Changes in the expression of class I major histocompatibility complex antigen RNA induced by interferon in rat hepatoma cells.
The rat hepatoma cell line 17X was studied to determine if it expressed major histocompatibility complex (MHC) class I antigen RNA and to see if interferon treatment would affect its expression. Under normal cell culture conditions, MHC class I RNA in 17X hepatoma cells is virtually undetectable. Administration of rat interferon at a concentration of 1000 units/ml for 48 h to 17X cells in culture resulted in the appearance of detectable levels of RNA for MHC class I antigens. The interferon-induced increase in class I RNA was accompanied by de novo synthesis of immunoprecipitable, metabolically radiolabeled class I antigens in the 17X hepatoma cells.
