However, clinical trials of B-vitamin supplementation including high doses of folic acid have not demonstrated any benefit in preventing or treating cardiovascular disease. In addition to the fact that these clinical trials may have been shorter in duration than appropriate for modulating chronic disease states, it is likely that reduction of the blood homocysteine level may be an oversimplified approach to a complex biologic perturbation. The methionine-homocysteine cycle and folate metabolism regulate redox and methylation reactions and are, in turn, regulated by redox and methylation status. Under normal conditions, a normal redox-methylation balance, or \u201cmethoxistasis\u201d, exists, coordinated by the methionine-homocysteine cycle. An abnormal homocysteine level seen in pathologic states may reflect a disturbance of methoxistasis. We propose that future research should be targeted at estimating the deviation from methoxistasis and how best to restore it. This approach could lead to significant advances in preventing and treating cardiovascular diseases, including heart failure.<\/jats:p>","DOI":"10.3390\/nu5083235","type":"journal-article","created":{"date-parts":[[2013,8,16]],"date-time":"2013-08-16T02:05:47Z","timestamp":1376618747000},"page":"3235-3256","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":64,"title":["Methoxistasis: Integrating the Roles of Homocysteine and Folic Acid in Cardiovascular Pathobiology"],"prefix":"10.3390","volume":"5","author":[{"given":"Jacob","family":"Joseph","sequence":"first","affiliation":[{"name":"Department of Medicine, VA Boston Healthcare System, Boston, MA 02132, USA"},{"name":"Department of Medicine, Brigham and Women's Hospital, Boston, MA 02115, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1153-8047","authenticated-orcid":false,"given":"Joseph","family":"Loscalzo","sequence":"additional","affiliation":[{"name":"Department of Medicine, Brigham and Women's Hospital, Boston, MA 02115, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2013,8,15]]},"reference":[{"key":"ref_1","first-page":"111","article-title":"Vascular pathology of homocysteinemia: Implications for the pathogenesis of arteriosclerosis","volume":"56","author":"McCully","year":"1969","journal-title":"Am.
