The present report will summarize novel findings of ITCs on histone deacetylase activity, DNA methylation, and short noncoding microRNAs, focusing on sulforaphane (SFN) from broccoli and phenethylisothiocyanate from watercress.<\/p>\n<p>RECENT FINDINGS: In a human intervention study, broccoli sprouts led to more efficient histone deacetylase inhibition in blood cells than a broccoli sprout supplement, correlating with higher levels of urinary ITC metabolites. A proteomics study with C-labeled ITCs revealed among others a direct interaction with histones and chromatin-modulating proteins. The well investigated Kelch-like erythroid-cell-derived protein with CNC homology-associated protein 1\/nuclear factor erythroid 2-related factor 2\/antioxidant-response element pathway is both affected by and mechanistically involved in epigenetic activities of ITCs. Accordingly, reduction of oxidative stress is shown to prevent hypertension-associated global hypomethylation in rats. Combination of SFN with (-)-epigallocatechin gallate as a demethylating agent is identified as an effective approach for re-expression of estrogen receptor in hormone negative breast cancer. Induction of miR-200c by SFN prevents epithelial-mesenchymal-transition and could be relevant for prevention of metastases.<\/p>\n<p>SUMMARY: The last year has identified interesting areas of ITCs affecting epigenetic mechanisms that will have implications for translational cancer (prevention) research once validated in animal studies and human intervention studies.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-34401","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Division of Epigenomics and Cancer Risk Factors, German Cancer Research Center (DKFZ), Heidelberg, Germany.","annee":"2013","mois":"7","numero":"16:4","page":"405-410","auteurs":[{"ID":34400,"post_author":"0","post_date":"2018-12-04 00:28:49","post_date_gmt":"2018-12-03 23:28:49","post_content":"","post_title":"Gerhauser","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"gerhauser","to_ping":"","pinged":"","post_modified":"2018-12-04 00:28:49","post_modified_gmt":"2018-12-03 23:28:49","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/gerhauser\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":30258,"post_author":"0","post_date":"2018-12-03 23:29:45","post_date_gmt":"2018-12-03 22:29:45","post_content":"","post_title":"CURR OPIN CLIN NUTR METAB CARE","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"curr-opin-clin-nutr-metab-care","to_ping":"","pinged":"","post_modified":"2018-12-03 23:29:45","post_modified_gmt":"2018-12-03 22:29:45","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/curr-opin-clin-nutr-metab-care\/","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) -
