Mesenchymal stem cells (MSCs) have both multi-lineage differentiation potential and immunosuppressive properties, making them ideal candidates for regenerative medicine. However, their immunosuppressive properties potentially increase the risk of cancer progression and opportunistic infections. In this study, MSCs isolated from human umbilical cord blood(More)
Intrauterine asphyxia is one of the major contributors for perinatal death, mental and physical disorders of surviving children. Brain-derived neurotrophic factor (BDNF) provides a promising solution to hypoxic injury due to its survival-promoting effects. In an attempt to identify possible molecular mechanisms underlying the neuroprotective role of BDNF,(More)
Multidrug resistance (MDR) is a significant problem underlying the poor prognosis associated with gliomas. Hypoxia-inducible factor-1alpha (HIF-1alpha) is thought to induce the genes expression involved in MDR. To evaluate the effect of silencing HIF-1alpha in human glioma T98G cells, cells were transfected with HIF-1alpha-small interference RNA(More)
Antibodies against CD25 would be novel tools for the diagnosis and treatment of adult T cell leukemia lymphoma (ATLL) and many other immune disorders. In our previous work, we successfully produced the single-chain fragment of a variable antibody against CD25, the Dmab(scFv) antibody, using Pichia pastoris. Here, we describe a novel form of an antibody(More)
Hypoxia-inducible factor-1 alpha (HIF-1α) is one of the key regulators of hypoxia/ischemia. MicroRNA-494 (miR-494) had cardioprotective effects against ischemia/reperfusion (I/R)-induced injury, but its functional relationship with HIF-1α was unknown. This study was undertaken to determine if miR-494 was involved in the induction of HIF-1α. Quantitative(More)
BACKGROUND Recent evidence shows that allograft survival rates show a positive correlation with the number of circulating T regulatory cells (Tregs). This study investigated both the number and the cytokine profiles exhibited by Foxp3+ Tregs in blood, spleen and lymph nodes of Lewis rat recipients of BN rat cardiac allografts after a single-dose of(More)
Tumor-homing peptides that recognize specific markers on tumor cells have shown potential as drug carriers for targeted cancer therapy. Bombesin receptors are frequently overexpressed or ectopically expressed in a wide range of human tumors. Bombesin and its analogues have been widely used as drug carriers for tumor imaging and tumor therapy. However, the(More)
AIMS Although extracellular-regulated kinases (ERK) are a well-known central mediator in cardiac hypertrophy, no clinically available ERK antagonist has been tested for preventing cardiac hypertrophy. Selumetinib is a novel oral MEK inhibitor that is currently under Phase II and Phase III clinical investigation for advanced solid tumors. In this study, we(More)
Objective. To dissect the efficacy of Tol-DC therapy with or without IS in multiple animal models of transplantation. Methods and Results. PubMed, Medline, Embase, and the Cochrane Library were searched for reviews published up to April 2015. Six systematic reviews and a total of 61 articles were finally included. Data were grouped by organ transplantation(More)
