p27Kip1 induces drug resistance by preventing apoptosis upstream of cytochrome c release and procaspase-3 activation in leukemic cells. (1/311)

The cyclin-dependent kinase inhibitor p27Kip1 has been implicated as a drug resistance factor in tumor cells grown as spheroids or confluent monolayers. Here, we show that p27Kip1 overexpression also induces resistance to drug-induced apoptosis and cytotoxicity in human leukemic cells growing in suspension. The anti-apoptotic effect of p27Kip1 is not restricted to DNA-damaging agents but extends to the tubulin poison vinblastin, agonistic anti-Fas antibodies and macromolecule synthesis inhibitors. To further identify at which level this protein interferes with the cell death pathway, we investigated its influence on caspase activation and mitochondrial changes. Exposure of mock-transfected U937 cells to 50 microm etoposide activates procaspase-3 and the long isoform of procaspase-2 and induces mitochondrial potential decrease and cytochrome c release from mitochondria to the cytosol. All these events are prevented by p27Kip1 overexpression. p27Kip1 does not modulate Bcl-2, Bcl-X(L), Mcl-1 and Bax protein level in leukemic cells but suppresses Mcl-1 expression decrease observed in mock-transfected U937 cells undergoing etoposide-induced cell death. We conclude that p27Kip1 prevents cell death upstream of the final pathway common to many apoptotic stimuli that involves cytochrome c release from mitochondria and activation of downstream caspases.  (+info)

Bcl-2 regulates a caspase-3/caspase-2 apoptotic cascade in cytosolic extracts. (2/311)

Apoptosis is accompanied by the activation of a number of apoptotic proteases (caspases) which selectively cleave specific cellular substrates. Caspases themselves are zymogens which are activated by proteolysis. It is widely believed that 'initiator' caspases are recruited to and activated within apoptotic signalling complexes, and then cleave and activate downstream 'effector' caspases. While activation of the effector caspase, caspase-3, has indeed been observed as distal to activation of several different initiator caspases, evidence for a further downstream proteolytic cascade is limited. In particular, there is little evidence that cellular levels of caspase-3 that are activated via one pathway are sufficient to cleave and activate other initiator caspases. To address this issue, the ability of caspase-3, activated upon addition to cytosolic extracts of cytochrome c, to cause cleavage of caspase-2 was investigated. It was demonstrated that cleavage of caspase-2 follows, and is dependent upon, activation of caspase-3. Moreover, the activation of both caspases was inhibited by Bcl-2. Together, these data indicate that Bcl-2 can protect cells from apoptosis by acting at a point downstream from release of mitochondrial cytochrome c, thereby preventing a caspase-3 dependent proteolytic cascade.  (+info)

Targeted disruption of caspase genes in mice: what they tell us about the functions of individual caspases in apoptosis. (3/311)

Cysteine proteases of the caspase family are crucial mediators of apoptosis. All mammalian cells contain a large number of caspases. Although many caspases are activated in a cell committed to apoptosis, recent data from caspase gene knockout mice suggest that individual caspases may be involved in the cell and stimulus-specific pathways of cell death. The gene disruption studies also establish the functional hierarchy between two structurally distinct classes of caspases. The present review discusses these recent findings and elaborates on how these mutant mouse models have helped the understanding of the mechanisms that govern programmed cell death in the immune and other systems.  (+info)

CIPER, a novel NF kappaB-activating protein containing a caspase recruitment domain with homology to Herpesvirus-2 protein E10. (4/311)

We have identified and characterized CIPER, a novel protein containing a caspase recruitment domain (CARD) in its N terminus and a C-terminal region rich in serine and threonine residues. The CARD of CIPER showed striking similarity to E10, a product of the equine herpesvirus-2. CIPER formed homodimers via its CARD and interacted with viral E10 but not with several apoptosis regulators containing CARDs including ARC, RAIDD, RICK, caspase-2, caspase-9, or Apaf-1. Expression of CIPER induced NF-kappaB activation, which was inhibited by dominant-negative NIK and a nonphosphorylable IkappaB-alpha mutant but not by dominant-negative RIP. Mutational analysis revealed that the N-terminal region of CIPER containing the CARD was sufficient and necessary for NF-kappaB-inducing activity. Point mutations in highly conserved residues in the CARD of CIPER disrupted the ability of CIPER to activate NF-kappaB and to form homodimers, indicating that the CARD is essential for NF-kappaB activation and dimerization. We propose that CIPER acts in a NIK-dependent pathway of NF-kappaB activation.  (+info)

DRONC, an ecdysone-inducible Drosophila caspase. (5/311)

Caspases play an essential role in the execution of programmed cell death in metazoans. Although 14 caspases are known in mammals, only a few have been described in other organisms. Here we describe the identification and characterization of a Drosophila caspase, DRONC, that contains an amino terminal caspase recruitment domain. Ectopic expression of DRONC in cultured cells resulted in apoptosis, which was inhibited by the caspase inhibitors p35 and MIHA. DRONC exhibited a substrate specificity similar to mammalian caspase-2. DRONC is ubiquitously expressed in Drosophila embryos during early stages of development. In late third instar larvae, dronc mRNA is dramatically up-regulated in salivary glands and midgut before histolysis of these tissues. Exposure of salivary glands and midgut isolated from second instar larvae to ecdysone resulted in a massive increase in dronc mRNA levels. These results suggest that DRONC is an effector of steroid-mediated apoptosis during insect metamorphosis.  (+info)

