Diacylglycerol kinase (DGK) converts DAG to phosphatidic acid and acts as an endogenous regulator of PKC activity. Akt/PKB is associated with a downstream insulin signaling, and PKCbeta attenuates insulin-stimulated Akt phosphorylation. METHODS AND RESULTS: We examined transgenic mice with cardiac-specific overexpression of DGKzeta (DGKzeta-TG) compared to wild type (WT) mice in streptozotocin-induced (STZ, 150 mg/kg) diabetic and nondiabetic conditions. After 8 weeks, decreases in heart weight and heart weight/body weight ratio in diabetic WT mice were inhibited in DGKzeta-TG mice. Echocardiography at 8 weeks after STZ-injection demonstrated that decreases in left ventricular end-diastolic diameter and fractional shortening observed in WT mice were attenuated in DGKzeta-TG mice. Thinning of the interventricular septum and the posterior wall in diabetic WT hearts were blocked in DGKzeta-TG mice. Reduction of transverse diameter of cardiomyocytes isolated from the left ventricle in diabetic WT mice was attenuated in DGKzeta-TG mice. Cardiac fibrosis was much less in diabetic DGKzeta-TG than in diabetic WT mice. Western blots showed translocation of PKCbeta and delta isoforms to membrane fraction and decreased Akt/PKB phosphorylation in diabetic WT mouse hearts. However in diabetic DGKzeta-TG mice, neither translocation of PKC nor changes Akt/PKB phosphorylation was observed. CONCLUSION: DGKzeta modulates intracellular signaling and improves the course of diabetic cardiomyopathy. These data may suggest that DGKzeta is a new therapeutic target to prevent or reverse diabetic cardiomyopathy.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"BioMed Central Ltd","subitem_publisher_language":"en"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"1475-2840","subitem_source_identifier_type":"EISSN"},{"subitem_source_identifier":"AA12050431","subitem_source_identifier_type":"NCID"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2008-02-04","bibliographicIssueDateType":"Issued"},"bibliographicPageStart":"2","bibliographicVolumeNumber":"4","bibliographic_titles":[{"bibliographic_title":"Cardiovascular Diabetology","bibliographic_titleLang":"en"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1186/1475-2840-7-2","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"18241357","subitem_relation_type_select":"PMID"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2010-05-24"}],"displaytype":"detail","filename":"1475-2840-7-2.pdf","filesize":[{"value":"791.6 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://fmu.repo.nii.ac.jp/record/2000005/files/1475-2840-7-2.pdf"},"version_id":"c4c8ed3f-7d7c-4e9b-820f-df900c9cc413"}]},"item_title":"Diacylglycerol kinase zeta inhibits myocardial atrophy and restores cardiac dysfunction in streptozotocin-induced diabetes mellitus","item_type_id":"40002","owner":"8","path":["1730783669761"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-05-24"},"publish_date":"2010-05-24","publish_status":"0","recid":"2000005","relation_version_is_last":true,"title":["Diacylglycerol kinase zeta inhibits myocardial atrophy and restores cardiac dysfunction in streptozotocin-induced diabetes mellitus"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2025-01-07T06:26:59.335527+00:00"}
