Abstract
Malignant melanoma is considered the most aggressive skin carcinoma with invasive growth patterns. Triptolide (TPL) possesses various biological and pharmacological activities involved in cancer treatment. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) can induce cancer cell apoptosis by binding to DR5 highly expressed on cancer cells. Exosomes are natural nanomaterials with low immunogenicity, nontoxicity, and excellent biocompatibility and have been extensively used as emerging delivery vectors for diverse therapeutic cargos. Herein, a delivery system based on TRAIL-engineered exosomes (TRAIL-Exo) for loading TPL for targeted therapy against malignant melanoma is proposed and systematically investigated. Our results showed that TRAIL-Exo/TPL could improve tumor targetability, enhance cellular uptake, inhibit proliferation, invasion, and migration, and induce apoptosis of A375 cells through activating the extrinsic TRAIL pathway and the intrinsic mitochondrial pathway in vitro. Moreover, intravenous injection of TRAIL-Exo/TPL significantly suppressed tumor progression and reduced the toxicity of TPL in the melanoma nude mouse model. Together, our research presents a novel strategy for high-efficiency exosome-based drug-delivery nanocarriers and provides an alternative dimension for developing a promising approach with synergistic therapeutic efficacy and targeting capacity for melanoma treatment.

Abstract
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) induces cancer cell-specific apoptosis and has garnered intense interest as a promising agent for cancer treatment. However, the development of TRAIL has been hampered in part because most human cancer cells are resistant to TRAIL. A few small molecules including natural compounds such as piperlongumine (PL) have been reported to sensitize cancer cells to TRAIL. We prepared a novel type of nanomaterial, micelle-in-liposomes (MILs) for solubilization and delivery of PL. PL-loaded MILs were used to sensitize cancer cells to TRAIL. As visualized by cryo-TEM, micelles were successfully loaded inside the aqueous core of liposomes. The MILs increased the water solubility of PL by ~20 fold. A sustained PL release from MILs in physiologically relevant buffer over 7 days was achieved, indicating that the liposomes prevented premature drug release from the micelles in the MILs. Also demonstrated is a potent synergistic apoptotic effect in cancer cells by PL MILs in conjunction with liposomal TRAIL. MILs provide a new formulation and delivery vehicle for hydrophobic anticancer agents, which can be used alone or in combination with TRAIL to promote cancer cell death.

Abstract
TRAIL is considered a promising target for cancer therapy because it mediates activation of the extrinsic apoptosis pathway in a tumor-specific manner by binding to and trimerizing its functional receptors, DR4 or DR5. Although recombinant human TRAIL has shown high potency and specificity for killing cancer cells in preclinical studies, it has failed in multiple clinical trials for several reasons, including a very short half-life mainly caused by instability of the monomeric form of TRAIL and rapid renal clearance of the off-targeted TRAIL. To overcome such obstacles, we developed a TRAIL-active trimer nanocage (TRAIL-ATNC) that presents the TRAIL ligand in its trimer-like conformation by connecting it to a triple helix sequence that links to the threefold axis of the ferritin nanocage. We also ligated the tumor-targeting peptide, IL4rP, to TRAIL-ATNC to enhance tumor targeting. The developed TRAIL-ATNCIL4rP showed enhanced agonistic activity compared with monomeric TRAIL. The in vivo serum half-life of TRAIL-ATNCIL4rP was ~ 16-times longer than that of native TRAIL. As a consequence of these properties, TRAIL-ATNCIL4rP exhibited efficacy as an anti-tumor agent in vivo against xenograft breast cancer as well as orthotopic pancreatic cancer models, highlighting the promise of this system for development as novel therapeutics against cancer.

Abstract
BACKGROUND Recent studies have shown that chemotherapy destabilizes the blood vasculature and increases circulating tumor cell (CTC) influx into the circulation of metastatic cancer patients (Met-pa). CTCs are a precursor of cancer metastasis, in which they can migrate as single CTCs or as CTC clusters with stromal cells such as cancer-associated fibroblasts (CAFs) as cell aggregates. METHODS Blood samples were collected from 52 Met-pa, and the number of CTC and CAF was determined along with the temporal fluctuation of these through the chemotherapy treatment. RESULTS In this study, CTC level was found to increase two-fold from the initial level after 1 cycle of chemotherapy and returned to baseline after 2 cycles of chemotherapy. Importantly, we determined for the first time that circulating CAF levels correlate with worse prognosis and a lower probability of survival in Met-pa. Based on the CTC release induced by chemotherapy, we evaluated the efficacy of our previously developed cancer immunotherapy to eradicate CTCs from Met-pa blood using an ex vivo approach and demonstrate this could kill over 60% of CTCs. CONCLUSION Collectively, we found that CAF levels in Met-pa serve as a predictive biomarker for cancer prognosis. Additionally, we demonstrate the efficacy of our therapy to kill primary CTCs for a range of cancer types, supporting its potential use as an anti-metastasis therapy in the clinical setting.

Abstract
Targeting TRAIL (Tumor necrosis factor (TNF)-Related Apoptosis-Inducing Ligand) receptors for cancer therapy remains challenging due to tumor cell resistance and poor preparations of TRAIL or its derivatives. Herein, to optimize its therapeutic use, TRAIL was grafted onto iron oxide nanoclusters (NCs) with the aim of increasing its pro-apoptotic potential through nanoparticle-mediated magnetic hyperthermia (MHT) or photothermia (PT). Methods: The nanovector, NC@TRAIL, was characterized in terms of size, grafting efficiency, and potential for MHT and PT. The therapeutic function was assessed on a TRAIL-resistant breast cancer cell line, MDA-MB-231, wild type (WT) or TRAIL-receptor-deficient (DKO), by combining complementary methylene blue assay and flow cytometry detection of apoptosis and necrosis. Results: Combined with MHT or PT under conditions of "moderate hyperthermia" at low concentrations, NC@TRAIL acts synergistically with the TRAIL receptor to increase the cell death rate beyond what can be explained by the mere global elevation of temperature. In contrast, all results are consistent with the idea that there are hotspots, close to the nanovector and, therefore, to the membrane receptor, which cause disruption of the cell membrane. Furthermore, nanovectors targeting other membrane receptors, unrelated to the TNF superfamily, were also found to cause tumor cell damage upon PT. Indeed, functionalization of NCs by transferrin (NC@Tf) or human serum albumin (NC@HSA) induces tumor cell killing when combined with PT, albeit less efficiently than NC@TRAIL. Conclusions: Given that magnetic nanoparticles can easily be functionalized with molecules or proteins recognizing membrane receptors, these results should pave the way to original remote-controlled antitumoral targeted thermal therapies.

