- Epidemiological and clinical observations linking schizophrenia (SCZ) to increased dementia risk, together with the occurrence of psychosis in Alzheimer's disease and related dementias (ADRD), suggest that shared genetic liabilities may contribute to their co-occurrence. Leveraging large-scale genome-wide association study summary statistics for SCZ (53,386 cases and 77,258 controls) and ADRD (111,326 cases and 677,663 controls), we systematically investigated their shared genetic architecture and potential biological mechanisms. We identified three significant local genetic correlations (P < 2.0 × 10⁻⁵) and cross-trait polygenic enrichment between SCZ and ADRD, with 39 genomic loci jointly associated at conjunctional false discovery rate (conjFDR) < 0.05. Fifteen high-confidence genes (CNIH4, CD302, PCGF3, TFR2, EPHX2, SNX32, EFEMP2, CTSW, ASPHD1, TAOK2, INO80E, DOC2A, MAPK3, KANSL1, and XPNPEP3) were consistently prioritized across positional, expression quantitative trait locus, and chromatin-interaction mapping. Tissue- and cell-type enrichment analyses highlighted cerebellar tissues and ependymal-cell-related signals, while pathway analyses implicated synaptic signaling, axonal growth, and presynaptic structural organization. At the locus level, colocalization and transcriptome-wide association analyses converged on 16p11.2, prioritizing INO80E, YPEL3, SLX1B, and TMEM219. Developmental trajectory modeling further revealed region- and stage-specific expression divergence of prioritized 16p11.2 genes, with prominent differences spanning childhood and adulthood. Brain-wide association analysis linked the 16p11.2 lead variant rs9932702 to cortical gray-white contrast (β = -0.062, P = 7.5 × 10⁻¹⁵), a neuroimaging phenotype related to gray-white boundary microstructure and myelination. Finally, bidirectional Mendelian randomization supported a modest directional association between genetic liability to SCZ and increased ADRD risk, but not the reverse direction. Collectively, these findings provide convergent genetic, regulatory, transcriptomic, developmental, and imaging evidence for partial shared liability between SCZ and ADRD, highlighting 16p11.2 and biological processes related to neurodevelopment, synaptic and axonal organization, myelination-related microstructure, and later-life brain vulnerability. - Source: PubMed

Chen JingYin QiXu ShihengTan XiaoqingLiang YuChen ChaohuiLi LiZhang TaoShen Tao - Polycomb group proteins mediate epigenetic repression via multisubunit complexes, including canonical Polycomb Repressive Complex 1 (PRC1), which monoubiquitylates histone H2A and binds histone H3 trimethylated at lysine-27 (H3K27me3). The RING1 subunit of PRC1, critical for H2A ubiquitylation, forms other complexes. These variant RING1 complexes also ubiquitylate H2A but cannot bind H3K27me3, and their role in epigenetic repression is debated. Using genetics, we found that canonical PRC1 and variant RING1 complexes ubiquitylate H2A at distinct genomic regions. We established that the PCGF protein specific for variant RING1 complexes, which we named Siesta, is not required for epigenetic repression of developmental genes but controls larval locomotion independently of H2A ubiquitylation. Leveraging a massively parallel transgenic approach, we demonstrated that H2A ubiquitylation has minimal impact on transcriptional repression. Our findings imply that Siesta-RING1 complexes operate outside the Polycomb regulatory system and that the popular PRC1 classification will benefit from revision. - Source: PubMed

Kahn Tatyana GGarrido AndresYushkova AnastasiyaKim MariaGlotov AlexanderSreekumar SwedaLarsson JanSchwartz Yuri B - Type I interferons （IFN-I） are key proteins in antiviral response and immunomodulation. Negative regulators avoid abnormal activation of the interferon pathway or overactivation of interferon-activating proteins through multiple mechanisms. Loss-of-function mutations in negative regulator genes lead to the development of a variety of type I interferonopathy. It is of great significance in theory and clinic to discover new negative regulators and study their functions, but there is no effective screening system at present. Here, a screening system is established through a resistance reporter, which is designed to be expressed only in cells with interferon pathway activation. In conjunction with CRISPR knockout library, cells are screened for interferon pathway activation due to knockout of negatively regulators, which led to the identification of negatively regulator candidate genes such as PCGF3/5, UCK2, and ITPKA. The expression products of these genes functioned by targeting MAVS and promoted EMCV (encephalomyocarditis virus) infection by inhibiting interferon pathway activation. This study deepens the understanding of the regulatory network of the interferon pathway and provides a new theoretical basis for the study of the pathogenesis of autoimmune diseases. - Source: PubMed

Pang ZhaojunYang HanLi BoLiu YifuZhao ZhenxiangZhu ZixiangPeng ShouchunMu XinYu Hongjian - DNA methylation in brain regions represents a potential mechanism linking genetic variation to Alzheimer's disease (ad) risk, yet most studies have focused on blood-derived methylation markers. In this study, we conducted a systematic Mendelian randomization (MR) study to evaluate associations between predicted brain region-specific DNA methylation levels and ad risk, using methylation quantitative trait loci (mQTL) as genetic instruments. - Source: PubMed
