FIG4 is a phosphatase that regulates intracellular vesicle trafficking along the endosomal-lysosomal pathway. Mutations of FIG4 lead to the development of Charcot-Marie-Tooth disease type 4J and amyotrophic lateral sclerosis (ALS). Moreover, ALS-associated proteins (transactivation response DNA
The microtubule-associated protein Tau, generated by the MAPT gene is involved in dozens of neurodegenerative conditions ("tauopathies"), including Alzheimer's disease (AD) and frontotemporal lobar degeneration/frontotemporal dementia (FTLD/FTD). The pre-mRNA of MAPT is well studied and its aberrant
Accumulation of toxic protein assemblies and damaged mitochondria are key features of neurodegenerative diseases, which arise in large part from clearance defects in the Macroautophagy/autophagy-lysosome system. The autophagy cargo receptor SQSTM1/p62 plays a major role in the clearance of
An abnormally expanded GGGGCC repeat in C9ORF72 is the most frequent causal mutation associated with amyotrophic lateral sclerosis (ALS)/frontotemporal lobar degeneration (FTLD). Both gain-of-function (gf) and loss-of-function (lf) mechanisms have been involved in C9ORF72 related ALS/FTLD. The gf
The intronic hexanucleotide expansion in the C9orf72 gene is one of the leading causes of frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS), two devastating neurodegenerative diseases. C9orf72 forms a heterodimer with SMCR8 (Smith-Magenis syndrome chromosome region,
Phosphatase and tensin homolog (PTEN) regulates synaptic density in development; however, whether PTEN also regulates synapse loss in a neurodegenerative disorder such as frontotemporal lobar degeneration with Tau deposition (FTLD-Tau) has not been explored. Here, we found that pathological Tau
Aging is characterized by progressive memory decline that can lead to dementia when associated with neurodegeneration. Here, we show in mice that aging-related memory decline involves defective biogenesis of microRNAs (miRNAs), in particular miR-183/96/182 cluster, resulting from increased protein
Amyotrophic lateral sclerosis (ALS) is increasingly recognized to be a syndromic disorder in which the degeneration of motor neurons is frequently accompanied by a range of syndromes reflective of frontotemporal dysfunction, including a behavioural or cognitive syndrome, a dysexecutive syndrome or a