Abstract
Cancer is one of the leading causes of morbidity and mortality worldwide, with 1,688,780 new cancer cases and 600,920 cancer deaths projected to occur in 2017 in the U.S. alone. Conventional cancer treatments including surgical, chemo-, and radiation therapies can be effective, but are often limited by tumor invasion, off-target toxicities, and acquired resistance. To improve clinical outcomes and decrease toxic side effects, more targeted, tumor-specific therapies are being developed. Delivering anticancer payloads using tumor-tropic cells can greatly increase therapeutic distribution to tumor sites, while sparing non-tumor tissues therefore minimizing toxic side effects. Neural stem cells (NSCs) are tumor-tropic cells that can pass through normal organs quickly, localize to invasive and metastatic tumor foci throughout the body, and cross the blood-brain barrier to reach tumors in the brain. This review focuses on the potential use of NSCs as vehicles to deliver various anticancer payloads selectively to tumor sites. The use of NSCs in cancer treatment has been studied most extensively in the brain, but the findings are applicable to other metastatic solid tumors, which will be described in this review. Strategies include NSC-mediated enzyme/prodrug gene therapy, oncolytic virotherapy, and delivery of antibodies, nanoparticles, and extracellular vesicles containing oligonucleotides. Preclinical discovery and translational studies, as well as early clinical trials, will be discussed. Stem Cells Translational Medicine 2018;7:740-747.

Abstract
Escherichia coli is an essential host for large-scale expression of heterologous polypeptides. However, further applications are limited by the formation of potential protein aggregates. In this work, we developed a novel on-column tag removal and purification system based on Fh8 hydrophobic interaction chromatography purification and ΔI-CM self-cleavage to obtain soluble tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). We evaluated several methods to improve TRAIL solubility and finally demonstrated that the Fh8 tag was a powerful solubility enhancer. Finally, we replaced the tobacco etch virus (TEV) protease site with a ΔI-CM self-cleavage intein to simplify the purification process. The released soluble TRAIL purity and yield reached 98.4% and 82.1 mg/L in shake flasks, respectively. Thus, the Fh8-ΔI-CM system enhanced target protein solubility by Fh8, enabled on-column tag removal and purification based on Fh8 calcium-binding properties and ΔI-CM self-cleavage properties, and promoted the release of highly active protein with high yield and purity. Overall, our findings suggest that this Fh8-ΔI-CM system could be used as a novel solubility-inducing and purification fusion tag for protein production in E. coli.

Abstract
Tumor necrosis-factor related apoptosis-inducing ligand, also known as TRAIL or APO2L (Apo-2 ligand), is a cytokine of the TNF superfamily acknowledged for its ability to trigger selective apoptosis in tumor cells while being relatively safe towards normal cells. Its binding to its cognate agonist receptors, namely death receptor 4 (DR4) and/or DR5, can induce the formation of a membrane-bound macromolecular complex, coined DISC (death-signaling inducing complex), necessary and sufficient to engage the apoptotic machinery. At the very proximal level, TRAIL DISC formation and activation of apoptosis is regulated both by antagonist receptors and by glycosylation. Remarkably, though, despite the fact that all membrane-bound TRAIL receptors harbor putative glycosylation sites, only pro-apoptotic signaling through DR4 and DR5 has, so far, been found to be regulated by N- and O-glycosylation, respectively. Because putative N-glycosylation sequons and O-glycosylation sites are also found and conserved in all these receptors throughout all animal species (in which these receptors have been identified), glycosylation is likely to play a more prominent role than anticipated in regulating receptor/receptor interactions or trafficking, ultimately defining cell fate through TRAIL stimulation. This review aims to present and discuss these emerging concepts, the comprehension of which is likely to lead to innovative anticancer therapies.

Abstract
The immune cytokine tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has received significant attention as a cancer therapeutic due to its ability to selectively trigger cancer cell apoptosis without causing toxicity in vivo. While TRAIL has demonstrated significant promise in preclinical studies in mice as a cancer therapeutic, challenges including poor circulation half-life, inefficient delivery to target sites, and TRAIL resistance have hindered clinical translation. Recent advances in drug delivery, materials science, and nanotechnology are now being exploited to develop next-generation nanoparticle platforms to overcome barriers to TRAIL therapeutic delivery. Here, we review the design and implementation of nanoparticles to enhance TRAIL-based cancer therapy. The platforms we discuss are diverse in their approaches to the delivery problem and provide valuable insight into guiding the design of future nanoparticle-based TRAIL cancer therapeutics to potentially enable future translation into the clinic.

Abstract
Oligopeptide hydrogels for localized protein delivery have considerable potential to reduce systemic side effects but maximize therapeutic efficacy. Although enzyme catalysis to induce formation of oligopeptide hydrogels has the merits of unique regio- and enantioselectivity and mild reaction conditions, it may cause the impairment of function and activity of the encapsulated proteins by proteolytic degradation during gelation. Here we report a novel enzyme-catalysis strategy for self-assembly of oligopeptide hydrogels using an engineered protease nanocapsule with tunable substrate selectivity. The protease-encapsulated nanocapsule shielded the degradation activity of protease on the laden proteins due to the steric hindrance by the polymeric shell weaved around the protease, whereas the small-molecular precursors were easier to penetrate across the polymeric network and access the catalytic pocket of the protease to convert to the gelators for self-assembling hydrogel. The resulting oligopeptide hydrogels supported a favorable loading capacity without inactivation of both an antiangiogenic protein, hirudin and an apoptosis-inducing cytokine, TRAIL as model proteins. The hirudin and TRAIL coloaded oligopeptide hydrogel for combination cancer treatment showed enhanced synergistic antitumor effects both in vitro and in vivo.

