We investigated the role of prostacyclin (PGI(2)) in the development of compression trauma-induced spinal cord injury (SCI) in rats. When measured after induction of SCI, tissue levels of 6-keto-PGF(1), a stable PGI(2) metabolite, thromboxane B(2) (TXB(2)), a stable metabolite of thromboxane A(2), myeloperoxidase (MPO) activity, and tumor necrosis factor(More)
Activated protein C (APC), an important inhibitor of the coagulation system, has recently been shown to prevent tissue injury by blocking the activation of leukocytes. To determine whether APC can also prevent post-traumatic spinal cord injury (SCI), a condition in which leukocytes play an important role, we tested the effects of APC on SCI induced in rats(More)
The stimulation of sensory neurons in the gastrointestinal (GI) tract improves cognitive function by increasing the hippocampal production of insulin-like growth factor-I (IGF-I) in mice. In the current study, we examined whether oral administration of desalted deep-sea water (DSW) increases the hippocampal production of IGF-I by stimulating sensory neurons(More)
Calcitonin gene-related peptide (CGRP) released from sensory neurons increases the production of a neuroprotective substance insulin-like growth factor I (IGF-I), and sensory neuron stimulation contributes to a reduction of spinal cord injury (SCI) by inhibiting inflammatory responses in rats. Because receptors for prostaglandin E₂ (EP receptors) are(More)
Insulin-like growth factor-I (IGF-I) exerts beneficial effects on cognitive function. The selective acetylcholinesterase inhibitor donepezil increases serum IGF-I levels in elderly subjects. Because stimulation of sensory neurons induces IGF-I production by releasing calcitonin gene-related peptide (CGRP) in the mouse brain, we hypothesized that donepezil(More)
Insulin-like growth factor I (IGF-I) exerts beneficial effects on cognitive function by inducing angiogenesis and neurogenesis in the hippocampus. We demonstrated that stimulation of sensory neurons in the gastrointestinal tract increased IGF-I production in the hippocampus, and thereby improved cognitive function in mice. Since cAMP plays a critical role(More)
Although urinary trypsin inhibitor (UTI) has been shown to inhibit tumor necrosis factor (TNF)-alpha- production, the detailed mechanism(s) remains unclear. This study was undertaken to elucidate the molecular mechanism(s) underlying this inhibitory effect in monocytes in vitro and in rats given lipopolysaccharide (LPS). TNF-alpha production by monocytes(More)
Calcitonin gene-related peptide (CGRP) increases insulin-like growth factor-I (IGF-I) production in fetal rat osteoblasts in vitro, suggesting that stimulation of sensory neurons might increase IGF-I production, thereby preventing apoptosis. We examined whether stimulation of sensory neurons by capsaicin might reduce reperfusion-induced hepatic apoptosis by(More)
We previously demonstrated that activation of sensory neurons increases endothelial prostaglandin I(2) (PGI(2)) production by releasing calcitonin gene-related peptide (CGRP). Since PGI(2) reduces post-traumatic spinal cord injury (SCI) by inhibiting tumor necrosis factor (TNF) production, activation of sensory neurons in the spinal cord tissue may(More)
Annotation and database system of full-length cDNA sequences was developed. As the components of the system, ORF annotation system, functional annotation system based on database search results, mapping annotation system, and integrated retrieval and display system were developed. In the ORF annotation system integrated analyses using conventional tools are(More)
