The flavonoids, which are the best defined group of polyphenols in the human diet, themselves comprise a large and complex group, all of which contain a three-ring structure with two aromatic centres and a central oxygenated heterocycle. Recent evidence suggests that significant quantities of quercetin and possibly myricetin and kaempferol are absorbed in the gut. A larger fraction probably remains in the lumen, and thus a substantial proportion of the gastrointestinal mucosa is exposed to biologically significant concentrations of these compounds. A substantial body of experimental work has established that flavonoids can suppress carcinogenesis in animal models and there is considerable interest in the biological effects of these compounds at the cellular level. Flavonoids interact with cellular signal pathways controlling the cell cycle, differentiation and apoptosis. Their potentially antineoplastic effects include antioxidant activity, induction of Phase II enzyme activity, inhibition of protein kinases and interactions with Type II estrogen binding sites. Naturally occuring polyphenolic compounds may play a role in the protective effects of fruits and vegetables against cancers in general, and they appear to have considerable potential for pharmaceutical uses as chemopreventive agents against neoplastic changes in the alimentary tract. Future research should therefore focus on the biological effects of flavonoids in the human body, using biomarkers to define their effects at each stage in the onset of neoplasia.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-56263","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"GEE JM,FOOD RES INST,NORWICH LAB;NORWICH RES PK,COLNEY;NR4 7UA NORWICH NORFOLK, ENGLAND.jenny.gee@bbsrc.ac.uk\"","annee":"2001","mois":"9","numero":"8:11","page":"1245-1255","auteurs":[{"ID":6430,"post_author":"0","post_date":"2018-12-03 17:38:15","post_date_gmt":"2018-12-03 16:38:15","post_content":"","post_title":"Ian T Johnson","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"ian-t-johnson","to_ping":"","pinged":"","post_modified":"2018-12-03 17:38:15","post_modified_gmt":"2018-12-03 16:38:15","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/ian-t-johnson\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":56262,"post_author":"0","post_date":"2018-12-04 07:15:08","post_date_gmt":"2018-12-04 06:15:08","post_content":"","post_title":"Gee","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"gee","to_ping":"","pinged":"","post_modified":"2018-12-04 07:15:08","post_modified_gmt":"2018-12-04 06:15:08","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/gee\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":5066,"post_author":"0","post_date":"2018-12-03 17:23:54","post_date_gmt":"2018-12-03 16:23:54","post_content":"","post_title":"CURRENT MEDICINAL CHEMISTRY","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"current-medicinal-chemistry","to_ping":"","pinged":"","post_modified":"2018-12-03 17:23:54","post_modified_gmt":"2018-12-03 16:23:54","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/current-medicinal-chemistry\/","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) -
