TAR DNA-Binding protein 43 accumulation in protein aggregate myopathies.
Protein aggregate myopathies, including myofibrillar myopathies and sporadic inclusion body myositis (sIBM), are characterized by abnormal protein aggregates composed of various muscular and ectopic proteins. Previous studies have shown the crucial role ofdysregulated transcription factors such as neuron-restrictive silencerfactor in the expression of aberrant proteins in myotilinopathies. Here...
متن کاملThe C-Terminal TDP-43 Fragments Have a High Aggregation Propensity and Harm Neurons by a Dominant-Negative Mechanism
TAR DNA binding protein 43 KD (TDP-43) is an essential gene that regulates gene transcription, mRNA splicing and stability. In amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), two fatal neurodegenerative diseases, TDP-43 is fragmented, generating multiple fragments that include the C-terminal fragment of ∼25 KD. The role of these fragments in the pathogenesis of ALS and FT...
متن کاملEnrichment of C-terminal fragments in TAR DNA-binding protein-43 cytoplasmic inclusions in brain but not in spinal cord of frontotemporal lobar degeneration and amyotrophic lateral sclerosis.
TAR DNA-binding protein (TDP-43) has been recently described as a major pathological protein in both frontotemporal dementia with ubiquitin-positive inclusions (FTLD-U) and amyotrophic lateral sclerosis. However, little is known about the relative abundance and distribution of different pathological TDP-43 species, which include hyperphosphorylated, ubiquitinated, and N-terminally cleaved TDP-4...
متن کاملTAR-DNA binding protein 43 in Pick disease.
Pick disease (PiD) is a frontotemporal dementia characterized by frontal and temporal atrophy, neuronal loss, gliosis, ballooned neurons that are positive for alpha-B crystallin and neurofilament, and the presence of tau- and ubiquitin-positive Pick bodies. TAR-DNA binding protein 43 (TDP-43) has been found to be a component of ubiquitinated inclusions in other neurodegenerative diseases, inclu...
متن کاملCaspase-cleaved TAR DNA-binding protein-43 in Pick's disease.
The hyperphosphorylation and proteolytic modification of the TAR DNA binding protein-43 (TDP-43) is a key finding in a number of neurodegenerative diseases including frontotemporal dementia with ubiquitin-positive inclusions (FTLD-U), amyotrophic lateral sclerosis (ALS), and most recently Alzheimer's disease (AD). To examine whether proteolytic modifications of TDP-43 is a relevant finding in P...
