ALS-Related Mutant FUS Protein Is Mislocalized to Cytoplasm and Is Recruited into Stress Granules of Fibroblasts from Asymptomatic <b><i>FUS </i></b>P525L Mutation Carriers
<b><i>Background:</i></b> Amyotrophic lateral sclerosis (ALS) shows a strong genetic basis, with <i>SOD1</i>, <i>FUS</i>, <i>TARDBP</i>, and <i>C9ORF72 </i>being the genes most frequently involved<i>. </i>This has allowed identification of asymptomatic mutation carriers, which may be of help in understanding the molecular changes preceding disease onset. <b><i>Objectives:</i></b> We studied the cellular expression of FUS protein and the effect of heat-shock- and dithiothreitol-induced stress in fibroblasts from <i>FUS</i> P525L mutation carriers, healthy controls, and pati…
Hsp60 response in experimental and human temporal lobe epilepsy due to hyppocampal sclerosis
Hsp60 is widely distributed in the brain, and its alteration has been involved in different neurological disorders. Epilepsy is considered one of the most common neurological disorders and typically involves the hippocampal formation. Compelling evidence describes a role of mitochondria, oxidative stress and both innate and adaptive immunity during epileptogenesis in temporal lobe epilepsy due to hyppocampal sclerosis (TLE-HS). Here, we investigate the Hsp60 involvement in experimental and human epilepsy. Firstly, expression and distribution of Hsp60 in epileptic hippocampi of a rat model of temporal lobe epilepsy (TLE), based on the phenomenon of maximal dentate gyrus activation (MDA), usi…
Hsp60 response in experimental and human temporal lobe epilepsy
The mitochondrial chaperonin Hsp60 is a ubiquitous molecule with multiple roles, constitutively expressed and inducible by oxidative stress. In the brain, Hsp60 is widely distributed and has been implicated in neurological disorders, including epilepsy. A role for mitochondria and oxidative stress has been proposed in epileptogenesis of temporal lobe epilepsy (TLE). Here, we investigated the involvement of Hsp60 in TLE using animal and human samples. Hsp60 immunoreactivity in the hippocampus, measured by Western blotting and immunohistochemistry, was increased in a rat model of TLE. Hsp60 was also increased in the hippocampal dentate gyrus neurons somata and neuropil and hippocampus proper …
