Reciprocal Reprogramming of Cancer Cells and Associated Mesenchymal Stem Cells in Gastric Cancer.

Project description:We utilized gastric cancer cells (GSC1) to demonstrate subversion of naïve Mesenchymal Stem Cells (MSC) from adjacent tissue, which are reprogrammed to express a tumor-promoting phenotype, whose cardinal manifestation is to sustain cancer stem cells. Paracrine effects of such primed MSC are sufficient to enable 2D growth of GSC1, while cell-cell interactions are necessary for 3D growth or in vivo tumor formation. Increased expression of R-spondin in primed MSC mediated elevation of Lgr5 expression in GSC1, activation of the WNT/β-catenin signaling pathway and translocation of β-catenin into the nucleus of most Lgr5 positive cells. Subversion of MSC in the tumor microenvironment (TME) by cancer cells, appears to be a prominent means to sustain the cancer stem cell underpinning of tumor progression.

Reciprocal Reprogramming of Cancer Cells and Associated Mesenchymal Stem Cells in Gastric Cancer.

Project description:The interactions of cancer stem cells (CSCs) within the tumor microenvironment (TME), contribute to the overall phenomenon of intratumoral heterogeneity, which also involve CSC interactions with noncancer stromal cells. Comprehensive understanding of the tumorigenesis process requires elucidating the coordinated gene expression between cancer and tumor stromal cells for each tumor. We show that human gastric cancer cells (GSC1) subvert gene expression and cytokine production by mesenchymal stem cells (GSC-MSC), thus promoting tumor progression. Using mixed composition of human tumor xenografts, organotypic culture, and in vitro assays, we demonstrate GSC1-mediated specific reprogramming of "naïve" MSC into specialized tumor associated MSC equipped with a tumor-promoting phenotype. Although paracrine effect of GSC-MSC or primed-MSC is sufficient to enable 2D growth of GSC1, cell-cell interaction with GSC-MSC is necessary for 3D growth and in vivo tumor formation. At both the transcriptional and at the protein level, RNA-Seq and proteome analyses, respectively, revealed increased R-spondin expression in primed-MSC, and paracrine and juxtacrine mediated elevation of Lgr5 expression in GSC1, suggesting GSC-MSC-mediated support of cancer stemness in GSC1. CSC properties are sustained in vivo through the interplay between GSC1 and GSC-MSC, activating the R-spondin/Lgr5 axis and WNT/β-catenin signaling pathway. β-Catenin+ cell clusters show β-catenin nuclear localization, indicating the activation of the WNT/β-catenin signaling pathway in these cells. The β-catenin+ cluster of cells overlap the Lgr5+ cells, however, not all Lgr5+ cells express β-catenin. A predominant means to sustain the CSC contribution to tumor progression appears to be subversion of MSC in the TME by cancer cells. Stem Cells 2018 Stem Cells 2019;37:176-189.

Gastric cancer ascites proteome

Project description:Gastric cancer is one of the most lethal malignancies with high mortality and gastric cancer-specific biomarker is need due to the lack of specific method for early screening, diagnosis, and prognosis of the patients with gastric cancer. Ascites is known for an important source for conducing biomarker discovery because it contains the secreted proteins from malignant cells, growth factors, and cytokines. In this study, we have conducted a comprehensive proteome study using ascites of patients with inflammatory diseases and gastric cancer. In the discovery stage, we have identified 2761 ascites-specific proteins, where 234 proteins were quantitated using the label free quantitation method, the normalized spectral abundance factor (NSAF); 152 and 82 proteins showed up and down-regulated pattern, respectively. Our ascites proteome can be used as baseline data for the discovery of novel biomarkers of the gastric cancer.

RNA-seq for gastric cancer and normal tissues/cells

Project description:We performed RNA-seq experiments to identify differentially expressed intergenic transcripts between gastric cancer and normal tissues/cells. Three primary cell culture samples from gastric cancer tissues, three gastric cancer cell lines and two normal tissue samples were used for the experiments.

Clinical molecular subtyping reveals intrinsic mesenchymal reprogramming in gastric cancer cells.

Project description:The mesenchymal cancer phenotype is known to be clinically related to treatment resistance and a poor prognosis. We identified gene signature-based molecular subtypes of gastric cancer (GC, n = 547) based on transcriptome data and validated their prognostic and predictive utility in multiple external cohorts. We subsequently examined their associations with tumor microenvironment (TME) features by employing cellular deconvolution methods and sequencing isolated GC populations. We further performed spatial transcriptomics analysis and immunohistochemistry, demonstrating the presence of GC cells in a partial epithelial-mesenchymal transition state. We performed network and pharmacogenomic database analyses to identify TGF-β signaling as a driver pathway and, thus, a therapeutic target. We further validated its expression in tumor cells in preclinical models and a single-cell dataset. Finally, we demonstrated that inhibition of TGF-β signaling negated mesenchymal/stem-like behavior and therapy resistance in GC cell lines and mouse xenograft models. In summary, we show that the mesenchymal GC phenotype could be driven by epithelial cancer cell-intrinsic TGF-β signaling and propose therapeutic strategies based on targeting the tumor-intrinsic mesenchymal reprogramming of medically intractable GC.

Gene expression profile of gastric cancer stem cells after CD44 knockdown

Project description:We did the microarray to further compare the changes of gene expression between gastric cancer stem cells with CD44 knockdown by lentivirus and gastric cancer stem cells by scamble short hairpin RNA. Gastric cancer stem cells (Lentivirus) were infected with lentivirus that expressed human CD44-speciï¬c short hairpin RNA (shRNA). Control group of gastric cancer stem cells (Vector group) were only infected with scramble shRNA.
