Increased behavioral responses to ethanol in Lmo3 knockout mice.

ABSTRACT: LIM-domain-only 3 (LMO3) is a transcriptional regulator involved in central nervous system development and neuroblastoma. Our previous studies implicated a potential role for LMO3 in regulating ethanol sensitivity and consumption. Here, we examined behavioral responses to ethanol in a line of Lmo3 null (Lmo3(Z) ) mice, utilizing the ethanol-induced loss-of-righting-reflex (LORR) test, two-bottle choice ethanol consumption and the drinking in the dark (DID) test, which models binge-like ethanol consumption. We found that Lmo3(Z) mice exhibited increased sedation time in response to ethanol in the LORR test and drank significantly more ethanol in the DID test compared with their wild-type counterparts, but showed no differences in two-bottle choice ethanol consumption. To explore where LMO3
