Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF superfamily, and has been identified as a novel mediator of fatty liver disease (FLD). The aim of our study was to further investigate the relationship between TRAIL and FLD. We found that soluble TRAIL (sTRAIL) concentrations in non-alcoholic FLD (NAFLD) patients(More)
We have examined the effects of the macrocyclic lactone protein kinase C (PKC) activator bryostatin 1 on taxol-induced apoptosis and inhibition of clonogenicity in the human monocytic leukemia cell line U937. Exposure of cells to bryostatin 1 (10 nM; 15 hr) after (but not before) a 6-hr incubation with 0.5 microM taxol significantly increased apoptosis and(More)
The signaling mechanism by which JNK affects mitochondria is critical to initiate apoptosis. Here we show that the absence of JNK provides a partial resistance to the toxic effect of the heavy metal cadmium. Both wild type and jnk-/- fibroblasts undergoing death exhibit cytosolic cytochrome c but, unlike wild type cells, the JNK-deficient fibroblasts do not(More)
Alkaloid berberine is widely used for the treatment of diarrhea and other diseases. Many laboratory studies showed that it exhibits anti-proliferative activity against a wide spectrum of cancer cells in culture. In this report we studied the mechanisms underlying the inhibitory effects of berberine on human osteosarcoma cells and on normal osteoblasts. The(More)
Bone degradation is a serious complication of chronic inflammatory diseases such as septic arthritis, osteomyelitis, and infected orthopedic implant failure. Up to date, effective therapeutic treatments for bacteria-caused bone destruction are limited. In our previous study, we found that LPS promoted osteoclast differentiation and activity through(More)
The c-Jun N-terminal kinase (JNK) mitogen-activated protein kinase (MAPK) signaling pathway mediates stress responses in cells. JNK activity is regulated by a protein kinase cascade consisting of a MAPK kinase (MKK) and a MAPK kinase kinase (MAPKKK). beta-Arrestin-2 acts as a scaffold by directly binding to the JNK3 isoform and also by recruiting MKK4 and(More)
Both the dystrophin-glycoprotein complex and alpha7beta1 integrin have critical roles in the maintenance of muscle integrity via the provision of mechanical links between muscle fibres and the basement membrane. Absence of either dystrophin or alpha7 integrin results in a muscular dystrophy. To clarify the role of alpha7 integrin and dystrophin in muscle(More)
Hereditary predisposition to develop neuroblastoma (Online Mendelian Inheritance in Man 256700), a pediatric cancer of the sympathetic nervous system, segregates as an autosomal dominant Mendelian trait. We performed linkage analysis on seven families with two or more first-degree relatives affected with neuroblastoma to localize a hereditary neuroblastoma(More)
Because of their feasibility and effectiveness, artificial intelligence-based intrusion detection systems attract considerable interest from researchers. However, when confronted with large-scale data sets, many artificial intelligence-based intrusion detection systems could suffer from a high computational burden, even though the feature selection method(More)
AIM To study the action of tanshinone II-A sulfonate (Tan) on adhesion molecule expression by cultured endothelial cells and platelets. METHODS Tumor necrosis factor alpha (TNF-alpha)-induced ICAM-1 expression on the cell surface and endothelial adhesivity toward HL-60 cells were studied using human umbilical vein endothelial cells (HUVEC).(More)
