To quantitatively survey selective resistance, we studied extensive neuromuscular autopsies of Type I SMA patients and age-matched controls. We found highly divergent degrees of degeneration of neighboring motor units, even within individual cranial nerves or a single anatomical area such as the neck. Examination of a Type I SMA patient maintained on life support for 17 years found that most muscles were atrophied, but the diaphragm was strikingly preserved. Nevertheless, some resistant human muscles with preserved morphology displayed nearly complete conversion to slow Type I myofibers. Remarkably, a similar pattern of selective resistance was observed in the SMNΔ7 mouse model. Overall, differential motor unit vulnerability in human Type I SMA suggests the existence of potent, motor unit-specific disease modifiers. Mechanisms that confer selective resistance to SMA may represent therapeutic targets independent of the SMN protein, particularly in patients with neuromuscular weakness refractory to current treatments.</p>","PeriodicalId":13070,"journal":{"name":"Human molecular genetics","volume":" ","pages":"347-367"},"PeriodicalIF":3.1,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11811418/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142846572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We employed a latent causal variable model and Mendelian randomization (MR) analysis to infer causal relationships. Colocalization analysis and conditional/conjunctional false discovery rate (condFDR/conjFDR) were used to identify genomic overlaps and shared risk loci. Two-step MR analysis was utilized to identify potential mediators. We observed a strong positive genomic correlation between NAFLD and T2D (rg = 0.652, P = 5.67 × 10-6) and identified tissue-specific transcriptomic correlations in the pancreas, liver, skeletal muscle, subcutaneous adipose, and blood. Genetic enrichment was observed in NAFLD conditional on associations with T2D and vice versa, indicating significant polygenic overlaps. We found robust evidence for the causal effect of NAFLD on T2D, particularly insulin-related T2D, rather than vice versa. Colocalization analysis identified shared genomic regions between NAFLD and T2D, including GCKR, FTO, MAU2-TM6SF2, and PNPLA3-SAMM50.

Subsequently, through screening and analysis of the PPI network constructed by the Search Tool for the Retrieval of Interacting Genes (STRING) database, we obtained 3 CPSP-related hub genes (CD163, MMP9, and ARG1). They were all highly expressed in the IS group, exhibiting good diagnostic performance, with area under curve (AUC) value > 0.85. The immune-related analysis demonstrated that the infiltration levels of various immune cells in the IS group and the normal group were substantially different. In addition, by utilizing some online websites, we not only predicted some microRNAs (miRNAs) and transcription factors (TFs) that may target hub genes but also mined small molecular drugs that may target differentially expressed genes (DEGs) in IS. In conclusion, this project first investigated the role of CPSP-related genes in IS and identified 3 hub genes. At the same time, we predicted some miRNAs, TFs, and candidate drugs that may target hub genes. Our research uncovered the potential mechanism of CPSP-related genes in IS from multiple perspectives.

In our previous high-throughput sequencing, we identified an 11.32-fold increase in miR-129-5p expression in β-thalassemia patients. However, the regulatory mechanisms of miR-129-5p in the context of erythroid differentiation remain to be elucidated. Our study aimed to elucidate the role of miR-129-5p in γ-globin regulation and erythropoiesis. We measured miR-129-5p levels in peripheral blood from β-thalassemia major and intermedia patients. Fluorescence in situ hybridization, dual-luciferase reporter assays, miRNA pull down assays and western blot analyses were conducted to examine the effects of miR-129-5p on γ-globin expression and BCL11A repression. Cell proliferation, apoptosis, and erythroid differentiation were assessed using cell counting kit-8, Wright-Giemsa, and benzidine staining, and flow cytometry assays. The expression levels of miR-129-5p were significantly elevated in β-thalassemia patients and positively correlated with γ-globin synthesis while negatively correlating with liver damage. miR-129- 5p enhanced γ-globin gene expression in K562 and HUDEP-2 cells by effectively repressing BCL11A. Overexpression of miR-129-5p inhibited cell proliferation, induced cell cycle arrest at the G1/G0 phase, promoted apoptosis and stimulated erythroid differentiation and maturation. Conversely, inhibition of miR-129-5p produced opposite cellular effects. miR-129-5p acts as a positive regulator of erythroid differentiation and γ-globin synthesis.

We found that RNAi-mediated ZNF850 downregulation in DM1-iPSCs significantly reduced the repeat expansion and resulting instability. In adult skeletal muscle tissue of DM1 patients, ZNF850 expression levels were positively correlated with the repeat size. Furthermore, we found that ZNF850 protein can bind to the expanded CTG repeat sequence, and is located in proximity to MutSβ components.

The all human-derived BhB-BhB transgene (4.9 kb) was as good as our previous miniXIST, suggesting that these domains are the human equivalent of the mouse PID region. A PID-PID transgene (5.8 kb) was not statistically different from Full XIST and could be potentially used for chromosome therapy. Adding BhB to PID (BhB-PID, 5.4 kb) had an intermediate efficacy compared to the other two transgenes, suggesting that the most important component for silencing and heterochromatic mark recruitment is the number of CCC motifs, not the species of origin.

Functional genetic loci can affect transcriptional and post-transcriptional phenotypes that may contribute to disease pathology.

The alternative pathway (AP) of complement has been linked to the pathogenesis of AMD. In particular, rare variants (RVs) in the complement factor I (CFI) gene encoding the Factor I (FI) protein confer increased AMD risk. The prevalence of CFI RVs are well characterised in European AMD, however little is known about other populations. The Finnish population underwent genetic restriction events which have skewed allele frequencies in unexpected ways. A series of novel or enriched CFI RVs were identified in individuals with dry AMD from the Finnish Biobank Cooperative (FINBB), but the relationship between these genotypes and contribution to disease was unclear. Understanding how RVs impact the ability of FI to regulate the complement system is important to inform mechanistic understanding for how different genotypes contribute to disease development. To explore this a series of in vitro assays were used to functionally characterise the protein products of 3 CFI RVs enriched in FINBB dry AMD, where no prior data were available. The G547R variant resulted in almost complete loss of both classical pathway and AP regulatory potential. The c.982 g>a variant encoding G328R FI perturbed an exon splice enhancer site which resulted in exon skipping and a premature stop codon in vitro and low levels of FI in vivo. Despite detailed analysis no defect in levels or function was demonstrated in T107A. Functional characterization of all Finnish CFI RVs in the cohort allowed us to demonstrate that in Finnish dry AMD, collectively the type 1 CFI RVs (associated with FI haploinsufficiency) were significantly enriched with odds ratio (ORs) of 72.6 (95% confidence interval; CI 16.92 to 382.1).
