It has been recognized that bone marrow stromal cell (BMSC) transplantation has beneficial effects on spinal cord injury in animal models and therapeutic trials. It is hypothesized that BMSCs provide microenvironments suitable for axonal regeneration and secrete some trophic factors to rescue affected cells from degeneration. However, the molecular and(More)
In this study we investigated the antioxidative effects of Oligonol (Amino Up Chemical Co., Ltd., Sapporo, Japan), a new polyphenol, in adipocytes. The levels of reactive oxygen species (ROS) and the expression of adipokine genes decreased in HW mouse white adipocytes upon treatment with Oligonol as compared to control cells. The transcriptional activity of(More)
Bone marrow stromal cells (BMSCs) have been studied as effective transplants for the treatment of spinal cord injury (SCI). Our previous study showed that BMSCs infused into the cerebrospinal fluid (CSF) exhibited distinct effects on the recovery of acute SCI. The present study examined the effects of BMSCs in sub-acute SCI (2weeks post-injury) by(More)
To explain why quercetin, a mutagenic flavonoid distributed widely in edible plants, showed no carcinogenicity in experimental animals, overall metabolic fate of the drug was pursued using radiolabeled compound. [4-(14)C]Quercetin was administered orally or intraperitoneally to male ACI rats and its distribution, metabolism and excretion were studied by(More)
Angiogenesis is the first regulatory step of tumor progression. Herein, we report on some findings that show that beta1,6-N-acetylglucosaminyltransferase V (GnT-V) functions as an inducer of angiogenesis that has a novel and completely different function from the original function of glycosyltransferase. A secreted type of GnT-V protein itself promoted(More)
It has been demonstrated that the infusion of bone marrow stromal cells (BMSCs) through the cerebrospinal fluid (CSF) has beneficial effects on acute spinal cord injury (SCI) in rats. The present study examined whether BMSC infusion into the CSF is effective for subacute (1- and 2-week post-injury), and/or chronic (4-week post-injury) SCI in rats. The(More)
PURPOSE This study was conducted to assess the safety and feasibility of intrathecal transplantation of autologous bone marrow-derived mononuclear cells for the treatment of patients with spinal cord injury. METHODS Ten patients were included in the study. Approximately 120 ml of bone marrow aspirate was obtained from bilateral iliac bone of patients with(More)
PURPOSE The effect of the transplantation of choroid plexus epithelial cells (CPECs) on locomotor improvement and tissue repair including axonal extension in spinal cord lesions was examined in rats with spinal cord injury (SCI). METHODS CPECs were cultured from the choroid plexus of green fluorescent protein (GFP)-transgenic rats, and transplanted(More)
NTAK (neural- and thymus-derived activator for ErbB kinases), also known as neuregulin-2, is a member of the epidermal growth factor (EGF) family, which binds directly to ErbB3 and ErbB4 and transactivates ErbB2. Because ErbB signaling has been implicated in various angiogenic mechanisms, the effect of NTAK (which has at least nine isoforms due to(More)
The effect of exercise training on tumor necrosis factor-alpha (TNF-alpha) signaling was investigated in rat epididymal adipocytes. Incubation of isolated adipocytes with TNF-alpha (20 ng/ml) for 5 h enhanced the expression of the inhibitor apoptosis protein 2 (IAP2) gene without any enhancement of caspase-3 activity in both the sedentary control (C) and(More)
