Abstract
Recent research has sparked a discussion on the spectrum of diseases linked to the MATR3 gene associated with amyotrophic lateral sclerosis and distal myopathy with vocal cord and pharyngeal weakness (VCPDM). To date, fewer than 50 cases of VCPDM have been reported in the literature. We aim to build upon the work of previous researchers by gathering additional information about VCPDM. In this study, we present six patients from four unrelated families affected by VCPDM. Our observations include patients exhibiting both the typical phenotype associated with MATR3-related distal myopathy and rare symptomatic manifestations of the disease. Notably, two cases presented with an asymmetric scapuloperoneal phenotype, leading in one case to an initial misdiagnosis of facioscapulohumeral muscular dystrophy.

Santos JR, Park J. MATR3's Role beyond the Nuclear Matrix: From Gene Regulation to Its Implications in Amyotrophic Lateral Sclerosis and Other Diseases. Cells 2024; 13:980. [PMID: 38891112 PMCID: PMC11171696 DOI: 10.3390/cells13110980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 05/31/2024] [Accepted: 06/02/2024] [Indexed: 06/21/2024] Open
Abstract
Matrin-3 (MATR3) was initially discovered as a component of the nuclear matrix about thirty years ago. Since then, accumulating studies have provided evidence that MATR3 not only plays a structural role in the nucleus, but that it is also an active protein involved in regulating gene expression at multiple levels, including chromatin organization, DNA transcription, RNA metabolism, and protein translation in the nucleus and cytoplasm. Furthermore, MATR3 may play a critical role in various cellular processes, including DNA damage response, cell proliferation, differentiation, and survival. In addition to the revelation of its biological role, recent studies have reported MATR3's involvement in the context of various diseases, including neurodegenerative and neurodevelopmental diseases, as well as cancer. Moreover, sequencing studies of patients revealed a handful of disease-associated mutations in MATR3 linked to amyotrophic lateral sclerosis (ALS), which further elevated the gene's importance as a topic of study. In this review, we synthesize the current knowledge regarding the diverse functions of MATR3 in DNA- and RNA-related processes, as well as its involvement in various diseases, with a particular emphasis on ALS.

[PMID: 36570001 PMCID: PMC9784332 DOI: 10.7717/peerj.14552] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Accepted: 11/20/2022] [Indexed: 12/24/2022] Open
Abstract
Background A glioma is a tumor originating from glial cells in the central nervous system. Although significant progress has been made in diagnosis and treatment, most high-grade glioma patients are prone to recurrence. Therefore, molecular targeted therapy may become a new direction for adjuvant therapy in glioma. In recent years, many studies have revealed that circular RNA (circRNA) may play an important role in the occurrence and development of many tumors including gliomas. Our previous study found that the expression of hsa_circ_0008922 was up-regulated in glioma tissues upon RNA sequencing. The biological mechanism of circ_0008922 is still unreported in gliomas. Therefore, in this study, we preliminarily outlined the expression of hsa_circ_0008922 in glioma and explored its biological functions. Methods The expression of hsa_circ_0008922 in forty glioma tissues and four glioma cell lines (A172, U251, SF763 and U87) was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The correlation between hsa_circ_0008922 expression and clinicopathological features of glioma patients was evaluated by Fisher's exact test. To understand the potential function of hsa_circ_0008922 in glioma, we constructed small interfering RNA (siRNA) to hsa_circ_0008922 to downregulate its expression in glioma cell lines A172 and U251. With these hsa_circ_0008922 downregulated cells, a series of assays were carried out as follows. Cell proliferation was detected by CCK8 assay, migration and invasion were determined by wound healing assay and transwell assay, respectively. Colony formation ability was evaluated by plate clonogenic assay. Moreover, flow cytometry combined with Western blot was performed to analyze apoptosis status and the expression of apoptotic related proteins (caspase 3 and caspase 9). Finally, the possible biological pathways and potential miRNA targets of hsa_circ_0008922 were predicted by bioinformatics. Results We found that the expression of hsa_circ_0008922 in glioma tissues was 3.4 times higher than that in normal tissues. The expression of has_circ_0008922 was correlated with WHO tumor grade. After down-regulating the expression of hsa_circ_0008922, malignant biological behavior of glioma cells was inhibited, such as cell proliferation, colony formation, migration, and invasion. At the same time, it also induced apoptosis of glioma cells. Predicted analysis by bioinformatics demonstrated that hsa_circ_0008922 may be involved in tumor-related pathways by acting as a molecular sponge for multiple miRNAs (hsa-let-7e-5p, hsa-miR-506-5p, hsa-let-7b-5p, hsa-let-7c-5p and hsa-let-7a-5p). Finally, we integrated our observation to build a circRNA-miRNA-mRNA predictive network.

Expanding the Phenotypic Spectrum of Vocal Cord and Pharyngeal Weakness With Distal Myopathy due to the p.S85C MATR3 Mutation. Neurol Genet 2022; 8:e200006. [PMID: 35812165 PMCID: PMC9258980 DOI: 10.1212/nxg.0000000000200006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 05/04/2022] [Indexed: 11/16/2022]
Abstract
Objectives The c.254C>G (p.S85C) MATR3 variant causes vocal cord and pharyngeal weakness with distal myopathy (VCPDM), which is characterized by progressive, asymmetric, predominantly distal muscle weakness, dysphonia, dysphagia, and respiratory impairment. Herein, we describe an Italian patient who harbored the p.S85C MATR3 variant and showed a composite phenotype of VCPDM and sensorimotor polyneuropathy. Methods The proband underwent neurologic evaluation, muscular MRI of the lower limbs, neurophysiologic assessment, muscle biopsy, and spirometry. After excluding common acquired and genetic causes of sensorimotor polyneuropathy, a larger group of genes involved in inherited forms of neuropathy, distal myopathy, and motor neuron disorders were analyzed by next-generation sequencing targeted panels. Results The patient, affected by progressive distal muscle weakness and hypotrophy, myalgias, dysphonia, dysphagia, respiratory impairment, and sensory abnormalities, harbored the heterozygous c.254C>G (p.S85C) MATR3 substitution. Neurophysiologic assessment revealed a severe sensorimotor polyneuropathy. Variation of fiber size, central nuclei, and nonrimmed vacuoles were evident at muscle biopsy. Discussion This finding extends the MATR3-associated VCPDM phenotypic spectrum and suggests considering MATR3 analysis in suspected congenital polyneuropathies with odd features, including dysphonia, dysphagia, and respiratory insufficiency.
