Studies on the molecular clockwork during aging have been hitherto addressed to core clock genes. These previous investigations indicate that circadian profiles of core clock gene expression at an advanced age are relatively preserved in the master circadian pacemaker and the hypothalamic suprachiasmatic nucleus (SCN), and relatively impaired in peripheral(More)
Therapeutic strategies for the fatal neurodegenerative disease amyotrophic lateral sclerosis (ALS) are actually minimally effective on patients' survival and quality of life. Although stem cell therapy has raised great expectations, information on the involved molecular mechanisms is still limited. Here we assessed the efficacy of the systemic(More)
Biological rhythms are frequently disturbed with advancing age, and aging-related changes of glia in the hypothalamic suprachiasmatic nucleus (SCN), the master circadian pacemaker, require special attention. In particular, astrocytes contribute to SCN function, and aging is associated with increased inflammatory activity in the brain, in which microglia(More)
Body function rhythmicity has a key function for the regulation of internal timing and adaptation to the environment. A wealth of recent data has implicated endogenous biological rhythm generation and regulation in susceptibility to disease, longevity, cognitive performance. Concerning brain diseases, it has been established that many molecular pathways(More)
Lower motoneuron abnormalities have been extensively documented in the murine model of familial amyotrophic lateral sclerosis, whereas information on corticospinal neurons in these mice is very limited. We investigated 1) mRNA levels of inflammation-related molecules in the deep layers in which corticospinal neurons reside, 2) corticospinal neurons labeled(More)
