Retinoic acid (RA) can induce growth arrest and neuronal differentiation of neuroblastoma cells and has been used in clinic for treatment of neuroblastoma. It has been reported that RA induces the expression of several HOXD genes in human neuroblastoma cell lines, but their roles in RA action are largely unknown. The HOXD cluster contains nine genes (HOXD1,(More)
And-Invert Cones (AICs) have been suggested as an alternative to the ubiquitous Look-Up Tables (LUTs) used in commercial FPGAs. The original article suggesting the new architecture made some untested assumptions on the circuitry needed to implement AIC architectures and did not develop completely the toolset necessary to assess comprehensively the idea. In(More)
BACKGROUND The nuclear protein high-mobility group box 1 (HMGB1) is a key trigger for the inflammatory reaction during liver ischemia reperfusion injury (IRI). Hydrogen treatment was recently associated with down-regulation of the expression of HMGB1 and pro-inflammatory cytokines during sepsis and myocardial IRI, but it is not known whether hydrogen has an(More)
BACKGROUND Reactive oxygen and nitrogen species are key molecules that mediate neuropathic pain. Although hydrogen is an established antioxidant, its effect on chronic pain has not been characterized. This study was to investigate the efficacy and mechanisms of hydrogen-rich normal saline induced analgesia. METHODOLOGY/PRINCIPAL FINDINGS In a rat model of(More)
BACKGROUND The purpose of this study was to synthesize and evaluate hyperbranched cationic glycogen derivatives as an efficient nonviral gene-delivery vector. METHODS A series of hyperbranched cationic glycogen derivatives conjugated with 3-(dimethylamino)-1-propylamine (DMAPA-Glyp) and 1-(2-aminoethyl) piperazine (AEPZ-Glyp) residues were synthesized and(More)
Cellular differentiation is characterized by the acquisition of specialized structures and functions, cell cycle exit, and global attenuation of the DNA damage response. It is largely unknown how these diverse cellular events are coordinated at the molecular level during differentiation. We addressed this question in a model system of neuroblastoma cell(More)
BACKGROUND The purpose of this study was to investigate the downregulation of mRNA expression of vascular endothelial growth factor (VEGF) by triamcinolone acetonide acetate (TAA)-loaded chitosan nanoparticles in human retinal pigment epithelial cells. METHODS TAA-loaded deoxycholic acid-modified chitosan (TAA/DA-Chit) nanoparticles were prepared via a(More)
The Polycomb transcription repressor BMI1 is highly expressed in human neuroblastomas and is required for the clonogenic self-renewal and tumorigenicity of human neuroblastoma cell lines. The molecular basis of BMI1 action in neuroblastoma cells is not well understood. Here we report that BMI1 has a critical role in stabilizing cyclin E1 by repressing the(More)
The extracellular signal-regulated kinase (ERK) signaling pathway participates in various cell responses, such as proliferation, migration, differentiation and death. In neuronal apoptosis, the ERK pathway has been shown to have a dual role. Although the majority of studies have demonstrated the ERK pathway to have an anti-apoptotic role in neurons,(More)
A number of case reports now indicate that rocuronium can induce a number of serious side effects. We hypothesized that these side effects might be mediated by the inhibition of nicotinic acetylcholine receptors (nAChRs) at superior cervical ganglion (SCG) neurons. Conventional patch clamp recordings were used to study the effects of rocuronium on nAChR(More)
