(Submitter supplied) Duplication of chromosomal arm 20q occurs in prostate, cervical, colon, gastric, bladder, melanoma, pancreas and breast cancer, suggesting that 20q amplification may play a key causal role in tumorigenesis. According to an alternative view, chromosomal instabilities are mainly a common side effect of cancer progression. To test whether a specific genomic aberration might serve as a cancer initiating event, we established an in vitro system that models the evolutionary process of early stages of prostate tumor formation; normal prostate cells were immortalized and cultured for 650 days till several transformation hallmarks were observed. more...

(Submitter supplied) Polycomb group (PcG) proteins are essential for accurate axial body patterning during embryonic development. PcG-mediated repression is conserved in metazoans and is targeted in Drosophila by Polycomb response elements (PREs). Targeting sequences in humans have not been described. While analyzing chromatin architecture in the context of human embryonic stem cell (hESC) differentiation, we discovered a 1.8kb region between HOXD11 and HOXD12 (D11.12) that is associated with PcG proteins, is nuclease hypersensitive, and shows alteration as hESCs differentiate. 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) Epithelial-to-mesenchymal transition (EMT) is a dynamic process that relies on cellular plasticity; an EMT/MET axis is critical for metastatic colonization of carcinomas. Unlike epithelial programming, regulation of mesenchymal programming is not well understood in EMT. Here we describe the first microRNA that enhances exclusively mesenchymal programming. We demonstrate that microRNA-424 is up-regulated early during a TWIST1/SNAI1-induced EMT, and that it causes cells to express mesenchymal genes without affecting epithelial genes, resulting in a mixed/intermediate EMT. more...
