(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...

(Submitter supplied) SNAI1 is a key transcription factor in the EMT process, that is considered as the initial step of metastasis. The microRNAs(miRNAs) invovled in SNAI1-induced EMT may play important roles in regulating the process of metastasis. We used microarrays to establish the miRNAs both upregulated and downregulated in SNAI1-induced EMT process.

(Submitter supplied) To identify miRNAs participating in SNAI1-orchestrated regulatory pathways, we analysed time-resolved microarray data of SNAI1-induced EMT, obtained during conditional expression of SNAI1 in a “Tet-Off” MCF7-SNAI1 breast carcinoma cell model (Vetter et al, 2009).

(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.

Analysis of Myc-Cap prostate cancer (PC) cells overexpressing Twist1 and mutants F191G, AQA, and DQD. Twist1, a basic helix-loop-helix transcription factor, is a master regulator of EMT that promotes cancer metastasis. Results provide insight into molecular basis of Twist1-induced PC metastasis.

(Submitter supplied) PHF8 exerts distinct functions in different types of cancer. However, the mechanisms underlying its specific functions in each case remain obscure. To establish whether overexpression of PHF8 regulates the TGF-β induced the epithelial-mesenchymal transition (EMT), we treated MCF10A-Mock (control) and MCF10A-PHF8wt (overexpressing wild-type PHF8) cells with TGF-β1 for 0, 24, 48 and 72 hours and performed RNA-seq in biological duplicates. more...

(Submitter supplied) The epithelial-mesenchymal transition (EMT) is thought to be essential for cancer metastasis. While chromatin remodeling is involved in EMT, histone variants contribution in EMT remains poorly investigated. Recently, we showed that silencing or removal of the histone variant H2A.X induced mesenchymal-like characteristics, including activation of the EMT transcription factors, Slug and ZEB1, in human colon cancer cells. more...

(Submitter supplied) The newly identified claudin-low subtype of cancer is believed to represent the most primitive breast malignancies, having arisen from transformation of an early epithelial precursor with inherent stemness properties and metaplastic features. Challenging this hypothesis, we show both in vitro and in vivo that transcription factors inducing epithelial-mesenchymal transition can drive the development of claudin-low tumors from differentiated mammary epithelial cells, by playing a dual role in cell transformation and dedifferentiation.

(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...
