Human TARDBP ELISA Kit for Sandwich ELISA - ABIN511634
Thakur, Sharma, Prabhakar, Gupta, Anand: Revisiting the dilution factor as vital parameter for sensitivity of ELISA assay in CSF and Plasma. in Annals of neurosciences 2015
ALS (show IGFALS ELISA Kits)-mutant linked TDP-43 mutations expressed at moderate levels in a pattern mimicking endogenous TDP-43 also cause toxicity in a non-cell autonomous manner. Eliminating mutant TDP-43Q331K synthesis in a proportion of motor neurons delayed disease onset, reduced aberrant nuclear morphology in those neurons at early disease stages, and almost eliminated age-dependent accelerated death of those motor neurons.
Study reports that cryptic exon incorporation occurred not only in Alzheimer' disease brains exhibiting TDP-43 pathology, but also in neurons lacking cytoplasmic inclusion but exhibiting nuclear clearance of TDP-43.
Acetylation of the protein triggers TDP-43 pathology in cultured cells and mouse skeletal muscle, which can be cleared through an HSF1 (show HSF1 ELISA Kits)-dependent chaperone mechanism that disaggregates the protein.
These studies showed that physiological oligomerization of TDP-43 is mediated through its N-terminal domain, which forms functional and dynamic oligomers antagonizing pathologic aggregation.
Expression of PFN1 (show PFN1 ELISA Kits) mutants induces accumulation of TDP-43, and promotes conversion of normal TDP-43 into an abnormal form. These results provide new insight into the mechanisms of TDP-43 proteinopathies and other diseases associated with amyloid-like protein deposition.
Study reports the altered expression and/or mislocalization of the TAR-DNA binding protein 43 (TDP-43) in both niemann-pick disease type C mouse and in a human neuronal model of the disease. Results extend the importance of the role of TDP-43 in neurodegenerative disease and further highlight the need to prioritize the targeting of this protein to develop novel therapeutic strategies.
This study demonstrated that increased rates of TDP-43-associated hippocampal atrophy might occur at least 10 years before death in patient with Alzheimer disease.
Authors observed impaired levels of glutathione (downstream Nrf2 (show GABPA ELISA Kits) antioxidant) in TDP-43M337V patient fibroblasts and astrocyte cultures from TDP-43Q331K mice, indicative of elevated oxidative stress and failure of some upregulated antioxidant genes to be translated into protein.
removing the human orthologs of Hrb27c (DAZAP1 (show DAZAP1 ELISA Kits)) in human neuronal cell lines can correct several pre-mRNA splicing events altered by TDP-43 depletion
TDP-43 suppressed tau expression by promoting its mRNA instability through the UG repeats of its 3-UTR (show UTS2R ELISA Kits). The C-terminal region of TDP-43 was required for this function.The level of TDP-43, which is decreased in AD brains, was found to correlate negatively with the tau level in human brain.
results suggest that regulation of the U6 snRNA expression level by TDP-43 is a key factor in the increase in cell death upon TDP-43 loss-of-function
this study shows that HSF1 (show HSF1 ELISA Kits) overexpression protects against TDP-43 pathology by upregulation of chaperones, especially HSP70 (show HSP70 ELISA Kits), rather than enhancing autophagy
superoxide dismutase (show SOD1 ELISA Kits) function of SOD1 (show SOD1 ELISA Kits) might not be required to preserve DNA integrity in motor neurons, at least when the function of TDP-43 is unaltered
The findings of this study support a role for nuclear depletion of TDP-43 in the pathogenesis of AD and provide strong rationale for developing novel therapeutics to alleviate the depletion of TDP-43 and functional antemortem biomarkers associated with its nuclear loss.
These results suggested that nuclear localization signal -tagged TDP25 (a carboxyl-terminal fragment of TDP-43) can change its structure to use ordered oligomeric but nontoxic state. Moreover, the structure of ordered oligomers as well as nuclear sequestration may be important in mediating cytotoxicity in ALS pathology.
Mutatgion M337V in TDP-43 impaired the Nrf2 (show NFE2L2 ELISA Kits)/ARE pathway by reducing the expression of MafK and JDP2 (show JDP2 ELISA Kits) proteins.
The suppression of TDP-43 mitochondrial localization abolishes WT and mutant TDP-43-induced mitochondrial dysfunction and neuronal loss, and improves phenotypes of transgenic mutant TDP-43 mice.
Data indicate a method for site-directed single nucleotide editing in two disease-related genes, DNA binding protein (show CNBP ELISA Kits) tardbp and RNA binding protein fus (show FUS ELISA Kits).
Loss of ALS-associated TDP-43 in zebrafish causes muscle degeneration, vascular dysfunction, and reduced motor neuron axon outgrowth.
TARDBP and FUS (show FUS ELISA Kits) act in a pathogenic pathway that is independent of SOD1 (show SOD1 ELISA Kits).
HIV-1, the causative agent of acquired immunodeficiency syndrome (AIDS), contains an RNA genome that produces a chromosomally integrated DNA during the replicative cycle. Activation of HIV-1 gene expression by the transactivator Tat is dependent on an RNA regulatory element (TAR) located downstream of the transcription initiation site. The protein encoded by this gene is a transcriptional repressor that binds to chromosomally integrated TAR DNA and represses HIV-1 transcription. In addition, this protein regulates alternate splicing of the CFTR gene. A similar pseudogene is present on chromosome 20.
