Regulated necrosis (necroptosis) and apoptosis are crucially involved in severe cardiac pathological conditions, including myocardial infarction, ischemia-reperfusion injury and heart failure. Whereas apoptotic signaling is well defined, the mechanisms that underlie cardiomyocyte necroptosis remain elusive. Here we show that receptor-interacting protein 3(More)
A metabonomic approach using (1)H NMR spectroscopy was adopted to investigate the metabonomic pattern of rat urine after oral administration of environmental endocrine disruptors (EDs) polychlorinated biphenyls (PCBs) and 2,3,7,8-tetrachlorodibenzo- p-dioxin (TCDD) alone or in combination and to explore the possible hepatotoxic mechanisms of combined(More)
Peptides inhibiting angiotensin-I converting enzyme (ACE, EC. are possible cures of hypertension. Food-derived ACE-inhibitory peptides are particularly attractive because of reduced side effects. Previously, we reported ACE-inhibitory activity of grass carp protein hydrolysates. In this work, we report steps for purifying the ACE-inhibitory(More)
Butenolide, 4-acetamido-4-hydroxy-2-butenoic acid gamma-lactone is one of the mycotoxins produced by Fusarium species which are often found on cereal grains and animal feeds throughout the world. It has been implicated as the etiology of some diseases both in animals and in humans. Though butenolide represents a potential threat to animal and human heath,(More)
In this study, the delayed effect and related mechanism after chlorpyrifos (CPF) withdrawal was studied in primary rat hippocampal neurons. The results showed that 10 muM CPF induced no detectable cytotoxicity during 96 h continuous exposure while its withdrawal after 48 h exposure induced evident cytotoxicity, as indexed by decreased methyl thiazolyl(More)
Butenolide (CAS No. 16275-44-8), a mycotoxin produced by several Fusarium species, has been shown to be a potential risk factor for animal and human health. This study was undertaken to investigate the potential oxidative damage of butenolide to biomembranes in vitro using the erythrocyte membrane model. Following exposure of isolated rat erythrocyte(More)
Quinolones (QNs)-induced arthropathy is an important toxic effect in immature animals leading to restriction of their therapeutic use in pediatrics. However, the exact mechanism still remains unclear. Recently, we have demonstrated that ofloxacin, a typical QN, induces apoptosis of alginate microencapsulated juvenile rabbit joint chondrocytes by disturbing(More)
Reprogramming of somatic cells into inducible pluripotent stem cells (iPSCs) provides an alternative to using embryonic stem cells (ESCs). Mesenchymal stem cells derived from human hair follicles (hHF-MSCs) are easily accessible, reproducible by direct plucking of human hairs. Whether these hHF-MSCs can be reprogrammed has not been previously reported. Here(More)
Fusarium mycotoxin toxicosis has been implicated in the etiology of Keshan disease, an endemic mitochondrial cardiomyopathy prevailing in certain areas of China. Butenolide (4-acetamido-4-hydroxy-2-butenoic acid gamma-lactone) is one of the Fusarium mycotoxins which are frequently detected from cereal grains in endemic areas. A recent study indicates that(More)
Human hair follicle mesenchymal stem cells (hHF-MSCs) are capable of differentiating into smooth muscle cells (SMCs) in response to transforming growth factor-β (TGF-β), and thus can be used for cardiovascular tissue engineering and regenerative medicine. However, the precise molecular mechanisms underlying SMC conversion of hHF-MSCs are still undefined.(More)
