An energetic view of stress: Focus on mitochondria
Energy is required to sustain life and enable stress adaptation. At the cellular level, energy is largely derived from mitochondria - unique multifunctional organelles with their own genome. Four main elements connect mitochondria to stress: (1) Energy is required at the molecular, (epi)genetic, cellular, organellar, and systemic levels to sustain components of stress responses; (2) Glucocortic...
متن کاملNSAIDs, Mitochondria and Calcium Signaling: Special Focus on Aspirin/Salicylates
Aspirin (acetylsalicylic acid) is a well-known nonsteroidal anti-inflammatory drug (NSAID) that has long been used as an anti-pyretic and analgesic drug. Recently, much attention has been paid to the chemopreventive and apoptosis-inducing effects of NSAIDs in cancer cells. These effects have been thought to be primarily attributed to the inhibition of cyclooxygenase activity and prostaglandin s...
متن کاملToxicity of atorvastatin on isolated brain mitochondria
Background: Although the bio kinetics, metabolism and chemical toxicity of Atorvastatin are well known, until recently little attention was paid to the potential neurotoxic effect of Atorvastatin (Atv). Regarding the concrete evidences indicating Atv may reduce Coenzyme Q10 (CoQ10) levels through blockage of metalonate cycle, the present work aims to determine if Atorvastatin may provide toxic...
متن کاملGlucose-Modulated Mitochondria Adaptation in Tumor Cells: A Focus on ATP Synthase and Inhibitor Factor 1
Warburg's hypothesis has been challenged by a number of studies showing that oxidative phosphorylation is repressed in some tumors, rather than being inactive per se. Thus, treatments able to shift energy metabolism by activating mitochondrial pathways have been suggested as an intriguing basis for the optimization of antitumor strategies. In this study, HepG2 hepatocarcinoma cells were cultiva...
متن کاملResurrecting hope for antioxidant treatment of cardiovascular disease: focus on mitochondria.
Oxidative stress has been associated with cardiovascular disease and the development of hypertension in both humans and in animal models. Antioxidant therapy has been successful in ameliorating disease in animals, but the results from human studies have been largely disappointing. Despite these negative results, a wealth of evidence suggests that oxidative stress is involved in the development ...
