Project description:Employing Cre/loxP technology, a mouse model of liver specific Cdh1 (E-cadherin) depletion was created (fl/fl | +/wt). Previously, the mice had already been compared to littermates with normal Ecadherin levels (fl/fl | wt/wt), using a broad range of laboratory methods (Serum parameters, long-term weight analysis, histology, western blot, etc.). To analyze the effect of Cdh1 (E-Cadherin) depletion on the liver homeostasis on the RNA-level over the course of 3 time-points, liver tissue was aquired from mice groups aged 1 week, 3 weeks and 6 weeks.

Project description:Background: E-cadherin is an adherens junction protein that forms homophilic intercellular contacts in epithelial cells while also interacting with the intracellular cytoskeletal networks. It has roles including establishment and maintenance of cell polarity, differentiation, migration and signalling in cell proliferation pathways. Its downregulation is commonly observed in epithelial tumours and is a hallmark of the epithelial to mesenchymal transition (EMT). Methods: To improve our understanding of how E-cadherin loss contributes to tumorigenicity, we investigated the impact of its elimination from the non-tumorigenic breast cell line MCF10A. We performed cell-based assays and whole genome RNAseq to characterize an isogenic MCF10A cell line that is devoid of CDH1 expression due to an engineered homozygous 4bp deletion in CDH1 exon 11. Results: The E-cadherin-deficient line, MCF10A CDH1-/- showed subtle morphological changes, weaker cell-substrate adhesion, delayed migration, but retained cell-cell contact, contact growth inhibition and anchorage-dependent growth. Within the cytoskeleton, the apical microtubule network in the CDH1-deficient cells lacked the radial pattern of organization present in the MCF10A cells and F-actin formed thicker, more numerous stress fibres in the basal part of the cell. Whole genome RNAseq identified compensatory changes in the genes involved in cell-cell adhesion while genes involved in cell-substrate adhesion, notably ITGA1, COL8A1, COL4A2 and COL12A1, were significantly downregulated. Key EMT markers including CDH2, FN1, VIM and VTN were not upregulated although increased expression of proteolytic matrix metalloprotease and kallikrein genes was observed. Conclusions: Overall, our results demonstrated that E-cadherin loss alone was insufficient to induce an EMT or enhance transforming potential in the non-tumorigenic MCF10A cells but was associated with broad transcriptional changes associated with tissue remodelling. Examination of the impact of E-cadherin (CDH1) loss in an isogenic pair of breast cell lines.

Project description:Esophageal cancer is one of the deadliest cancers as patients present at late stages of disease. Frequent gene alterations include the loss of E-cadherin and TGFb receptor type II. The goal of this study was to establish a model of esophageal cancer by introducing dominant-negative mutants of E-cadherin and TGFb receptor II. To analyze the functional consequences and gene expression chages induced by E-cadherin and TGFb receptor type II loss in esophageal cancer.

Project description:BRAF-inhibitor (BRAFi)-resistance compromises long term survivorship of malignant melanoma patients, and mutant NRAS is a major mediator of BRAFi-resistance. We have employed NanoString nCounterTM transcriptomic analysis of isogenic human malignant melanoma cells that differ only by NRAS mutational status (BRAFi-sensitive A375-BRAFV600E/NRASQ61 versus BRAFi-resistant A375-BRAFV600E/NRASQ61K), identifying modulation of specific gene expression networks as a function of NRASQ61K-status.

Frequent gene alterations include the loss of E-cadherin and TGFb receptor type II. The goal of this study was to establish a model of esophageal cancer by introducing dominant-negative mutants of E-cadherin and TGFb receptor II. To analyze the functional consequences and gene expression chages induced by E-cadherin and TGFb receptor type II loss in esophageal cancer. Human esophageal keratinocytes were retrovirally transfected with wild-type full length E-cadherin, dominant-negative E-cadherin and dominant-negative TGFb receptor type II. Grown in organotypic cultures on a collagen/matrigel matrix with embedded fibroblast, the generated cell lines were analyzed for their potential to invade into the underlying matrix. Each cell lines was grown in duplicate in organotypic culture and therefore 2 replicates analyzed. Gene expression changes in invasive versus non-invasive areas were analyzed after RNA isolation using laser-capture microdissection resulting in 2 samples representing a normal esophageal epithelium (Ecad), 2 each of dominant-negative Ecad (Ecyto) non-invasive and invasive. To model the genetic alterations in esophageal cancer dominant-negative E-cadherin and dominant-negative TGFb receptor type II (Ecyto-dnTGFR) were expressed and 2 samples each, non-invasive and invasive, analyzed.