Analysis of apoptosis and expression of bcl-2 gene family members in the human and baboon ovary. (6/311)

Recent data support a role for apoptosis, under tight regulatory control by bcl-2, oxidative stress response, tumor suppressor, and CASP gene family members, in mediating granulosa cell demise during follicular atresia in the rodent and avian ovary. Herein we evaluated the occurrence of apoptosis in the human and baboon ovary relative to follicular health status, and analyzed expression of several cell death genes in these tissues. In situlocalization of DNA strand breaks in fixed human and baboon ovarian tissue sections indicated that apoptosis was essentially restricted to granulosa cells of atretic antral follicles. Biochemical analysis of DNA oligonucleosomes in individual follicles isolated from baboon ovaries during the ovulatory phase revealed the presence of apoptotic DNA fragments in subordinate but not dominant follicles, thus substantiating the in situ labeling studies. Messenger RNA transcripts encoded by the bax death susceptibility gene, the bcl-xlong survival gene, the bcl-xshort pro-apoptosis gene, the p53 tumor suppressor gene, and two members of the CASP gene family (CASP-2/Ich-1, CASP-3/CPP32), were detected by Northern blot analysis of total RNA prepared either from human ovaries or from Percoll-purified granulosa-lutein cells obtained from patients undergoing assisted reproductive technologies. Lastly, immunohistochemical localization of the BAX death-susceptibility protein in the human ovary revealed abundant expression in granulosa cells of early atretic follicles, whereas BAX protein was extremely low or non-detectable in healthy or grossly-atretic follicles. We conclude that apoptosis occurs during, and is probably responsible for, folicular atresia in the human and baboon ovary. Moreover, apoptosis in the human ovary is likely controlled by altered expression of the same cohort of cell death regulatory factors recently implicated as primary determinants of apoptosis induction or suppression in the rodent ovary.  (+info)

Extended therapeutic window for caspase inhibition and synergy with MK-801 in the treatment of cerebral histotoxic hypoxia. (7/311)

In rats, striatal histotoxic hypoxic lesions produced by the mitochondrial toxin malonate resemble those of focal cerebral ischemia. Intrastriatal injections of malonate induced cleavage of caspase-2 beginning at 6 h, and caspase-3-like activity as identified by DEVD biotin affinity-labeling within 12 h. DEVD affinity-labeling was prevented and lesion volume reduced in transgenic mice overexpressing BCL-2 in neuronal cells. Intrastriatal injection of the tripeptide, N-benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone (zVAD-fmk), a caspase inhibitor, at 3 h, 6 h, or 9 h after malonate injections reduced the lesion volume produced by malonate. A combination of pretreatment with the NMDA antagonist, dizocilpine (MK-801), and delayed treatment with zVAD-fmk provided synergistic protection compared with either treatment alone and extended the therapeutic window for caspase inhibition to 12 h. Treatment with cycloheximide and zVAD-fmk, but not with MK-801, blocked the malonate-induced cleavage of caspase-2. NMDA injections alone resulted in a weak caspase-2 cleavage. These results suggest that malonate toxicity induces neuronal death by more than one pathway. They strongly implicate early excitotoxicity and delayed caspase activation in neuronal loss after focal ischemic lesions and offer a new strategy for the treatment of stroke.  (+info)

Role of caspases and possible involvement of retinoblastoma protein during TGFbeta-mediated apoptosis of human B lymphocytes. (8/311)

In this study, we investigated the involvement of caspases in TGFbeta-induced apoptosis in human B cells. Our results show that TGFbeta-mediated nuclear fragmentation, observed in the Epstein-Barr virus-negative Burkitt's Lymphoma cell line BL41, was abolished in the presence of the tripeptide caspase inhibitor zVAD-fmk or the specific caspase-3 inhibitor DEVD-fmk. Other apoptotic manifestations such as cell shrinkage, surface phosphatidylserine expression and chromatin condensation were strongly inhibited by zVAD-fmk but only partially by DEVD-fmk. This suggests that other caspases in addition to caspase-3 control these apoptotis-associated features. Specific activation of caspase-3 during TGFbeta-induced apoptosis was demonstrated by the DEVD-fmk-sensitive expression of the active p17 subunit of caspase-3 and by in vivo cleavage of PARP. In addition, TGFbeta treatment of BL41 promoted the expression of both dephosphorylated and truncated forms of the retinoblastoma protein. Inhibition of caspase-3 activity abolished both nuclear fragmentation and expression of the truncated retinoblastoma protein, without modifying the G1 cell cycle arrest induced by TGFbeta. Our data thus demonstrate that TGFbeta-induced apoptosis of lymphoma B lymphocytes is dependent on caspase activation and involves caspase-dependent cleavage of the retinoblastoma protein.  (+info)

