BACKGROUND: MiR-646 has been reported to be aberrantly expressed in human cancers. However, the underlying molecular mechanisms of action of miR-646 in gastric cancer (GC) have not yet been investigated. METHODS: In vitro function of miR-646 in GC was evaluated using EdU assay, plate colony formation assay, and matrigel invasion assay. Real-time PCR or western blotting was performed to detect miR-646 and FOXK1 expressions. In vivo tumour growth and metastasis were conducted in nude mice...

Fibrosis is a chronic process involving development and progression of multiple diseases in various organs and is responsible for almost half of all known deaths. Epithelial-mesenchymal transition (EMT) is the vital process in organ fibrosis. Lens is an elegant biological tool to investigate the fibrosis process because of its unique biological properties. Using gain- and loss-of-function assays, and different lens fibrosis models, here we demonstrated that microRNA (miR)-26a and miR-26b, members of the miR-26 family have key roles in EMT and fibrosis...

Uterine carcinosarcomas (UCSs) are highly aggressive malignancies associated with poor prognoses and limited treatment options. These tumors are hypothesized to develop from the endometrial adenocarcinoma (EAC) through epithelial-mesenchymal transition (EMT). We test this long-standing hypothesis by depleting miR-200, a family of microRNAs critical for EMT, in EAC cell lines. Our data suggest that UCSs do not develop from EACs via EMT. Clinically more relevant, we show that miR-200 expression in UCS cells induces a robust mesenchymal-epithelial transition (MET)...

Hepatocellular carcinoma (HCC) is one of the most common cancers in the world, and represents the second most frequently cancer and third most common cause of death from cancer worldwide. At advanced stage, HCC is a highly aggressive tumor with a poor prognosis and with very limited response to common therapies. Therefore, there is still the need for new effective and well-tolerated therapeutic strategies. Molecular-targeted therapies hold promise for HCC treatment. One promising molecular target is the multifunctional serine/threonine kinase glycogen synthase kinase 3 (GSK-3)...

Ormeloxifene (ORM), is a clinically approved selective estrogen receptor modulator, which has also shown excellent anti-cancer activity, thus it can be an ideal repurposing pharmacophore. Herein, we report therapeutic effects of ORM on prostate cancer (PrCa) and elucidate a novel molecular mechanism of its anti-cancer activity. ORM treatment inhibited epithelial to mesenchymal transition (EMT) process as evident by repression of N-cadherin, Slug, Snail, and vimentin, MMPs (MMP2 and MMP3), β-catenin/TCF-4 transcriptional activity, and induced the expression of pGSK3β...

In many cancer types, integrin-mediated signaling regulates proliferation, survival and invasion of tumorigenic cells. However, it is still unclear how integrins crosstalk with oncogenes to regulate tumorigenesis and metastasis. Here we show that oncogenic K-Ras(V12) upregulates α6-integrin expression in Madin-Darby canine kidney (MDCK) cells via activation of the mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK)/Fos-related antigen 1-signaling cascade. Activated α6-integrins promoted metastatic capacity and anoikis resistance, and led to perturbed growth of MDCK cysts...

Akt1 is essential for the oncogenic transformation and tumor growth in various cancers. However, the precise role of Akt1 in advanced cancers is conflicting. Using a neuroendocrine TRansgenic Adenocarcinoma of the Mouse Prostate (TRAMP) model, we first show that the genetic ablation or pharmacological inhibition of Akt1 in mice blunts oncogenic transformation and prostate cancer (PCa) growth. Intriguingly, triciribine (TCBN)-mediated Akt inhibition in 25-week old, tumor-bearing TRAMP mice and Akt1 gene silencing in aggressive PCa cells enhanced epithelial to mesenchymal transition (EMT) and promoted metastasis to the lungs...

Chemotherapy for pancreatic cancer has diversified following the addition of more treatment regimens; however, in spite of this, pancreatic cancer remains a fatal disease. Preoperative (neoadjuvant) chemotherapy (NAC) or neoadjuvant chemoradiation therapy (NACRT) has been developed and implemented. For patients with borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC), a number of clinical trials have been conducted; NACRT was demonstrated to improve resectability, R0 resection rate, overall survival rate, disease-free survival rate and even an LAPC and BRPC survival advantage over NAC...

