KAI1, recognized as a tumor metastasis suppressor gene, is known to impede tumor cell metastasis by either enhancing intercellular adhesion or diminishing the adhesion between cells and the extracellular matrix.[19] In our investigation, we observed that the positive expression rate of KAI1 in cervical squamous cell carcinoma tissues was markedly lower compared to that in the corresponding non-tumor control tissues. This evidence concerns the gene CD82 and neoplasm.
