Intermittent Theta Burst Stimulation Attenuates Cognitive Deficits and Alzheimer's Disease-Type Pathologies via ISCA1-Mediated Mitochondrial Modulation in APP/PS1 Mice. Neurosci Bull 2024; 40:182-200. [PMID: 37578635 PMCID: PMC10838862 DOI: 10.1007/s12264-023-01098-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 04/28/2023] [Indexed: 08/15/2023] Open
Abstract
Intermittent theta burst stimulation (iTBS), a time-saving and cost-effective repetitive transcranial magnetic stimulation regime, has been shown to improve cognition in patients with Alzheimer's disease (AD). However, the specific mechanism underlying iTBS-induced cognitive enhancement remains unknown. Previous studies suggested that mitochondrial functions are modulated by magnetic stimulation. Here, we showed that iTBS upregulates the expression of iron-sulfur cluster assembly 1 (ISCA1, an essential regulatory factor for mitochondrial respiration) in the brain of APP/PS1 mice. In vivo and in vitro studies revealed that iTBS modulates mitochondrial iron-sulfur cluster assembly to facilitate mitochondrial respiration and function, which is required for ISCA1. Moreover, iTBS rescues cognitive decline and attenuates AD-type pathologies in APP/PS1 mice. The present study uncovers a novel mechanism by which iTBS modulates mitochondrial respiration and function via ISCA1-mediated iron-sulfur cluster assembly to alleviate cognitive impairments and pathologies in AD. We provide the mechanistic target of iTBS that warrants its therapeutic potential for AD patients.

Animal Model Exp Med 2023; 6:155-167. [PMID: 37140997 PMCID: PMC10158949 DOI: 10.1002/ame2.12318] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 03/14/2023] [Indexed: 05/05/2023] Open
Abstract
BACKGROUND Multiple mitochondrial dysfunction syndromes (MMDS) are rare mitochondrial diseases caused by mutation of mitochondrial iron-sulfur cluster synthesis proteins. This study established a rat model simulating MMDS5 disease in the nervous system to investigate its pathological features and neuronal death. METHODS We generated neuron-specific Isca1 knockout rat (Isca1flox/flox -NeuN-Cre) using CRISPR-Cas9 technology. The brain structure changes of CKO rats were studied with MRI, and the behavior abnormalities were analyzed through gait analysis and open field tests, Y maze tests and food maze tests. The pathological changes of neurons were analyzed through H&E staining, Nissl staining, and Golgi staining. Mitochondrial damage was assessed by TEM, western blot and ATP assay, and the morphology of neurons was assessed by WGA immunofluorescence to detect the death of neurons. RESULTS This study established the disease model of MMDS5 in the nervous system for the first time, and found that after Isca1 loss, the rats suffered from developmental retardation, epilepsy, memory impairment, massive neuronal death, reduced number of Nissl bodies and dendritic spines, mitochondrial fragmentation, cristae fracture, reduced content of respiratory chain complex protein, and reduced production of ATP. Isca1 knockout caused neuronal oncosis. CONCLUSIONS This rat model can be used to study the pathogenesis of MMDS. In addition, compared with human MMDS5, the rat model can survive up to 8 weeks of age, effectively extending the window of clinical treatment research, and can be used for the treatment of neurological symptoms in other mitochondrial diseases.

Abstract
The importance of mitochondria in mammalian cells is widely known. Several biochemical reactions and pathways take place within mitochondria: among them, there are those involving the biogenesis of the iron–sulfur (Fe-S) clusters. The latter are evolutionarily conserved, ubiquitous inorganic cofactors, performing a variety of functions, such as electron transport, enzymatic catalysis, DNA maintenance, and gene expression regulation. The synthesis and distribution of Fe-S clusters are strictly controlled cellular processes that involve several mitochondrial proteins that specifically interact each other to form a complex machinery (Iron Sulfur Cluster assembly machinery, ISC machinery hereafter). This machinery ensures the correct assembly of both [2Fe-2S] and [4Fe-4S] clusters and their insertion in the mitochondrial target proteins. The present review provides a structural and molecular overview of the rare diseases associated with the genes encoding for the accessory proteins of the ISC machinery (i.e., GLRX5, ISCA1, ISCA2, IBA57, FDX2, BOLA3, IND1 and NFU1) involved in the assembly and insertion of [4Fe-4S] clusters in mitochondrial proteins. The disease-related missense mutations were mapped on the 3D structures of these accessory proteins or of their protein complexes, and the possible impact that these mutations have on their specific activity/function in the frame of the mitochondrial [4Fe-4S] protein biogenesis is described.

