trail receptor gene

4) High TRAIL-R4 decoy receptor expression in BPH, OCPCa and APCa cases might complicate TRAIL mediated gene therapy approaches, as previously demonstrated in in vitro settings.13, 14 Interestingly chemotherapy agents17, 18 and ionizing radiation 19 augment TRAIL induced apoptosis in prostate cancer cells through death receptor up-regulation. Copyright © 2021 by the American Association for Cancer Research. (5, Total RNA was extracted from the cell lines with Trizol (Life Technologies, Rockville, MD) following the manufacturer's instructions. The platelet-derived growth factor-receptor-B-like tumor suppressor gene has been isolated from a region commonly deleted in NSCLCs and hepatocellular and colorectal carcinomas Discovery of DNA methylation markers in cervical cancer using relaxation ranking. Final extension was continued for 5 min at 72°C. Its activity may be modulated by binding to the decoy receptors TNFRSF10C/TRAILR3, TNFRSF10D/TRAILR4 and TNFRSF11B/OPG that cannot induce apoptosis. . C, addition of TRAIL causes a structural reorganization from a preligand state to the ligand-induced trimer state, as inferred by the trimeric ligand-bound crystal structure, as shown in A. SSCP of DNA from tumor (T) of case 42 shows only two aberrant bands (arrows) without any wild-type bands when compared with SSCP from normal lymphocytes (N). , but the expression of these proteins does not necessarily predict susceptibility to killing We characterised DNA methylation and gene expression of four tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) receptors DR4, DR5, DcR1 and DcR2 in three choriocarcinoma (JAR, JEG-3, BeWo) and two transformed (HTR-8/SVneo and HPT-8) cell lines. Hepatobiliary & Pancreatic Diseases International. Its expression, like the other three TRAIL receptors (i.e., DR4, DR5, and DcR1), is regulated by p53. Through the microdissection technique, we selectively procured tumor cells from histological sections of 104 NSCLCs (Fig. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. In contrast, the other nine cases showed that the bands of the wild-type allele were present together with aberrant bands of the mutant allele (Fig. Cells were cultured in RPMI medium supplemented with 5% FBS at 37°C with 5% CO2. In this study, we show that retinoids sensitize cancer cells to TRAIL-induced apoptosis by upregulating expression of TRAIL-R1. Chromosome 8p21-22 is a frequent site of allelic deletions in many types of human tumors, including non-small cell lung cancer (NSCLC). . 7, Aberrant methylation of DcR2 was found in 17 of 23 (74%) breast cancer in 13 of 27 (48%) lung cancer and in 5 of 7 (71%) MM cell lines (Table I, Fig. We also carried out MSP on tumor samples and non‐malignant tissues. TRAIL based therapy utilizes two types of pharmacological agents, rhTRAIL and mAbs against TRAIL-Rs. There is a G-to-A transition at nucleotide 1062 (arrow) in tumor tissue compared with normal tissue. The first two authors contributed equally to this work. Cross-Platform Array Screening Identifies COL1A2, THBS1, TNFRSF10D and UCHL1 as Genes Frequently Silenced by Methylation in Melanoma. H290 and Hp1 represent mesothelioma cell lines. Upon engagement by their respective ligands, tumor necrosis factor receptor 1 and Fas recruit adaptor molecules and activate a cascade of cysteine proteases (caspases), the proteolytic activity of which results in apoptosis. 2D) Treatment with 5‐Aza‐CdR restored expression of DcR1 and DcR2 in all methylated cell lines tested. Treatment with 5‐aza‐2′‐deoxycytidine restored DcR1 and DcR2 expression in 9 methylated cell lines confirming that aberrant methylation was the cause for silencing of DcR1 and DcR2 expression. Receptor for the cytotoxic ligand TNFSF10/TRAIL (PubMed:26457518). Treatment with 5‐Aza‐CdR restored DcR1 and DcR2 expression in methylated cell lines, confirming that methylation was responsible for silencing of DcR1 and DcR2 expression. Enter multiple addresses on separate lines or separate them with commas. Genetic and epigenetic inactivation of TNFRSF10C in human prostate cancer. RETRACTED: Methylation of apoptosis related genes in the pathogenesis and prognosis of