Abstract
It is known that there are abnormalities of tight junction functions, cell migration and mitochondrial metabolism in human endometriosis and endometrial carcinoma. In this study, we investigated the effects of growth factors and their inhibitors on the epithelial permeability barrier, cell migration and mitochondrial metabolism in 2D and 2.5D cultures of human endometrioid endometrial carcinoma Sawano cells. We also investigated the changes of bicellular and tricellular tight junction molecules and ciliogenesis induced by these inhibitors. The growth factors TGF-β and EGF affected the epithelial permeability barrier, cell migration and expression of bicellular and tricellular tight junction molecules in 2D and 2.5D cultures of Sawano cells. EW-7197 (a TGF-β receptor inhibitor), AG1478 (an EGFR inhibitor) and SP600125 (a JNK inhibitor) affected the epithelial permeability barrier, cell migration and mitochondrial metabolism and prevented the changes induced by TGF-β and EGF in 2D and 2.5D cultures. EW-7197 and AG1478 induced ciliogenesis in 2.5D cultures. In conclusion, TGF-β and EGF promoted the malignancy of endometrial cancer via interplay among the epithelial permeability barrier, cell migration and mitochondrial metabolism. EW-7197 and AG1478 may be useful as novel therapeutic treatments options for endometrial cancer.
期刊介绍：
Tissue Barriers is the first international interdisciplinary journal that focuses on the architecture, biological roles and regulation of tissue barriers and intercellular junctions. We publish high quality peer-reviewed articles that cover a wide range of topics including structure and functions of the diverse and complex tissue barriers that occur across tissue and cell types, including the molecular composition and dynamics of polarized cell junctions and cell-cell interactions during normal homeostasis, injury and disease state. Tissue barrier formation in regenerative medicine and restoration of tissue and organ function is also of interest. Tissue Barriers publishes several categories of articles including: Original Research Papers, Short Communications, Technical Papers, Reviews, Perspectives and Commentaries, Hypothesis and Meeting Reports. Reviews and Perspectives/Commentaries will typically be invited. We also anticipate to publish special issues that are devoted to rapidly developing or controversial areas of research. Suggestions for topics are welcome. Tissue Barriers objectives: Promote interdisciplinary awareness and collaboration between researchers working with epithelial, epidermal and endothelial barriers and to build a broad and cohesive worldwide community of scientists interesting in this exciting field. Comprehend the enormous complexity of tissue barriers and map cross-talks and interactions between their different cellular and non-cellular components. Highlight the roles of tissue barrier dysfunctions in human diseases. Promote understanding and strategies for restoration of tissue barrier formation and function in regenerative medicine. Accelerate a search for pharmacological enhancers of tissue barriers as potential therapeutic agents. Understand and optimize drug delivery across epithelial and endothelial barriers.
