The TJ\u0027s integrity is maintained by a key protein–protein interaction between C-terminal motifs of claudins (CLDs) and the postsynaptic density 95 (PSD-95)/discs large/zonula occludens 1 (ZO-1; PDZ) domains of ZO-1. Weak but direct interaction of baicalin and its aglycon, baicalein—which are pharmacologically active components of Chinese skullcap (Radix scutellariae)—with ZO-1(PDZ1) have been observed in NMR experiments. Next, we observed TJ-mitigating activity of these flavonoids against Madin-Darby canine kidney (MDCK) II cells with the downregulation of subcellular localization of CLD-2 at TJs. Meanwhile, baicalein—but not baicalin—induced a slender morphological change of MDCK cells\u0027 shape from their normal cobblestone-like shapes. Since baicalin and baicalein did not induce a localization change of occludin (OCLN), a “partial” epithelial–mesenchymal transition (EMT) induced by these flavonoids was considered. SB431542, an ALK-5 inhibitor, reversed the CLD-2 downregulation of both baicalin and baicalein, while SB431542 did not reverse the slender morphology. In contrast, the MEK/ERK inhibitor U0126 reversed the slender shape change. Thus, in addition to inhibition of the ZO-1–CLD interaction, activation of both transforming growth factor-β (TGF-β) and MEK/ERK signaling pathways have been suggested to be involved in TJ reduction by these flavonoids. Finally, we demonstrated that baicalin enhanced the permeability of fluorescence-labeled insulin via the paracellular pathway of the Caco-2 cell layer. We propose that baicalin, baicalein, and Radix scutellariae extract are useful as drug absorption enhancers.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "ファイル公開：2021-11-15", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Elsevier", "subitem_publisher_language": "en"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1016/j.ejphar.2020.173436", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2020.
