Diabetic retinopathy (DR) is a leading cause of vision loss among working-age adults. Retinal endothelial cell apoptosis is an early event in DR, and oxidative stress is known to play an important role in this pathology. Recently, we found that high glucose induces apoptosis in retinal neural cells by a caspase-independent mechanism. Here, we investigated the mechanisms underlying retinal endot...
Tumour necrosis factor (TNF)-induced death of oligodendrocytes, the cell type targeted in multiple sclerosis, is mediated by TNF receptor p55 (TNFR-p55). The ligation of TNFR-p55 induces several signal transduction pathways; however, the precise mechanism involved in human oligodendrocyte (hOL) death is unknown. We defined that TNF-induced death of hOLs is non-caspase dependent, as evidenced by...
BACKGROUND/AIMS Phosphatidylinositol (PI) regulates a variety of cell processes. The present study investigated the antitumor action of 1,2-dioleoyl-sn-glycero-3-phospho-(1'-myo-inositol)(DOPI) and 1,2-dipalmitoyl-sn-glycero-3-phospho-(1'-myo-inositol)(DPPI) on human malignant pleural mesothelioma (MPM) cell lines such as NCI-H28, NCI-H2052, NCI-H2452, and MSTO-211H cells. METHODS MTT assay, ...
BACKGROUND AND AIMS AIF (apoptosis inducing factor) is a flavin and NADH containing protein located within mitochondria required for optimal function of the respiratory chain. AIF may function as an antioxidant within mitochondria, yet when released from mitochondria it activates caspase-independent cell death. The Harlequin (Hq) mouse has a markedly reduced content of AIF, providing an experim...
Proteasome inhibitors (PI), a novel class of anticancer drugs, are relatively well tolerated and have recently been introduced into the clinic for the treatment of multiple myeloma. The tumor selectivity and low toxicity of PIs are surprising, given the crucial role of the ubiquitin/proteasome system in a multitude of cellular processes. Here, we show that systemic administration of PIs specifi...
OBJECTIVE Dracorhodin perchlorate (DP) was a synthetic analogue of the antimicrobial anthocyanin red pigment dracorhodin. It was reported that DP could induce apoptosis in human prostate cancer, human gastric tumor cells and human melanoma, but the cytotoxic effect of DP on human breast cancer was not investigated. This study would investigate whether DP was a candidate chemical of anti-human b...
The poor prognosis of pancreatic cancer and poor sensitivity to current therapeutics, associated with resistance to apoptosis, urge the search for new drugs. We previously described the induction of caspase-independent mithochondrial death in leukemia cells by Bobel-24 (AM-24) and derivatives. Here, we explored whether these compounds induce a similar cytotoxicity in human pancreatic carcinoma ...
Cardiovascular diseases such as hypertension are associated with a generalized skeletal myopathy including a proapoptotic phenotype. Current evidence suggests that exercise may alter apoptosis-related signaling in skeletal muscle; however, the effect of exercise on skeletal muscle DNA fragmentation and apoptotic signaling is unclear in hypertensive animals. Male normotensive Wistar Kyoto (WKY; ...
Exposure of people and animals to environments highly polluted with nickel (Ni) can cause pathologic effects. Ni compounds can induce apoptosis, but the mechanism and the pathway of Ni compounds-induced apoptosis are unclear. We evaluated the alterations of apoptosis, mitochondrial membrane potential (MMP), phosphoinositide-3-kinase (PI3K)/serine-threonine kinase (Akt) pathway, and Bcl-2 family...
