Abstract

Lipolysis-stimulated lipoprotein receptor (LSR), a lipid metabolism-related factor localized in tricellular tight junctions (tTJs), plays an important role in maintaining the epithelial homeostasis. LSR is highly expressed in well-differentiated cancers, and its expression decreases during malignancy. The LSR antibody inhibits cell growth and promotes apoptosis in some cancers. Histone deacetylases (HDACs) are thought to play a crucial role in carcinogenesis, and HDAC inhibitors promote differentiation and prevent cell proliferation and migration in cancers. HDAC inhibitors together with TNFα also induce apoptosis via TNFα-related apoptosis-inducing ligand (TRAIL) in some cancers. In this study, we investigated the apoptosis signaling induced by an anti-LSR antibody in human salivary duct adenocarcinoma (SDC) cell line A253, compared to TRAIL-induced apoptosis. A253 cells were treated with human recombinant TNFα with or without HDAC inhibitor trichostatin A (TSA) and quisinostat (JNJ-26481585). Treatment using TNFα with HDAC inhibitors markedly induced apoptosis in A253 cells and the anti-TNFα antibody prevented the induced apoptosis. A253 cells were treated with an antibody against the extracellular N-terminal domain of human LSR (LSR-N-ab) with or without HDAC inhibitors. Treatment with HDAC inhibitors induced LSR expression in the membranes of A253 cells. Treatment using LSR-N-ab with HDAC inhibitors markedly promoted apoptosis in A253 cells. The tricellular signaling pathway JNK inhibitor SP600125 and Hippo pathway MST1/2 inhibitor XMU-MP-1 prevented the apoptosis induced by treatment using TNFα or LSR-N-ab with HDAC inhibitors. Our findings indicated that treatment with TNFα or LSR-N-ab with HDAC inhibitors might be useful in the therapy for human SDC by enhancing apoptosis.

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.