prostate cancer. Phase 1b‐2a study to reverse platinum resistance through use of a hypomethylating agent, azacitidine, in patients with platinum‐resistant or platinum‐refractory epithelial ovarian cancer. We tried to correlate methylation status with clinical features of patients including survival and histological type in lung breast MM and prostate cancer. For methylated cell lines the loss of DcR1 was found in 8 of 11 (73%) breast cancer cell lines, in 10 of 10 (100%) lung cancer cell lines and in 3 of 3 (100%) MM cell lines. Cancer Research Online ISSN: 1538-7445 , indicating that the microdissected tumor samples were nearly devoid of contamination by normal tissue. RT‐PCR for DcR2 expression in cell lines. None of the normal or non‐malignant tissues showed methylation of DR4 or DR5 (Table I). 4) Assessment of gene promoter hypermethylation for detection of cervical neoplasia. TRAIL (also known as Apo-2L) is a member of the tumor necrosis factor (TNF) ligand family that rapidly induces apoptosis in a variety of transformed cell lines. This observation suggests that methylation may commence before tumor formation and may represent a field effect. 1b). (24) ⇓ The TRAIL‐activated DR4 (also TNFRSF10A, Apo‐2, TRAIL‐R1)1, 2 and DR5 (also TNFRSF10B, KILLER/DR5, TRICK2, TRAIL‐R3) receptors2, 3, 4 have also been shown to initiate a caspase‐mediated apoptotic pathway.4 Death inducing DR4 and DR5 and the decoy receptors DcR1 (also TNFRSF10C, TRID, TRAIL‐R3) and DcR2 (also TNFRSF10D, TRUNDD, TRAIL‐R4) are structurally related, especially in their extracellular domains and are all located at 8p 21–22.5, 6 Decoy receptor DcR1 completely lacks the intra‐cellular death domain and DcR2 contains a truncated, nonfunctional death domain and appear unable to induce apoptosis. 2, A and B) , 4) (5) Additionally, gene therapy approaches using TRAIL-encoding adenovirus (Ad-TRAIL) are currently being developed to overcome the limitations inherent to TRAIL receptor targeting, i.e., pharmacokinetic of soluble TRAIL, pattern of receptor expression, and tumor cell resistance. Prediction of TRAIL sensitivity in cancer cell lines. J:55627 Wu GS, et al., Molecular cloning and functional analysis of the mouse homologue of the KILLER/DR5 tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) death receptor. 2, Tumor necrosis factor-related apoptosis-inducing ligand-receptor 2 (TRAIL-R2) is a cell-surface receptor involved in cell death signaling. One of the mutations (case 5) is predicted to cause premature termination of protein synthesis, and hence resembles typical loss-of-function mutations. Targeting Death Receptors in Bladder, Prostate and Renal Cancer. DNA Methylation in Promoter Region as Biomarkers in Prostate Cancer. We also microdissected infiltrating lymphocytes for corresponding normal DNA from the same slide in all cases. Positive control, RNA from normal lung; negative control, water blank. TRAIL R3/DcR1, R4/DcR2 and soluble decoy osteoprotegerin are truncated without a ‘death domain’, prevent cell apoptosis,2 but may result in non-canonical signalling through the receptor-interacting serine/threonine-protein kinase 1, TNF receptor-associated factor 2 and inhibitor of NF-κ subunit gamma.4 Genetic variation in the TNFSF10 gene has been associated with asthma, but … CpG island promoter hypermethylation of the pro-apoptotic gene caspase-8 is a common hallmark of relapsed glioblastoma multiforme. . . ], Sign In to Email Alerts with your Email Address. (14 Cancer Res. TRAIL receptor gene editing unveils TRAIL-R1 as a master player of apoptosis induced by TRAIL and ER stress. . , 13) ⇓ Mutations at position −1 of the consensus sequence of the acceptor site of an intron have been shown to cause cryptic splice site utilization and exon skipping in various human disease genes Clearly therefore, studies are now needed that attempt to find another gene alterations at this region, including TRAIL-R1. PCR products were visualized on 2% agarose gels stained with ethidium bromide. The reaction mixture was denatured for 1 min at 94°C and incubated for 30 cycles (denaturing for 40 s at 94°C, annealing for 40 s at 59–68°C, and extension for 40 s at 72°C).
