Colorectal cancer (CRC) is the most common malignant disease worldwide due to its metastasis via the epithelial-mesenchymal transition (EMT) process. E-cadherin and Wnt signaling are emerging as potential targets for suppressing the EMT. In this context, Axin2 has been recognized as a negative regulator that inhibits glycogen synthase kinase 3β (GSK3β)-mediated degradation of Snail1, a transcriptional repressor of E-cadherin. However, Axin2 can also impede Wnt signaling via β-catenin degradation. Therefore, Axin2 may serve as either a promoter or suppressor of tumors, and the effects of its inhibition on the cell proliferation and metastasis of CRC require further elucidation...

Renal fibrosis is recognized as the common route of all chronic kidney disease (CKD) progressing to end-stage renal disease (ESRD). Additionally, accumulating evidence suggests that epithelial-mesenchymal transition (EMT) plays a significant role in the process of renal fibrogenesis. Liraglutide is a long-acting glucagon-like peptide-1 (GLP-1) analog that has been widely used to treat type 2 diabetes. Recent studies have demonstrated that the GLP-1 analogs could also exert protective effects in cardiac fibrosis models...

Emerging evidence has shown that the PIM serine/threonine kinase family, including PIM1, PIM2 and PIM3, is associated with tumour progression towards metastasis. PIM1, an attractive molecular target, has been identified as a potential prognostic biomarker for haematological and epithelial malignancies. However, to date, the potential regulatory roles and molecular mechanisms by which PIM1 affects the development and progression of cancers, including clear-cell renal-cell carcinoma (ccRCC), remain largely unknown...

Clear cell renal cell carcinoma (ccRCC) is the most common and aggressive subtype of renal cancer. STAT3 pathway is altered in these tumors and p-STAT3 Ser727 is an independent prognostic factor for ccRCC. Protein kinase CK2 is altered in different types of tumors and overexpression of CK2α is considered predictive of bad prognosis and metastatic risk. CK2 subunits analyses in ccRCC samples showed increased CK2α/α' nuclear content in all cases, but decreased cytosolic CK2β (CK2βcyt) levels in the more advanced tumors...

Human cleft lip with or without cleft palate (CL/P) is a common craniofacial abnormality caused by impaired fusion of the facial prominences. We have previously reported that in the mouse embryo epithelial apoptosis mediates fusion at the seam where the prominences coalesce. Here, we show that apoptosis alone is not sufficient to remove the epithelial layers. We observed morphological changes in the seam epithelia, intermingling of cells of epithelial descent into the mesenchyme, and molecular signatures of Epithelial-Mesenchymal-Transition (EMT)...

Epithelial-mesenchymal transition (EMT) has been shown to associate with cancer stem cells and radioresistance. However, it is obscure whether EMT itself or specific EMT regulators play causal roles in these properties of salivary adenoid cystic carcinoma (SACC). Here, we exhibited that overexpression of HSP27 drove the migration and invasion, induced EMT, as well as mediated TGF-β1-induced EMT in SACC cells, accompanying the up-regulation of Snail1 and Prrx1. Conversely, HSP27 silencing reduced the migration and invasion and contributed to MET of SACC cells...

BACKGROUND: We investigated the effect of arsenic trioxide (ATO) for inhibition of signal transducer and activator of transcription 3 (STAT3) and epithelial-mesenchymal transition (EMT) in gastric cancer cells, and the role of SH2 domain-containing phosphatase-1 (SHP-1) during this process. METHODS: We used AGS cells, which showed minimal SHP-1 expression and constitutive STAT3 expression. After treatment of ATO, cellular migration and invasion were assessed by using wound closure assay, Matrigel invasion assay and 3-D culture invasion assay...

The FGFR4-388Arg variant has been related to poor prognosis in several types of cancer, including lung cancer. The mechanism underlying this association has not been addressed in detail in patients with this pathology. Here, we report that this FGFR4 variant induces MAPK and STAT3 activation and causes pro-oncogenic effects in NSCLC in vitro and in vivo. This variant induces the expression of EMT-related genes, such as N-cadherin, vimentin, Snail1 and Twist1. Indeed, the induction of N-cadherin protein expression by this variant is essential for its pro-tumorigenic role...

Resistance to anoikis and growth in anchorage-independent conditions are hallmarks of highly metastatic cancer cells. Anoikis is a type of apoptosis induced by inadequate cell/extracellular matrix (ECM) attachment and an attractive anti-cancer therapeutic strategy in cancer chemotherapeutic field. Therefore, the development of anoikis-inducing agents is useful and promising to overcome cancer. When FPDHP, a novel anoikis-inducing agent, was treated within 3h, FPDHP induced massive cell detachment in various human cancer cells, irrespective of apoptosis...

Melanoma is a malignant tumor derived from melanocytes. Once disseminated, it is usually highly resistant to chemotherapy and is associated with poor prognosis. We have recently reported that T-type calcium channels (TTCCs) are overexpressed in melanoma cells and play an important role in melanoma progression. Importantly, TTCC pharmacological blockers reduce proliferation and deregulate autophagy leading to apoptosis. Here, we analyze the role of autophagy during migration/invasion of melanoma cells. TTCC Cav3...

