ABSTRACT
14-3-3 protein is a highly conserved soluble acid family. Recent researches suggest that they play critical regulatory roles in cellular processes such as cellular mitosis,growth,differentiation,proliferation and death,etc.14-3-3sigma protein,one member of the family,expresses mainly in epithelial cells and has histological specificity.14-3-3sigma protein interacts with several signal transduction proteins,induces cell cycle arrest in G2 phase after DNA damage,and regulates cellular biological functions.Abnormal expression of 14-3-3? sigma protein is common during tumor transformation,which may be induced by p53 mutation or CpG island hypermethylation of promoter. It is closely related with the transformation,progress and prognosis of human malignant tumors.
