Microarrays were used to investigate the gene expression profiles of different brain regions within the limbic system of mice which were selectively bred for either high (HAB) or low (LAB) anxiety-related behavior, and also show signs of comorbid depression-like behavior. This gene set contains significantly differentially expressed genes between HAB and LAB mice. Brain regions include the hypothalamic paraventricular nucleus (PVN), the supraoptic nucleus (SON), the basolateral (BLA) and central (CeA) amygdala, and the cingulate cortex (Cg), as well as the nucleus accumbens (NAc) and dentate gyrus (DG). Statistics reported as p-value.

Dysregulation of NRSF/REST via EHMT1 is associated with psychiatric disorders and Kleefstra syndrome, Z scores
Description:
EHMT1 is an epigenetic repressor that is causal for Kleefstra Syndrome (KS), a neurodevelopmental disorder (NDD) leading to intelectual disability, and is associated with schizophrenia. Here, the researchers aim to show we show that reduced EHMT1 activity decreases NRSF/REST protein leading to abnormal neuronal gene expression and progression of neurodevelopment in human iPSC. Five induced pluripotent stem cell samples (from fibroblasts of adult, male, skin) were used. The stem cells were gifted from: Lieber Institute for Brain Development, Johns Hopkins Medical Campus. Total RNA extracted from a control hiPSC line and control cells treated for 72h with various concentrations of UNC0638 i.e 50, 100, 200 or 250nM as a model for Kleefstra syndrome. Polyadenylated adaptors were ligated to the 3′-end, 5′-adaptors were then ligated, and the resulting RNAs were reverse transcribed to generate cDNA that can be amplified by PCR. The amplified product was run on low range ultra agarose in TBE buffer and a size-selection was performed to ensure that the cDNA used for sequencing primarily contains miRNAs rather than other RNA contaminants. Expression values were calculated by the method detailed in 'HBA-DEALS: accurate and simultaneous identification of differential expression and splicing using hierarchical Bayesian analysis' (Genome Biol. 2020, PMID: 32660516), and Z scores calculated. Genes were annotated as Ensembl gene ids. SRA Study id ERP130338.

The dataset used in this study (Bulk RNA-Seq) was previously published and can be found at NCBI GEO (GSE182321), this analysis was conducted by GEO2R to compare control and OUD samples, only top differentially expressed genes are reported. To understand mechanisms and identify potential targets for intervention in the current crisis of opioid use disorder (OUD), postmortem brains represent an under-utilized resource. To refine previously reported gene signatures of neurobiological alterations in OUD from the dorsolateral prefrontal cortex (Brodmann Area 9, BA9), we explored the role of microRNAs (miRNA) as powerful epigenetic regulators of gene function.

Description:
doi: https://doi.org/10.1101/2024.01.12.24301153. This study is a re-analysis of publicly available data and a meta-analysis investigating differential gene expression associated with opioid use disorder from Corradin et al. 2022 (PMID: 35301427); Mendez et al. 2021 (PMID: 34385598); Seney et al. 2021 (PMID: 34380600); and Sosnowski et al. 2022 (PMID:36845993 ). All four of these studies used human postmortem dorsolateral prefrontal cortex (DLPFC) brain tissue from donors identified as dying from OOD through toxicology assays administered by forensic scientists and phenotypic evidence of opioid addiction. Each of these independent studies had modest sample sizes (N = 40-153) and compared bulk RNA-seq data from individuals who died from OOD to individuals who died from non–drug use causes.

