A lysosomal enzyme referred to as N-acylethanolamine-hydrolyzing acid amidase (NAAA) catalyzes the same reaction with preference to palmitoylethanolamide, an endogenous analgesic and neuroprotective substance, and is therefore expected as a potential target of therapeutic drugs. In the in vitro assays thus far performed, the maximal activity of NAAA was achieved in the presence of both nonionic detergent (Triton X-100 or Nonidet P-40) and the SH reagent dithiothreitol. However, endogenous molecules that might substitute for these synthetic compounds remain poorly understood. Here, we examined stimulatory effects of endogenous phospholipids and thiol compounds on recombinant NAAA. Among different phospholipids tested, choline- or ethanolamine-containing phospholipids showed potent effects, and 1 mM phosphatidylcholine increased NAAA activity by 6.6-fold. Concerning endogenous thiol compounds, dihydrolipoic acid at 0.1–1 mM was the most active, causing 8.5–9.0-fold stimulation. These results suggest that endogenous phospholipids and dihydrolipoic acid may contribute in keeping NAAA active in lysosomes. Even in the presence of phosphatidylcholine and dihydrolipoic acid, however, the preferential hydrolysis of palmitoylethanolamide was unaltered. We also investigated a possible compensatory induction of NAAA mRNA in brain and other tissues of FAAH-deficient mice. However, NAAA expression levels in all the tissues examined were not significantly altered from those in wild-type mice.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第605号"}]},"item_10006_relation_15":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1021/cn300007s","subitem_relation_type_select":"DOI"}},{"subitem_relation_type":"hasVersion","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ncbi.nlm.nih.gov/pmc/articles/pmc3382453/","subitem_relation_type_select":"URI"}}]},"item_10006_relation_22":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"22860206","subitem_relation_type_select":"PMID"}}]},"item_10006_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 2012 American Chemical Society","subitem_rights_language":"en"}]},"item_10006_text_30":{"attribute_name":"KEID","attribute_value_mlt":[{"subitem_text_value":"27644"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Tai, Tatsuya","creatorNameLang":"en"},{"creatorName":"田井, 達也","creatorNameLang":"ja"},{"creatorName":"タイ, タツヤ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-10-28"}],"displaytype":"detail","filename":"Med_A605_abstract.pdf","filesize":[{"value":"89.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"内容の要旨","objectType":"abstract","url":"https://kagawa-u.repo.nii.ac.jp/record/237/files/Med_A605_abstract.pdf"},"version_id":"d3586a46-2ae1-4252-80a1-e839ad2ede08"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-10-28"}],"displaytype":"detail","filename":"Med_A605_result.pdf","filesize":[{"value":"82.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"審査の結果の要旨","objectType":"other","url":"https://kagawa-u.repo.nii.ac.jp/record/237/files/Med_A605_result.pdf"},"version_id":"148ae774-9743-42ca-a65c-6f9ef83cfa8b"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-10-28"}],"displaytype":"detail","filename":"Med_A605_summary.pdf","filesize":[{"value":"104.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文の要約","objectType":"summary","url":"https://kagawa-u.repo.nii.ac.jp/record/237/files/Med_A605_summary.pdf"},"version_id":"b5a06f07-3357-4d85-8c50-921df048e2d5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"N-Acylethanolamine-hydrolyzing acid amidase","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"NAAA","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"dihydrolipoic acid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fatty acid amide hydrolase","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"palmitoylethanolamide","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"phospholipid","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Endogenous molecules stimulating N-acylethanolamine-hydrolyzing acid amidase (NAAA)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Endogenous molecules stimulating N-acylethanolamine-hydrolyzing acid amidase (NAAA)","subitem_title_language":"en"}]},"item_type_id":"10006","owner":"11","path":["40"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-03-24"},"publish_date":"2015-03-24","publish_status":"0","recid":"237","relation_version_is_last":true,"title":["Endogenous molecules stimulating N-acylethanolamine-hydrolyzing acid amidase (NAAA)"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2024-02-07T08:45:30.030713+00:00"}