Abstract
TNF-related apoptosis-inducing ligand (TRAIL/Apo2L) has long been considered a tantalizing target for cancer therapy because it mediates activation of the extrinsic apoptosis pathway in a tumor-specific manner by binding to and trimerizing its functional receptors DR4 or DR5. Despite initial promise, both recombinant human TRAIL (native TRAIL) and dimeric DR4/DR5 agonist monoclonal antibodies (mAbs) failed in multiple human clinical trials. Here we show that in-frame fusion of human C-propeptide of α1(I) collagen (Trimer-Tag) to the C-terminus of mature human TRAIL leads to a disulfide bond-linked homotrimer which can be expressed at high levels as a secreted protein from CHO cells. The resulting TRAIL-Trimer not only retains similar bioactivity and receptor binding kinetics as native TRAIL in vitro which are 4-5 orders of magnitude superior to that of dimeric TRAIL-Fc, but also manifests more favorable pharmacokinetic and antitumor pharmacodynamic profiles in vivo than that of native TRAIL. Taken together, this work provides direct evidence for the in vivo antitumor efficacy of TRAIL being proportional to systemic drug exposure and suggests that the previous clinical failures may have been due to rapid systemic clearance of native TRAIL and poor apoptosis-inducing potency of dimeric agonist mAbs despite their long serum half-lives.

Abstract
To remedy the drug resistance of natural tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and enhance its antitumor effects, we prepared a type of TRAIL mutant membrane penetrating peptide alike (TMPPA)‑TRAIL mutant R6 (MuR6-TR) by mutating the N‑terminal of the soluble TRAIL gene sequence. The expressed MuR6‑TR protein was purified to treat pancreatic carcinoma cell lines BxPC‑3 and PANC‑1. The inhibitory effects on the proliferation of BxPC‑3 and PANC‑1 cells was assessed with CCK‑8 assay and compared with natural TRAIL. The antitumor effect of MuR6‑TR was assessed on implant tumors derived from PANC‑1 cells in nude mice and compared with gemcitabine. Finally, the soluble MuR6‑TR gene was successfully mutated with 4 amino acids in the N‑terminal of TRAIL and had a molecular size of 513 bp. The mutant MuR6‑TR was connected to pET32a and verified by enzymatic digestion and sequencing. The recombinant MuR6‑TR was transformed and expressed in Escherichia coli. The CCK‑8 assay results indicated that MuR6‑TR inhibited the growth of BxPC‑3 and PANC‑1 cells in a dose‑dependent manner, with IC50 values of 4.63 and 7.84 ng/ml, respectively, which were much lower than that of natural TRAIL. MuR6‑TR demonstrated a higher inhibitory effect on tumor growth (24.2%) than natural TRAIL (14.4%) and an effect similar to that of gemcitabine at an early period. Thus, the mutant MuR6‑TR exhibited a stronger antitumor effect than that of natural TRAIL both in vivo and in vitro and may have potential therapeutic value for pancreatic carcinoma, which requires further validation.

Abstract
PURPOSE Non-small cell lung cancer (NSCLC) is one the types of cancer with higher prevalence and mortality. Apo2-Ligand/TRAIL is a TNF family member able to induce apoptosis in tumor cells but not in normal cells. It has been tested in clinical trials against different types of human cancer including NSCLC. However, results of clinical trials have shown a limited efficacy of TRAIL-based therapies. Recently we have demonstrated that artificial lipid nanoparticles coated with bioactive Apo2L/TRAIL (LUV-TRAIL) greatly improved TRAIL cytotoxic ability being capable of killing chemoresistant hematological cancer cells. In the present work we have extended the study to NSCLC. METHODS/PATIENTS LUV-TRAIL-induced cytotoxicity was assessed on different NSCLC cell lines with different sensitivity to soluble TRAIL and on primary human tumor cells from three patients suffering from NSCLC cancer. We also tested LUV-TRAIL-cytotoxic ability in combination with several anti-tumor agents. RESULTS LUV-TRAIL exhibited a greater cytotoxic effect compared to soluble TRAIL both in A549 cells and primary human NSCLC cells. LUV-TRAIL-induced cell death was dependent on caspase-8 and caspase-3 activation. Moreover, combination of LUV-TRAIL with other anti-tumor agents such as flavopiridol, and SNS-032 clearly enhanced LUV-TRAIL-induced cytotoxicity against NSCLC cancer cells. CONCLUSION The novel formulation of TRAIL based on displaying it on the surface of lipid nanoparticles greatly increases its anti-tumor activity and has clinical potential in cancer treatment.

Abstract
The structure of death receptor 4 (DR4) in complex with TNF-related apoptosis-inducing ligand (TRAIL) has been determined at 3 Å resolution and compared with those of previously determined DR5-TRAIL complexes. Consistent with the high sequence similarity between DR4 and DR5, the overall arrangement of the DR4-TRAIL complex does not differ substantially from that of the DR5-TRAIL complex. However, subtle differences are apparent. In addition, solution interaction studies were carried out that show differences in the thermodynamics of binding DR4 or DR5 with TRAIL.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL or Apo2L) is a member of the tumor necrosis factor (TNF) superfamily. This type II transmembrane protein is able to bound specifically to cancer cell receptors (i.e., TRAIL-R1 (or DR4) and TRAIL-R2 (or DR5)) and to induce apoptosis without being toxic for healthy cells. Because membrane-bound TRAIL induces stronger receptor aggregation and apoptosis than soluble TRAIL, we proposed here to vectorize TRAIL using single-walled carbon nanotubes (SWCNTs) to mimic membrane TRAIL. Owing to their exceptional and revolutional properties, carbon nanotubes, especially SWCNTs, are used in a wide range of physical or, now, medical applications. Indeed due to their high mechanical resistance, their high flexibility and their hydrophobicity, SWCNTs are known to rapidly diffuse in an aqueous medium such as blood, opening the way of development of new drug nanovectors (or nanocarriers). Our TRAIL-based SWCNTs nanovectors proved to be more efficient than TRAIL alone death receptors in triggering cancer cell killing. These NPTs increased TRAIL pro-apoptotic potential by nearly 20-fold in different Human tumor cell lines including colorectal, nonsmall cell lung cancer, or hepatocarcinomas. We provide thus a proof-of-concept that TRAIL nanovector derivatives based on SWCNT may be useful to future nanomedicine therapies.

Abstract
Death receptor agonist therapies have exhibited limited clinical benefit to date. Investigations into why Apo2L/TRAIL and AMG 655 preclinical data were not predictive of clinical response revealed that coadministration of Apo2L/TRAIL with AMG 655 leads to increased antitumor activity in vitro and in vivo. The combination of Apo2L/TRAIL and AMG 655 results in enhanced signaling and can sensitize Apo2L/TRAIL-resistant cells. Structure determination of the Apo2L/TRAIL-DR5-AMG 655 ternary complex illustrates how higher order clustering of DR5 is achieved when both agents are combined. Enhanced agonism generated by combining Apo2L/TRAIL and AMG 655 provides insight into the limited efficacy observed in previous clinical trials and suggests testable hypotheses to reconsider death receptor agonism as a therapeutic strategy.