Novel rat model of multiple mitochondrial dysfunction syndromes (MMDS) complicated with cardiomyopathy. Animal Model Exp Med 2021; 4:381-390.

Abstract
Background Multiple mitochondrial dysfunction syndromes (MMDS) presents as complex mitochondrial damage, thus impairing a variety of metabolic pathways. Heart dysplasia has been reported in MMDS patients; however, the specific clinical symptoms and pathogenesis remain unclear. More urgently, there is a lack of an animal model to aid research. Therefore, we selected a reported MMDS causal gene, Isca1, and established an animal model of MMDS complicated with cardiac dysplasia. Methods The myocardium-specific Isca1 knockout heterozygote (Isca1 HET) rat was obtained by crossing the Isca1 conditional knockout (Isca1 cKO) rat with the α myosin heavy chain Cre (α-MHC-Cre) rat. Cardiac development characteristics were determined by ECG, blood pressure measurement, echocardiography and histopathological analysis. The responsiveness to pathological stimuli were observed through adriamycin treatment. Mitochondria and metabolism disorder were determined by activity analysis of mitochondrial respiratory chain complex and ATP production in myocardium. Results ISCA1 expression in myocardium exhibited a semizygous effect. Isca1 HET rats exhibited dilated cardiomyopathy characteristics, including thin-walled ventricles, larger chambers, cardiac dysfunction and myocardium fibrosis. Downregulated ISCA1 led to deteriorating cardiac pathological processes at the global and organizational levels. Meanwhile, HET rats exhibited typical MMDS characteristics, including damaged mitochondrial morphology and enzyme activity for mitochondrial respiratory chain complexes Ⅰ, Ⅱ and Ⅳ, and impaired ATP production. Conclusion We have established a rat model of MMDS complicated with cardiomyopathy, it can also be used as model of myocardial energy metabolism dysfunction and mitochondrial cardiomyopathy. This model can be applied to the study of the mechanism of energy metabolism in cardiovascular diseases, as well as research and development of drugs.

A Review of Multiple Mitochondrial Dysfunction Syndromes, Syndromes Associated with Defective Fe-S Protein Maturation. Biomedicines 2021; 9:biomedicines9080989. [PMID: 34440194 PMCID: PMC8393393 DOI: 10.3390/biomedicines9080989] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 08/03/2021] [Accepted: 08/06/2021] [Indexed: 11/25/2022] Open
Abstract
Mitochondrial proteins carrying iron-sulfur (Fe-S) clusters are involved in essential cellular pathways such as oxidative phosphorylation, lipoic acid synthesis, and iron metabolism. NFU1, BOLA3, IBA57, ISCA2, and ISCA1 are involved in the last steps of the maturation of mitochondrial [4Fe-4S]-containing proteins. Since 2011, mutations in their genes leading to five multiple mitochondrial dysfunction syndromes (MMDS types 1 to 5) were reported. The aim of this systematic review is to describe all reported MMDS-patients. Their clinical, biological, and radiological data and associated genotype will be compared to each other. Despite certain specific clinical elements such as pulmonary hypertension or dilated cardiomyopathy in MMDS type 1 or 2, respectively, nearly all of the patients with MMDS presented with severe and early onset leukoencephalopathy. Diagnosis could be suggested by high lactate, pyruvate, and glycine levels in body fluids. Genetic analysis including large gene panels (Next Generation Sequencing) or whole exome sequencing is needed to confirm diagnosis.
