Using 38 progeny from ISCS (Interval-specific congenic strains) lines 2 and 11 the mapping of Lore5 was refined to a region of mouse Chromosome 15 bounded by D15Mit84 (39987672 NCBI 37) and D15Mit121 (57990385 NCBI 37).

Acute and chronic alcohol exposure was analyzed in 534 (C57BL/6J x C3H/HeJ)F2 mice. Behavioral testing was done using 5 traits, acute drug effect, forced ethanol drinking, withdrawal studies ethanol preference and stress induced ethanol drinking. The following QTL were found in a genome wide scan: Following the QTL is the Chromosome , cM location, and LOD score, Eih1 (Chr 1, 85 cM, LOD 6.6), Eih2 (Chr 7, 10 cM, LOD 3.6), Ceih1 (Chr 3, 55 cM, LOD 4.1), Ceih2 (Chr 6, 24.7 cM, LOD 4.1), Ceih3 (Chr 13, 39 cM, LOD 4.1), Eia1(Chr 1, 65 cM, LOD 10.3 and 10.4), Eiwa1 (Chr 7, 50 cM, LOD 4.4), Eiwa2(Chr 11, 43.1 cM, LOD 4.1),Aldd1(Chr 5, 42 cM, LOD 13.2), Aldd2(Chr 12, 18 cM, LOD 5.3),Eiwax1(Chr 1, 79 cM, LOD 6.5), Eiwax2(Chr 5, 59 cM, LOD 15.0), Eiwax3(Chr 12, 21 cM, LOD 3.6), Methp1(Chr 16, 31.4 cM, LOD 4.3), Mec1(Chr 16, 19.4 cM, LOD 5.1), Epbs1(Chr 16, 33 cM, LOD 4.1), Ecbs1(Chr 16, 29.4 cM, LOD 4.8), Mec2(Chr 1, 109 cM, LOD 3.9), Mec3(Chr 2, 109 cM, LOD 4.3), Mec4(Chr 5, 29 cM, LOD 3.9), Mec5(Chr 10, 2 cM, LOD 5.0), Mec6(Chr 15, 49 cM, LOD 5.2, 95% CI 6.7–56.7).

QTL for Voluntary Ethanol Consumption on LS x SS RI lines spans 43765164-93765164 .This interval was obtained by using an arbitrary interval width of 25 Mbp around the peak marker (Build 37, MGI, http://informatics.jax.org). Chr 15 D15Mit3 39 cM VEC (females) 0.02
In the present study Aaq1, a previously mapped QTL on mouse Chromosome 15 linked to alcohol acceptance, is confirmed using a (C57BL/6J x DBA/2J)F2 population. Aaq1 mapped to 15 cM (D15Mit60)- 48 cM (D15Mit34) on mouse Chromosome 15 with a peak LOD score of 3.8 at approximately 30 cM. C57BL/6J-derived alleles confer increased alcohol acceptance in a dominant fashion at Aaq1. A potential candidate gene for Aaq1 is the peripheral benzodiazepine receptor gene, Bzrp.

Analysis of 2 Lore5 interval specific congenic strains (ISCS) excluded Mapk8ip as a candidate gene for Lore5. The Lore5 interval appears to be localized between D15Mit94 (29 cM) and D15Mit93 (43.7).

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.

Differential gene expression in nucleus accumbens somatostatin interneurons_cocaine_mice_logFC
Description:
To characterize transcriptional alterations that cocaine induces in these cells, we perform cell type-specific RNA-sequencing on FACS-isolated nuclei of somatostatin interneurons and identified 1100 DETs enriched for processes related to neural plasticity. To profile the entire (non poly-A selected) transcriptome of NAc somatostatin interneurons, we generated a transgenic reporter line (SST-TLG498 mice) to label the nuclei of these cells with a modified form of EGFP that is retained in the nuclear membrane (EGFP-F)22, enabling their isolation from NAc dissections using FACS. We succeeded in FACS-isolating nuclei suitable for RNA-sequencing from individual SST-TLG498 mice. We proceeded with differential expression analysis of the RNA-sequencing data to identify differentially expressed transcripts (DETs) in NAc somatostatin interneurons in response to repeated cocaine exposure: 778 transcripts were upregulated by cocaine and 322 were downregulated.
