Hippocampus Gene Expression Correlates for LD_PCT_LIGHT_TIME measured in BXD RI Males obtained using GeneNetwork Hippocampus Consortium M430v2 (Jun06) RMA. The LD_PCT_LIGHT_TIME measures Light-Dark Box Percentage time in light under the domain Basal Behavior. The correlates were thresholded at a p-value of less than 0.001.

QTL spans- 118.3-168.3 Mbp (NCBI Build 37) on Chr3. This interval was obtained by using an interval width of 25 Mbp around the peak marker (Build 37, MGI, http://informatics.jax.org). Ethanol consumption in mice was analyzed in selectively breed mice derived from an F2 population of intercrossed (C57BL/6J x DBA/2J)F1 mice. Whereas C57BL/6J are high consumers of alcohol and DBA/2J are low consumers. The concentration of ethanol used was 10%. With low preference mice and high preference mice mated for a maximum of 4 generations. In generation 4 of the Low selected line a significant QTL was observed and associated with D3Mit17. Authors suggest Adh1 may be a candidate gene.

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_pvalue
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.
