The effects of the Sp and Wnt genes on abnormalities in embryonic developmental and cleft lip and palate

Abstract

Normal embryonic development is regulated by different genes and related signaling pathways. In recent years, the association between different genes and genes, genes and signaling pathways in the same organization has been widely concerned by scholars at home and abroad. Sp and Wnt gene deletion or mutation can lead to abnormal em⁃ bryonic development. The results of this review indicate that abnormal embryonic development is due to Sp gene dele⁃ tion/mutation The zinc finger protein superfamily member Sp1⁃9 is involved in the development of various tissues and organs , such as the hematopoietic system, respiratory system and skeletal system, and its deletion or mutation can lead to developmental abnormalities in embryonic tissues. In addition, the Sp8 gene is associated with the occurrence of cleft palate. By summarizing the observations about the relationship between the Wnt gene and cleft lip and palate in recent years, we can understand the abnormal expression of Wnt3, Wnt3A, Wnt5A, Wnt9B, Wnt10A and Wnt11 in humans. The occurrence of cleft lip and palate is closely related; Sp5/8 is a key downstream effector of the Wnt signaling path⁃ way during embryonic development and participates in the Wnt signaling pathway. Sp5/8 and the Wnt signaling pathway are involved in the regulation of normal neural crest development and the self⁃renewal of embryonic stem cells in embry⁃ onic mice. In summary, this paper proposes that the Sp and Wnt genes may be involved in the regulation of the forma⁃ tion and occurrence of embryonic cleft palate and provides a reference for further study of the associated mechanisms between the two genes in the cleft palate model.