Abstract
Approximately 90% of cancer related deaths are due to metastasis. Cells from the primary tumor can metastasize through either the vascular or lymphatic circulation. Cancer cells in circulation are called circulating tumor cells (CTCs) and it has been shown that bone marrow is a niche for homing of blood borne CTCs from several epithelial tumors. Cancer cells found in bone marrow are termed disseminated tumor cells (DTCs). Likewise, CTCs in the lymphatic circulation are more often seeded in the sentinel lymph nodes (SLN) that drain the tumor. Micrometastases (<2 mm) occur after the arrest and implantation of DTCs in lymph nodes over time. This paper presents a cell culture platform termed microbubbles formed in polydimethylsiloxane (PDMS) from a microfabricated silicon wafer for mimicking lymph node micrometastases. We cultured lymph node seeking cancer cells in microbubbles to evaluate the efficacy of natural killer (NK) mediated therapy for targeting lymph node micrometastasis. The microbubble platform consists of an array of microcavities that provides a unique microenvironment for mimicking the deep cortical unit of the lymph nodes. We show that cancer cells cultured in microbubbles with therapeutic NK cells undergo apoptosis after 24 h in culture. Since lymph node metastases are prevalent across several types of cancer, this platform may be useful for developing improved cancer therapies for targeting lymph node micrometastases.

Abstract
Background New strategies for the treatment of hepatocellular carcinoma (HCC) are needed, given that currently available chemotherapeutics are inefficient. Since tumor growth reflects the net balance between pro-proliferative and death signaling, agents shifting the equilibrium toward the latter are of considerable interest. The TWEAK:Fn14 signaling axis promotes tumor cell proliferation and tumor angiogenesis, while TRAIL:TRAIL-receptor (TRAIL-R) interactions selectively induce apoptosis in malignant cells. Fn14•TRAIL, a fusion protein bridging these two pathways, has the potential to inhibit tumor growth, by interfering with TWEAK:Fn14 signaling, while at the same time enforcing TRAIL:TRAIL-R-mediated apoptosis. Consequently, Fn14•TRAIL's capacity to inhibit HCC growth was tested. Results Fn14•TRAIL induced robust apoptosis of multiple HCC cell lines, while sparing non-malignant hepatocyte cell lines. Differential susceptibility to this agent did not correlate with expression levels of TRAIL, TRAIL-R, TWEAK and Fn14 by these lines. Fn14•TRAIL was more potent than soluble TRAIL, soluble Fn14, or a combination of the two. The requirement of both of Fn14•TRAIL's molecular domains for function was established using blocking antibodies directed against each of them. Subcutaneous injection of Fn14•TRAIL abrogated HCC growth in a xenograft model, and was well tolerated by the mice. Conclusions In this study, Fn14•TRAIL, a multifunctional fusion protein originally designed to treat autoimmunity, was shown to inhibit the growth of HCC, both invitro and invivo. The demonstration of this fusion protein’s potent anti-tumor activity suggests that simultaneous targeting of two signaling axes by a single fusion can serve as a basis for highly effective anti-cancer therapies.

Abstract
Monomethyl auristatin E (MMAE) is conjugated with TNF-related apoptosis-inducing ligand (TRAIL) via a linker that is stable in extracellular fluid, while it is cleaved by cathepsin once the conjugate has entered a tumor cell, thus activating the antimitotic mechanism of MMAE. The TRAIL-MMAE conjugate is a conceptually viable therapeutic strategy with improved in vitro antitumor activity, cell circle arrest and specific accumulation in tumor to treat TRAIL-resistant tumors.

Abstract
CONTEXT Histone deacetylase inhibitors (HDACis) are anticancer agents that inhibit tumor cell growth and/or survival. However, their mechanism of action remains largely undefined. Recently, we have demonstrated that HDACis induce apoptosis in a model of rat thyroid cells transformed by the v-ras-Ki oncogene (FRTL-5 v-ras-Ki). The stabilization of TNF-related apoptosis-inducing ligand (TRAIL) protein, due to its reduced ubiquitination and proteasome degradation, accounts for the apoptotic effect induced specifically by suberoylanilide hydroxamic acid (SAHA, Vorinostat) in the v-ras-Ki thyroid transformed cells. OBJECTIVE The aim of this work was to investigate whether SAHA may induce its cytotoxic effects also deregulating microRNA (miRNA) expression levels. DESIGN We analyzed the miRNA expression profile of the thyroid transformed cells, FRTL-5 v-ras-Ki, upon SAHA treatment. RESULTS Here we report that SAHA induces the down-regulation of 18 and the up-regulation of 11 miRNAs with a fold change higher than 2 in the transformed cells. Then, we focus on the miR-146b and miR-200b, respectively up-regulated and down-regulated by SAHA. We show that both these miRNAs target genes coding for proteins with a critical role in proteasome composition and ubiquitin degradation. CONCLUSION These results suggest a role of miRNA deregulation in TRAIL protein stabilization responsible for SAHA-induced apoptotic effect in thyroid transformed cells.

Abstract
We have developed a straightforward strategy to multimerize an apoptogenic peptide that mimics the natural tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) by using adamantane-based dendrons as multivalent scaffolds. The selective binding affinity of the ligands to TRAIL receptor 2 (TR2) was studied by surface plasmon resonance, thus demonstrating that the trimeric and hexameric forms of the peptide exert an increased affinity of about 1500- and 20,000-fold, respectively, relative to the monomer. Moreover, only the trimeric and hexameric ligands were able to induce cell death in TR2 expressing cells (BJAB), thus confirming that a multivalent form of the peptide is necessary to trigger a substantial TR2-dependent apoptotic response in vitro. These results provide interesting insight into the multivalency effect on biological ligand/receptor interactions for future therapeutic applications.

