findings show that tumor cells lacking the pro-apoptotic protei...

Oocyte apoptosis is suppressed by disruption of the acid sphingomyelinase gene or by sphingosine -1-phosphate therapy
The time at which ovarian failure (menopause) occurs in females is determined by the size of the oocyte reserve provided at birth, as well as by the rate at which this endowment is depleted throughout post-nat...

Changes in intramitochondrial and cytosolic pH: early events that modulate caspase activation during apoptosis
Mitochondria trigger apoptosis by releasing caspase activators, including cytochrome c (cytC). Here we show, using a pH-sensitive green fluorescent protein (GFP), that mitochondria-dependent apoptotic stimuli (su...

Mitochondrial control of cell death
In many instances, permeabilization of mitochondrial membranes is a rate-limiting step of apoptotic or necrotic cell demise. This has important consequences for the pathophysiology of cell death, as well as fo...

Survivin’ cell-separation anxiety
Survivin, a cell-death inhibitor, localizes to the spindles of mitotic cells, and its absence causes both a failure in cell division and induction of cell death. Might survivin link the control of cell death w...
