26792723 Collectively, these studies define Sig1R as a key mediator of TRAIL induction of cancer-specific killing.
26078401 Homozygous c.151+1G>T mutation in SIGMAR1 caused a novel form of autosomal recessive distal hereditary motor neuropathy (dHMN) in a Chinese consanguineous family; endoplasmic reticulum stress may have a role in the pathogenesis of dHMN
25902777 Central and peripheral pharmacological blockade of Sig-1R could be an effective option to treat inflammatory pain--{REVIEW}
25704016 Expression of mutant Sig-1R protein reduces mitochondrial ATP production, inhibits proteasome activity and causes mitochondrial injury, aggravating ER stress-induced neuronal death.
25704015 mutations of the SIGMAR1 gene worsen outcome in Alzheimer's disease and myotrophic lateral sclerosis supporting a role of Sig-1R in neurodegenerative disease.
25704014 overview of the biological mechanisms frequently associated with neurodegeneration, and discuss how sigma-1 receptors may alter these mechanisms to preserve or restore neuronal function.
25704013 Removal of the S1R gene in the Superoxide Dismutase-1 (SOD-1) mouse model of ALS exacerbated the neurodegenerative condition and resulted in a significantly reduced longevity.
25704011 Recent studies indicate that sigma-1 receptors, partly in sake of its unique subcellular localization, regulate the mitochondria function that involves bioenergetics and free radical generation.