Abstract
AIM To construct the expression vector pET-28α-Trail(114-281); and find the optimal conditions for target gene expression, host bacteria lysis, and protein purification, and to detect the apoptosis function of the recombinant protein. METHODS The functional domain of Trail(114-281); was amplified by PCR and cloned into the expression vector pET-28α(+). After confirmed by DNA sequencing, the Trail(114-281); was expressed in E.coli BL21 under the condition of different A(600);, IPTG concentration and temperature. Host bacteria were lysed using three different ways, including ultrasonication, osmotic shock and IP lysis, and the target protein was purified using Ni-NTA affinity chromatography or cutting-gel purification. The advantages and shortcomings of these methods were compared to find the most efficient ways for expression and purification of the recombinant protein. The immunocompetence of Trail protein from cutting-gel purification was analyzed by Western blotting, A549 cell apoptosis induced by purified protein from Ni-NTA chromatography was detected by flow cytometry. RESULTS The 516 bp Trail(114-281); gene was cloned, and expressed in E.coli BL21. When A(600);=0.6, recombinant host bacteria were induced by 1.0 mmol/L IPTG at 37 DegreesCelsius for 4 h, which was the optimal condition for the expression of inclusion body, and the soluble protein was expressed stably on the condition of 25 DegreesCelsius, A(600);=1.0, IPTG1.0 mmol/L. Ultrasonication could get maximal protein compared to the other methods. The two purification ways both could purify taget protein successfully. Western blot analysis showed that the protein purified by cutting-gel has a good immunologic activity. Protein from Ni-NTA affinity chromatography caused cell apoptosis. CONCLUSION The expression vector pET-28α-Trail(114-281); can be constructed and expressed in E.coli BL21 successfully. Temperature is a more important effect factor of Trail(114-281); expression in host bacteria compared with other factors. Cutting-gel protein has immunogenicity, and Ni-NTA protein could keep its function. These results provide a basis for the further functional research and application of Trail.

Abstract
BACKGROUND Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) could induce apoptosis of HIV-1-infected monocyte-derived macrophage (MDM), but the molecular mechanisms are not well understood. METHODOLOGY/PRINCIPAL FINDINGS By using an HIV-1 Env-pseudotyped virus (HIV-1 PV)-infected MDM cell model we demonstrate that HIV-1 PV infection down-regulates the expression of TRAIL decoy receptor 1 (DcR1) and 2 (DcR2), and cellular FLICE-inhibitory protein (c-FLIP), but dose not affect the expression of death receptor 4 and 5 (DR4, DR5), and Bcl-2 family members in MDM cells. Furthermore, recombinant soluble TRAIL and an agonistic anti-DR5 antibody, AD5-10, treatment stimulates reactive oxygen species (ROS) generation and JNK phosphorylation. CONCLUSIONS/SIGNIFICANCE HIV infection facilitates TRIAL-induced cell death in MDM by down-regulating the expression of TRAIL decoy receptors and intracellular c-FLIP. Meanwhile, the agonistic anti-DR5 antibody, AD5-10, induces apoptosis synergistically with TRAIL in HIV-1-infected cells. ROS generation and JNK phosphorylation are involved in this process. These findings potentiate clinical usage of the combination of TRAIL and AD5-10 in eradication of HIV-infected macrophage and AIDS.

Abstract
In our previous study, we have shown that vector pBV22210 containing a chloramphenicol resistance and a cryptic plasmid pMB1 from Bifidobacterium longum strain could stably replicate and did not significantly affect the biological characteristics of B. longum. In this study, B. longum was transfected by electroporation with pBV22210 encoding the extracellular domain of TRAIL (B. longum-pBV22210-TRAIL) and its carbohydrate fermentation and growth curve were determined, and its location and inhibitory effect on tumor xenografts in mice were also examined. The results further proved that gene transfection did not change the main biochemical characteristics of B. longum. The results also showed that B. longum-pBV22210-TRAIL resulted in selective location in tumors and exhibited a definite antitumor effect on S180 osteosarcoma. In addition, when a low dosage of Adriamycin (5 mg kg(-1)) or B. longum-pBV22210-endostatin was combined, the antitumor effect was significantly enhanced. The successful inhibition of S180 tumor growth suggested a stable vector in B. longum for transporting anticancer genes combined with low-dose chemotherapeutic drugs or other target genes is a promising approach in cancer gene therapy.

Abstract
Unlike other TNF ligand family members, the homotrimeric tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) contains a buried zinc atom coordinated by three Cys230 residues from each subunit. The bound zinc ion is essential for maintaining the structure stability and bioactivity of TRAIL. To improve characteristics of TRAIL by modification to enhance its zinc-binding ability, we constructed a new variant of TRAIL in which the extracellular region of the ligand was N-terminally fused with a trimeric coiled-coil domain derived from human pulmonary surfactant-associated protein D (ST), and compared its characteristics with that of native TRAIL. Circular dichroism (CD) studies and metal assays showed that two versions of TRAIL folded as predicted into secondary and tertiary structures, and contained stoichiometric Zn(2+) through optimizing bacterial expression and purification. The addition of the human trimeric coiled-coil domain, however, significantly increased the antitumor activity of soluble TRAIL in vitro and in vivo. The accelerated thermal stability studies demonstrated that human serum album (HSA) promoted the aggregation and degradation of native TRAIL, but not ST, and the addition of ZnSO(4) to the solution of native TRAIL with HSA partially inhibited its aggregation, suggesting ST is more difficult to lose its bound zinc ion than native TRAIL. The issue was further confirmed by dialysis assess. This is the first example of modified TRAIL with enhanced zinc-binding ability.

Abstract
The Death Receptor 5 (DR5), a member of tumor necrosis factor receptor (TNFR) superfamily of receptors, triggers apoptosis (programmed cell death) when stimulated by its tridentate ligand TRAIL. Until recently it was generally assumed that the activation of DR5 resulted from the recruitment of three independent receptor units, leading to the trimerization of intracellular domains. However, there is mounting evidence to suggest that, in the absence of ligand, such cytokine receptors primarily reside as preformed complexes. In this work, molecular dynamics simulations of the TRAIL-DR5 complex, the unbound receptor trimer and individual receptor monomers are compared to gain insight in the mechanism of activation. The results suggest that, in the absence of TRAIL, DR5 has a strong propensity to self-associate and that this is primarily mediated through interactions of the membrane proximal domains. The association of the free receptors leads to a loss of the threefold symmetry found within the receptor-ligand complex. The simulations suggest that the primary role of TRAIL is to induce threefold-symmetry within the DR5 complex and to constrain the receptor to a specific conformation. The implications of this in terms of the mechanism by which the receptor switches from an inactive to an active state are discussed.

