| description | Abstract The Egyptian spiny mouse, Acomys cahirinus, is a recently described model organism for regeneration studies. It has surprising powers of regeneration with relatively fast repairing mechanisms and reduced inflammation form compared to other mammals. Although several studies have documented the exceptional capabilities of Acomys to regenerate different tissues after injury, its response to different cellular and genetic stresses is not yet investigated. Therefore, the current study aimed to investigate Acomys abilities to resist genotoxicity, oxidative stress and inflammation induced by acute and subacute treatments with lead acetate. Responses of Acomys were compared with those of the lab mouse (Mus musculus), which displays signatures of the “typical” mammalian response to various stressors. Cellular and genetic stresses were induced by using acute and subacute doses of Lead acetate (400 mg/kg and 50 mg/kg for 5 days, respectively). The assessment of genotoxicity was carried out by using comet assay, while oxidative stress was evaluated by measuring the biomarkers; MDA, GSH and antioxidant enzymes CAT and SOD. Moreover, inflammation was assessed by analyzing the expression of some inflammatory-regeneration-related genes: CXCL1, IL1-β, and Notch 2 and immunohistochemical staining of TNF-α protein in brain tissue, in addition to histopathological examination of brain, liver, and kidneys. The obtained results revealed a unique resistance potency of Acomys to genotoxicity, oxidative stress, and inflammation in certain tissues in comparison to Mus. Altogether, the results revealed an adaptive and protective response to cellular and genetic stresses in Acomys. |
