( ii ) in contrast , the transcription of the hla-dr alpha was activated by ifn-gamma ( and not by ifn-alpha 2 ) , but the accumulation of -dr alpha gene transcripts was strongly inhibited by cycloheximide or anisomycin , which indicated that there was a requirement for some newly synthesized protein factor ( s ) in this process , apparently at a step subsequent to transcriptional activation .
