    Abstract Objectives: Neuropathic pain is characterized by long-lasting, intractable pain. Sciatic nerve ligation is often used as an animal model of neuropathic pain, and the spared nerve injury (SNI) model, in which the common peroneal nerve (CPN) and tibial nerve (TN) are ligated, is widely used. In the present study, we evaluated the analgesic effect of a cholinergic agonist, carbachol, on a neuropathic pain model prepared by sural nerve (SN) ligation in mice.
    Methods: The SN was tightly ligated as a branch of the sciatic nerve. Mechanical and thermal allodynia, and hyperalgesia were assessed using von Frey filaments and heat from a hot plate. The analgesic effects of intracerebroventricularly-administered morphine and carbachol were compared.
    Results: SN ligation resulted in a significant decrease in pain threshold for mechanical stimulation 1 day after ligation. In response to thermal stimulation, allodynia was observed at 50°C and hyperalgesia at 53 and 56°C 3 days after ligation. Content of thiobarbituric acid reactive substances (TBARS) in the spinal cord increased significantly at 6 and 12 h after ligation. Acetylcholine content of the spinal cord also increased at 5 and 7 days after ligation. Intracerebroventricular administration of carbachol at 7 days after ligation produced a marked analgesic effect against mechanical and thermal stimuli, which was stronger and longer-lasting than morphine at all experimental time points.
    Conclusion: These findings suggest that cholinergic nerves are involved in allodynia and hyperalgesia of the SN ligation neuropathic pain model.

    Abstract A hybridoma clone 1F7 producing a monoclonal antibody against OTF9-63 mouse embryonal carcinoma cell line was isolated with the aid of the intrasplenic primary immunization technique. This antibody was capable of recognizing embryonal carcinoma cell lines originated from certain mouse strains, including 129/Sv, but not those which were established from other strains as well as human and other murine cell lines except FM3A, a mouse mammary carcinoma cell line. Indirect immunofluorescence study revealed that 1F7 antigen was expressed on early mouse embryos in a stage specific manner. In order to characterize the 1F7 antigenic molecules, we analyzed both glycoshingolipids and glycoproteins recovered from OTF9-63 by means of immunostaining after thin layer chromatography and SDS-polyacrylamide gel electrophoresis followed by Western blotting, respectively. It was concluded that 1F7 antigenic determinants were carried by 180 kDa polypeptides. One of the most interesting characteristics of 1F7 antigen is complete failure to express on the embryonic ectoderm of 5.5d and 6.5d embryos, one of cell types most closely related to embryonal carcinoma cells. 1F7 antibody may help analyse the process of teratocarcinogenesis in 129/Sv mice.

    Abstract 1,2,3,4-tetrahydroisoquinoline (TIQ) is endogenously present in the human brain, and some of its derivatives are thought to contribute to the induction of Parkinson's disease (PD)-like signs in rodents and primates. In contrast, the endogenous TIQ derivative 1-methyl-TIQ (1-MeTIQ) is reported to be neuroprotective.

    Abstract Painful peripheral neuropathy is a common adverse effect of paclitaxel (PTX) treatment. To analyze the contribution of transient receptor potential vanilloid 1 (TRPV1) in the development of PTX-induced mechanical allodynia/hyperalgesia and thermal hyperalgesia, TRPV1 expression in the rat spinal cord was analyzed after intraperitoneal administration of 2 and 4 mg/kg PTX. PTX treatment increased the expression of TRPV1 protein in the spinal cord. Immunohistochemistry showed that PTX (4 mg/kg) treatment increased TRPV1 protein expression in the superficial layers of the spinal dorsal horn 14 days after treatment. Behavioral assessment using the paw withdrawal response showed that PTX-induced mechanical allodynia/hyperalgesia and thermal hyperalgesia after 14 days was significantly inhibited by oral or intrathecal administration of the TRPV1 antagonist AMG9810. We found that intrathecal administration of small interfering RNA (siRNA) to knock down TRPV1 protein expression in the spinal cord significantly decreased PTX-induced mechanical allodynia/hyperalgesia and thermal hyperalgesia. Together, these results demonstrate that TRPV1 receptor expression in spinal cord contributes, at least in part, to the development of PTX-induced painful peripheral neuropathy. TRPV1 receptor antagonists may be useful in the prevention and treatment of PTX-induced peripheral neuropathic pain.

    Abstract Chemotherapy-induced peripheral neuropathy has an important impact on the quality of life of cancer patients. Vincristine-induced neuropathy is a major dose-limiting side effect. Symptoms of peripheral neuropathy are spontaneous pain, allodynia, and hyperalgesia. To analyze the contribution of substance P to the development of vincristine-induced mechanical allodynia/hyperalgesia, substance P levels in the rat spinal dorsal horn were analyzed after vincristine treatment. Mechanical allodynia/hyperalgesia was tested with the von Frey filaments 14 days after intraperitoneal (i.p.) administration of vincristine 0.1 mg/kg/day in rats. Vincristine-induced mechanical allodynia/hyperalgesia after day 14 was significantly inhibited by the neurokinin 1 receptor antagonist, aprepitant (20 mg/kg, s.c.). Immunohistochemistry showed that vincristine treatment significantly increased substance P expression (30.3% ± 2.4%) compared to saline treatment in the superficial layers of the spinal dorsal horn. Moreover, vincristine treatment significantly increased the substance P level in the spinal cord. These results suggest that vincristine treatment increases substance P in the spinal dorsal horn, and that aprepitant attenuates mechanical allodynia/hyperalgesia in vincristine-induced neuropathic rats.

    Abstract Industrial glucose feedstock prepared by enzymatic digestion of starch typically contains significant amounts of disaccharides such as maltose and isomaltose and trisaccharides such as maltotriose and panose. Maltose and maltosaccharides can be utilized in Escherichia coli fermentation using industrial glucose feedstock because there is an intrinsic assimilation pathway for these sugars. However, saccharides that contain α-1,6 bonds, such as isomaltose and panose, are still present after fermentation because there is no metabolic pathway for these sugars. To facilitate more efficient utilization of glucose feedstock, we introduced glvA, which encodes phospho-α-glucosidase, and glvC, which encodes a subunit of the phosphoenolpyruvate-dependent maltose phosphotransferase system (PTS) of Bacillus subtilis, into E. coli. The heterologous expression of glvA and glvC conferred upon the recombinant the ability to assimilate isomaltose and panose. The recombinant E. coli assimilated not only other disaccharides but also trisaccharides, including alcohol forms of these saccharides, such as isomaltitol. To the best of our knowledge, this is the first report to show the involvement of the microbial PTS in the assimilation of trisaccharides. Furthermore, we demonstrated that an L-lysine-producing E. coli harboring glvA and glvC converted isomaltose and panose to L-lysine efficiently. These findings are expected to be beneficial for industrial fermentation.
