The functional domains for Bax∆2 aggregate-mediated caspase 8-dependent cell death.Bax∆2 is a functional pro-apoptotic Bax isoform having alterations in its N-terminus, but sharing the rest of its sequence with Baxα. Bax∆2 is unable to target mitochondria due to the loss of helix α1. Instead, it forms cytosolic aggregates and activates caspase 8. However, the functional domain(s) responsible for BaxΔ2 behavior have remained elusive. Here we show that disruption of helix α1 makes Baxα mimic the behavior of Bax∆2. However, the other alterations in the Bax∆2 N-terminus have no significant impact on aggregation or cell death. We found that the hallmark BH3 domain is necessary but not sufficient for aggregation-mediated cell death. We also noted that the core region shared by Baxα and Bax∆2 is required for the formation of large aggregates, which is essential for BaxΔ2 cytotoxicity. However, aggregation by itself is unable to trigger cell death without the C-terminus. Interestingly, the C-terminal helical conformation, not its primary sequence, appears to be critical for caspase 8 recruitment and activation. As Bax∆2 shares core and C-terminal sequences with most Bax isoforms, our results not only reveal a structural basis for Bax∆2-induced cell death, but also imply an intrinsic potential for aggregate-mediated caspase 8-dependent cell death in other Bax family members.

Plumbagin enhances TRAIL-induced apoptosis of human leukemic Kasumi‑1 cells through upregulation of TRAIL death receptor expression, activation of caspase-8 and inhibition of cFLIP.Although the patients with t(8;21) acute myeloid leukemia (AML) have a favorable prognosis compared with other non-acute promyelocytic leukemia AML patients, only ~50% patients with this relatively favorable subtype can survive for 5 years and refractory/relapse is common in clinical practice. So it is necessary to find novel agents to treat this type of AML. In this study, the effects and the mechanisms of plumbagin and recombinant soluble tumor necrosis factor‑α-related apoptosis-inducing ligand (rsTRAIL) on leukemic Kasumi‑1 cells were primarily investigated. Plumbagin and/or rsTRAIL could significantly inhibit the growth of Kasumi‑1 cells and induce apoptosis in vitro and in vivo. Plumbagin enhanced TRAIL-induced apoptosis of Kasumi‑1 cells in association with mitochondria damage, caspase activation, upregulation of death receptors (DRs) and decreased cFLIP expression. The effects of plumbagin on the expression of DR5, Bax and cFLIP could be partially abolished by the reactive oxygen species (ROS) scavenger NAC. Glutathione (GSH) depletion by plumbagin increased the production of ROS. In vivo, there was no obvious toxic pathologic change in the heart, liver and kidney tissues in any of the groups. Comparing with the control mice, a significantly increased number of apoptotic cells were observed in the combined treated mice by flow cytometry. Plumbagin also increased the expression of DR4 and DR5 in cells of xenograft tumors. Collectively, our results suggest that both plumbagin and rsTRAIL could be used as a single agent or synergistical agents to induce apoptosis of leukemic Kasumi‑1 cells in vitro and in vivo.

Recombinant human brain-derived neurotrophic factor prevents neuronal apoptosis in a novel in vitro model of subarachnoid hemorrhage.Subarachnoid hemorrhage (SAH) is a hemorrhagic stroke with high mortality and morbidity. An animal model for SAH was established by directly injecting a hemolysate into the subarachnoid space of rats or mice. However, the in vitro applications of the hemolysate SAH model have not been reported, and the mechanisms remain unclear. In this study, we established an in vitro SAH model by treating cortical pyramidal neurons with hemolysate. Using this model, we assessed the effects of recombinant human brain-derived neurotrophic factor (rhBDNF) on hemolysate-induced cell death and related mechanisms. Cortical neurons were treated with 10 ng/mL or 100 ng/mL rhBDNF prior to application of hemolysate. Hemolysate treatment markedly increased cell loss, triggered apoptosis, and promoted the expression of caspase-8, caspase-9, and cleaved caspase-3. rhBDNF significantly inhibited hemolysate-induced cell loss, neuronal apoptosis, and expression of caspase-8, caspase-9, and cleaved caspase-3. Our data revealed a previously unrecognized protective activity of rhBDNF against hemolysate-induced cell death, potentially via regulation of caspase-9-, caspase-8-, and cleaved caspase-3-related apoptosis. This study implicates that hemolysate-induced cortical neuron death represents an important in vitro model of SAH.

Antitumor activity of interferon-β1a in hormone refractory prostate cancer with neuroendocrine differentiation.Type I interferons (IFN-α and IFN-β) are a class of cytokines that exert several biological activities, such as modulation of cell proliferation and differentiation and of the immune system. Although these cytokines interact with a common receptor complex, IFN-β showed a more potent antitumor activity than IFN-α in several tumor models. New recombinant human IFN-β products, such as IFN-β1a and IFN-β1b, have been produced in order to improve the stability and bioavailability of natural IFN-β. In this report, we analyzed the effects of recombinant IFN-β1a on the cell proliferation of two human androgen-resistant prostate cancer cell lines with neuroendocrine differentiation (DU-145, PC-3) and related mechanisms of action.

