Septins are evolutionarily conserved cytoskeletal GTPases that can form heteropolymer complexes involved in cytokinesis and other cellular processes. We detected expression of the human septin genes Nedd5, H5, Diff6, and hCDC100 in postmortem brain tissues using the reverse transcription-coupled polymerase chain reaction and their products by immunoblot(More)
Gene mutations of Cu/Zn superoxide dismutase (SOD) have been discovered in familial amyotrophic lateral sclerosis (ALS). Oxidative stress also plays a role in the pathogenesis of sporadic ALS. Whether antioxidant therapy is beneficial in this fatal disease is now crucial. We have shown that SOD treatment improves neuromuscular dysfunction and morphological(More)
Among 222 primary colorectal cancers we examined, 58 showed no detectable APC mutations by the protein truncation test. We screened those 58 tumors for somatic mutations in the beta-catenin gene. Although amino acid substitutions in serine or threonine residues in exon 3 had been reported, we found no such mutations; however, in seven tumors, we detected(More)
We have carried out a comparative immunohistochemical study on four members of the septin family, CDCrel-1, Septin6, CDC10, and H5, which are abundantly expressed in the adult mouse brain. We found that each septin showed overlapping but distinct distribution at the levels of light and electron microscopy. CDCrel-1 was abundant in inhibitory presynaptic(More)
We studied trophic effects of angiotensin II, vasopressin, cholecystokinin, and oxytocin on explanted ventral spinal cord cultures from 13- and 14-day-old rat embryos. There was a significant neurite promoting effect of the spinal cord cultures by using angiotensin II, vasopressin, and cholecystokinin. Cholecystokinin had the most potent effect at any(More)
We studied trophic effects of angiotensin II, vasopressin and oxytocin on explanted ventral spinal cord cultures from 13-14-old day rat embryos. There was a significant neurite promoting effect in angiotensin II and vasopressin-treated cultures. Angiotensin II had the most potent effect at any concentrations. It became clear that minimum effective(More)
We measured fasting plasma amino acids in 20 patients with Parkinson's disease (PD) and 20 controls matched for age and sex. PD patients had significant elevations in plasma levels of aspartate, glutamate and glycine. The levels of other amino acids were not significantly different from those found in controls. No correlation was noted between PD severity(More)
R(-)-1-(benzo[b]thiophen-5-yl)-2-[2-(N,N-diethylamino) ethoxy]ethanol hydrochloride (T-588) enhances acetylcholine release from the frontal cortex and hippocampus in rats, and can ameliorate cognitive dysfunction in various amnesia models of rodents. T-588 protects rat cerebellar granule cells from glutamate neurotoxicity in culture. This agent also(More)
