In our previous study, we found that pretreatment with lipoamide (LM) more effectively than alpha-lipoic acid (LA) protected retinal pigment epithelial (RPE) cells from the acrolein-induced damage. However, the reasons and mechanisms for the greater effect of LM than LA are unclear. We hypothesize that LM, rather than the more direct antioxidant LA, may act more as an indirect antioxidant. In t...
Acetaminophen overdose is the leading cause of acute liver failure. One dose of 10-15 g causes severe liver damage in humans, whereas repeated exposure to acetaminophen in humans and animal models results in autoprotection. Insight of this process is limited to select proteins implicated in acetaminophen toxicity and cellular defence. Here we investigate hepatic adaptation to acetaminophen toxi...
Multidrug resistance protein 4 (MRP4; ABCC4) is an ATP binding cassette transporter that facilitates the excretion of bile salt conjugates and other conjugated steroids in hepatocytes and renal proximal tubule epithelium. MRP4/Mrp4 undergoes adaptive upregulation in response to oxidative and cholestatic liver injury in human and animal models of cholestasis. However, the molecular mechanism of ...
This paper aims to explore whether pretreatment with dexmedetomidine (Dex) has antioxidative and renal protective effects during orthotopic autologous liver transplantation (OALT) and its impact on nuclear factor erythroid 2-related factor 2 (Nrf2) activation. Sprague-Dawley rats were randomized into groups that include sham-operated (group S), model (group M), low dose Dex (group D1), high dos...
Organic-inorganic hybrid molecules can exhibit biological activities by controlling the activities of their individual components. These molecules can be applied as seed/lead compounds in drug development, and can be used as molecular probes in chemical biology for the elucidation of the molecular mechanisms of biological systems. In this review, we introduce copper diethyldithiocarbamate (Cu10...
Multiple myeloma (myeloma in short) is an incurable cancer of antibody-producing plasma cells that comprise 13% of all hematological malignancies. The proteasome inhibitor bortezomib has improved treatment significantly, but inherent and acquired resistance to the drug remains a problem. We here show that bortezomib-induced cytotoxicity was completely dampened when cells were supplemented with ...
This study aimed to evaluate the effects of vitamin E (VE), ferulic acid (FA) and their combination supplementation on meat quality and antioxidant capacities of finishing pigs. Sixty barrows were randomly allocated to four experimental diets using a 2×2 factorial arrangement with 2 VE supplemental levels (0 or 400 mg/kg) and 2 FA supplemental levels (0 or 100 mg/kg) in basal diets. After 28 da...
INTRODUCTION Environmental factors causing oxidative stress are known to be associated with asthma morbidity. The antioxidative gene NFE2L2 has been implicated in asthma development in mice models. In humans, the SNPs -617C/A and -653G/A, located at the promoter region of NFE2L2 gene, have been found associated with the susceptibility to develop diverse chronic-degenerative diseases. OBJECTIV...
Arsenic produces liver disease through the oxidative stress. While lutein can alleviate cytotoxic and oxidative injury, nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a critical role in defending oxidative species. However, the mechanisms by which lutein protects the liver against the effect of arsenic are not known. Therefore, this study aims to investigate the mechanisms inv...
The nuclear factor erythroid 2-related factor 2 (Nrf2)-mediated antioxidant signaling pathway is a key target for cancer chemoprevention. Recent studies have that Nrf2 activation may be the result of an increase in Nrf2 protein stability. Mangiferin (MA), a compound monomer extracted from the mango plant, has antioxidant and cytoprotective activities. Our previous study demonstrated that MA inc...