Sensitization of glycoengineered interferon-β1a-resistant cancer cells by cFLIP inhibition for enhanced anti-cancer therapy.In this study, we examined the molecular mechanism underlying the resistance of cancer cells to R27T, a glycoengineered version of recombinant human interferon (IFN)-β1a, and sought to overcome R27T resistance through combination therapy. R27T has been shown to induce anti-proliferation and apoptosis in human OVCAR-3 and MCF-7 cells, but not in HeLa cells. R27T treatment increased caspase-8 activity and the consequent cleavage of caspase-8 and -3 in R27T-sensitive OVCAR-3 cells, but not in R27T-resistant HeLa cells. Conversely, R27T increased the expression of cellular FLICE-like inhibitory protein (cFLIP) in HeLa cells, but not in OVCAR-3 cells. The sensitization of HeLa cells with cFLIP small interfering RNA or 4,5,6,7-tetrabromobenzotriazole (TBB, an inhibitor of casein kinase-2) facilitated R27T-induced caspase activation, and consequently apoptosis. In OVCAR-3-xenografted mice, intraperitoneal administration of R27T showed 2.1-fold higher anti-tumor efficacy than did the control vehicle. The combined administration of R27T and TBB showed the greatest anti-tumor effect in HeLa tumor-bearing mice, reducing the relative tumor volume by 35.7% compared to that in R27T-treated mice. Taken together, our results suggest that R27T has potential as an anti-cancer drug, and combination therapy with cFLIP inhibitors may be an effective strategy for overcoming R27T resistance.

Dual role of interleukin-1β in islet amyloid formation and its β-cell toxicity: Implications for type 2 diabetes and islet transplantation.Islet amyloid, formed by aggregation of human islet amyloid polypeptide (hIAPP), contributes to β-cell failure in type 2 diabetes, cultured and transplanted islets. We previously showed that biosynthetic hIAPP aggregates induce β-cell Fas upregulation and activation of the Fas apoptotic pathway. We used cultured human and hIAPP-expressing mouse islets to investigate: (1) the role of interleukin-1β (IL-1β) in amyloid-induced Fas upregulation; and (2) the effects of IL-1β-induced β-cell dysfunction on pro-islet amyloid polypeptide (proIAPP) processing and amyloid formation.

Tumor suppressor BLU promotes TRAIL-induced apoptosis by downregulating NF-κB signaling in nasopharyngeal carcinoma.A putative tumor suppressor BLU mapped on the chromosomal 3p21 region, is frequently lost in human tumors including nasopharyngeal carcinoma (NPC). To explore the underlying mechanism of tumor suppression by BLU, its potential to promote apoptosis induced by TRAIL, an effector molecule elaborated by natural killer-T (NKT) cells was investigated. BLU was re-expressed in NPC-derived HNE1 cells by recombinant adenoviral infection and the cells were challenged with recombinant TRAIL. The growth inhibition of BLU was assayed and apoptosis was examined by flow cytometry-based tetramethylrhodamine ethyl ester (TMRE) and annexin V staining, cleavage of pro-caspase-8 and poly ADP ribose polymerase (PARP). The modulation of NF-κB pathway by BLU was evaluated by the reporter activity and estimation of the level of the molecules involved such as IKKalpha, p65 NF-κB, as well as NF-κB induced anti-apoptotic factors cFLIPL and cIAP2. The expression of BLU exerted in vitro and in vivo growth inhibitory effect and promoted TRAIL-induced apoptosis. This phenomenon was validated by FACS-based assays of mitochondrial membrane potential (BLU vs. Vector 87.8% ± 7.7% and 72.1%±6.7% at 6h exposure to TRAIL) and phosphatidylserine turnover (BLU vs. vector: 28.7%±2.9% and 22.6%±2.5%), as well as, enhanced caspapse-8 cleavage. Similar with the findings that BLU promotes chemotherapeutic agent-induced apoptosis, it also augmented death receptor-induced pathway through NF-κB pathway inhibition. In conclusion, BLU suppressed tumor formation by strengthening the antitumor immunity.

Heterologous expression and functional characterization of phytaspase, a caspase-like plant protease.Following the cloning and expression of tobacco (Nicotiana tabacum) phytaspase gene in Escherichia coli BL21, the recombinant protease was purified by affinity chromatography for further characterization. Circular dichroism (CD) spectroscopy and in silico analysis revealed structural similarities of recombinant phytaspase with other plant serine-proteases. Molecular docking studies showed favourable binding of synthetic peptide substrate for caspase 8 (Ac-VETD-AMC) to the reactive pocket of recombinant phytaspase indicating its potential in assessing functional activity of recombinant phytaspase. In silico findings were supported by caspase 8-like activity of purified phytaspase demonstrated in vitro. The Michaelis constant (KM) and specificity constant (kcat/KM) of phytaspase for hydrolyzing Ac-VETD-AMC were found to be 1.587μM and 4.67×10(3)M(-1)min(-1), respectively. Transient expression of phytaspase in lung epithelial adenocarcinoma cells (A549) resulted in reduced IC50 value of doxorubicin. This is the first report of functional expression of mature phytaspase in bacterial system as well as its transfection to sensitize A549 cells at lower doxorubicin concentration.
