The protumor function of UHRF1 is linked to both the Akt signaling cascade and the epithelial-mesenchymal transition in esophageal cancer

ABSTRACT: The epigenetic factor UHRF1 is highly expressed in many types of cancers, however, the underlying mechanism remains elusive. Here we report an oncogenic function of UHRF1 in esophageal cancer(EC). UHRF1 was observed to be robustly expressed in EC cells. Knockdown of UHRF1 was achieved in two EC cell lines TE-10 and Kyse410 using a shRNA-mediated lentivirus system. Silencing of UHRF1 led to the inhibition of the proliferation and the mesenchymal phenotype as determined by the wound-healing and the invasion-in-matrigel assays. Transcriptome profile analysis revealed that two groups of the genes are significantly suppressed upon the UHRF1-shRNA expression. One group is linked to Akt signal pathway and the other is linked to the epithelial-mesenchymal transition. MK2206, an Akt inhibitor, could also inhibit the growth and the mesenchymal phenotype of EC cells. But interestingly, while UHRF1 deficiency resulted in the downregulation of EMT-associated genes such as ZEB2, vimentin and twist1, MK2206 inhibition of Akt activity only suppressed the expression of snail, suggesting that the control of the mesenchymal phenotype by UHRF1 does not rely on the AKT cascade. We conclude that the oncogenic function of UHRF1 is linked to the synergistic effect on the Akt signal cascade and the EMT-specific genes in EC cells.

Selvaggio2020 - Microenvironment control of hybrid Epithelial-Mesenchymal phenotypes

Project description:Epithelial to Mesenchymal Transition (EMT) has been associated with cancer cell heterogeneity, plasticity and metastasis. It has been the subject of several modeling effort. This logical model of the EMT cellular network aims to assess microenvironmental signals controlling cancer-associated phenotypes amid the EMT continuum. Its outcomes relate to the qualitative degrees of cell adhesions by adherent junctions and focal adhesions, two features affected during EMT. Model attractors recover epithelial, mesenchymal and hybrid phenotypes, and simulations show that hybrid phenotypes may arise through independent molecular paths, involving stringent extrinsic signals. Of particular interest, model predictions and their experimental validations indicated that: 1) ECM stiffening is a prerequisite for cells overactivating FAK-SRC to upregulate SNAIL1 and acquire a mesenchymal phenotype, and 2) FAK-SRC inhibition of cell-cell contacts through the Receptor Protein Tyrosine Phosphates kappa leads to the acquisition of a full mesenchymal rather than a hybrid phenotype.

Gene expression profiles of p53 depleted human mammary epithelial cells with their Ras-infected epithelial and mesenchymal derivatives

Project description:The epithelial-mesenchymal transition (EMT) is an embryonic transdiffrentiation program which consists of the conversion of polarized epithelial cells into a motile mesenchymal phenotype. EMT is aberrantly reactivated during tumor progression, promoting metastatic dissemination. Herein, we demonstrate that EMT permissive conditions also favor tumor initiation by minimizing the number of events required for neoplastic transformation. We further demonstrated that even partial commitment of human mammary epithelial cells into an EMT program is sufficient to confer malignant properties, suggesting that the reactivation of embryonic EMT inducers participate to the primary tumor growth long before the initiation of the invasion-metastasis cascade. Human mammary epithelial cells (HMEC) were sequentially depleted in p53 through RNA interference (shp53), transduced with H-RasG12V and immortalized by hTert. Two different Tert/shp53/Ras cell population emerge that display either an epithelial (Epi) or a mesenchymal (Mes) phenotype. Gene expression profiles of the Tert/shp53 control cells and of tert/shp53/Ras/Epi and Tert/shp53/Ras/Mes were analyzed.

Regan2022 - Mechanosensitive EMT model

Project description:This file contains a 136-node modular Boolean network model of EMT triggered by biomechanical and growth signaling crosstalk, linked to a published network of epithelial contact inhibition, proliferation, and apoptosis (MODEL2006170001). This model reproduces the ability of the core EMT transcriptional network to maintain distinct epithelial, hybrid E/M and mesenchymal states, as well as EMT driven by mitogens such as EGF on stiff ECM. We also reproduce the observed lack of stepwise MET, in that our model's dynamics does not pass through the hybrid E/M state during MET. We show that in the absence of strong autocrine signals such as TGFβ (not included in this version), cells cannot maintain their mesenchymal state in the absence of mitogens, on softer matrices, or at high cell density.

AKT/mTOR/HER/PI3K family genes as predictors of pCR for early stage breast cancer patients treated with the AKT inhibitor MK2206 in the I-SPY 2 TRIAL (NCT01042379)

Project description:The AKT inhibitor MK2206 (M) was one of the experimental agents evaluated in I-SPY 2, a neoadjuvant platform trial for high risk, early stage breast cancer, and graduated in the HER2+, HR-, and HR-HER2+ signatures. Based on the hypotheses that since MK2206 is an enzymatic inhibitor of AKT, response to MK2206 may be predicted by the relative pre-treatment levels of AKT kinase substrates, in pre-defined analyses we assessed 10 genes in the HER-AKT-mTOR pathway to test their association with pCR (complete pathologic response) in the MK2206 arm, in both HER2+ and HER2- subsets. We also tested 9 genes genes previously associated with response to MK2206 in vitro and in the HER2+ metastatic setting, and performed exploratory association analyses using whole-transcriptome data to identify additional predictive signals outside the HER-AKT-mTOR pathway.
