TL;DR

This study provides the first cross-tissue proteogenomic evidence that RAB27B is a brain-derived, reproducible candidate protein genetically associated with PPD, and nominate RAB27B and pregnenolone as promising directions for postpartum psychiatric research.

Joint analysis of GWAS and blood and brain QTL summary statistics reveals potential therapeutic targets for neuropsychiatric disorders

Neurological and psychiatric disorders (NPDs) impose a substantial global burden. Many genetic associations have been reported for a range of NPDs, but the specific genes and proteins underlying susceptibility and their tissue- and cell type-specific manifestations remain poorly understood, hindering the developmen...

Multi-Omics Mendelian Randomization Maps Lipid-Related Brain Cell-Type Associations with Kidney Disease

Background: Cellular heterogeneity limits causal inference in complex diseases. We applied an established cell-type-stratified Mendelian randomization (csMR) framework, originally developed by Hao et al. (2024), to investigate whether lipid phenotypes affect kidney disease through distinct brain cell populations, exten...

Proteome-wide Mendelian randomization and transcriptome analysis of a novel osteoarthritis blood-targeting USP8, single-cell model and experimental validation.

This comprehensive genome-wide association meta-analysis revealed new OA-related variants and several blood proteins with possible causal relationships with OA that can contribute to a deeper understanding of the genetic basis of this disease and suggest OA-related pathways as promising targets for further therapeutic...
