However , when a second , upstream IRE - like sequence was evaluated by EMSA , a DNA binding pattern distinct from that seen following exposure to IFN - gamma alone was observed after prolonged stimulation with both IFN - alpha and IFN - gamma .
 GENE: upstream IRE - like sequence; GENE: IFN - gamma; GENE: IFN - alpha; GENE: IFN - gamma
