Because IFN -MCP was also blocked in Ad12 E1A -transfected cell lines , expression of one or more of the E1A -conserved regions may be necessary to inhibit IFN -MCP .
 ( protein: IFN, None) , ( cell line: Ad12 E1A -transfected cell lines, None) , ( protein: IFN, None) , ( DNA: E1A -conserved regions, None) , ( DNA: E1A, None) , ( DNA: E1A, None)
