Project description:Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been shown to be a potent inducer of apoptosis in various cancer cell lines and primary cancer cells. However, in clinical trials administration of recombinant TRAIL or TRAIL death receptor agonists did not show sufficient efficacy for treatment of tested malignant disorders compared to standard chemotherapy. Acquired resistance of cancer cells to TRAIL and to other âdeath receptorâ ligands may explain not only the inability of TRAIL and TRAIL âdeath receptorâ agonists to achieve the clearance of cancer cells in vivo but also the escape of cancer cells from immune cell â mediated killing. Selective pressure of TRAIL on TRAIL-sensitive Jurkat T-lymphoblastic leukemia cells provided several TRAIL resistant Jurkat cell line clones (TR1, TR2, TR3). Irrespective of molecular changes histone deacetylase inhibitors (HDACi), such as suberoylanilide-hydroxamic acid (SAHA, vorinostat), were able to restore sensitivity of all three TRAIL-resistant clones to TRAIL. Gene expression analysis of TR1 clone treated with SAHA 1microM for 12 hours compared to untreated TR1 clone showed significant decrease in expression of CFLAR/cFLIP (0.71; p=0.006), BIRC5/survivin (0.80; p=0.024) and BID (0.66; p<0.001). Expression of both TRAIL âdeathâ receptors DR4 (1.57; p<0.001) and DR5 (1.47; p=0.002) were significantly increased compared to untreated TR1 cells. The mRNA expression of caspases-2,-3,-8,-9,-10 did not significantly change with the SAHA treatment. Total cellular RNA was isolated from biologic duplicates of untreated Jurkat cells (WT), TRAIL resistant Jurkat cell clone (TR1) and 1 µM and 0.5 µM suberoylanilide-hydroxamic acid (SAHA, vorinostat) treated TR1 cell clones for 12 hours. Jurkat cell line subclones TR1was established by selective pressure of TRAIL 1000 ng/mL on Jurkat cells over the period of 12 weeks.

Selective pressure of TRAIL on TRAIL-sensitive Jurkat T-lymphoblastic leukemia cells provided several TRAIL resistant Jurkat cell line clones (TR1, TR2, TR3). We showed that acquired TRAIL resistance was associated with complex disruption of both extrinsic and intrinsic apoptotic pathways manifested by acquired multi-drug resistant phenotype of TR1, TR2, and TR3 clones. To identify changes associated with TRAIL resistance of Jurkat cells we performed genome-wide gene expression analysis of TRAIL-resistant clones (TR) and compared to WT Jurkat cells. We identified significantly increased expression (1.33-fold change with adjusted p < 0.05) of 73 genes in TR1 clone, 53 genes in TR2 clone and 8 genes in TR3 clone, and significant decrease in expression (0.75-fold change with adjusted p < 0.05) of 174 genes in TR1 clone, 36 genes in TR2 clone and 28 genes in TR3 clone. There was an overlap of only 2 significantly overexpressed (midkine / MDK and zinc finger and BTB domain containing 16 gene / ZBTB16 / PLZF) and 4 downregulated genes (YAP1, IGJ, EIF1AY, RPS4Y1) in all three TR clones. Total cellular RNA was isolated from biologic duplicates of untreated Jurkat cells (WT) and TRAIL resistant Jurkat cell line subclones (TR1, TR2, TR3) established by selective pressure of TRAIL 1000 ng/mL on Jurkat cells over the period of 12 weeks.

Project description:Death receptor-mediated hepatocyte apoptosis is implicated in a wide range of liver diseases including viral hepatitis, alcoholic hepatitis, ischemia/reperfusion injury, fulminant hepatic failure, cholestatic liver injury and cancer. Deletion of NF-ĸB essential modulator in hepatocytes (NemoΔhepa) causes the spontaneous development of hepatocellular carcinoma preceded by steatohepatitis in mice and thus serves as an excellent model for the progression from chronic hepatitis to liver cancer. In the present study we aimed to dissect the death-receptor mediated pathways that contribute to liver injury in NemoΔhepa mice. Therefore, we generated NemoΔhepa/TRAIL-/- and NemoΔhepa/TNFR1-/- animals and analyzed the progression of liver injury. NemoΔhepa/TRAIL-/- displayed a similar phenotype to NemoΔhepa mice characteristic of high apoptosis, infiltration of immune cells, hepatocyte proliferation and steatohepatitis. These pathophysiological features were significantly ameliorated in NemoΔhepa/TNFR1-/- livers. Hepatocyte apoptosis was increased in NemoΔhepa and NemoΔhepa/TRAIL-/- mice while NemoΔhepa/TNFR1-/- animals showed reduced cell death concomitant with a strong reduction in pJNK levels. Cell cycle parameters were significantly less activated in NemoΔhepa/TNFR1-/- livers. Additionally, markers of liver fibrosis and indicators of tumour progression were significantly decreased in these animals. The present data demonstrate that the death receptor TNFR1 but not TRAIL is important in determining progression of liver injury in hepatocyte-specific Nemo knockout mice.

