Developmental patterns in the hippocampal transcriptome of the vervet monkey
Elucidating the developmental patterns of gene expression across brain regions is a critical step toward understanding brain development and disease. We previously studied the transcriptome of multiple brain regions and peripheral tissues across development in the vervet monkey, and identified transcripts related to hippocampal size in 59 animals across 10 developmental timepoints, ranging between 7 days to 9 years of age. Here, we extended this analysis with a focus on transcriptomic changes in hippocampus across early development in vervet neonates and infants under 1 year of age. We combined this dataset with the previously analyzed data. We identified groups of transcripts with age-related patterns, which correlated well with existing human resources. Additionally, expression quantitative trait locus (eQTL) analysis identified two further genes, RAB31 and CHMP1B, associated with hippocampal volume, refining the previously identified locus. This dataset provides unique developmental expression data in the hippocampus of a non-human primate, and expands our catalog of local and distant eQTL in this brain region. Overall design: Examination of developmental transcriptome changes in vervet hippocampus.
