Hypoxia Alters miRNAs Levels Involved in Non-Mendelian Inheritance of Autism Spectrum Disorder in Mice

We studied how different levels of neonatal hypoxia affect brain development, behavior, and ASD related molecular changes in mice, emphasizing the severity dependent effects and need for early intervention. Research studies link neonatal hypoxia to autism-related brain changes. Focus is shifting to repurpose drugs targeting neuroinflammation and neuro-immune dysfunction to prevent neuronal damage and long-term cognitive decline.

We used hypoxia chambers, qPCR, behavioral tracking, and microscope to track molecular and structural changes in neonatal brains. A key challenge is translating molecular changes like microRNA dysregulation into behavior due to ASD's complexity. Limitations include species differences, lack of sex-specific analysis, and difficult controlling hypoxia therapy.
