However, the involved mechanisms are unknown. Previously, we reported that the dietary flavonoid apigenin could inhibit the proteasome activity and induce apoptosis in tumor cells. To further investigate the structure-proteasome-inhibitory activity relationships, we chose and tested five dietary flavonoids, including luteolin, apigenin, chrysin, naringenin and eriodictyol. We found that the order of inhibitory potencies and apoptosis-inducing potencies of these five compounds in 20S purified proteasome and tumor cells was: (1) luteolin &gt; apigenin &gt; chrysin, and (2) apigenin &gt;&gt; naringenin, and luteolin &gt;&gt; eriodictyol. Therefore, flavonoids with hydroxylized B ring and\/or unsaturated C ring are natural potent proteasome inhibitors and tumor cell apoptosis inducers. Furthermore, neither apigenin nor luteolin could inhibit the proteasome and induce apoptosis in non-transformed human natural killer cells. This finding may provide a molecular basis for the clinically observed cancer-preventive effects of fruits and vegetables.<\/p>\n<p>Publication Types:<br \/>\nResearch Support, N.I.H., Extramural<br \/>\nResearch Support, Non-U.S. Gov&rsquo;t <\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-47514","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"The Prevention Program, Barbara Ann Karmanos Cancer Institute, and Department of Pathology, Wayne State University School of Medicine, Detroit, MI 48201, USA.","annee":"2007","mois":"1","numero":"1:12","page":"1935-45","auteurs":[{"ID":1702,"post_author":"0","post_date":"2018-12-03 16:01:47","post_date_gmt":"2018-12-03 15:01:47","post_content":"","post_title":"Haiping Yang","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"haiping-yang","to_ping":"","pinged":"","post_modified":"2018-12-03 16:01:47","post_modified_gmt":"2018-12-03 15:01:47","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/haiping-yang\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":42317,"post_author":"0","post_date":"2018-12-04 02:47:18","post_date_gmt":"2018-12-04 01:47:18","post_content":"","post_title":"Kitchen","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"kitchen-2","to_ping":"","pinged":"","post_modified":"2018-12-04 02:47:18","post_modified_gmt":"2018-12-04 01:47:18","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/kitchen-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":47011,"post_author":"0","post_date":"2018-12-04 04:10:40","post_date_gmt":"2018-12-04 03:10:40","post_content":"","post_title":"Pachen","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"pachen","to_ping":"","pinged":"","post_modified":"2018-12-04 04:10:40","post_modified_gmt":"2018-12-04 03:10:40","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/pachen\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":47512,"post_author":"0","post_date":"2018-12-04 04:18:18","post_date_gmt":"2018-12-04 03:18:18","post_content":"","post_title":"Dou","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"dou","to_ping":"","pinged":"","post_modified":"2018-12-04 04:18:18","post_modified_gmt":"2018-12-04 03:18:18","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/dou\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":47513,"post_author":"0","post_date":"2018-12-04 04:18:19","post_date_gmt":"2018-12-04 03:18:19","post_content":"","post_title":"Cui","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"cui-2","to_ping":"","pinged":"","post_modified":"2018-12-04 04:18:19","post_modified_gmt":"2018-12-04 03:18:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/cui-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":37465,"post_author":"0","post_date":"2018-12-04 01:17:10","post_date_gmt":"2018-12-04 00:17:10","post_content":"","post_title":"FRONT BIOSCI.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"front-biosci-2","to_ping":"","pinged":"","post_modified":"2018-12-04 01:17:10","post_modified_gmt":"2018-12-04 00:17:10","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/front-biosci-2\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
