inducer
- n an agent capable of activating specific genes
 - n someone who tries to persuade or induce or lead on
 
- But inducers were virtually abandoned when they proved largely ineffective and, on occasion, highly toxic.
 - Only a foolhardy or a thoroughly self-confident novelist would risk such a potential yawn inducer, and Peter Ackroyd decidedly belongs in the second category.
 - Its plot, after all, places military intelligence, the archetype of self-contradictions, in opposition to another giggle inducer, journalistic ethics.
