Ursolic acid (UA) has various pharmacological\u00a0properties, such as antioxidant, anti\u2010inflammatory and anti- cancer. However, the effect of UA on TSLP regulation has not been fully elucidated. The aim of the present study was to analyze how UA regulates the production of TSLP in the human mast cell line HMc-1. Enzyme-linked immunosorbent assay, quantitative polymerase chain reaction analysis, western blotting, caspase-1 assay and fluorescent measurements of intracellular calcium levels were conducted to analyze the regulatory effects of UA. The results revealed that UA inhib- ited TSLP production and mRNA expression. In addition, UA reduced the activation of nuclear factor-\u03baB and degradation of I\u03baB\u03b1. caspase-1 activity was increased by exposure to phorbol myristate acetate plus calcium ionophore, whereas it was reduced by UA. Finally, UA treatment prevented an increase in intracellular calcium levels. These results indicated that UA may be a useful agent for the treatment and\/or prevention of\u00a0atopic and inflammatory diseases, and its effects are likely\u00a0mediated by TSLP downregulation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ursolic acid downregulates thymic stromal lymphopoietin through the blockade of intracellular calcium\/caspase\u20101\/NF\u2010\u03baB signaling cascade in HMC\u20101 cells PHIL-DONG MOON1,2*, NA-RA HAN1*, JIN SOO LEE1, HYUNG-MIN KIM1\u00a0and HYUN-JA JEONG3 1department of Pharmacology, college of Korean Medicine,&nbsp;2center for converging Humanities, Kyung Hee University, Seoul 02447;&nbsp;3department of Food Science and Technology and Research Institute for Basic Science, Hoseo [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/misterx95.myds.me\/wordpress\/index.php?rest_route=\/wp\/v2\/posts\/2697"}],"collection":[{"href":"https:\/\/misterx95.myds.me\/wordpress\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/misterx95.myds.me\/wordpress\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/misterx95.myds.me\/wordpress\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/misterx95.myds.me\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=2697"}],"version-history":[{"count":1,"href":"https:\/\/misterx95.myds.me\/wordpress\/index.php?rest_route=\/wp\/v2\/posts\/2697\/revisions"}],"predecessor-version":[{"id":2699,"href":"https:\/\/misterx95.myds.me\/wordpress\/index.php?rest_route=\/wp\/v2\/posts\/2697\/revisions\/2699"}],"wp:attachment":[{"href":"https:\/\/misterx95.myds.me\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=2697"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/misterx95.myds.me\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=2697"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/misterx95.myds.me\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=2697"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
