The instant disclosure describes an electrophoretic procedure capable of resolving and isolating ultra high molecular weight (MW) protein aggregates from nerve tissue. The procedure is based on the use of composite agarose-polyacrylamide gel electrophoresis (CAPAGE) and resolves proteins and protein aggregates over the range of from approximately 225 kDa to approximately 30,000 kDa. Triton X-100 precipitation is used to obtain a cytoskeleton protein fraction that is subsequently resuspended and subjected to gel electrophoresis. This method demonstrates that a protein aggregate of approximately 30,000 kDa is characteristic of normal murine spinal cord tissue and that the amount of said protein aggregate is increased in spinal cord homogenate obtained from transgenic mice bearing copies of a mutant human gene characteristic of familial amyotrophic lateral sclerosis. This method for separating nerve tissue ultra high MW cytoskeleton protein aggregates can prove useful in a variety of future biophysical and pharmacological studies related to the etiologies of Charcot-Marie-Tooth disease, Alzheimer's disease, Parkinson's disease, diseases based on expansions in tandem DNA repeats, spinal muscular atrophy, Friedreich's ataxia, giant axon neuropathy, juvenile ceroid-lipofuscinosis, amyotrophic lateral sclerosis, diabetic polyneuropathy and Down's syndrome.

The present invention relates to a method for the screening of a therapeutic agent for Charcot-Marie-Tooth disease (CMT) using induced pluripotent stem cells and motor neurons differentiated therefrom. Particularly, the present inventors prepared induced pluripotent stem cells from the human fibroblasts originated from CMT patient. When the motor neurons differentiated from the said induced pluripotent stem cells are used for the screening of a therapeutic agent for Charcot-Marie-Tooth disease, the pharmaceutical effect of the therapeutic agent candidates can be easily evaluated during the screening. In addition, by the method to prepare the induced pluripotent stem cells, autologous motor neurons which are usable for the screening of a patient-specific therapeutic agent and the patient-specific treatment can be prepared.

As with many human physiological systems, issues within the central nervous system can arise for individuals leading to a variety of neurological disorders including, but not limited to, Charcot-Marie-Tooth disease, Alzheimer' disease, Parkinson's disease, multiple sclerosis, myasthenia gravis, demyelination, and axonal degeneration. However, culture devices presently provide researchers with limitations in their research. Embodiments of the invention aims to address these various limitations and allow studies, methods and screenings which cannot be performed with prior art culture devices. These include reducing manufacturing complexity, volumes of pharmaceuticals and cells required, allowing use in fields other than neurobiology, improved adhesion within the desired micro-channel regions of the devices, and increasing cell survival in cultures. Accordingly, microfluidic devices comprising a connecting chamber and micro-channel having the same depth which prevents hydrostatic pressure, end walls of the connecting chamber and micro-channel arrays having a high angle relative to the fluid flow direction for supporting culturing and topside of the connecting chamber that has been profiled in order to improve the adhesion of cells is provided.

Provided are compositions and methods for the treatment of mutant glycyl-tRNA synthetase (GlyRS)-associated diseases, such as Charcot-Marie-Tooth (CMT) diseases, and related compositions and methods for diagnostic, drug discovery, and research applications. Also provided are mutant glycyl-tRNA synthetases and uses thereof.

Methods are described for screening a subject for risk of Charcot-Marie-Tooth Disease Type 2A or for diagnosing Charcot-Marie-Tooth disease or a predisposition for developing Charcot-Marie-Tooth disease in a subject, by detecting the presence or absence of a mutation in the mitofusin gene in a biological sample collected from the subject. Methods are also described for detecting the presence of a genetic polymorphism associated with Charcot-Marie-Tooth Disease Type 2A in a sample of patient nucleic acid, by amplifying a mitofusin gene sequence in the patient nucleic acid to produce an amplification product; and identifying the presence of a Charcot-Marie-Tooth Disease Type 2A associated polymorphism in the amplification product.

The invention broadly relates to the use of the Active in the causal treatment of a disease caused by axonal demyelination, in which the Active maintains the integrity of myelination (for example by promoting remyelination, and / or preventing demyelination, of the axonal sheaths). The invention is particularly directed to the causal treatment of CNS demyelination diseases, for example MS, especially primary progressive MS and / or relapse remitting MS, and PNS demyelination diseases, for example Charcot-Marie-Tooth Disease. The Active of the invention may be suitably administered when a patient is in relapse (i.e. upon relapse), and be continued while the patient is in relapse, with a view to attenuating the severity of the relapse, and / or accelerating disease remission. Alternatively, the Active may be administered continuously with a view to prolonging the remission period, and / or attenuating the severity of the relapse, and / or preventing relapse. The invention also relates to the use of the Active as a treatment for symptoms of demyelination disease, especially MS, selected from vision deficits, motor control deficits, and sensation deficits.

The present invention relates to a HSP27 mutation (S135F) mediated Charcot-Marie-Tooth disease (CMT) animal model. Particularly, the vector expressing mutant HSP27 protein wherein the 135th serine is substituted with phenylalanine has been injected in the mouse zygote and then the mouse harboring the expression vector was selected. The selected mouse was confirmed to display Charcot-Marie-Tooth disease phenotype, so that the animal model was expected to be efficiently used for the evaluation of the effect of Charcot-Marie-Tooth disease treating material candidates.

Compared with SEQ ID NO:1, the isolated nucleic acid for coding the AMSH mutant comprises c.364A>G mutation. By detecting whether the new mutant exists in the biological sample or not, whether the biological sample is predisposed to charcot-marie-tooth disease or not can be effectively detected.
