During development, cardiac and skeletal muscle share major transcription factors and sarcomere proteins which were generally regarded as specific to either cardiac or skeletal muscle but not both in terminally differentiated adult cardiac or skeletal muscle. Here, we investigated whether artificial muscle constructed from human skeletal muscle derived stem cells (MDSCs) recapitulates developme...

Dysregulated epithelial to mesenchymal transition (EMT) in cancer cells endows invasive and metastatic properties upon cancer cells that favor successful colonization of distal target organs and therefore play a critical role in transforming early-stage carcinomas into invasive malignancies. EMT has also been associated with tumor recurrence and drug resistance and cancer stem cell initiation. ...

BACKGROUND Epithelial-mesenchymal transition (EMT) plays a crucial role in small airway fibrosis of patients with chronic obstructive pulmonary disease (COPD). Increasing evidence suggests that the urokinase plasminogen activator receptor (uPAR) is involved in the pathogenesis of COPD. Increased uPAR expression has been implicated in the promotion of EMT in numerous cancers; however the role of...

A growing body of evidence indicates that epithelial-mesenchymal transition (EMT) of human peritoneal mesothelial cells (HPMC) may play an important role in the development and progression of peritoneal fibrosis during long-term peritoneal dialysis (PD) leading to failure of peritoneal membrane function. Here, we review our own observations and those of others on the mechanisms of EMT of HPMC a...

BACKGROUND AND OBJECTIVES The clinical relevance of epithelial to mesenchymal transition (EMT) in hepatocellular carcinoma (HCC) progression has been highlighted during the last decade. The zinc finger E-box binding homeobox (ZEB) family, the zinc-finger transcriptional repressor (SNAI) family, and the basic helix-loop-helix transcription factor (Twist) family, known as the prominent EMT-induci...

We studied the mode of action of the low molecular weight heparin PK10169 and two of its constituent fractions: EMT 966 High Molecular Weight Fraction and EMT 967 Low Molecular Weight Fraction. EMT 966 like standard heparin, acts primarily on thrombin formed and not on prothrombinase (S type heparin). In contrast EMT 967 has no direct effect on thrombin. At high concentrations, it inhibits the ...

Epithelial-mesenchymal transition (EMT) plays a critical role in the development of tumor metastases by enhancing migration/invasion. One of the hallmarks of EMT is loss of E-cadherin and gain of N-cadherin expression, which are regulated by the core EMT-inducing transcription factors (EMT-TFs), such as Zeb1/2, Snai1/2 and Twist1. Here, we find that EMT-TFs can be dynamically degraded by an aty...

As a critical process during embryonic development, cancer progression and cell fate conversions, epithelial-mesenchymal transition (EMT) has been extensively studied over the last several decades. To further understand the nature of EMT, we performed meta-analysis of multiple microarray datasets to identify the related generic signature. In this study, 24 human and 17 mouse microarray datasets...

Mature tubular epithelial cells in adult kidney can undergo epithelial-to-mesenchymal transition (EMT), a phenotypic conversion that is fundamentally linked to the pathogenesis of renal interstitial fibrosis. Emerging evidence indicates that a large proportion of interstitial fibroblasts are actually originated from tubular epithelial cells via EMT in diseased kidney. Moreover, selective blocka...

Epithelial-to-mesenchymal transition (EMT) has been shown to play an important role in renal fibrogenesis. Recent studies suggested parathyroid hormone (PTH) could accelerate EMT and subsequent organ fibrosis. However, the precise molecular mechanisms underlying PTH-induced EMT remain unknown. The present study was to investigate whether Wnt/β-catenin signaling pathway is involved in PTH-induce...
