Transcriptomic Analysis of the Human Habenula in Schizophrenia.
Article in The American journal of psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe objective of this study was to define the molecular neuroanatomy of the human habenula (Hb) and identify transcriptomic differences between brains of individuals with schizophrenia and nonpsychiatric control brains.
methodsThis study utilized Hb-enriched postmortem human brain tissue. Single-nucleus RNA sequencing (snRNA-seq) was conducted to identify molecularly defined Hb cell types (N=7 donors), and single-molecule fluorescent in situ hybridization (smFISH) was performed to validate cell types and map their spatial locations (N=5 independent donors). Bulk RNA sequencing (RNA-seq) (schizophrenia, N=35; nonpsychiatric control, N=33) and cell type deconvolution were used to identify differentially expressed genes (DEGs), which were then compared to dorsolateral prefrontal cortex, hippocampus, and caudate schizophrenia DEGs. Expression quantitative trait loci (eQTLs) and schizophrenia risk colocalization analyses were performed.
resultssnRNA-seq identified 17 cell type clusters across 16,437 nuclei, including three medial and seven lateral Hb populations, several of which were conserved in rodents. smFISH validated snRNA-seq Hb cell types and depicted their spatial organization. Bulk RNA-seq analyses yielded 173 schizophrenia-associated DEGs (false discovery rate<0.1), of which 129 (75%) were unique to Hb-enriched tissue. eQTL analysis identified 717 independent single-nucleotide polymorphism (SNP)-gene pairs (false discovery rate<0.05). Of these, 16 pairs included a SNP that is a schizophrenia risk variant, and seven different pairs included a schizophrenia DEG. eQTL and schizophrenia risk colocalization analysis identified 16 colocalized genes, nine of which have not been previously identified.
conclusionsThese results identify topographically organized cell types with distinct molecular signatures in the human habenula and demonstrate unique genetic differences associated with schizophrenia, thereby providing novel molecular insights into the role of the habenula in neuropsychiatric disorders.
