Role of Genes in Odontogenesis
Journal Title: Journal of Advances in Medicine and Medical Research - Year 2016, Vol 14, Issue 6
Abstract
With the discovery of the homeobox genes in craniofacial biology researchers across the globe have studied in depth the genetic patterning of the craniofacial region. With respect to craniofacial development –, Barx, Dlx, Gsc, Lim, Msx, Otx, Prx; part of the Hox cluster are important. Barx gene are strongly expressed only in the mesenchyme of the developing molars. Dlx gene expression is noted in the mandibular and maxillary arch ectomesenchyme. Msx genes are expressed in the area of epithelial mesenchymal interactions in the brachial arches in the area of future dentition and also expressed in the formation of skull, facial primordial and sense organs. Msx-1 is seen to be expressed in various stages of tooth formation i.e bud and cap stage of organogenesis. Lim genes which control morphogenesis of the first brachial arch, are expressed in the maxillo-mandibular ectomesenchyme. Prx gene expression is seen in the proximal portion of the mandibular arch. The role of hox genes in the morphogenesis of the jaws and the dentition is immense. Thus it has been proved beyond doubt that the genes have a major role in organogenesis than what human beings have ever envisaged. This review will give the scientific community an overview of all the genes affecting odontogenesis.
