Identification of Genetic Modifiers of TDP-43 Neurotoxicity in Drosophila
Cytosolic aggregation of the nuclear RNA-binding protein TDP-43 is a histopathologic signature of degenerating neurons in amyotrophic lateral sclerosis (ALS), and mutations in the TARDBP gene encoding TDP-43 cause dominantly inherited forms of this condition. To understand the relationship between TDP-43 misregulation and neurotoxicity, we and others have used Drosophila as a model system, in w...
متن کاملWild-type and A315T mutant TDP-43 exert differential neurotoxicity in a Drosophila model of ALS.
The RNA-binding protein TDP-43 has been linked to amyotrophic lateral sclerosis (ALS) both as a causative locus and as a marker of pathology. With several missense mutations being identified within TDP-43, efforts have been directed towards generating animal models of ALS in mouse, zebrafish, Drosophila and worms. Previous loss of function and overexpression studies have shown that alterations ...
متن کاملRNA binding mediates neurotoxicity in the transgenic Drosophila model of TDP-43 proteinopathy.
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive and selective loss of motor neurons. The discovery of mutations in the gene encoding an RNA-binding protein, TAR DNA-binding protein of 43 kD (TDP-43), in familial ALS, strongly implicated abnormalities in RNA processing in the pathogenesis of ALS, although the mechanisms whereby TDP-43 leads to neu...
متن کاملDrosophila Answers to TDP-43 Proteinopathies
Initially implicated in the pathogenesis of CFTR and HIV-1 transcription, nuclear factor TDP-43 was subsequently found to be involved in the origin and development of several neurodegenerative diseases. In 2006, in fact, it was reported for the first time the cytoplasmic accumulation of TDP-43 in ubiquitin-positive inclusions of ALS and FTLD patients, suggesting the presence of a shared underly...
متن کاملA Drosophila model for TDP-43 proteinopathy.
Neuropathology involving TAR DNA binding protein-43 (TDP-43) has been identified in a wide spectrum of neurodegenerative diseases collectively named as TDP-43 proteinopathy, including amyotrophic lateral sclerosis (ALS) and frontotemporal lobar dementia (FTLD). To test whether increased expression of wide-type human TDP-43 (hTDP-43) may cause neurotoxicity in vivo, we generated transgenic flies...