Recent advances in tumor metabolism have revealed that metabolic reprogramming could dramatically promote caner metastasis. However, the relation and mechanism between metastasis and metabolic reprogramming are not thoroughly explored. Cell proliferation, colony formation, and invasion analysis were performed to evaluate the role of FAM210B in human cancer cells. Human ovarian cancer xenograft model was used to determine the effects of inhibiting FAM210B by shRNA on tumor metastasis. Microarray analysis was used to determine the target genes of FAM210B...

BACKGROUND: Accumulating evidence indicates that N-cadherin is a cell adhesion molecule that has critical roles in tumour progression. However, the role of N-cadherin in hepatocellular carcinoma (HCC) remains controversial. METHODS: This study aims to investigate the expression status of N-cadherin and its molecular mechanisms in HCC. RESULTS: The expression of N-cadherin was markedly overexpressed in HCC tissues and cell lines. We identified that miR-199b-5p binds to the 3'-UTR of N-cadherin mRNA, thus decreasing N-cadherin expression in HCC cells...

Diabetic nephropathy (DN) is among the most severe complications of diabetes mellitus, and may lead to end-stage renal disease. Sustained exposure to advanced glycation end products (AGEs) typically causes renal tubular epithelial cells (TECs) to suffer from an epithelial-to-mesenchymal transition (EMT). However, there remains no consensus regarding the mechanism underlying the cause of EMT in TECs as induced by AGEs. In the present study, we investigated the promotion of EMT in TECs by AGEs, and the activation of Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling...

Widespread genome hypo-methylation and promoter hyper-methylation of epithelium-specific genes are hallmarks of stable epithelial-to-mesenchymal transition (EMT), which in prostate cancer (PCa) correlates with castration resistance, cancer stem cells generation, chemoresistance and worst prognosis. Exploiting our consolidated 'ex-vivo' system, we show that cancer-associated fibroblasts (CAFs) released factors have pivotal roles in inducing genome methylation changes required for EMT and stemness in EMT-prone PCa cells...

Gastric cancer (GC) represents the fourth most common malignant neoplasm and the second leading cause of cancer death. Despite therapeutic advances in recent decades, the clinical outcome remains dismal owing to the fact that most GC patients show advanced disease at diagnosis and current chemotherapy only confers a modest survival advantage. Identification of key molecular signaling pathways involved in gastric carcinogenesis and progression would aid in early diagnosis and provide a rational design for targeted therapies in selected patients with advanced GC, to improve their outcome...

MicroRNAs, a group of posttranscriptional regulators of numerous genes, are active participators during the development and progression of ovarian cancer (OC). This study confirmed for the first time that miR-216a was gradually increased in normal, benign, borderline, and OC tissues and that its expression was significantly upregulated in all OC cell lines. Analysis of its clinical association demonstrated that elevated expression of miR-216a was associated with lymph node metastasis and advanced FIGO stage and was correlated with the poor survival of OC patients...

Chemokine (CC motif) ligand 18 (CCL18) is involved in the remodeling of tumor microenvironment and have critical roles in oncogenesis, invasiveness and metastasis. We previously investigated that CCL18 was overexpressed in primary oral squamous cell carcinoma (OSCC) tissues and associated with advanced clinical stage of OSCC patients. However, the underlying mechanisms of this CCL18-derived activity remains unidentified. This study showed exogenous CCL18 increased cell migration, invasion and induced cell epithelial-to-mesenchymal transition (EMT), displaying that E-cadherin, an epithelial marker, decreased and N-cadherin, a mesenchymal marker, increased, compared to negative control in OSCC cells...

BACKGROUND: Glioblastoma is the most common and most lethal primary brain cancer. CBF1 (also known as Recombination signal Binding Protein for immunoglobulin kappa J, RBPJ) is the cardinal transcriptional regulator of the Notch signalling network and has been shown to promote cancer stem-like cells (CSCs) in glioblastoma. Recent studies suggest that some of the malignant properties of CSCs are mediated through the activation of pro-invasive programme of epithelial-to-mesenchymal transition (EMT)...

We aimed to investigate the association of the expression levels of five epithelial-mesenchymal transition (EMT)-related proteins (Snail, Twist, E-cadherin, N-cadherin, and Vimentin) with tumorigenesis, pathologic parameters and prognosis in tongue squamous cell carcinoma (TSCC) patients by immunohistochemistry of tissue microarray. The expression levels of Snail, E-cadherin, N-cadherin and Vimentin were significantly different between the tumor adjacent normal and tumor tissues. In tumor tissues, lower E-cadherin and higher N-cadherin levels were associated with a higher grade of cell differentiation, advanced stage of disease, and lymph node metastasis...
