The response and susceptibility to astroglial degenerations are relevant to the distinctive properties of astrocytes in a hemodynamic-independent manner following status epilepticus (SE). Since impaired mitochondrial fission plays an important role in mitosis, apoptosis and programmed necrosis, we investigated whether the unique pattern of mitochondrial dynamics is involved in the characteristi...
abstract cancer is the leading cause of death worldwide. current anticancer drugs involve various toxic side effects; efforts are ongoing to develop new anticancer agents especially from the screening of natural compounds. present study investigated cytotoxic effects and mode of cell death induced by the caspian cobra venom in some human cancer cell lines. cytotoxic effects of snake venom toxin...
Cyanidin-3-glucoside (C3G) is the most common anthocyanin in dark grains and berries a food functional factor to improve visual health. However, mechanisms of C3G on blue light-induced retinal pigment epithelial (RPE) cell photooxidative damage needs further exploration. We investigated effects light-irradiated A2E-containing RPE cells explored whether sphingolipid, mitogen-activated protein ki...
Effects of the histone deacetylase (HDAC) inhibitor MS-275 have been examined in human leukemia and lymphoma cells (U937, HL-60, K562, and Jurkat) as well as in primary acute myelogenous leukemia blasts in relation to differentiation and apoptosis. MS-275 displayed dose-dependent effects in each of the cell lines. When administered at a low concentration (e.g., 1 M), MS-275 exhibited potent ant...
Apoptosis was induced rapidly in HeLa cells after exposure to bacterial Shiga toxin (Stx1 and Stx2; 10 ng/ml). Approximately 60% of HeLa cells became apoptotic within 4 h as detected by DNA fragmentation, terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling (TUNEL) assay, and electron microscopy. Stx1-induced apoptosis required enzymatic activity of the Stx1A subunit, and...
The Doberman pinscher (DP) canine breed displays a high incidence of idiopathic, nonischemic dilated cardiomyopathy (DCM) with increased mortality. A common mutation in DPs is a splice site deletion in the pyruvate dehydrogenase kinase 4 (PDK4) gene that shows a positive correlation with DCM development. PDK4, a vital mitochondrial protein, controls the switch between glycolysis and oxidative p...
Peroxisome proliferator–activated receptor alpha (PPARa) is a member of the nuclear factor PPAR family that regulates a variety of cellular functions, including lipid metabolism, cellular oxidative stress defense, and inflammatory responses. Based on the report that Wy14,643, a PPARa agonist, can upregulate uncoupling protein-2 (UCP-2), this study was conducted in primary cortical cells to dete...

Neuronal apoptosis is a key aspect of many different neurologic diseases, but the mechanisms remain unresolved. Recent studies have suggested a mechanism of innate immune-induced neuronal apoptosis through the stimulation of endosomal TLRs in neurons. TLRs are stimulated both by pathogen-associated molecular patterns as well as by damage-associated molecular patterns, including microRNAs releas...
