  1. Suzuki K, Sentani K, Tanaka H, Yano T, Suzuki K, Oshima M, et al. Deficiency of Stomach-Type Claudin-18 in Mice Induces Gastric Tumor Formation Independent of H. Pylori Infection. Cell Mol Gastroenterol Hepatol. 2019;: pubmed publisher
  2. Tsukita S, Tanaka H, Tamura A. The Claudins: From Tight Junctions to Biological Systems. Trends Biochem Sci. 2019;44:141-152 pubmed publisher
    ..Meanwhile, ongoing studies at the cell and tissue levels are clarifying how the paracellular barrier and/or channel functions of claudin-based TJs, which are both robust and flexible, organize various biological systems. ..
  3. Yano T, Torisawa T, Oiwa K, Tsukita S. AMPK-dependent phosphorylation of cingulin reversibly regulates its binding to actin filaments and microtubules. Sci Rep. 2018;8:15550 pubmed publisher
    ..We propose that the cellular metabolic state, which involves AMPK, can contribute to the organization and maintenance of epithelial tissues through cingulin's tight junction/cytoskeleton regulation. ..
  4. Tanaka H, Imasato M, Yamazaki Y, Matsumoto K, Kunimoto K, Delpierre J, et al. Claudin-3 regulates bile canalicular paracellular barrier and cholesterol gallstone core formation in mice. J Hepatol. 2018;69:1308-1316 pubmed publisher
    ..Thus, altered phosphate ion metabolism under cholesterol overdose plays a major role in the lifestyle- and age-related risks of developing cholesterol gallstone disease. ..

    ..Furthermore, we revealed a relationship between macrophage recruitment and CLDN1 levels in human AD patients. Our findings collectively suggest that CLDN1 regulates the pathogenesis, severity, and natural course of human AD. ..

    ..We constructed a theoretical model, which indicated that the apical cytoskeleton, acting like a viscoelastic fluid, provides a self-organizing mechanism in tracheal MCCs to align BBs linearly for mucociliary transport. ..
