Method for establishing and verifying a hydrogen peroxide-induced mouse autism model

This invention discloses a method for establishing and validating a hydrogen peroxide-induced mouse autism model, relating to the field of medical biotechnology. The method for establishing the hydrogen peroxide-induced mouse autism model includes the following steps: injecting the hydrogen peroxide solution into the peritoneal cavity of pregnant mice to induce hydrogen peroxide, resulting in offspring mice with hydrogen peroxide induction, i.e., the mouse autism model. This invention uses near-peritoneal injection of hydrogen peroxide during the gestational period of the mother mouse, inducing oxidative stress in both the pregnant mother mouse and the offspring embryo through hydrogen peroxide alone, without causing a significant immune response in the mother mouse. Therefore, an oxidative stress-specifically induced ASD mouse model is formed. The resulting ASD offspring mice exhibit significant ASD phenotypes but do not show obvious motor impairment.
