MECANISMO DE DOENÇA

Spinocerebellar ataxia 7

Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA7 belongs to the autosomal dominant cerebellar ataxias type II (ADCA II) which are characterized by cerebellar ataxia with retinal degeneration and pigmentary macular dystrophy.

Integrated Plasma and Glial Cell Evidence Indicates a Functional Role for hsa-miR-342-5p in Spinocerebellar Ataxia Type 7 and Its Potential Use as a Biomarker.

International journal of molecular sciences2026 Jan 09

Spinocerebellar ataxia type 7 (SCA7) is a neurodegenerative disease characterized by cerebellar ataxia and retinal degeneration, caused by an abnormal expansion of CAG repeats at the ATXN7 gene. Disease onset and progression vary among patients, underscoring the need for novel tools to improve disease monitoring. Circulating miRNAs represent a promising prognostic tool, due to their minimally invasive sampling and high stability. The aim of this study was to assess the expression of twelve circulating miRNAs associated with neurodegeneration in plasma samples from SCA7 patients and in an inducible SCA7 glial cell model. A comparison of SCA7 patients and controls revealed that nine miRNAs exhibited significantly higher expression. Furthermore, comparison of patients with different SCA7 phenotypes to controls revealed that most miRNAs were overexpressed in plasma from early-onset patients corresponding to the clinically more severe phenotype. Regarding the cell model, we identified three miRNAs that were dysregulated; however, only hsa-miR-342-5p displayed a pattern consistent with that observed in the plasma of patient. Our findings indicate that hsa-miR-342-5p is differentially expressed in the plasma of patients and the SCA7 cellular model, implying that it can serve as a biomarker and facilitate the identification of novel processes involved in SCA7.

Evaluating Glial Fibrillary Acidic Protein and Neurofilament Light as Potential Biomarkers for Spinocerebellar Ataxia 7.

International journal of molecular sciences2025 May 24

Spinocerebellar ataxia type 7 (SCA7), a rare form of ataxia, possesses a wide phenotypic spectrum ranging from classic ataxic symptoms to blindness, multiorgan failure, cardiomyopathy, and early death among younger age groups. Biomarkers associated with disease progression and severity could aid in disease prognostication. We evaluated the utility of glial fibrillary acidic protein (GFAP) and neurofilament light (NfL) in distinguishing patients with SCA7 from healthy controls and estimating patient prognosis. GFAP and NfL levels were measured in 23 plasma and 20 cerebrospinal fluid (CSF) samples from asymptomatic (N = 3) and symptomatic SCA7 participants (N = 10) and from healthy controls (N = 8). GFAP concentrations were elevated in the plasma (82.7 pg/mL) and CSF (9318 pg/mL) of patients with SCA7 compared to controls (plasma: 48.0 pg/mL; CSF: 89,056 pg/mL). Similarly, NfL plasma (21.6 pg/mL) and CSF (2615.0 pg/mL) levels were also significantly upregulated in SCA7 compared to controls (plasma: 8.2 pg/mL; CSF: 414.6 pg/mL). Higher levels of NfL, but not of GFAP, significantly discriminated symptomatic SCA7 patients from controls (area under de curve, AUC: 0.898, p = 0.0059, in plasma, and AUC: 1.0, p = 0.0012, in CSF). The levels of both biomarkers increased overtime, with plasma NfL levels strongly associated with a worse score in the scale for the assessment and rating of ataxia (SARA) (Spearman r: 0.8354, p = 0.0007; regression analysis: β: 0.021, 95% CI: 0.008-0.035, p = 0.0048). These findings suggest that NfL could serve as a valuable biomarker for monitoring disease progression and prognosis in SCA7 patients.

Multi-omic insights into molecular mechanism and therapeutic targets in spinocerebellar ataxia type 7.

Molecular therapy. Nucleic acids2025 Mar 11

Recent advances in molecular science have significantly enlightened our mechanistic understanding of spinocerebellar ataxia type 7. To further close remaining gaps, we performed a multi-omics analysis using SCA7266Q/5Q mice. Entire brain tissue samples were collected from 12-week-old mice, and RNA sequencing, methylation analysis, and proteomic analysis were performed. Results were integrated to identify genes with identical trends in expression across all three analyses. Data from RNA sequencing and methylation analysis revealed 58 significantly hypomethylated-upregulated genes and 62 hypermethylated-downregulated genes, mostly enriched in GO terms of regulation of axonogenesis, channel activity, and monoamine signaling. In the proteomic analysis, 211 upregulated and 281 downregulated DEPs associated mostly with immune response and cellular mobility were identified. Two genes, Fam107b and Tph2, showed differential expressions in both transcriptomic and proteomic analyses. Findings were validated in RT-qPCR as well as open data source analysis. Our study is the first to perform multi-omics analysis in SCA7 mice and will serve as an important reference for future studies.

In Silico Analysis of miRNA-Regulated Pathways in Spinocerebellar Ataxia Type 7.

Current issues in molecular biology2025 Mar 02

Spinocerebellar ataxia type 7 (SCA7) is an inherited neurodegenerative disease characterized by cerebellar ataxia and retinal degeneration, caused by an abnormal expansion of the CAG trinucleotide in the coding region of the ATXN7 gene. Currently, in silico analysis is used to explore mechanisms and biological processes through bioinformatics predictions in various neurodegenerative diseases. Therefore, the aim of this study was to identify candidate human gene targets of four miRNAs (hsa-miR-29a-3p, hsa-miR-132-3p, hsa-miR-25-3p, and hsa-miR-92a-3p) involved in pathways that could play an important role in SCA7 pathogenesis through comprehensive in silico analysis including the prediction of miRNA target genes, Gen Ontology enrichment, identification of core genes in KEGG pathways, transcription factors and validated miRNA target genes with the mouse SCA7 transcriptome data. Our results showed the participation of the following pathways: adherens junction, focal adhesion, neurotrophin signaling, endoplasmic reticulum processing, actin cytoskeleton regulation, RNA transport, and apoptosis and dopaminergic synapse. In conclusion, unlike previous studies, we highlight using a bioinformatics approach the core genes and transcription factors involved in the different biological pathways and which ones are targets for the four miRNAs, which, in addition to being associated with neurodegenerative diseases, are also de-regulated in the plasma of patients with SCA7.

Retinal degeneration in spinocerebellar ataxia type 7: an overview of the current knowledge.

Arquivos brasileiros de oftalmologia2025

Spinocerebellar ataxia type 7 is a form of spinocerebellar ataxia, which is a clinically and genetically heterogeneous group of rare inherited neurodegenerative disorders. Among the spinocerebellar ataxias, the association between cerebellar ataxia and cone-rod retinal dystrophy is a strong indicator of spinocerebellar ataxia type 7. Spinocerebellar ataxia type 7 cone-rod dystrophy is a progressive, disabling, and incurable form of hereditary retinopathy. However, the field of genetics has markedly progressed in the last decades, which resulted in improved understanding of multiple aspects of spinocerebellar ataxia type 7 retinal degeneration and the emergence of new modalities of genetic therapies for other types of retinal dystrophies. This study aimed to evaluate the current knowledge on spinocerebellar ataxia type 7 retinal degeneration, including genetics and molecular mechanisms as well as their implications in pathogenesis, clinical manifestations, and potential therapeutic strategies.