Abstract
The extrinsic apoptosis pathway is activated when certain members of the tumor necrosis factor (TNF) receptor superfamily (TNFRSF) are oligomerized by their cognate ligands that are members of the TNF superfamily (TNFSF). The apoptosis-inducing capacity of a member of the TNFRSF relies on the presence of a death domain (DD) in the intracellular portion of the receptor protein. Such receptors are also referred to as death receptors. Binding of a TNFSF ligand to a TNFRSF receptor that is expressed on the surface of a cell results in the formation of a receptor proximal protein complex. This protein complex is the platform for further signaling events within the cell. In case of death receptors like TNF-related apoptosis-inducing ligand receptor 1 (TRAIL-R1/DR4), TRAIL-R2 (KILLER/APO-2/DR5/TRICK), CD95 (Fas, APO-1), or TNF receptor 1 (TNF-R1), this complex is termed death-inducing signaling complex (DISC). The compositions of the various DISCs have been intensively studied in the last 12 years. For the CD95 and the TRAIL-R1/R2 DISCs, it is now clear that the adaptor protein Fas-associated DD protein (FADD) forms part of these complexes and is necessary for recruitment of the proapoptotic signaling molecules caspase-8 and caspase-10. Recruitment of these proteases allows for their activation at the DISC and subsequent induction of apoptosis. The caspase-8 homologous cellular FLICE-like inhibitory protein (cFLIP) can also be recruited to the DISC. cFLIP acts as an anti-apoptotic regulator by interfering with activation of caspases 8 and 10 at the DISC. Interestingly, treatment of TRAIL-resistant tumor cells with conventional chemotherapeutic drugs or with proteasome inhibitors renders these cells sensitive for TRAIL-induced apoptosis. By applying the methodology of the biochemical analysis of the TRAIL DISC described here, we were able to show that this sensitization is mainly due to changes in the biochemical composition of the DISC as the apoptosis-initiating protein complex of the extrinsic pathway.

Abstract
We recently demonstrated the activation of phosphatidylinositol 3-kinase (PI3-K/Akt) survival pathway in Jurkat T leukemia cells known for their sensitivity to the tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)/Apo2L cytotoxic action. The present investigation was done to elucidate the role of cAMP-response element-binding (CREB) protein in this system. Jurkat T cells were treated with 100-1,000 ng/ml TRAIL for time intervals up to 24 h in the presence or absence of selective pharmacologic inhibitors of PI3-K/Akt (LY294002) or p38 MAPK (SB253580) pathways. Upon TRAIL treatment, a dose-dependent increase in the percentage of apoptotic cells as well as in caspase-3 activity was observed. A further enhancement of apoptotic cell death was obtained with the use of CREB1 siRNA technology, as demonstrated by flow cytometry. Western blot analysis showed a high constitutive level of CREB phosphorylation at Ser(133) in Jurkat T cells under normal serum culture conditions. Under low serum culture conditions, an early (within 1 h) and transient increase in CREB phosphorylation was detected in response to both TRAIL doses and reduced upon pre-treatment with LY294002 or SB253580, demonstrating the PI3-K/Akt- and p38 MAPK-dependency of this effect. The parallel analysis in immune fluorescence demonstrated the nuclear translocation of the phosphorylated form upon treatment with 100 ng/ml TRAIL, whereas the immune labeling was mainly detectable in the cytoplasm compartment upon the higher more cytotoxic dose. These results let us hypothesize that CREB activation can be an important player in the complex cross-talk among pro- and anti-apoptotic pathways in this peculiar cell model.

Abstract
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is one of the TNF superfamily members, participating in many biological processes including cell proliferation and apoptotic death. In this study, a TRAIL gene was cloned from a perciform fish, the mandarin fish Siniperca chuatsi, a major cultured fish in China's aquaculture, and is named as SCTRAIL for S. chuatsi TRAIL. The full-length cDNA of SCTRAIL is 1359bp, encoding a 283-amino-acid protein. This deduced protein contains the Cys(231), a 23-mer fragment of transmembrane region, a glycosylation site and a TNF family signature, all of which are conserved among TRAIL members. SCTRAIL gene consists of six exons, with five intervening introns, spaced over approximately 9kb of genomic sequence. Southern blotting demonstrated that the SCTRAIL gene is present as a single copy in mandarin fish genome. A 620bp promoter region obtained by genome walking contains a number of putative transcription factor binding sites, such as Oct-1, Sp-1, NF-1, RAP-1, C/EBPalp, NF-kappaB and AP-1. The SCTRAIL is constitutively expressed in all the analyzed tissues, as revealed by RT-PCR, which is confirmed by Western blotting analysis using polyclonal antibody against bacteria-derived recombinant SCTRAIL protein. As an apoptosis-inducing ligand, the overexpression of SCTRAIL but not the mutant SCTRAIL-C203S in HeLa cells induced changes characteristic of apoptosis, including chromatin condensation, nucleus fragmentation, DNA ladder, and increase of sub-G0/G1 cells in FACS analysis.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is known to induce apoptosis to various tumor cells but not in normal cells. We have screened cell death-inducing peptides from the extracellular domain sequence of TRAIL, using a peptide array. Peptides of higher activity were found through amino acid substitution, and the CNSCWSKD peptide induced >90% cell death in treated Jurkat cells. Features of apoptosis, such as DNA fragmentation, activation of caspase, phosphatidylserine externalization, chromatin condensation, and competition with TRAIL for binding to the death receptor (DR) 4 or DR5 were observed, suggesting that this peptide is a TRAIL mimic. Caspase-3 activation was observed in various tumor cells treated with this peptide as well as with TRAIL, while no activation was observed in human normal fibroblasts. The CNSCWSKD peptide is a potential candidate for use in cancer therapy.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), existing as homotrimer in solution, contains a unique zinc-binding site coordinated by three Cys230 residues at the tip of trimeric interface. TRAIL mutant with replacements of Cys230 with Ala (TRAIL(C230A)) negligibly formed trimeric structure and showed no apoptotic activity. Here, to elucidate the relationship between the trimeric stability and the apoptotic activity of TRAIL(C230A), we rationally designed mutations to induce homotrimerization of TRAIL(C230A) by substituting for the three residues involved in hydrogen bonding (Tyr183 and Tyr243) and putative repulsive electrostatic (Arg227) interactions at the buried trimeric interface into hydrophobic residues, like Y183F, Y243F, and R227I. The TRAIL(C230A)-derived mutants exhibited enhanced homotrimerization, but only the mutants containing R227I exhibited significant apoptosis-inducing activity in cancer cells. These results, together with the induction of rigid local structure around the zinc-binding region by R227I in TRAIL(C230A), suggest that ordered, rigid structure around the zinc-binding region is critical for the homotrimerization and apoptotic activity of TRAIL.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is capable of inducing apoptosis in non-small cell lung carcinoma (NSCLC). However, many of the human NSCLC cell lines are resistant to TRAIL, and TRAIL treatment of the resistant cells leads to the activation of nuclear factor-kappaB (NF-kappaB) and extracellular signal-regulated kinase 1/2 (ERK1/2). TRAIL can induce apoptosis in TRAIL-sensitive NSCLC cells through the induction of death-inducing signaling complex (DISC) assembly in lipid rafts of plasma membrane. In the DISC, caspase-8 is cleaved and initiates TRAIL-induced apoptosis. In contrast, TRAIL-DISC assembly in the nonraft phase of the plasma membrane leads to the inhibition of caspase-8 cleavage and NF-kappaB and ERK1/2 activation in TRAIL-resistant NSCLC cells. Receptor-interacting protein (RIP) and cellular Fas-associated death domain-like interleukin-1beta-converting enzyme-inhibitory protein (c-FLIP) mediates the DISC assembly in nonrafts and selective knockdown of either RIP or c-FLIP with interfering RNA redistributes the DISC from nonrafts to lipid rafts, thereby switching the DISC signals from NF-kappaB and ERK1/2 activation to caspase-8-initiated apoptosis. Chemotherapeutic agents inhibit c-FLIP expression, thereby enhancing the DISC assembly in lipid rafts for caspase-8-initiated apoptosis. These studies indicate that RIP and c-FLIP-mediated assembly of the DISC in nonrafts is a critical upstream event in TRAIL resistance and thus targeting of either RIP or c-FLIP may lead to the development of novel therapeutic strategies that can overcome TRAIL resistance in human NSCLC.

