Fig. 1From: MicroRNAs in oral fluids (saliva and gingival crevicular fluid) as biomarkers in orthodontics: systematic review and integrated bioinformatic analysisA simplified diagram explaining the pathway of microRNA (miRNA) dependent gene expression. Shows processing of three different types of miRNA, pri-miRNA in nucleus, pre-miRNA migration to cytoplasm, processing of mature mi-RNA in cytoplasm. Inputs from [1, 2]Back to article page
