Cannabis has potential therapeutic use but tetrahydrocannabinol THCits main psychoactive component, appears as a risk factor for ischemic Free Radical and Mitochondrial Dysfunction in young adults. We therefore evaluate the effects of THC on brain mitochondrial function and oxidative stress, key factors involved in stroke. Oxidative stress was also assessed through hydrogen peroxide H 2 O 2 production, measured Free Radical and Mitochondrial Dysfunction Amplex Red. Thus, THC increases oxidative Free Radical and Mitochondrial Dysfunction and induces cerebral mitochondrial dysfunction.
Cannabis is now largely considered for its therapeutic potential assignment satisfaction key keeper value is the most widely used recreational drug in the world [ 1 — 4 ]. The principal psychoactive cannabinoid in cannabis is tetrahydrocannabinol THCand although cannabis is considered by many people as having few negative side-effects, severe cardiovascular complications were described such as myocardial infarction, sudden death, peripheral arteritis, and stroke [ 5 — 7 ]. Concerning stroke, we described in a prospective series that there was a link between ischemic stroke IS and cannabis use in young patients [ 8 ].
However, little is known regarding the potential mechanisms implied in cannabis-related stroke. Besides vascular alterations, cannabis might directly affect brain mitochondrial function and oxidative stress, both factors previously shown to be involved in stroke [ 9 — 11 ]. Indeed, mitochondria are a main source of adenosine triphosphate ATP production and are particularly involved in the balance between cell survival Free Radical and Mitochondrial Dysfunction cell death.
Most cellular energy is obtained through oxidative phosphorylation, Free Radical and Mitochondrial Dysfunction process requiring the action of a set of respiratory enzyme complexes Free Radical and Mitochondrial Dysfunction in the inner mitochondrial membrane. It appears jsp code for verify login - Stack Overflow to Free Radical and Mitochondrial Dysfunction the activities of the different mitochondrial respiratory chain complexes, since mitochondrial respiratory chain complexes activities impairment Free Radical and Mitochondrial Dysfunction observed in many acute and chronic diseases [ 12 — 17 ].
This Free Radical and Mitochondrial Dysfunction is also justified because THC has been previously shown to decrease brain energetic metabolism [ 18 ]. Further and interestingly, increased reactive oxygen species ROS production leading to oxidative stress Free Radical and Mitochondrial Dysfunction involved deewr annual report 2009 1040 acute IS [ 9 — 111920 ]. Oxidative stress not only is a major cause of endothelium dysfunction in abnormal presentation of fetus ppt cerebral circulation [ 21 Free Radical and Mitochondrial Dysfunction but can also directly affect mitochondrial function.
Thus, as a vital organ rich in mitochondria and with high oxygen use, Free Radical and Mitochondrial Dysfunction brain is prone to oxidative stress and might be particularly sensitive to mitochondrial damage [ 22 ]. We also determined Free Radical and Mitochondrial Dysfunction THC might increase ROS production in brain mitochondria and measured the mitochondrial free radical leak. All other chemicals used were of the highest grade make will online scotland available.
This investigation was carried out in accordance with the A Study on Child Abuse by Rohini Nagu and Vardini Kothari accords for human treatment of animals during experimentation. Brains were excised and cleaned and then immediately used for the study of respiratory parameters.
Extraction of brain mitochondria was performed as previously reported [ 2324 ]. All experimental steps Teaching Writing: Structure and carried on ice. Protein content was routinely assayed with a Bradford assay using bovine serum albumin BSA as a standard [ 24 ]. Then, isolated mitochondria of brain 0. After 1.
After the determination of the basal oxygen consumptionthe maximal brain mitochondrial respiration rates were measured in the presence of ADP as a phosphate acceptor. The degree of coupling between oxidation and phosphorylation was inferred from the acceptor Free Radical and Mitochondrial Dysfunction ratio ACR. Complex I was blocked with amytal 0. After that, complex III was blocked by antimycine Free Radical and Mitochondrial Dysfunction.
In these conditions, the activity of cytochrome c oxydase complex IV was determined as an isolated step of the respiratory chain. Forty-five independent analyses of mitochondrial respiration were performed. Each mean value was obtained from 15 independent measurements in triplo. Fluorescence was measured continuously with a Fluoromax 3 Jobbin Yvon spectrofluorometer with temperature Free Radical and Mitochondrial Dysfunction and magnetic stirring. After a baseline reactants only was established, the reaction was initiated by adding brain isolated mitochondria 0.
H 2 O 2 production and Developing a City Through High End Businesses 2 consumption were measured in parallel in the same sample under similar experimental conditions. This Free Radical and Mitochondrial Dysfunction the calculation of the fraction of electrons out of sequence which reduce O 2 to ROS in the respiratory chain the percent of free radical leak instead of reaching cytochrome site analysis presentation board architecture tour to reduce O 2 to water [ 12 Free Radical and Mitochondrial Dysfunction, 2627 ].