Lung cancer has a high propensity for metastasis. Cancer-associated fibroblasts (CAFs) are the main type of stromal cells in cancer tissue, are activated by tumor cells, and play a significant role in tumor development. However, whether CAFs induce lung cancer cell metastasis, as well as pathway involved in CAF-induced lung cancer cell metastasis, is uncertain. Snail1 is a transcriptional factor whose expression in the stroma is associated with lower survival rates in patients with cancer. However, how Snail1 regulates the crosstalk between stromal cells and tumor cells when it is expressed in the stroma has not been determined...

Pancreatic cancer (PDAC) is one of the most dismal of human malignancies. Inhibiting or delaying the progression of precursor lesions of PDAC, pancreatic intraepthial neoplasia (PanINs), to invasive cancer, would be a major step. In the present study, we used a transgenic murine model of pancreatic cancer to evaluate the impact of a conditional knockout of the transcription factor Snail1, a major factor in epithelial-to-mesenchymal transition, on acinar-to-ductal formation and on PanIN progression. By interbreeding conditional LsL-Snail floxf/wt ; LsL-Kras G12D and Pdx1-Cre strains, we obtained LsL-Kras G12D ;Pdx1-Cre(KP) mice, Snail1 heterozygous knockout LsL-Kras G12D ; LsL-Snail flox/- ;Pdx1-Cre(KPShet) mice or Snail1 homozygous knockout LsL-Kras G12D ;LsL-Snail flox/flox ;Pdx1-Cre(KPS) mice...

Ginsenoside 20(S)-Rh2 (GRh2) is a bioactive compound derived from ginseng that is believed to maintain health in traditional Chinese medicine. Emerging evidence has suggested that GRh2 exhibits anti‑cancer activity. The present study hypothesized that GRh2 has an anti‑cancer function in human cervical cancer cells. An MTS assay demonstrated that GRh2 attenuated proliferation of HeLa cells in a dose‑ and time‑dependent manner. In addition, GRh2 inhibited migration and invasion, as determined by wound healing and transwell invasion assays, respectively...

Metastasis and recurrence contribute to poor prognosis of hepatocellular carcinoma (HCC). Recently, we reported that interferon-α (IFN-α) can suppress metastasis of HCC; however, the underlying mechanism has not been fully described. In this study, we demonstrated that expression of dihydropyrimidine dehydrogenase (DPYD), a pyrimidine catabolic enzyme, was dose-dependently downregulated by IFN-α in HCC tissues from nude mice. Notably, DPYD expression was found to be significantly increased in HCC cell lines with higher metastatic potentials compared with their controls...

The aim of this study was to investigate the effect of Curcumae Rhizoma-Sparganii Rhizoma (CR-SR) medicated serum on the changes of epithelial-mesenchymal transition (EMT) in the triple-negative breast cancer (TNBC). The EMT model was developed by using the TNBC MDA-MB-468 cells, which were treated with TGF-β1. The migration and invasion abilities of TGF-β1-treated MDA-MB-468 cells were detected by wound healing assay and transwell assay. Protein expression levels of E-cadherin and vimentin were determined by western blot...

This study was aimed to figure out the association of single-nucleotide polymorphisms (SNPs) within miR-30a and its downstream molecules (i.e., Notch1, Snail1, p53, CD73, and TET1) with susceptibility to and prognosis of nephrotic syndrome (NS). In the aggregate, 265 patients and 281 healthy controls were gathered, and related laboratory indicators were examined. The miR-30a, Notch1, Snail1, TET1, p53, and CD73 expressions were also evaluated by quantitative real-time polymerase chain reaction (qRT-PCR), immunohistochemistry, or enzyme-linked immunosorbent assay...

The mesenchymal gene program has been shown to promote the metastatic progression of ovarian cancer; however, specific proteins induced by this program that lead to these metastatic behaviors have not been identified. Using patient derived tumor cells and established human ovarian tumor cell lines, we find that the Epithelial-to-Mesenchymal Transition inducing factor TWIST1 drives expression of discoidin domain receptor 2 (DDR2), a receptor tyrosine kinase (RTK) that recognizes fibrillar collagen as ligand...

CYLD lysine 63 deubiquitinase (CYLD) was originally identified as a tumor suppressor that is mutated in familial cylindromatosis. Unlike in cylindromatosis, downregulation of the deubiquitinase CYLD in melanoma, a highly aggressive tumor, is not caused by mutations in the CYLD gene, but rather by a constitutive and high expression of the snail family transcriptional repressor 1 (SNAIL1). A reduced CYLD level leads to B-cell lymphoma-3/p50/p52-dependent nuclear factor-κB activation, which in turn triggers the expression of genes such as cyclin D1 and N-cadherin...

It has been reported that the epithelial-mesenchymal transition (EMT) plays an important role in hepatocellular carcinoma (HCC). However, the relationship between the insulin-like growth factor-1 (IGF-1) and EMT of HCC was not fully elucidated. In the present work, we found that the expression of N-cadherin, Vimentin, Snail1, Snail2, and Twist1 was positively associated with IGF-1R expression, while E-cadherin expression was negatively associated with IGF-1 expression in human HCC samples. Furthermore, we observed that IGF-1 up-regulated the expression of N-cadherin, Vimentin, Snail1, Snail2 and Twist1, and down-regulated the expression of E-cadherin...
