Analysis of mRNA expression profiles in the cortex of male offspring following prenatal PM2.5 exposure. (a) Bar graphs showing the number of cortical DEGs at different windows. Chord plot depicting the relationship between DEGs and neurodevelopment-related biological process GO terms on PNDs 1 (b), 7 (c) and 21 (d). Neurodevelopment-related GO terms: biological process (e) and cellular component (f) in male offspring. n = 3 from 3 litters
