Several transcription factors have been implicated in alcohol sensitivity and/or induction of tolerance in flies. The hangover gene encodes a transcription factor that contributes to the induction of alcohol tolerance [90]. Similarly, dLmo/Beadex, which encodes a transcriptional regulator, contributes to behavioral responses to ethanol [91]. The mouse ortholog gene encoding LIM domain only 3 (Lmo3) also affects alcohol sensitivity; reduced Lmo3 expression correlates with increased sedation time and reduces voluntary consumption of ethanol [91].
