KAI-1 and p53 expression in oral squamous cell carcinomas: Markers of significance in future diagnostics and possibly therapeutics.

Abstract

Context:KAI-1/CD82 is a tumor suppressor gene with decreased gene expression being associated with increased invasive ability of oral squamous cell carcinomas (OSCCs). p53 protein functions in the G1-S phase of the cell cycle to allow repair of damaged DNA. In the present study, p53 and KAI-1 expression was investigated using monoclonal antibodies in OSCC.Aims:The aim of this study was to detect KAI-1 and p53 expression in OSCCs and to assess the relation between both in OSCCs.Materials and Methods:The present study included histopathologically diagnosed thirty cases of well- and moderately differentiated OSCCs to study the expression of KAI-1 and p53 antibodies.Statistical Analysis:The results obtained were tabulated and statistically analyzed using descriptive statistical analysis; one-way ANOVA; least square difference method and independent t-test.Results:OSCCs exhibited 41.62% positivity for KAI-1 while p53 positive cells were recorded to an extent of 60.82%. A significant positive correlation was observed between KAI-1 and p53 expression in OSCCs.Conclusions:Although a significant amount of work is still required to uncover the mechanisms of action and regulation of KAI-1 and p53 expression, control of the complex metastatic processes would be of interest in controlling the tumor biology in OSCCs as well as other types of malignancies to enhance prognosis in the affected patients and to help protect against future metastasis in the going to be treated and treated patients.
