Project description:To understand the molecular process associated with tissue morphogenesis of pancreatic epithelial cells, we profiled the transcriptomes of normal or malignant pancreatic organoids formed in three-dimenstional reconsitututed basement membrance (rBM). Cell monolayers cultured on rBM-coated culture plastics were used as controls. HPDE (immortalized pancreatic epithelial cells) and PANC-1 cells (pancreatic cancer cells) were seeded on reconstituted basement membrane (rBM)-coated culture plastics or cultured on top of three-dimensional (3D) rBM gels. Total RNA samples were collected from cell monolayers or 3D cell clusters (formed at day 2), pancreatic tubules or tumor spheroids (formed at day 6) in the rBM culture, followed by global gene expression profiling.

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). 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:To conduct comparative transcriptomic analyses on normal or malignant prostate epithelial cells in response to tissue contextual changes, we cultured immortalized prostate epithelial cells or prostate cancer cells as cell monolayers or three-dimensional organoids and profiled their transcriptomes in respective culture contexts. RWPE-1 (immortalized prostate epithelial cells) and LNCaP cells (prostate cancer cells) were seeded on reconstituted basement membrane (rBM)-coated culture plastics or cultured within three-dimensional (3D) rBM gels. Total RNA samples were collected from cell monolayers or 3D cell clusters (formed at day 2) or acini or spheroids (formed at day 6) in the rBM culture, followed by global gene expression profiling.

Project description:Apo2L/TRAIL stimulates cancer-cell death through the proapoptotic receptors DR4 and DR5, but the determinants of tumor susceptibility to this ligand are not fully defined. mRNA expression of the peptidyl O-glycosyl transferase GALNT14 correlated with Apo2L/TRAIL sensitivity in pancreatic carcinoma, non-small cell lung carcinoma and melanoma cell lines (P < 0.00009; n=83), and up to 30% of samples from various human malignancies displayed GALNT14 overexpression. RNA interference of GALNT14 reduced cellular Apo2L/TRAIL sensitivity, whereas overexpression increased responsiveness. Biochemical analysis of DR5 identified several ectodomain O-GalNAc-Gal-Sialic acid structures. Sequence comparison predicted conserved extracellular DR4 and DR5 O-glycosylation sites; progressive mutation of the DR5 sites attenuated apoptosis signaling. O-glycosylation promoted ligand-stimulated clustering of DR4 and DR5, which mediated recruitment and activation of the apoptosis-initiating protease caspase-8. These results uncover a novel link between death receptor O-glycosylation and apoptosis signaling, providing potential predictive biomarkers for Apo2L/TRAIL-based cancer therapy.

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 “death” 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.

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.
