It is well known that folic acid supplementation decreases about 70% of all NTDs, although the mechanism by which this occurs is still relatively unknown. The current theory is that folic acid deficiency ultimately leads to depletion of the methyl pool, leaving critical genes unmethylated, and, in turn, their improper expression leads to failure of normal neural tube development. Recently, new studies in human cell lines have shown that folic acid deficiency and DNA hypomethylation can lead to misexpression of microRNAs (miRNAs). Misexpression of critical miRNAs during neural development may lead to a subtle effect on neural gene regulation, causing the sometimes mild to severely debilitating range of phenotypes exhibited in NTDs. This review seeks to cohesively integrate current information regarding folic acid deficiency, methylation cycles, neural development, and miRNAs to propose a potential model of NTD formation. In addition, we have examined the relevant gene pathways and miRNAs that are predicted to affect them, and based on our investigation, we have devised a basic template of experiments for exploring the idea that miRNA misregulation may be linked to folic acid deficiency and NTDs. genesis 48:282\u2013294, 2010. \u00a9 2010 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/dvg.20623","type":"journal-article","created":{"date-parts":[[2010,3,12]],"date-time":"2010-03-12T14:08:32Z","timestamp":1268402912000},"page":"282-294","source":"Crossref","is-referenced-by-count":45,"title":["A new perspective on neural tube defects: Folic acid and microRNA misexpression"],"prefix":"10.1002","volume":"48","author":[{"given":"J.M.","family":"Shookhoff","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.
