(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) MiR-455-3p has been reported to suppress the expression of ROCK2, HOXB5, hTERT, and RUNX2, which are involved in multiple biological processes including renal fibrosis, chondrogenic development and differentiation, Alzheimer’s disease, preeclampsia, and tumorigenesis. Here, we showed that miR-455-3p broadly inhibited TGF-beta-induced EMT by repressing the expression of Smad2, ZEB1, and HDAC2 in breast cancer cells, and that miR-455-3p loss-of-function promotes the acquisition of cell invasive properties and the ability to metastasize. more...

(Submitter supplied) GATA3 is a basic and essential transcription factor that regulates many pathophysiological processes that is required for the development of mammary luminal epithelial cells. Loss-of-function GATA3 alterations in breast cancer are associated with poor prognosis. However, its regulation and function in miRNAs expression has been less explored.

(Submitter supplied) To elucidate the mechanisms by which the mir-200 and the miR-183~96~182 cluster could regulate EMT and thus cellular migration, invasion and metastasis in NSCLC, we searched for common predicted targets of these microRNA families that might have a potential role in these biological processes. First we performed a cross comparison of multiple gene expression datasets from our mouse models of metastasis. 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) 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. In this study, we investigated the expression of EMT-associated genes and microRNAs in primary colorectal cancer while considering intratumor heterogeneity. more...

(Submitter supplied) Epithelial ovarian cancer (EOC) is clinically heterogeneous, comprising different histological and biological subtypes. Multiple studies have implicated epithelial-mesenchymal transition (EMT), a biological process by which polarized epithelial cells convert into a mesenchymal phenotype, to contribute significantly to this molecular heterogeneity of EOC. From gene expression analyses of a collection of EMT-characterized EOC cell lines, we found that the expression of the transcription factor Grainyhead-like 2 (GRHL2) correlates with E-cadherin expression and the epithelial phenotype. 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) 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) The Zeb1 transcriptional repressor plays a key role in metastasis through the down-regulation of genes that are strong inducers of epithelial differentiation and inhibitors of stem-ness. Here we report that Zeb1 controls the expression of numerous oncogenic and tumor suppressive microRNAs (miRs). Zeb1 stimulated pro-migratory cytoskeletal processes by down-regulating miR-34a and activated Rho GTPases through Arhgap1, a Cdc42 GTPase activating protein and novel miR-34a target gene. more...

(Submitter supplied) ADCY9 encodes AC9, which is 1 of 9 transmembrane AC isoforms (AC1-9) that catalyze the synthesis of cyclic AMP from ATP and are regulated primarily by heterotrimeric G-protein-coupled receptors. We ectopically expressed AC9 in 393P cells and found that, relative to empty vector controls, the AC9 transfectants had higher cyclic AMP levels and were more migratory and invasive in Boyden chambers. We examined the prognostic value of an AC9-regulated gene expression signature derived from 393P_AC9 cells and 393P_vector cells. more...
