Formation of NSCLP/CP arises from the interaction of environmental and genetic factors. This paper provides a review of recent progress in defining the genetic causes of NSCLP. Methods: A literature review was conducted on the Medline data by searching for the following keywords: genes, non-syndromic cleft lip-palate, and genetics of clefts lip-palates, until January 2018. Results: Various genes are identified in different population and country, with the study using case parent’s trio. The aim of this study contributes to review relative gene which has been identify in non-syndromic cleft lip and palate, and to help to have a better understanding of the inheritance pattern of this pathology and the prevention of genetic disease. Conclusion: Although three major genes have been confirmed, the genetic research is necessary to provide an understanding of the pathophysiology of the clefts lip-palates.展开更多

Methods HOKs were transfected with the plasmid p EGFP-N3-YOD1 containing YOD1. The mR NA levels of YOD1 and TGF-β were determined by q PCR. The protein expressions of YOD1, TGF-β, Smad2/3, Smad4, and phospho-Smad2/3 were determined by western blotting. Cell proliferation and migration were evaluated by Cell Counting Kit-8 assay and wound healing assay, respectively. Results The m RNA and protein levels of YOD1 were higher in HOKs transfected with YOD1. YOD1 overexpression significantly enhanced the migration of HOKs. The mR NA and protein levels of TGF-β3 were increased by YOD1 overexpression. HOKs transfected with YOD1 exhibited increased phospho-Smad2/3 levels. Conclusion YOD1 overexpression enhances cell migration by promoting TGF-β3 signaling which may play an important role in lip and palate formation. YOD1 mutation may contribute to aberrant TGF-β3 signaling associated with decreased cell migration resulting in NSCLP.展开更多
