Clarification of the relationship between the functions of E1AF gene and the invasion and metastasis of cancers, and application thereof to cancer control, more specifically the control of cancer cell invasion by controlling the expression of E1AF gene and the products of expression, and the detection and diagnosis of cancers by detecting the products of expression of E1aF gene.
1. A method for detecting cancers comprising detecting a product expressed by E1AF gene, wherein said E1AF gene encodes the amino acid sequence shown as SEQ ID NO:5.
2. The method according to claim 1 wherein the product expressed is mRNA.
3. The method according to claim 2 wherein the product expressed is the expressed protein E1AF protein.
4. A method for diagnosing cancer tissue invasion comprising detecting a product expressed by E1AF gene in isolated human cancer tissue, wherein said E1AF gene encodes the amino acid sequence shown as SEQ ID NO:5.
5. The method according to claim 4 wherein the product expressed is mRNA.
6. The method according to claim 4 wherein the product expressed is E1AF protein.