Use and dose of Nolvadex. To treat breast cancer, patients are recommended to take a tablet of Nolvadex 20 mg 1-2 times per day. If the side effects are absent, a one-time dose of Nolvadex may be increased up to 40 mg.. To treat cancer of kidneys or endometrium, patients are also prescribed a tablet of Nolvadex 20-30 mg 1-2 times per day.. A therapeutic effect is kept only during the prolonged treatment. The action of a tablet of Nolvadex 20 mg lasts for 12 to 20 hours, and therefore if you forgot to take a dose, there is an expectancy of the restored activity of the estrogenic receptors and a reduction of the treatment efficiency.. The treatment of tumors may take 1 to 5 years depending on the sensitivity to Nolvadex. In case of the prolonged treatment, a tolerance of Nolvadex may be developed. If a growth of the cancerous cells is restored during the medical study because of the use of Nolvadex, the treatment is terminated.. Recommendations for the use. ...
Obesity is associated with low-grade chronic inflammation without bacterial or viral infection, but the triggers and molecular mechanisms that lead to obesity-associated metabolic inflammation remain to be further explored. Although recent studies demonstrated palmitate triggered thioglycollate-elicited macrophage death under the stimulation of Gram-negative bacteria-derived LPS (39, 40), it did not explain the sterile inflammation associated with obesity, and it also raised concerns regarding physiology and activated status of these thioglycollate-activated macrophages (41). In this article, we report that when various dietary FAs were uptaken by stable macrophage cell lines or primary BMMs, only sFAs (e.g., PA, SA) were metabolized to produce Cers to induce macrophage cell death. Most importantly, we identified A-FABP as a new molecular sensor in mediating excess sFA-induced Cer production and in promoting macrophage cell death, thus contributing to the sterile chronic inflammation in ...
Apollon, also called Baculoviral IAP Repeat-Containing Protein 6 (BIRC6) or Baculoviral IAP Repeat-containing Ubiquitin Conjugating Enzyme (BRUCE), is an anti-apoptotic protein belonging to the IAP family, which consists of eight members. The genes of this family render cancer cells insensitive to apoptotic stimulation. The aim of the present study was to investigate and assess the role of small interference RNA (siRNA) in the regulation of Apollon gene expression in four different human cancerous cell lines; breast cancer (MCF-7), cervical cancer (HeLa), colon cancer (CaCo-2) and hepatocellular carcinoma (HepG-2). Lipofection was carried out to introduce the Apollon-specific siRNA into the cancerous cells and the Apollon expression levels were determined using RT-PCR. Trypan blue assay was conducted to assess the integrity of the cell membranes after being transfected. 3-(4, 5-dimethylthiazol-2-yl)-2-5- Diphenyl tetrazolium bromide (MTT) assay was also implemented to assess the cell viability ...
Caspase-3 plays a key role in initiation of cellular events during the apoptotic process. PromoKines Caspase-3 and Caspase-7 Immunoassay Kits allow quantification of the specific activity of caspase-3 and -7, respectively. Since caspase-3 and -7 share the same target substrate sequence (DEVD), it is difficult to differentiate the cleavage activity attributed by these two caspases in vitro. Thus, the assays utilize caspase-3 or -7 specific antibodies to capture the activated caspase-3 or -7 in cell lysate. Specific activity of caspase-3 or -7 can then be analyzed using the common caspase-3/7 substrate DEVD-AFC. The assay system ensures absolute specific detection of only caspase-3 or caspase-7 activity in apoptotic samples. Other caspases and non-specific proteases are not detected.. ...

Thus it is a potential target for neurodegenerative drug development. In the present study we report on the biochemistry and structure of caspase-6. As an effector caspase, caspase-6 is a constitutive dimer independent of the maturation state of the enzyme. The ligand-free structure shows caspase-6 in a partially mature but latent conformation. The cleaved inter-domain linker remains partially inserted in the central groove of the dimer, as observed in other caspases. However, in contrast with the structures of other caspases, not only is the catalytic machinery misaligned, but several structural elements required for substrate recognition are missing. Most importantly, residues forming a short anti-parallel β-sheet abutting the substrate in other caspase ...

Salmonella induces programmed cell death in macrophages by complex mechanisms that involve distinct pathways and require the bacterial TTSS encoded in the pathogenicity island 1 (SPI-1 TTSS). One death pathway, which results in rapid macrophage death with features of necrosis, is dependent on caspase-1 and the SPI-1 TTSS-secreted protein SipB (Hersh et al., 1999; Brennan and Cookson, 2000; Jesenberger et al., 2000). However, macrophages from caspase-1−/− mice also undergo programmed cell death, although with delayed kinetics and different morphological features. Here, we have described another death pathway induced by Salmonella that is independent of caspase-1. A systematic bacterial genetic analysis led us to conclude that this cell death pathway is also dependent on SipB, a protein with membrane fusion activity that is delivered into host cells by the SPI-1 TTSS. This analysis was complicated by the known dual function of SipB, which acts both as an effector of virulence within cells and ...
