Voluntary alcohol consumption QTL 1. In the AXB/BXA RI series, significant linkage to alcohol preference mapped to 107 cM on mouse Chromosome 2 near D2Mit74 (LOD=6.13). This locus accounts for 30% of the variance in male and female mice and is named Vacq1 (voluntary alcohol consumption QTL 1). The Vacq1 QTL interval is defined by markers D2Mit148 (105 cM) and D2Mit266 (109 cM). C57BL/6J-derived alleles at Vacq1 confer increased alcohol consumption. Potential candidate genes for Vacq1 are Ntsr1 (107 cM) and Chrna4 (108 cM). Vacq1 appears to be influenced by a locus on mouse Chromosome 15 named Vacq2 (voluntary alcohol consumption QTL 2). Animals homozygous for C57BL/6J-derived alleles at both Vacq1 and Vacq2 exhibit significantly increased alcohol preference.
Ethanol induced LORR Chr# 2 rs13476399(28144658) with right flanking marker rs3713997(3151175) and left marker rs3679483 (179861211). This was mapped in 300 + (b6x129)F2 mice.
The current study used two inbred mouse strains, C57BL/6 J and A/J, to investigate the genetics of behavioral responses to fentanyl. Mice were tested for conditioned place preference and fentanyl-induced locomotor activity. C57BL/6J mice formed a conditioned place preference to fentanyl injections and fentanyl increased their activity. Neither effect was noted in A/J mice. We conducted RNA-sequencing on the nucleus accumbens of mice used for fentanyl-induced locomotor activity. Surprisingly, we noted few differentially expressed genes using treatment as the main factor. However many genes differed between strains.
