(Submitter supplied) Cancer cells simultaneously featuring epithelial and mesenchymal traits appear particularly competent to invade and metastasize. However, genetic prerequisites and signaling pathways promoting such partial epithelial-to-mesenchymal transitions (EMT) remain obscure. Here we report that murine intestinal organoids with hyperactive Wnt and MAPK signaling, and mutant Trp53 are purely epithelial and non-invasive in vitro, but initiate a collective invasion program when treated with TGFβ1. more...

(Submitter supplied) Colorectal cancer (CRC) is the third most common cancer worldwide. Recent studies pinpointed TIMELESS (TIM) to be crucially involved in replication protection/genomic stability, DNA damage response (DDR) and coordination of mitotic kinase activation with DNA replication termination. Here we present the first direct evidence of a TIM-ZEB1 axis which control key pathological processes in CRC. We found that loss of TIM expression unleashes ZEB1 which triggers epithelial-to-mesenchymal transition program, cell migration/invasion increase and acquirement of stem-like phenotype of CRC cells. more...

(Submitter supplied) Using an in vitro model for malignant transformation of human bronchial epithelial cells (HBECs) we have found epithelial-to-mesenchymal transition (EMT) and expression of the EMT-transcription factor ZEB1 are early and critical events. Specifically, we found preexisting oncogenic mutations in TP53 and KRAS were required for HBECs to engage EMT machinery in response to microenvironmental (serum/TGFβ) or specific oncogenetic (MYC) EMT-inducing factors, which induce EMT through distinct TGFβ-dependent and vitamin D receptor (VDR)-dependent pathways, respectively, with both requiring ZEB1. more...

(Submitter supplied) Cell plasticity is emerging as a key regulator of tumor progression and metastasis. During carcinoma dissemination epithelial cells undergo epithelial to mesenchymal transition (EMT) processes characterized by the acquisition of migratory/invasive properties, while the reverse, mesenchymal to epithelial transition (MET) process, is also essential for metastasis outgrowth. Different transcription factors, called EMT-TFs, including Snail, bHLH and Zeb families are drivers of the EMT branch of epithelial plasticity, and can be post-transcriptionally downregulated by several miRNAs, as the miR-200 family. more...

(Submitter supplied) We investigated the effect of miR-1199-5p, miR-200b-3p and miR-429-3p on gene expression profiles during TGFbeta-induced EMT in normal murine mammary gland cells by using the mRNA-sequencing. Our analysis demonstrates that miR-1199-5p and both miR-200 family members share only 6 target genes, indicating that besides regulating Zeb1 expression they exert distinct functions during EMT.

(Submitter supplied) The transcription factor SNAIL1 is a master regulator of epithelial-to-mesenchymal transition, a process entailing massive gene expression changes. To better understand SNAIL1-induced transcriptional reprogramming we performed time-resolved transcriptome analysis upon conditional SNAIL1 expression in colorectal cancer cells. Bioinformatic analyses indicated that SNAIL1 strongly affected Wnt/β-Catenin pathway activity. more...

(Submitter supplied) Purpose: Environmentally induced diseases, including cancer typically develop long after the exposure has occurred. However, most of the toxicological studies are conducted during active exposure. Therefore, environmental exposure-induced adverse effects that persist after cessation of exposure is poorly understood. Methods: Immortalized human bronchial epithelial cells (BEAS-2B) were cultured in Dulbecco’s Modified Eagle’s Medium (DMEM, Cellgro) supplemented with 1% Penicillin Streptomycin and 10% Fetal Bovine Serum (FBS, Atlanta Biologicals) at 37 degree C and 5 % CO2. more...

(Submitter supplied) Epithelial-mesenchymal transition (EMT) fosters cancer cell invasion and metastasis, the main cause of cancer-related mortality. Growing evidence that SNAIL and ZEB transcription factors, typically portrayed as master regulators of EMT, may be dispensable for this process, led us to re-investigate its mechanistic underpinnings. For this, we used an unbiased computational ap-proach that integrated time-resolved analyses of chromatin structure and differential gene ex-pression, to predict transcriptional regulators of TGFβ1-inducible EMT in the MCF10A mam-mary epithelial cell line model. more...

(Submitter supplied) Although epithelial-mesenchymal transition (EMT) has been implicated as the pivotal event in metastasis, there is insufficient evidence related to EMT in clinical settings. Intratumor heterogeneity may lead to underestimation of gene expression representing EMT.

(Submitter supplied) At the molecular level, epithelial-to-mesenchymal transition (EMT) necessitates extensive transcriptional reprogramming which is orchestrated by a small group of gene regulatory proteins. The transcription factor SNAIL1 is a zinc-finger DNA-binding protein and well-known master regulator of EMT. However, knowledge of its immediate target genes is incomplete. Here, we performed ChIP-seq to chart genome-wide SNAIL1 chromosomal binding sites and to identify genes directly regulated by SNAIL1. more...
