The mammalian Nrf/CNC proteins (Nrf1, Nrf2, Nrf3, p45 NF-E2) perform a wide range of cellular protective and maintenance functions. The most thoroughly described of these proteins, Nrf2, is best known as a regulator of antioxidant and xenobiotic defense, but more recently has been implicated in additional functions that include proteostasis and metabolic regulation. In the nematode Caenorhabdit...

Abstract Contact hypersensitivity (CHS) is an experimental model of human allergic contact dermatitis, one the representative skin diseases, where NLRP3 inflammasome plays a crucial role. Although regulation activity by cannabinoid 1 receptor (CB1R) has been shown in metabolic diseases such as obesity and type 2 diabetes, role CB1R CHS unclear. Here, we investigate putative using selective anta...

A number of age-related diseases have a low incidence in females, which is attributed to a protective effect of sex hormones. For instance, the female sex hormone estrogen (E2) has a well established cytoprotective effect against oxidative stress, which strongly contributes to ageing. However, the mechanism by which E2 exerts its protective activity remains elusive. In this study we address the...

OBJECTIVES In this study, we investigated the potential harmful effect of the exposure to silicon dioxide (SiO(2)) nanoparticles through in vitro toxicity assay using human bronchial epithelial cell, Beas-2B with a focus on the involvement of oxidative stress as the toxic mechanism. METHODS SiO(2)-induced oxidative stress was assessed by examining formation of reactive oxygen species (ROS), t...

We studied the implication of focal adhesion kinase (FAK) in cardiac mitochondrial biogenesis induced by mechanical stress. Prolonged stretching (2-12 h) of neonatal rat ventricular myocytes (NRVM) upregulated the main components of mitochondrial transcription cascade [peroxisome proliferator-activated receptor coactivator-1 (PGC-1α), nuclear respiratory factor (NRF-1), and mitochondrial transc...

Alpha Hope is a dietary supplement containing pyrroloquinoline quinone and elemental magnesium, which produces molecular hydrogen (H2 gas) when dissolved in water. We determined the impact of on Nrf-2, peroxisome proliferator-activated receptor-gamma coactivator (PGC-1α), citrate synthase (CS) activity C2C12 myoblasts. was titrated to three concentrations (PQQ) (10 nM, 100 1000 nM) treated for ...

A simple, rapid and sensitive spectrophotometric procedure has been proposed for the assay of fluoroquinolones viz., ciprofloxacin (CPF) and norfloxacin (NRF), and antiallergic drugs viz., methdilazine hydrochloride (MDH) and isothipendyl hydrochloride (IPH) in bulk and pharmaceutical formulations. The method is based on the reaction of selected drugs with Brilliant Blue G (BBG) in NaOAc-AcOH b...

BACKGROUND During programmed cell death, apoptotic cells are rapidly removed by phagocytes. How dying cells are recognized remains poorly understood. RESULTS Here we identify a secreted lipid transfer/LPS-binding family protein, NRF-5, which is required for efficient clearance of cell corpses. We observed that phosphatidylserine (PS), which is externalized to the outer leaflet of plasma membr...

BACKGROUND Lanthanum carbonate (FOSRENOL(®), Shire Pharmaceuticals) is an effective non-calcium, non-resin phosphate binder for the treatment of hyperphosphataemia in patients with chronic kidney disease (CKD). In this study, we used a rat model of chronic renal failure (CRF) to examine the long-term effects of controlling serum phosphorus with lanthanum carbonate treatment on the biochemical a...
