(Submitter supplied) Wnt signaling contributes to the reprogramming and maintenance of cancer stem cell (CSC) states that is activated by the epithelial-mesenchymal transition (EMT) program. However, the mechanistic relationship between the EMT and Wnt pathway in CSCs remains unclear. Chromatin immunoprecipitation with high-throughput sequencing (ChIP-seq) indicated that EMT induces a switch from the β-catenin/E-cadherin/Sox15 complex to the β-catenin/Twist1/TCF4 complex, which then binds to CSC-related gene promoters. more...

(Submitter supplied) CD133 is expressed by a subpopulation of human fetal hair follicle placode cells during early hair development. Its expression, which is gradually lost as the placode matures, correlates with early morphogenesis. We used microarrays to analyze differences in gene expression between alpha-6 integrin+CD133+ basal cells and other human fetal epidermal populations to provide candidates defining this unique hair follicle placode subpopulation.

(Submitter supplied) In epithelial ovarian cancer (EOC), acquisition of invasiveness is accompanied by the loss of the epithelial features and the gain of a mesenchymal phenotype, a process known as epithelial-mesenchymal transition (EMT). Understanding the regulation of cell behavior during EMT is crucial for identifying the molecular mechanisms of EOC dissemination. Previously we identified the mannose receptor LY75 as the cellular phenotype modulator. more...

(Submitter supplied) Analysis of BRMS1 KD-induced EMT in non-samll cell lung cancer at gene expression level. The hypothesis tested in the present study was that BRMS1 KD induces EMT through differential regulation of EMT genes and Twist1 KD restores the epithelial phenotype in cells with BRMS1 KD. Results provide important information of biological functions in lung cancer which BRMS1 KD involves in, such as EMT, signaling, biological adhesion, immune system process, response to stimulus, and so on.

(Submitter supplied) We use gene expression data to provide a three-faceted analysis on the links between molecular subclasses of glioblastima, epithelial-to mesenchymal transition (EMT) and CD133 cell surface protein. The contribution of this paper is three-folded: First, we used a newly identified signature for epithelial-to-mesenchymal transition in human mammary epithelial cells, and demonstrated that genes in this signature have significant overlap with genes differentially expressed in all known GBM subtypes. more...

(Submitter supplied) SW480 cells overexpressing BOP1, CKS2 or NFIL3 migrated more actively compared to Control cells. Migration induced by BOP1, CKS2 or NFIL3 was repressed by interfering with distinct signaling systems using small- molecular-weight inhibitors, i.e., interference with PI3K, JNK and Notch in the case of BOP1, with PI3K and p38 MAPK in the case of CKS2, as well as with PI3K, p38 and mTOR in the case of NFIL3. more...

(Submitter supplied) TIMP-2 is an endogenous angiogenesis inhibitor, i.e. inhibits endothelial cell proliferation and tumor angiogenesis. As a result, TIMP-2 inhibits tumor growth and progression to metastasis. Understanding, therefore, the mechanisms of TIMP-2-mediated tumor growth inhibition would provide further support on the use of TIMP-2 as a novel biological agent for cancer therapy. We used microarray analysis to determine the TIMP-2 and Ala+TIMP-2 transcriptional profiles of A549 cancer cells in order to understand how TIMP-2 inhibits tumor growth and angiogenesis.

(Submitter supplied) Injury to the epithelium is integral to the pathogenesis of many inflammatory lung diseases, and epithelial repair is a critical determinant of clinical outcome. However, the signaling pathways regulating such repair are incompletely understood. Herein, we used in vitro and in vivo models to define these pathways. Human neutrophils were induced to transmigrate across monolayers of human lung epithelial cells in the physiologic basolateral-to-apical direction to a gradient of fMLP. more...

(Submitter supplied) Deregulation of canonical Wnt/beta-catenin pathway is one of the earliest events in the pathogenesis of colon cancer. Mutations in APC or CTNNB1 (beta-catenin gene) are highly frequent in colon cancer and cause aberrant stabilization of b-catenin, which activates the transcription of Wnt target genes by binding to chromatin via the TCF/LEF transcription factors. Here we report an integrative analysis of genome-wide chromatin occupancy of b-catenin by chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-seq) and gene expression profiling by microarray analysis upon RNAi-mediated knockdown of beta-catenin in colon cancer cells (GSE53656).
