Epithelial-mesenchymal transition (EMT) in epithelial cells has been indicated as an important component of neoplastic transformation although, the genetic mechanism involved in this process has not been defined. The aim of this study was to evaluate the expression of different genes related to EMT such as E-cadherin, TGFbeta1, TGFbeta2, h-RAS, TWIST1, SNAIL2, SMAD5, FN1, CEACAM1 and JAG1 using...

BACKGROUND Bone morphogenetic protein 4 (BMP4) signaling is involved in the development of Barrett's esophagus (BE), a precursor of esophageal adenocarcinoma (EAC). In various cancers, BMP4 has been found to induce epithelial-mesenchymal transition (EMT) but its function in the development of EAC is currently unclear. AIM To investigate the expression of BMP4 and several members of the BMP4 p...

Recent studies have identified a critical role for lysophosphatidic acid (LPA) in the progression of ovarian cancer. Using a transcription factor activation reporter array, which analyzes 45 distinct transcription factors, it has been observed that LPA observed robustly activates the transcription factor hypoxia-induced factor-1α (HIF1α) in SKOV3.ip ovarian cancer cells. HIF1α showed 150-fold i...

Increasing evidence has demonstrated that aberrant expressions of long non-coding RNAs (lncRNAs) are involved in various malignancies, including hepatocellular carcinoma (HCC). This study aimed to investigate the role of lncRNA colon cancer-associated transcript 2 (CCAT2) in the progression of HCC. Quantitative real-time polymerase chain reaction analysis confirmed that CCAT2 was upregulated in...

Snail and Zeb transcription factors induce epithelial-to-mesenchymal transition (EMT) in embryonic and adult tissues by direct repression of E-cadherin transcription. The repression of E-cadherin transcription by the EMT inducers Snail1 and Zeb2 plays a fundamental role in defining embryonic territories in the mouse, as E-cadherin needs to be downregulated in the primitive streak and in the epi...
