Plasticity in epithelial tissues relates to processes of embryonic development, tissue fibrosis and cancer progression. Pharmacological modulation of epithelial transitions during disease progression may thus be clinically useful. Using human keratinocytes and a robotic high-content imaging platform, we screened for chemical compounds that reverse transforming growth factor β (TGF-β)-induced ep...
The direction of mesenchymal stem cell (MSC) differentiation is regulated by stimulation with various growth factors and cytokines. We recently established MSC lines, [transforming growth factor-β (TGF-β)-responsive SG‑2 cells, bone morphogenetic protein (BMP)-responsive SG‑3 cells, and TGF-β/BMP-non-responsive SG‑5 cells], derived from the bone marrow of green fluorescent protein-transgenic mi...
Transforming growth factor (TGF)-β1 is involved invasion of human trophoblasts. However, the underlying mechanisms remain unclear. In this study, we performed Transwell assay and found that TGF-β1 promoted the invasion of trophoblast cell line JEG-3. Treatment with TGF-β1 up-regulated the expression of receptor-regulated Smad transcription factors Smad2 and Smad3, and two invasive-associated ge...
Adenosine is a cellular metabolite with diverse derivatives that possesses wide range of physiological roles. We investigated the molecular mechanisms adenosine and cordycepin for their promoting effects in wound-healing process. The mitochondrial energy metabolism cell proliferation markers, cAMP responsive element binding protein 1 (CREB1) Ki67, were enhanced by cultured dermal fibroblasts. s...
Idiopathic pulmonary fibrosis (IPF) is a progressive, debilitating disease for which two medications, pirfenidone and nintedanib, have only recently been approved for treatment. The cytokine TGF-β has been shown to be a central mediator in the disease process. We investigated the role of a novel kinase, MAP3K19, upregulated in IPF tissue, in TGF-β-induced signal transduction and in bleomycin-in...
Hepatocellular carcinoma (HCC) occurs subsequent to liver injury, where regenerative hepatocytes develop into a dysplastic nodule and then early HCC, supporting the multistep hepatocarcinogenesis theory. Molecular alterations such as the p53 mutation, p16 gene silencing, and AKT signaling activation are found in the late stage of HCC progression. The overexpression of some marker molecules is o...
Transforming growth factor-β (TGF-β) is involved in vascular formation through activin receptor-like kinase (ALK)1 and ALK5. ALK5, which is expressed ubiquitously, phosphorylates Smad2 and Smad3, whereas endothelial cell (EC)-specific ALK1 activates Smad1 and Smad5. Because ALK5 kinase activity is required for ALK1 to transduce TGF-β signaling via Smad1/5 in ECs, ALK5 knockout (KO) mice were no...
The term epithelial to mesenchymal transition (eMT) designs the conversion of an epithelial cell in another cell with a fibro-blastic-like shape. Besides being essential for embryo morphogenesis, eMT also provides tumoral cells with higher invasion and greater resistance to apoptosis and is related to the initial stages of tumor metastasis. Among the many mesenchymal genes induced during eMT, s...
Transforming growth factor-β promotes aggressiveness and invasion of clear cell renal cell carcinoma
The molecular mechanisms whereby transforming growth factor-β (TGF-β) promotes clear cell renal cell carcinoma (ccRCC) progression is elusive. The cell membrane bound TGF-β type I receptor (ALK5), was recently found to undergo proteolytic cleavage in aggressive prostate cancer cells, resulting in liberation and subsequent nuclear translocation of its intracellular domain (ICD), suggesting that ...
Autosomal dominant polycystic kidney disease (ADPKD), characterized by the formation of numerous kidney cysts, is caused by PKD1 or PKD2 mutations and affects 0.1% of the population. Although recent clinical studies indicate that reduction of cAMP levels slows progression of PKD, this finding has not led to an established safe and effective therapy for patients, indicating the need to find new ...
