Gene expression data from primate postnatal brain development - superior frontal gyrus

ABSTRACT: In development, timing is of the utmost importance, and the timing of various developmental processes are often changed during evolution. During human evolution sexual maturation has been delayed relative to other primates and this may have played a critical role for both the increase of human brain size and the rise of human-specific cognitive traits . We measured the timing of gene expression changes in the superior frontal gyrus region of the brains of humans, chimpanzees, and rhesus macaques throughout postnatal development. Keywords: Age series

Keywords: Age series Human, chimpanzee and rhesus macaque post-mortem brain samples from the superior frontal gyrus region of the prefrontal cortex were collected. The age ranges of the individuals in all three species covered the respective species' postnatal maturation period from infancy to adulthood. RNA extracted from the dissected tissue was hybridized to Affymetrix® Human Gene 1.0 ST arrays.

Gene expression changes during primate postnatal brain development

Project description:In development, timing is of the utmost importance, and the timing of various developmental processes are often changed during evolution. During human evolution sexual maturation has been delayed relative to other primates and this may have played a critical role for both the increase of human brain size and the rise of human-specific cognitive traits . We measured the timing of gene expression changes in the brains of humans, chimpanzees, and rhesus macaques throughout postnatal development. Human, chimpanzee and rhesus macaque post-mortem brain samples from the dorsolateral prefrontal cortex region were collected. The caudate nucleus region was additionally sampled for humans. The age ranges of the individuals in all three species covered the respective species' postnatal maturation period from infancy to young adulthood. RNA extracted from the dissected tissue was hybridized to Affymetrix® U133-plus2.0 GeneChip® arrays.

Quantification of gene expression from primate tissue samples

Project description:We have quantified gene expression in five tissues (brain, heart, kidney, liver and testis) from humans, chimpanzees and rhesus macaques using the Illumina NlaIII Digital Gene Expression (DGE) protocol. This dataset extends a previous microarray study by Khaitovich et al. (Khaitovich et al. 2005) with the rhesus macaque outgroup and complements other previously generated tissue transcriptome profiles from primates (Enard et al. 2002; Khaitovich et al. 2006; Somel et al. 2009; Babbitt et al. 2010; Blekhman et al. 2010; Wetterbom et al. 2010). contributor: Max Planck Institute for Evolutionary Anthropology, Deutscher Platz 6, D-04103 Leipzig, Germany Samples were obtained from brain (pre-frontal cortex), heart, kidney, liver, and testis tissues of male humans, chimpanzees and rhesus macaques. Illumina NlaIII DGE libraries for all samples were generated in tissue batches, randomizing species in library preparation and sequencing. Human samples originate from different, probably unrelated, individuals for each tissue. For chimpanzees and rhesus macaques the libraries for all tissues come from the same set of individuals and among these are individuals related at the half- and full-sibling level. Due to limited access to samples, the analysis could not be limited to individuals of similar age. Human individuals vary between 5 and 88 years of age, chimpanzees between 6 years and 35 years of age and rhesus macaques between 3 and 9 years of age.

MicroRNA expression in primate postnatal brain through lifespan

Project description:While multiple studies have reported the accelerated evolution of brain gene expression in the human lineage, the mechanisms underlying such change remain poorly understood. Here we address this issue from a developmental perspective, by analyzing mRNA and microRNA (miRNA) expression in two brain regions within macaques, chimpanzees and humans throughout their lifespan. We find that developmental profiles of trans-regulators, such as miRNA, as well as their target genes, show the fastest rates of human-specific evolutionary change. Changes in expression of a few key regulators may be a major driving force behind human brain evolution. Human, chimpanzee and rhesus macaque post-mortem brain samples from the prefrontal cortex and cerebellar cortex were collected. The age ranges of the individuals in all three species covered the respective species' postnatal maturation period from infancy to old adulthood. RNA extracted from the dissected tissue was hybridized to B72.

Genome-wide inter-primate comparison of gene expression profiles in multiple tissues

Project description:Regulatory changes have long been hypothesized to play an important role in primate evolution. To identify adaptive regulatory changes in humans, we performed a genome-wide survey for genes whose regulation evolves under natural selection. To do so, we used a novel multi-species microarray to measure gene expression levels in livers, kidneys, and hearts from six humans, chimpanzees, and rhesus macaques.
