The IFN -dependent increase in RAR(alpha) levels and the enhancing effect of the cytokine on retinoid -dependent granulocytic markers expression may be a characteristic of PML-RAR positive cells , since the phenomena are not observed in HL-60 promyelocytes .
 cell line: PML-RAR positive cells; cell line: HL-60 promyelocytes; protein: IFN; protein: cytokine; protein: RAR(alpha); protein: PML-RAR; protein: retinoid -dependent granulocytic markers
