Significance of the Wnt canonical pathway in radiotoxicity via oxidative stress of electron beam radiation and its molecular control in mice

Abstract

Radiation triggers the cell death events through signaling proteins, but the combined mechanism of events is unexplored. We intend to investigate how the combined cascade works throughout the radiation process and its significance over radiotoxicity. Thirty adult mice were irradiated with electron beam radiation, and five were served as a control (Non treated). Mice were sacrificed after post 24 hours and 30 days of irradiation. We assessed the oxidative stress parameter and mRNA profile (Liver, Kidney, spleen, and germ cells), sperm viability, and motility. The mRNA profile study established the network of combined cascade work during radiation to combat oxidative response and cell survival. The quantitative examination of mRNA uncovers unique critical changes in all mRNA levels in all the cases, particularly in germ cells. Recuperation was likewise seen in post 30 days radiation in the liver, spleen, and kidney followed by oxidative stress parameters, however not in germ cells. It proposes reproductive physiology is exceptionally sensitive towards radiation, even at the molecular level. It also suggests the suppression of Lef1/axin2 could be the main reason for permanent failure in the sperm function process. Post irradiation likewise influences the morphology of sperms. The decrease in mRNA level of Lef1, Axin2, survivin, Ku70 suggests radiation inhibits the Wnt canonical pathway and failure in DNA repair mechanism in a coupled manner. Likewise, the increase in BAX and BCL2 suggests apoptosis activation followed by the decreased expression of enzymatic antioxidants. In summary, controlled several interlinked cascades execute when body exposure to radiation may further be used in a study to counterpart and better comprehend medication focus on radiation treatment.