The genomic structural equation modeling (gSEM) analysis includes results on european ancestry (EA) from the Genetics of Opioid Addiction Consortium (GENOA) meta-analysis, Million Veteran Program (MVP), Psychiatric Genetics Consortium Substance Use Disorders Group (PGC-SUD), and the Partners Health cohorts. The MVP results are based on a meta-analysis including MVP parts 1 and 2 (total of 8529 OUD cases and 71,200 opioid-exposed controls), along with Yale-Penn and Study of Addiction: Genetics and Environment (SAGE) cohorts (total of 10,544 OUD cases and 72,163 opioid-exposed controls). The PGC-SUD results include 4,503 opioid dependence cases and 4173 unexposed controls. Unexposed controls are used for the PGC-SUD because the exposed controls results have negative heritability estimates. The partners health cohort includes 1,039 OUD cases and 10,743 exposed controls. Note that the GENOA GWAS, Yale-Penn, and SAGE parts of the MVP, and the PGC-SUD results include overlapping samples. However, accounting for this sample overlap is a feature of the gSEM approach applied in this study. A total of 2,434,903 variants were present in all cohorts and tested for association with the OA latent variable in the gSEM analysis using a total sample size of 403,915 (23,367 cases and 384,619 controls; effective sample size of 88,114). Gene-based associations with OA were calculated from the gSEM summary statistics with MAGMA v1.0841 with a 10 kb gene window via the Functional Mapping and Annotation (FUMA) of GWAS web tool v1.3.6a. The gSEM summary statistics were mapped to 15,977 protein coding genes, resulting in a Bonferroni-corrected threshold of p=3.129e-6 for declaring genome-wide significance. All genes and p-values are presented from the MAGMA analysis.

Human induced pluripotent stem cell (iPSC) lines, A and B, derived from two healthy adult male individuals, were used to generate hCOs for RNA-sequencing. Methodone treatment began on Day 9 of organoid culture, the first day of the neural proliferation stage, and concluded at Day 60. Nuclease-free water was used as a vehicular control. Cortical organoids were collected 2 months (60 days) after initiating organoid culture. Each well of hCOs (15–20 organoids) was a separate biological replicate for a given treatment condition (i.e., treated or untreated). RNA was extracted from frozen organoid pellets using the Direct-Zol Miniprep Plus Kit (Zymo, Irvine, CA) according to the manufacturer’s instructions. Samples were multiplexed and sequenced on the Illumina NovaSeq 6000 S4 to produce approximately 100 million, 100 base pair, paired end reads per sample. 3 control and 3 methadone-treated samples were sequenced from cell line A, and 4 control and 4 treated samples from cell line B. Raw fastq file quality assessment and read alignment to the hg19 genome (GRCh37, RefSeq GCF_000001405.13) were performed. Significantly differentially expressed genes (DEGs) were selected based on the confident effect size of their log2(Fold Change) values at FDR<0.05. Genes presented are without cutoffs and were obtained using the GEO2R tool by GW curators (GEO accession: GSE210682).

DEG Huh7.5JFH1 liver cells fentanyl vs control_pvalue
Description:
Differential mRNA expression of liver cells exposed to fentanyl vs control in human liver cells. The Huh7.5JFH1 and HepG2.2.15 hepatocyte cell lines were seeded at 500,000 cells per well. Fentanyl or carfentanil was added to culture medium after 24 hours. After 24 hours of incubation with drug, hepatitis C virus (HCV) core (ng/mL), or hepatitis B surface antigen (HBsAg) (ng/mL) was quantified in culture supernatants. Differential expression was assessed using moderated t-tests with a cutoff of p < 0.05 and fold change > 1.25. Transcripts meeting significance criteria were submitted to ToppGene and ToppCluster for ontological analyses. RNAseq data are available through GEO using accession number GSE167922. Differential expression of mRNA in fentanyl treated vs control cells was analyzed for each cell line using the GEO2R tool.

Based on the disinhibited externalizing spectrum described by Krueger et al. (1), we collected GWAS summary statistics for 13 externalizing phenotypes (Table 1). Only samples with a European/North-American ancestry (23) were included (see Supplement 1). Assessment of genetic resemblance indicated a categorization into two externalizing-related factors, one characterized by disruptive behavior (DB) and another by risk-taking behavior (RTB), that together explained 53% of the total genetic variance. Hierarchical clustering on genetic resemblance (Figure 1B) confirmed this categorization into DBs (aggression, angry outbursts, different measures of irritability, and ADHD) and RTBs (antisocial behavior, general risk tolerance, drinks per week, ever smoker, number of sexual partners, automobile speeding propensity, and lifetime cannabis use). For these phenotypes, we followed the hierarchical clustering results, assigning ADHD to factor 1 (DB) and antisocial behavior to factor 2 (RTB). The author defined alpha level for significant associations in this geneset is alpha = 2.75E-06 (table S13).