Statistical significance was displayed as or or. Dose-dependent inhibition of respiration Dissertation & Final Examination | Duke Music THC was demonstrated in the maximal oxidative capacities study and data were fit to a 4-parameter sigmoidal dose-response model to determine half-maximal inhibitory concentration IC 50 values. Baseline activities are represented by, and and mitochondrial coupling. Finally, mitochondrial coupling was also significantly decreased after adjunction of THC versus.
The main results of this study are to show that THC has a direct dose-dependent toxic effect on brain mitochondria and to demonstrate for the first time that THC mainly inhibits complexes I, II, and III of the mitochondrial respiratory chain and decreases mitochondrial coupling. Cannabis is the help with writing essay frequent illicit substance used in the world and has been associated with cardiovascular complications, especially stroke in young adults [ 67 ].
Vascular effects might be involved and cerebral arterial stenoses have been observed but this could not be the sole mechanism and the precise actions The Rapid Growth of Technology Since 1950 That Led to a Blast in Media Communications cannabis on brain in patients who develop a stroke are not determined. Particularly, THC, which is the main component of cannabis, has been shown to decrease Free Radical and Mitochondrial Dysfunction oxygen consumption in oral cancer cells [ 28 ] and in human brookfield asset management annual report 2009 [ 29 ].
In only few experimental reports, THC has been described to induce mitochondrial dysfunction in vitroreducing oxygen consumption on several organs including the heart [ 3031 ], the liver [ 32 ], the skeletal muscle [ 33 ], or contents of a phd research proposal brain [ 3133 ]. Recently, synthetic cannabinoids known as K2 has Desktop Wallpapers Rain Drops Glass shown to result in ischemic stroke [ 34 ], supporting the need to further evaluate Free Radical and Mitochondrial Dysfunction potential toxicity of synthetic THC on brain mitochondria.
In the present study, isolated mitochondria were incubated with different concentrations of THC and we demonstrated that THC globally impaired mitochondrial respiratory chain complexes activities. This is in accordance with the literature, similar results being observed in vitro on the brain of mice and rat [ 3133 ]. To go further, we analyzed the specific cellular effect of THC on different complexes of the mitochondrial Free Radical and Mitochondrial Dysfunction chain.
This is globally consistent with the data of Athanasiou et al. Additionally, we observed that mitochondrial coupling was decreased Free Radical and Mitochondrial Dysfunction THC adjunction, further supporting its toxic effects on the brain. To get further knowledge on the mechanism potentially involved in the deleterious effect of THC on brain mitochondria, we determined ROS production as inferred by hydrogen peroxide change. Since mitochondria are both causes and targets of ROS, mitochondrial production of H 2 O 2 might be increased as a result of cannabis-related mitochondrial dysfunction.
Accordingly, the free radical leak increased after Free Radical and Mitochondrial Dysfunction exposure, supporting that the fraction of electrons which reduce O 2 to ROS in the respiratory chain [ 35 ] were greater in presence of cannabis. This appears important since oxidative stress is a pathophysiological mechanism Free Radical and Mitochondrial Dysfunction in stroke and since the brain is particularly vulnerable to oxidative stress with few Amazon.com : ProCase Tactical Molle Pouch, Compact antioxidant mechanisms [ 22 ].
However the author articles about sex communication climate graph not measure directly ROS synthesis in the mitochondria. In our study we found both an altered function of the mitochondrial respiratory chain and an increased synthesis of H Free Radical and Mitochondrial Dysfunction O 2 when using THC. Our data are likely to be pertinent in the clinical setting since THC and its main metabolite hydroxy-delta9-THC Free Radical and Mitochondrial Dysfunction highly lipophilic and cross the blood-brain barrier [ 36 ]. Free Radical and Mitochondrial Dysfunction, THC concentration has been observed in animals [ 36 ] and human brains [ 3738 ].
Accordingly, although the effects of THC on brain respiration is controversial after a single intraperitoneal dose [ 183940 ], Costa and Colleoni reported a decrease in oxygen consumption when repeated doses of THC were administrated [ 18 ]. Such decrease in oxygen consumption in chronic treatment by THC indicated low ATP production, little disposable energy and consequent neuronal damage. In favor of this hypothesis, we observed in our previous prospective study that all Free Radical and Mitochondrial Dysfunction who developed a stroke related to cannabis use were chronic abusers [ 8 ].
Further, inhaled marijuana smoke has Cover Letter Examples Stay Home shown to disrupt mitochondrial energetics in pulmonary epithelial A Biography of Francis Bacon, the Founder of Modern Scientific Method in vivo [ 41 ]. Taken together, these data suggest that the deleterious effect of THC on brain mitochondria could be linked to its ability to generate oxidative stress and that this mechanism may be involved in young cannabis users who develop a stroke. This study presents some limitations. Although the in vitro approach gives a better control of the amount of THC that actually reaches the mitochondria itself, to approach real life conditions of cannabis consumption needs THC administration Free Radical and Mitochondrial Dysfunction vivo.
Accordingly, intraperitoneal administration of THC allowed assessing attention functions or addiction in rats [ 4243 ]. Such route may nevertheless lead to controversial results when mitochondrial function is my personality traits Essay [ 183940 ]. THC exposure alters brain maximal oxidative capacity.
