microRNAs (miRs) are small RNA molecules that regulate many cellular and developmental processes. They control gene expression pathways during specific developmental time points and are required for tissue homeostasis and stem cell maintenance. miRs as therapeutic reagents in tissue regeneration and repair hold great promise and new technologies are currently being designed to facilitate their expression or inhibition. Due to the large amount of miR research in cells and cancer many cellular processes and gene networks have been delineated however, their in vivo response can be different in complex tissues and organs. Specifically, this report will discuss animal developmental models to understand the role of miRs as well as xenograft, disease, and injury models. We will discuss the role of miRs in clinical studies including their diagnostic function, as well as their potential ability to correct craniofacial diseases.
Many dietary plants possess high levels of 18-carbon containing lipids from both omega-6 and omega-3 unsaturated fatty acids (e.g., linoleic and alpha-linolenic acid, respectively). These dietary lipids can be metabolized to lipid mediators collectively termed octadecanoids, which can in turn interact with immune cells (e.g., macrophages, eosinophils) to exert a number of potent biological effects. These octadecanoid lipid mediators have been little studied and represent an exciting new area of lipid biochemistry.
