Methylated microRNA genes of the developing murine palate.

ABSTRACT: Environmental factors contribute to the etiology of cleft palate (CP). Environmental factors can also affect gene expression via alterations in DNA methylation suggesting a possible mechanism for the induction of CP. Identification of genes methylated during development of the secondary palate provides the basis for examination of the means by which environmental factors may adversely influence palatal ontogeny. We previously characterized the methylome of the developing murine secondary palate focusing primarily on protein- encoding genes. We now extend this study to include methylated microRNA (miRNA) genes. A total of 42 miRNA genes were found to be stably methylated in developing murine palatal tissue. Twenty eight of these were localized within host genes. Gene methylation was confirm
