Epithelial-mesenchymal plasticity plays a critical role in many solid tumor types as mediator of metastatic dissemination and treatment resistance. In addition, there is also growing appreciation that the epithelial/mesenchymal status immune evasion suppression. A deeper understanding immunological features different has been facilitated by availability large gene expression datasets developmen...

Fos-related antigen 1 (Fra1) has been proposed as a gatekeeper of the mesenchymal-epithelial transition to epithelial-mesenchymal transition. Here, we showed that de-phosphorylated JNK2 increased the expression of Fra1 by promoting the expression of c-Jun and Jun-B. Conversely, phosphorylated JNK2 suppressed its expression via enhancing the ubiquitination of c-Jun and Jun-B. These data provided...

BACKGROUND Gastroesophageal reflux (GER) contributes to periprosthetic leakage after prosthetic voice rehabilitation. However, underlying mechanisms are unclear, and markers predicting anti-reflux therapy response are missing. METHODS We assessed epithelial-mesenchymal transition in 148 consecutive biopsies from 44 patients with/without fistula enlargement under dual-probe pH monitoring befor...

BACKGROUND The excess and persistent accumulation of fibroblasts due to aberrant tissue repair results in fibrotic diseases such as idiopathic pulmonary fibrosis. Recent reports have revealed significant changes in microRNAs during idiopathic pulmonary fibrosis and evidence in support of a role for microRNAs in myofibroblast differentiation and the epithelial-mesenchymal transition in the conte...

MUC1 is a transmembrane glycoprotein, apically expressed in most epithelial cells, used in the differential diagnosis of carcinomas and for discrimination of tumors of non-epithelial origin showing epithelioid features. Little attention has been paid so far though, on its possible significance in embryonic tissues. A preliminary study from our group revealed MUC1 expression in the cap mesenchym...

Background and Objective: Mesenchymal stem cells (MSCs) promote metastasis in colorectal cancer; however, the mechanism underlying this process is not fully understood. Epithelial to mesenchymal transition (EMT) is a key step in tumor acquisition of metastatic phenotype. We aimed to investigate the effect of MSCs on the expression of EMT markers, as well as cancer stem cell markers in HT-29 col...

Epithelial-to-mesenchymal transition (EMT) endows epithelial cells with enhanced motility and invasiveness, allowing them to participate in many physiological and pathological processes. Epithelial-to-mesenchymal transition contributes to the generation of circulating tumor cells (CTCs) in epithelial cancers because it increases tumor cell invasiveness, promotes tumor cell intravasation and ens...

Background The purpose of the present study was to evaluate relationship between chronic endometritis and epithelial-mesenchymal transition in endometrium infertile patients implantation phase. Methods Endometrial biopsy specimens from 66 infertility were analyzed. presence investigated by immunostaining for CD138. Immunohistochemical staining E-cadherin, N-cadherin, Slug, Snail performed, expr...

The skin is a composite structure composed of a superficial epidermis and an underlying dermis. Wounding of this structure with resultant functional and anatomical disintegration leads to a cascade of events directed at the restoration of these features. However, maintenance of anatomical integrity has a higher priority from the standpoint of preservation of homeostatic equilibrium. The uncoupl...
