K., H. K. L., W. S. P., S. Y. K., J. H. L., S. Y. H., J. Y. P., R. R. O., J. Y. L., N. J. DcR1 and DcR2 expression was restored in all 9 methylated cell lines tested after treatment. (5) Methylation positive lung cancer cell line DNAs (after methylation had been confirmed through DNA sequencing) were used as a positive control for methylated alleles. Epigenetic regulation of cell life and death decisions and deregulation in cancer. 20 Here, we report that DcR2 is a p53 target gene and regulates chemosensitivity. . It remains to be determined if the other TRAIL receptor genes are also mutated in some cancers … TNFRSF10C 8, Similarly the frequencies of methylation in other tumor types were comparable or higher than the rate reported previously for neuroblastomas.20 Interestingly, occasional methylation was found in non‐malignant breast tissue from some of the breast cancer cases. TRAIL receptor 2 (TRAIL-R2) Synonyms: ZTNFR9; UNQ160/PRO186; Tumor necrosis factor receptor superfamily member 10B; TRICK2; TRAILR2; TNF-related apoptosis-inducing ligand receptor 2; KILLER; Death receptor 5; DR5; CD262. In the current study, all 10 TRAIL-R2 mutations in the coding sequences were identified in this conserved area, suggesting that the mutations might disrupt TRAIL-induced death signaling. ⇓ Apoptotic Pathways as Targets for Novel Therapies in Cancer and Other Diseases. Water blanks were included with each assay. Altmetric Badge. Genetic and epigenetic inactivation of TNFRSF10C in human prostate cancer. We found high frequencies of DcR1and DcR2 methylation in tumor tissues and rarely in non‐malignant tissue. Aberrant methylation in non-small cell lung cancer. Increased sensitivity to TRAIL in cell lines and increased survival of MM and prostate cancer patients with loss of gene expression or methylation support this concept. Overall, 48 of 104 cases (46%) were informative for at least one of the four polymorphisms, and 18 of 48 (37%) informative cases showed LOH with one or more polymorphic loci. Gene methylation in pleural mesothelioma: Correlations with clinico-pathological features and patient's follow-up. Targeting Death Receptors in Bladder, Prostate and Renal Cancer. We failed to detect methylation of DR4 and DR5 in any of the cell lines or tumors (except for 2 small cell lung cancer cell lines, 2 neuroblastomas, 2 retinoblastomas and 2 prostate tumors), suggesting that DR4 or DR5 methylation are not involved in the pathogenesis of most or all tumors supporting our previous findings.19 Silencing of these receptors may occur in some tumors such as small cell lung cancer by other mechanisms. Aberrant methylation frequency of TNFRSF10C Promoter in pancreatic cancer cell lines. DNA methylation profile of 28 potential marker loci in malignant mesothelioma.

Genomic DNA from normal lymphocytes or tumor cells was amplified with 15 primer pairs covering the entire coding region (nine exons) of the TRAIL-R2 gene, which were the same primers described by Arai et al. Recently aberrant methylation of TRAIL decoy receptors was reported in pediatric tumor cell lines and neuroblastomas. Pancreatic Cancer Resistance to TRAIL Therapy: Regulators of the Death Inducing Signaling Complex. TRAIL is known to bind to 4 different receptors, 2 proapoptotic ( DR4 and DR5 ), and 2 potentially antiapoptotic receptors lacking death domains ( DcR1 and DcR2 ). In vivo, systemically administered TRAIL is not only tumoricidal in mice but is also nontoxic , the overexpression of inhibitory proteins in signal transduction pathways such as FLICE-inhibitory protein Cell survival was quantitated using MTS assay.19 Sensitivity to TRAIL was measured as percentage survival compared to the untreated controls.

Sanguinarine-Mediated Sensitization of Cervical Cancer SiHa Cells to TRAIL. Frontiers in Cell and Developmental Biology. Thus, we are still left to explain how silencing of decoy receptors could favor tumorigenesis. A recent report also indicated that the loss of TRAIL-R2 protein expression and the shift of cell-surface TRAIL-R2 expression to the cytoplasm are related to TRAIL resistance in cancer cells 4, 4) (1, All statistical tests were 2‐sided. and Internal Medicine [J. Y. H.], and Cancer Research Institute [S. H. L., W. S. P., J. Y. L., N. J. Total RNA was extracted from the cell lines with Trizol (Life Technologies, Rockville, MD) following the manufacturer's instructions. We focused on 5 lung cancer cell lines reported in our previous publication19 that were positive for expression of all DISC components but positive or negative for the expression of decoy receptors (NCI‐H460, NCI‐H1339 negative for both DcR1 and DcR2; NCI‐H1703, NCI‐H2195 positive for DcR1 but negative for DcR2 whereas NCI‐H2347 positive for both DcR1 and DcR2). Prediction of TRAIL sensitivity in cancer cell lines. Transient expression and quantitative binding studies show TRAIL-R3 to be a plasma membrane-bound protein capable of high affinity interaction with the TRAIL ligand. 9, The bands of the wild-type alleles in the latter eight cases could result from contamination by normal tissue, but we used a micrometrically precise, microdissection technique using a micromanipulator (Fig. 3, 2B) 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. .

TRAIL-R3 encodes a 299 amino acid protein with 58 and 54% overall identity to TRAIL-R1 and -R2, respectively. . Analysis of data pertaining to expression of decoy receptors and TRAIL sensitivity (in terms of % survival) showed a mean survival of 12% for 2 lines lacking expression of both receptors, 21% for 2 cell lines lacking DcR1 expression and 50% for a cell line expressing both receptors (Table II). . ⇓ The nonsense mutation showed a point mutation introducing premature termination signal at codon 354 (Fig. In tumor and nonmalignant samples, most of which consist of mixtures of tumor cells and non‐malignant cells, either the unmethylated band only or both methylated and unmethylated bands were present. None of the normal or non‐malignant tissues showed methylation of DR4 or DR5 (Table I). The genes for the four TRAIL receptors are tightly clustered on human chromosome 8p21–22 [46–48], suggesting they evolved relatively recently via gene duplication. We also microdissected infiltrating lymphocytes for corresponding normal DNA from the same slide in all cases. 10) Complete or nearly complete absence of one allele in tumor DNA of informative cases, as defined by direct visualization, was considered as LOH. Cells were treated with recombinant TRAIL (100 ng/ml) for 48 hr.