Project description:Senescent cells secrete a plethora of factors with potent paracrine signaling capacity. Strikingly, senescence, which acts as a defense against cell transformation, exerts pro-tumorigenic activities through its secretome by promoting numerous tumor-specific features, such as cellular proliferation, epithelial-mesenchymal transition and invasiveness. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has the unique activity of activating cell death exclusively in tumor cells. Given that the senescence-associated secretome supports cell transformation, we asked whether factor(s) of this secretome would establish a program required for the acquisition of TRAIL sensitivity. We found that conditioned media from several types of senescent cells (CMS) efficiently sensitized pre-transformed cells to TRAIL, while the same was not observed with normal or immortalized cells. Dynamic transcription profiling analysis of CMS-exposed pre-transformed cells revealed paracrine autoregulatory loop of senescence-associated secretome factors and a dominant role of CMS-induced MYC. Sensitization to TRAIL coincided with MYC upregulation and massive changes in gene regulation. CMS-induced MYC silenced its target gene CFLAR, encoding the apoptosis inhibitor FLIPL, thus leading to the acquisition of TRAIL sensitivity. Altogether, our results reveal that senescent cell-secreted factors exert a TRAIL sensitizing effect on pre-transformed cells by modulating the expression of MYC and CFLAR. Notably, CMS dose-dependent sensitization to TRAIL was observed with TRAIL-insensitive cancer cells and confirmed in co-culture experiments. Dissection and characterization of TRAIL-sensitizing CMS factors and the associated signaling pathway(s) may provide a mechanistic insight in the acquisition of TRAIL sensitivity and lead to novel concepts for the apoptogenic therapy of pre-malignant and TRAIL-resistant tumors. Pre-transformed BJEL cells were incubated with CMS for 0, 1, 3, 6, 8, 16 or 24 h respectively. Total RNA has been extracted from each time point and used for gene expression analysis (Affymetrix Human Gene 1.0 ST Arrays).

Project description:T cells are the primary target of the virus HIV-1. Upon infection, the expression of the virus may come to a complete shutdown, a phenomenon known as latency. The molecular mechanisms responsible for the latency of HIV-1 are still poorly understood. To shed light on those mechanisms, we used the J-Lat A2 model for latency reversal, that consists of a Jurkat T cell clone containing a mini HIV construct that is transcriptionally silent. We treated J-Lat A2 and Jurkat cells with the latency-reversing drugs SAHA (suberoylanilide hydroxamic acid) and PMA (phorbol 12-myristate 13-acetate), and we performed single-cell RNA-seq to identify transcriptional signatures shared among the cells where HIV is reactivated.

Project description:Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising agent in selectively killing tumor cells. However, TRAIL monotherapy is not especially successful due to the fact that many cancer cells are resistant to TRAIL. Chemotherapeutic agents, such as doxorubicin have been shown to act synergistically with TRAIL on cancer cells, but the exact mechanisms of actions are poorly understood. In this study we performed high-throughput siRNA screening and genome-wide gene expression profiling on doxorubicin treated U1690 cells to explore novel mechanisms underlying doxorubicin-TRAIL synergy. The screening and expression profiling results were integrated and dihydroorotate dehydrogenase (DHODH) was identified to be a potential candidate. DHODH is rate-limiting enzyme in the pyrimidine synthesis pathway, and its expression was downregulated by doxorubicin and silencing of DHODH sensitized U1690 cells to TRAIL. Inhibition of DHODH activity by brequinar dramatically increased the sensitivity of U1690 cells to TRAIL-induced apoptosis, and was accompanied by downregulation of cFLIPL and mitochondrial depolarization. However, the expressions of DR4 and 5 were not changed in response to brequinar treatment in contrast to doxorubicin. In addition, uridine, an end product of the pyrimidine synthesis pathway was able to rescue the sensitization effects initialized by both brequinar and doxorubicin. Furthermore, other cancer cell lines, LNCaP, MCF-7 and HT-29 were also shown to be sensitized to TRAIL by brequinar. Taken together, our findings have identified a novel drug, brequinar, to be potentially utilized in TRAIL combinatorial cancer therapy and highlighted for the first time the importance of DHODH and pyrimidine pathway in mediating TRAIL sensitization in cancer cells. Total RNA obtained from small cell lung cancer U1690 cells either treated with DMSO control or 1 M-BM-5M doxorubicin for 12 or 24h.

Project description:In this study, we subjected the phenomenon of fractional killing in a clonal population of TRAIL-sensitive cells to careful analysis. We asked whether cells that survive initial exposure to TRAIL are sensitive or resistant to subsequent treatment with TRAIL or other apoptosis-inducing agents. We observed that TRAIL survivor cells were highly resistant to a subsequent treatment with TRAIL 24hr later but that this resistance disappeared following several days in culture. Resistance did not involve downregulation of TRAIL receptors and extended to death ligands that bind different classes of receptors: TRAIL survivors were transiently resistant to FasL and vice versa. Gene expression analysis revealed that NF-kB-mediated inflammatory genes were activated in transiently resistant survivor cells leading to an inflammatory phenotype, but resistance was mediated by an independent mechanism related to changes in signaling at the DISC. Periodic exposure to TRAIL sustained resistance, demonstrating a component of induced survival signaling leading to transient acquired resistance to TRAIL. Based on these results we propose that TRAIL treatment leads to a transient adaptation in survivor cells that can be sustained in cells exposed to long-term TRAIL treatments, leading to acquired resistance. Minimizing the impact of cell-to-cell variability on TRAIL-mediated killing will thus require appropriate spacing of stimuli as well as the use of additional agents that inhibit pro-survival pathways.