Abstract
Variants of human TRAIL (hTRAIL) and human CD95L (hCD95L), encompassing the TNF homology domain (THD), interact with the corresponding receptors and stimulate CD95 and TRAILR2 signaling after cross-linking. The murine counterparts (mTRAIL, mCD95L) showed no or only low receptor binding and were inactive/poorly active after cross-linking. The stalk region preceding the THD of mCD95L conferred secondary aggregation and restored CD95 activation in the absence of cross-linking. A corresponding variant of mTRAIL, however, was still not able to activate TRAIL death receptors, but gained good activity after cross-linking. Notably, disulfide-bonded fusion proteins of the THD of mTRAIL and mCD95L with a subdomain of the tenascin-C (TNC) oligomerization domain, which still assembled into trimers, efficiently interacted with their cognate cellular receptors and robustly stimulated CD95 and TRAILR2 signaling after secondary cross-linking. Introduction of the TNC domain also further enhanced the activity of THD encompassing variants of hTRAIL and hCD95L. Thus, spatial fixation of the N-terminus of the THD appears necessary in some TNF ligands to ensure proper receptor binding. This points to yet unanticipated functions of the stalk and/or transmembrane region of TNF ligands for the functionality of these molecules and offers a broadly applicable option to generate recombinant soluble ligands of the TNF family with superior activity.

Abstract
Osteoprotegerin (OPG) binds the ligand for receptor activator of nuclear factor kappaB (RANKL) to prevent association with its receptor RANK and inhibit osteoclast-mediated bone resorption. OPG has been reported, recently, to inhibit tumor necrosis factor-related apoptosis-induced ligand (TRAIL)-induced tumor cell apoptosis. This raises the possibility that OPG may play a unique role in regulating these two signaling pathways. However, there are little data on the interactions between OPG, RANKL, and TRAIL, and the relative affinity of OPG for these two ligands is unknown. In the present study we examined the ability of OPG to bind native human TRAIL and RANKL under physiological conditions. Native TRAIL was expressed in Escherichia coli, purified to homogeneity, and shown to induce human myeloma cell apoptosis. OPG inhibited native TRAIL from binding the TRAILR1 at 37 degrees C in vitro. Similarly, OPG prevented RANKL from binding to RANK. TRAIL also prevented OPG-mediated inhibition of RANKL from binding RANK. The affinity of OPG for native TRAIL and RANKL at 37 degrees C was determined by plasmon surface resonance analysis. OPG had a binding affinity for TRAIL of 45 nM, whereas the affinity of OPG for RANKL was 23 nM. These data suggest that OPG can bind both RANKL and TRAIL and that the affinity of OPG for these two ligands is of a similar order of magnitude. Furthermore, OPG prevented TRAIL-mediated reductions in cell viability, whereas TRAIL inhibited OPG-mediated inhibition of osteoclastogenesis in vitro. This highlights the pivotal role of OPG in regulating the biology of both RANKL and TRAIL.

Abstract
The TNF superfamily (TNFSF) of proteins are cytokines involved in diverse immunological and developmental pathways. Little is known about their evolution or expression in lower vertebrate species. Bioinformatic searches of Zebrafish, Tetraodon, and Fugu genome and other teleost expressed sequence tag databases identified 44 novel gene sequences containing a TNF homology domain. This work reveals the following: 1) teleosts possess orthologs of BAFF, APRIL, EDA, TWEAK, 4-1BBL, Fas ligand, LIGHT, CD40L, RANKL, and possibly TL1A; 2) the BAFF-APRIL subfamily is enriched by a third member, BALM, unique to fish; 3) orthologs of lymphotoxins alpha and beta were not clearly identified in teleosts and are substituted by a related ligand, TNF-New; 4) as many as four TRAIL-like genes are present in teleosts, as compared with only one in mammals; and 5) T cell activation ligands OX40L, CD27L, CD30L, and GITRL were not identified in any fish species. Finally, we characterize mRNA expression of TNFSF members CD40L, LIGHT, BALM, APRIL, Fas ligand, RANKL, TRAIL-like, and TNF-New in rainbow trout, Oncorhynchus mykiss, immune and nonimmune tissues. In conclusion, we identified a total of 14 distinct TNFSF members in fishes, indicating expansion of this superfamily before the divergence of bony fish and tetrapods, approximately 360-450 million years ago. Based on these findings, we extend a model of TNFSF evolution and the co-emergence of the vertebrate adaptive immune system.

