QTL for nicotine sensitivity on Chr8 at D8Mit124 (13.44 Mbp , Build 37)
Description:
nicotine sensitivity spans 0.00 - 38.44 Mbp (NCBI Build 37) on Chr8. This interval was obtained by using an interval width of 25 Mbp around the peak marker (Build 37, MGI, http://informatics.jax.org).
alcohol preference spans 0.00 - 40.29 Mbp (NCBI Build 37) on Chr8. This interval was obtained by using an interval width of 25 Mbp around the peak marker (Build 37, MGI, http://informatics.jax.org).

Ethanol Induced Ataxia Chr#8 rs3699406 (72486070) with right flanking marker rs6386110 (45897379) and left marker rs13479995(116236688). This was mapped in 300 + (b6x129)F2 mice.
Analysis using RNA-seq of FACS-purified oligodendrocytes revealed a large cohort of morphine-regulated genes. In addition, to investigate cell-type-specific opioid responses, we performed single-cell RNA sequencing (scRNA-seq) of the nucleus accumbens of mice following acute morphine treatment. Differential expression analysis uncovered unique morphine-dependent transcriptional responses by oligodendrocytes and astrocytes.

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.
