摘要
The mRNA differential display method detected increased expression of the mRNA of an immune recognition antigen known as Ly-6A/E after malignant transformation of the murine squamous cell carcinoma line Pam 212, Subsequent loss of expression of Ly-6A/E occurred with metastatic tumor progression of Pam in vivo. Ly-6 molecules have been implicated in immune cell recognition and signal transduction and are homologous to the human E48 SCC antigen that has been shown to be involved in cell-cell recognition. These observations suggest that loss of Ly-6A/E antigen may contribute to tumor progression and metastasis of squamous cell carcinoma through decreased tumor-lymphocyte or tumor-tumor recognition.
