Li WeitaoYu ShaZhu BiyunChen LihengLi HuaweiGuo LuoShu YilaiChen Bing - Hearing loss is the most common sensory organ disorder, with genetic factors contributing substantially to the disease. Among the 87 genes responsible for autosomal recessive nonsyndromic hearing loss, mutations in MPZL2 have been frequently linked to mild-to-moderate autosomal recessive hearing loss (DFNB111). Here, we present multiple families whose hearing loss arose from biallelic mutations in the MPZL2 gene and found that the MPZL2 p.Q74∗ mutation may be a founder allele among East Asians. Furthermore, we generated an Mpzl2 p.Q74∗ knockin mouse model that exhibited autosomal recessive, progressive, ski-sloping hearing loss with Deiter's cell degeneration. Gene supplementation using AAV-DJ or AAV-PHP.eB to deliver human MPZL2 (hMPZL2) under control of the CAG promoter induced ototoxicity, whereas employing an alternative EF1α promoter with AAV-DJ (DJ-EF1α-hMPZL2) circumvented this issue, restoring long-term auditory function and Deiter's cell survival in Mpzl2 mice for up to 24 weeks. Overall, this study provides the foundational steps for developing a safe and effective biological treatment for DFNB111 and underscores the importance of precise regulation of target cells and transgene expression in AAV-based treatments. - Source: PubMed

Jang Seung HyunSong Hyeong GiJoo Sun YoungKim Jung AhKim Se JinChoi Jae YoungJung JinseiGee Heon Yung - Prelingual sensorineural hearing loss (SNHL) represents about 80% of genetic SNHL, with at least 90 causative genes identified. In order to identify the genetic diagnosis of prelingual SNHL, we performed a prospective study by systematic history-taking and phenotyping, followed by whole-exome sequencing (WES) with target gene analysis in 100 Thai patients. We found an overall diagnostic yield of 46%, 58.3% for familial cases, and 39.0% for sporadic cases. These included 41 cases with nonsyndromic SNHL(nsSNHL) and 5 cases with syndromic SNHL (sSNHL). We identified 41 P/LP and 4 VUS variants of 15 genes. Of those sSNHL, the causative genes were PAX3, SOX10, MITF (Waardenburg and Teitz syndromes), and SLC26A4 (Pendred syndrome). The genetic defects identified among those with nsSNHL were GJB2 and SLC26A4 as the most prevalent causes, followed by MYO15A, MYO7A, POU3F4, OTOF, PCDH15, GSDME, PTEN, ACTG1, TMPRSS3, MITF, and MPZL2. The inheritance of these nsSNHL genes involved X-linked recessive (n = 3), autosomal dominant (n = 3), and autosomal recessive in the remainder (n = 36). Patients with positive mutations underwent surveillance for associated symptoms like goiter and retinitis pigmentosa. In conclusion, most prelingual SNHL was nsSNHL with autosomal recessive inheritance. Identifying the causative gene benefits patients for specific management and genetic counseling. - Source: PubMed

Here, we identify an East Asia-specific founder mutation, the homozygous c.220 C > T mutation in MPZL2, that contributes to a significant proportion of hereditary deafness cases in our cohort study. We find that the disease-causing mutation can be targetable by adenine base editors (ABEs) that enable A·T-to-G·C base corrections without DNA double-strand breaks. To demonstrate this, we develop a humanized mouse model (hMPZL2) that recapitulates human MPZL2 deafness and leads to progressive hearing loss. A PAM-flexible ABE variant with reduced bystander and off-target effects (ABE8eWQ-SpRY:sgRNA3) is packaged in dual adeno-associated viruses (AAVs) and injected into the inner ear of hMPZL2 mice and effectively corrects the mutation. This treatment significantly restores hearing function, improves inner ear structural integrity, and reverses altered gene expression. Base editing may hold therapeutic potential for hereditary deafness, including most cases of MPZL2 deafness. - Source: PubMed

This study examines key genes associated with sepsis and Alzheimer's disease (AD), as well as their potential molecular mechanisms. We downloaded the GSE135838 dataset from the Gene Expression Omnibus (GEO) database and performed comparative analysis of differentially expressed genes (DEGs) using the AlzData database to identify co-expressed DEGs. Functional and protein-protein interaction (PPI) network analyses were used to identify hub genes and their associated molecular mechanisms. Animal experiments were conducted to validate the role of the central gene C5aR1 in the pathological processes of sepsis-related cognitive impairment, blood-brain barrier (BBB) disruption, and microglial activation. Co-culture experiments were performed to assess the protective effect of C5aR1 against inflammation-induced neuronal damage. In GSE135838, 25 DEGs exhibited consistent expression changes in the brain tissue of AD patients. Notably, LYZ, C5AR1, ZFP36, MPZL2, APOL4, CD163, SERPINA3, and CCL2 showed significant differential expression in the cortex and hippocampus of AD patients. KEGG pathway enrichment analysis revealed that among the 14 pathways meeting the criteria, the TNF signaling pathway demonstrated the highest significance. Key intersections of multiple GO enrichment terms included IL-6, ICAM1, CLEC4E, and PCK1. The top ten hub genes identified from the PPI network analysis included IL6, CCL2, ICAM1, CXCL1, CD163, C5AR1, SOCS3, CLEC4E, HSPB1, and HSPA1A. Pharmacological inhibition of the hub gene product C5aR1 using PMX205 improved cognitive and emotional dysfunction in CLP-induced septic mice and reduced BBB damage and microglial activation. Inhibition of C5aR1 also alleviated microglia-induced neuronal injury. In summary, the neuroimmune dysregulation caused by sepsis is correlated with potential pathological mechanisms in AD. This study provides additional molecular evidence for potential biomarkers and therapeutic targets for drug intervention in the risk of AD among sepsis survivors. - Source: PubMed
