oral lichen planus (olp) is a chronic inflammatory disease of the oral mucosa which is considered by the world health organization (who) as a premalignant condition. one step in malignant development is so called epithelial mesenchymal transition (emt), a process whereby epithelial cells acquire mesenchymal characteristics. a factor known to induce emt is the transforming growth factor-β (tgf-β...

Chemical investigations of Aquimarina sp. MC085, which suppressed TGF-?-induced epithelial–mesenchymal transition (EMT) in A549 human lung cancer cells, led to the isolation compounds 1–3. Structural characterization using spectroscopic data analyses combination with Marfey’s analysis revealed that they were two diketopiperazines [cyclo(l-Pro-l-Leu) (1) and cyclo(l-Pro-l-Ile) (2)] one N-pheneth...

The transforming growth factor-beta superfamily is thought to be involved in the regulation and control of growth and differentiation. These growth factors signal through transmembrane serine/threonine kinase receptors. The activation of type I receptor kinase phosphorylates a family of intracellular signalling proteins called Smads. In the present study, we wanted to localize type I and type I...

Introduction: The aim of this study was to compare the protective effects of two types of aerobic and intermittent training on breast cancer as a result of TGFβ protein, Smad-3, and MMP2 gene in female mice. Methods: In the experimental study, a total of 24 female BALB/c mice after Tumorigenesis by MC4-L2 cell line in the three groups; Control, Aerobic, and Intermittent training groups,...

Gremlin is a developmental gene upregulated in human chronic kidney disease and in renal cells in response to transforming growth factor-β (TGF-β). Epithelial mesenchymal transition (EMT) is one process involved in renal fibrosis. In tubular epithelial cells we have recently described that Gremlin induces EMT and acts as a downstream TGF-β mediator. Our aim was to investigate whether Gremlin pa...

IL-23 p19/p40, produced by macrophages and dendritic cells, is critical for development of Th17 in several autoimmune diseases. In this study, bone marrow-derived (BMM) and splenic macrophages (SPM) from SJL/J mice, susceptible to autoimmune demyelinating disease following Theiler's virus (TMEV) infection, expressed IL-23 in response to TMEV. We identified potential binding sites for IFN respon...

BACKGROUND Helicobacter pylori elicited IL1B is one of the various modulators responsible for perturbation of acid secretion in gut. We have earlier reported that IL1B activated NFkB downregulates gastrin, a major modulator of acid secretion. However, we hypothesized that regulation of gastrin by IL1B would depend on the cell's ability to integrate inputs from multiple signaling pathways to gen...

Systems theory of Smad signalling Clarke et al 2 Abstract Transforming Growth Factor-β (TGFβ) signalling is an important regulator of cellular growth and differentiation. The principal intracellular mediators of TGFβ signalling are the Smad proteins, which upon TGFβ stimulation accumulate in the nucleus and regulate transcription of target genes. To investigate the mechanisms of Smad nuclear ac...
