Pharmacotherapeutic potential of artemetin against amiodarone instigated sub-chronic hepatotoxicity via modulating TLR4/HMGB1/RAGE and NF-κB signaling pathways: An in-vivo and in-silico approach
Amiodarone (AMI) has been widely used in cardiac patients to prevent the onset of life-threating cardiac arrhythmias. However, its excessive use induces various organ damages including the liver. Artemetin (ART) is a flavonoid that exhibits immense medicinal values. This investigation explored the palliative potential of ART against AMI induced sub-chronic hepato-toxicity. Thirty-two rats (Sprague Dawley) were randomly apportioned into control, AMI (40 mgkg−1), AMI (40 mgkg−1) + ART (1.5 mgkg−1) and ART (1.5 mg/kg) alone treated group. Our findings elucidated that AMI administration instigate severe hepatocellular inflammation which is evident by elevated gene expression of interleukin-6 (IL-6), receptor for advanced glycation end products (RAGE), tumor necrosis factor- α (TNF-α), cyclooxygenase-2 (COX-2), monocyte chemoattractant protein-1 (MCP-1), high mobility group box1 (HMGB1), interleukin-1β (IL-1β), nuclear factor-kappa B (NF-κB), toll-like receptor 4 (TLR4). AMI exposure promoted the levels of reactive oxygen species (ROS) and malondialdehyde (MDA) while suppressing the activities of superoxide dismutase (SOD), heme oxygenase-1 (HO-1), glutathione reductase (GSR), glutathione Peroxidase (GPx), catalase (CAT), and glutathione (GSH). Besides, AMI intoxication lowered the levels of albumin and total proteins while increasing the levels of ALT, GGT, AST, and ALP. Moreover, AMI administration exacerbated Caspase-9, Bax and Caspase-3 while diminishing Bcl-2 concentrations. The normal morphology of hepatic tissues was disrupted following the AMI exposure. Nonetheless, ART treatment significantly alleviated hepatic damage via regulating abovementioned biochemical as well as histological impairments. Our results demonstrated that ART can strongly interact with the active sites of these proteins and exhibit potential as hepatoprotective agent.
期刊介绍:
Toxicon has an open access mirror Toxicon: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. An introductory offer Toxicon: X - full waiver of the Open Access fee.
Toxicon''s "aims and scope" are to publish:
-articles containing the results of original research on problems related to toxins derived from animals, plants and microorganisms
-papers on novel findings related to the chemical, pharmacological, toxicological, and immunological properties of natural toxins
-molecular biological studies of toxins and other genes from poisonous and venomous organisms that advance understanding of the role or function of toxins
-clinical observations on poisoning and envenoming where a new therapeutic principle has been proposed or a decidedly superior clinical result has been obtained.
-material on the use of toxins as tools in studying biological processes and material on subjects related to venom and antivenom problems.
-articles on the translational application of toxins, for example as drugs and insecticides
-epidemiological studies on envenoming or poisoning, so long as they highlight a previously unrecognised medical problem or provide insight into the prevention or medical treatment of envenoming or poisoning. Retrospective surveys of hospital records, especially those lacking species identification, will not be considered for publication. Properly designed prospective community-based surveys are strongly encouraged.
-articles describing well-known activities of venoms, such as antibacterial, anticancer, and analgesic activities of arachnid venoms, without any attempt to define the mechanism of action or purify the active component, will not be considered for publication in Toxicon.
-review articles on problems related to toxinology.
To encourage the exchange of ideas, sections of the journal may be devoted to Short Communications, Letters to the Editor and activities of the affiliated societies.
