Fetal neurodevelopmental spatio-temporal dynamic transcriptional landscape of maternal insult-induce autism spectrum disorder risk.
Biochemical and biophysical research communications(2022)
摘要
Maternal insults during pregnancy induces an increased risk of autism spectrum disorders (ASD) in offspring, but the neuropathological changes in this process remains not to be established. To shed light on this, the transcriptome datasets of maternal blood samples with children later diagnosed with ASD and typical development, and tissue samples of multiple brain regions from ASD patients and human neurodevelopment were conducted to identify the non-chasm differentially expressed genes (DEGs) to generate the spatio-temporal dynamic change. Combined enrichment and interaction network analysis revealed that non-chasm DEGs with similar expression trajectories in the same brain regions, were involved in neural, immune and metabolic GO functions and KEGG pathways, respectively, suggesting that did not performed exactly the same functions. Interestingly, our results found that non-chasm DEGs in frontal cortex and temporal cortex were associated with COVID-19, suggesting that as an environmental risk factor COVID-19 affects an increased risk of ASD.