Abstract
Tumor necrosis factor (TNF)-related, apoptosis-inducing ligand (Apo2L/TRAIL) has a unique homotrimeric structure, and its conformational stability is essential for its apoptotic activity. The conformational stability of a modified version of TRAIL(114-281) with two additional domains of histidine tag and isoleucine zipper [His-ILZ-TRAIL(114-281)] was evaluated in various pH environments according to three different biological or physicochemical considerations: cytotoxicity, antibody-binding affinity, and tertiary structure. The biological properties of His-ILZ-TRAIL(114-281) were the most stably maintained at pH 6.0. The physicochemical analyses (circular dichroism and fluorescence spectroscopy) demonstrate that its bioactivity loss by pH challenge was originated from its structural collapse as a homotrimer.

Abstract
TNF-related apoptosis-inducing ligand (TRAIL/Apo2L) was produced mainly as inclusion bodies (IBs) by recombinant Escherichia coli with a temperature-inducible expression system. The yield of TRAIL type 2 IBs at higher preinduction specific growth rate (mu = 0.15 h-1) was higher than that of TRAIL type 1 IBs at lower preinduction specific growth rate (mu = 0.05 h-1). With the same optimized refolding protocols, two types of IBs exhibited different refolding features. Refolded type 1 IBs had higher recovery of more than 80% compared with type 2 IBs (57-63%). By the measurements of fluorescence and CD spectroscopy, type 1 TRAIL IBs dissolved by urea appeared to be a closer secondary structure to the native TRAIL than type 2. Furthermore, with trypsin treatment, the striking decrease in stability of type 1 IBs against protease digestion cannot be attributed to their small size particles observed by scanning electron microscope and probably depend on different protein structure properties between the two IBs. Different properties of inclusion bodies were mainly influenced by different physiological states of the cells just prior to the induction.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a new member of the TNF superfamily. Here, a recombinant form of the extracellular domain of the TRAIL (sTRAIL) was expressed in Escherichia coli BL21(DE3) under the control of a T7 promoter. The resulting insoluble bodies were separated from cellular debris by centrifugation and solubilized with 8 M urea. A rapid and simple on-column refolding procedure was developed. It was applied and then the refolded sTRAIL was purified by anion-exchange chromatography. The purified final product was >98% pure by SDS-PAGE stained with Coomassie brilliant blue R-250. Mass spectroscopic analysis indicated the protein to be 19.2 kDa, which equalled the theoretically expected mass. N-terminal sequencing of refolding sTRAIL showed the sequence which corresponded to the designed protein. The renatured protein displayed its immunoreactivity with the antibodies to TRAIL protein by Western blotting. The purified sTRAIL had a strong cytotoxic activity against human cervical cancer HeLa cells with ED50 about 1.5 mg/L. Circular dichroism and fluorescence spectrum analysis showed that the refolded sTRAIL had a structure similar to that of native protein with beta-sheet secondary structure. This efficient procedure of sTRAIL renaturation may be useful for the mass production of this therapeutically important protein.

Abstract
The extracellular domain of the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) may function as a soluble cytokine to selectively kill various cancer cells without toxicity to most normal cells. We used a high-biosafety plasmid pVAX1 as a vector and constructed a recombinant plasmid expressing the extracellular domain (95-281 aa) of human TRAIL fused with signal peptides of human IgGgamma, designated as pVAX-sT. Transduction of human BEL7402 liver cancer cells with pVAX-sT led to high levels of sTRAIL protein in the cell culture media and induced apoptosis. The therapeutic potential of pVAX-sT was then evaluated in the BEL7402 transplanted naked mouse model. Subsequent intratumoral administration of naked pVAX-sT resulted in the expression of soluble TRAIL in the sera and the tumor site, as well as effective suppression of tumor growth, with no toxicity to liver. In conclusion, the successful inhibition of liver cancer growth and the absence of detectable toxicity suggest that pVAX-sT could be useful in the gene therapy of liver cancer.

Abstract
Defects in programmed cell death or apoptosis are major hallmarks of cancer contributing to tumorigenesis, tumor progression, and therapy resistance. In the past decade, many of the pathways leading to apoptosis, as well as the molecular mechanisms blocking the death of tumor cells, have been elucidated. This detailed knowledge of the core apoptosis machinery is now being exploited for translation into novel cancer therapies in order to restore apoptosis induction in tumor cells. Strategies include activation of proapoptotic mediators such as death receptors, tumor protein p53, and second mitochondria-derived activator of caspases (SMAC)/DIABLO as well as inhibition of endogenous apoptosis inhibitors such as IAPs (inhibitor of apoptosis proteins) and BCL-2 (B-cell chronic lymphoid leukemia/lymphoma) proteins. Several approaches employing gene therapy and antisense strategies, recombinant biologics, or classic organic and combinatorial chemistry, have advanced into clinical trials or are already approved. This review looks at recent developments in apoptosis-based cancer therapies and highlights some very promising advances in drug design.

Abstract
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis in various tumor cells and virus-infected cells, but rarely in normal cells. The killing specificity of TRAIL has brought great interests to develop a novel apoptosis-based anti-tumor agent for clinical application. TRAIL is expressed in many normal tissues and cells, such as liver, brain, kidney, heart, colon, lung, and testis. However, immunological and physiological functions of TRAIL in vivo have not been understood well. In the present paper we summarized the progress in the research on immunological functions of TRAIL.

Abstract
AIM To investigate the regulation of soluble and membrane bound TNF-related apoptosis-inducing ligand (TRAIL) in Jurkt cells by phorbol myristic acctate (PMA), and the cytotoxicity of the two forms of TRAIL. METHODS Jurkat cells were cultured in the presence of 40 ng/mL PMA for different time. The production of sTRAIL was determined by ELISA, and expression of mTRAIL was analyzed by indirect fluorescence staining and flow cytometry analysis. The cytotoxicites of sTRAIL and mTRAIL were detected by (51)Cr release assay, in which DR4/DR5-expressing Raji cells were employed as target cells. RESULTS The expression of both sTRAIL and mTRAIL in Jurkat cells were upregulated by PMA. The level of sTRAIL in supernatant from PMA-stimulated Jurkat cell culture increased and reached peak at 48 hours after PMA treatment, whereas expression peak of mTRAIL was at 60 hours. Both sTRAIL and mTRAIL exhibited cytotoxicity against Raji cells. CONCLUSION PMA, a PKC activator, can upregulate the expression of both sTRAIL and mTRAIL in Jurkat cells, and the two forms of TRAIL have cytotoxic activity.
