(Submitter supplied) Genome-wide mRNA expression profiles of 200 primary gastric tumors from the Singapore patient cohort. Gastric cancer (GC) is the second leading cause of global cancer mortality, with individual gastric tumors displaying significant heterogeneity in their deregulation of various oncogenic pathways. We aim to identify major oncogenic pathways in GC that robustly impact patient survival and treatment response. more...

(Submitter supplied) To identify chromatin alterations in primary gastric adenocarcionomas, we performed nano-scale chromatin immunoprecipitation-sequencing (Nano-CHiPseq) of histone modifications in 5 gastric cancers and matched normal tissues, We identified hundreds of somatically-altered promoters (marked by H3K4me3) and enhancers (H3K4me1). The majority of cancer-associated promoters localized to genomic sites lacking previously-annotated transcription start sites (“cryptic promoters”), driving high expression of nearby genes implicated in gastrointestinal cancers, embryonic development, and tissue specification. more...

(Submitter supplied) Three transcription factors KLF5, GATA4 and GATA6 are recurrently amplified in multiple gastric cancer cohorts, representing one type of lineage-survival oncogenes in gastric cancer. ChIP-Seq analysis of these three factors in multiple cell lines revealed that significant number of genomic sites are co-occupied by KLF5 and GATA4 and/or GATA6. Integrative analysis of ChIP-Seq and gene expression identified several targets of the three transcription factors in both cell lines and primary tumors, including HNF4A. more...

(Submitter supplied) Genome-wide mRNA expression profiles of 70 primary gastric tumors from the Australian patient cohort. Like many cancers, gastric adenocarcinomas (gastric cancers) show considerable heterogeneity between patients. Thus, there is intense interest in using gene expression profiles to discover subtypes of gastric cancers with particular biological properties or therapeutic vulnerabilities. Identification of such subtypes could generate insights into the mechanisms of cancer progression or lay the foundation for personalized treatments. more...

Gastric cancer (GC) is the second leading cause of global cancer mortality, with individual gastric tumors displaying significant heterogeneity in their deregulation of various oncogenic pathways. We aim to identify major oncogenic pathways in GC that robustly impact patient survival and treatment response. We used an in silico strategy based on gene expression signatures and connectivity analytics to map patterns of oncogenic pathway activation in 25 unique GCCLs, and in 301 primary gastric cancers from three independent patient cohorts. more...

(Submitter supplied) An integrated profiling approach was performed to define molecular alterations associated to the aggressive behavior of retroperitoneal dedifferentiated liposarcoma. In particular, matched well and dedifferentiated components as well as normal adipose tissues, obtained from the same tumor sites, were comparatively investigated to higlight differences in gene expression.

(Submitter supplied) HMLE-SNAIL cell cultures were treated with KPT-185 drug (KPT, 150 nanomolar) or vehicle (DMSO) for 24 hours, in parallel quadruplicates. KPT-185 is an Exportin 1 (XPO1) inhibitor with possible pluripotent or unexpected effects on cell signaling. Total RNA was isolated and analyzed in an Agilent two-color experiment, where four biological replicates of each condition were directly compared, expression ratios are KPT-treated condition relative to control (DMSO vehicle-treated).

(Submitter supplied) The TP53 wild-type cell line JVM2, representing mantle cell lymphoma (MCL), was transduced to create control or TP53 knockdown (KD) forms. These were then either left untreated or treated with KPT-185, a selective inhibitor of nuclear export (SINE) by XPO1, for gene expression profiling (GEP). Consistent with the observation that KPT-185 was equally toxic to both forms, the majority of gene expression changes resulting from KPT-185 treatment were similar for both forms, even though TP53 is known to be one of the cargo proteins of XPO1. more...
