(Submitter supplied) 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. more...

(Submitter supplied) We search for developmental changes specific to humans by examining gene expression profiles in the human, chimpanzee and rhesus macaque prefrontal and cerebellar cortex. In both brain regions, developmental patterns were more evolved in humans than in chimpanzees. The major human specific genes in prefrontal cortex was enriched in neuronal functions and regulated by several transcription factors, which were previously implicated in regulation of neuronal functions. more...

(Submitter supplied) We search for developmental changes specific to humans by examining gene expression profiles in the human, chimpanzee and rhesus macaque prefrontal and cerebellar cortex. In both brain regions, developmental patterns were more evolved in humans than in chimpanzees. To distinguish whether the human specific developmental pattern represent novel human-specific developmental patterns or a shift in the timing of the existing patterns, we measured mRNA expression patterns in macaque brains from prenatal to neonatal. more...

(Submitter supplied) We investigated molecular changes during human, chimpanzee, and rhesus macaque postnatal brain development at the transcriptome, proteome, and metabolome levels in two brain regions: the prefrontal cortex (PFC) that is involved in several human-specific cognitive processes, and the cerebellar cortex (CBC) that may be functionally more conserved. We find a nearly three-fold excess of human-specific gene expression changes in PFC compared to CBC. more...

(Submitter supplied) Gene expression changes determine functional differentiation during development and are associated with functional decline during aging. While developmental changes are tightly regulated, regulation of aging changes is not well established. To assess the regulatory basis of age-related changes and investigate the mechanism of regulatory transition between development and aging, we measured mRNA and microRNA expression patterns in brains of humans and rhesus macaques over the entire species’ lifespan. more...

(Submitter supplied) Among other factors, changes in gene expression on the human evolutionary lineage have been suggested to play an important role in the establishment of human-specific phenotypes. However, the molecular mechanisms underlying these expression changes are largely unknown. Here, we have explored the role of microRNA (miRNA) in the regulation of gene expression divergence between adult humans, chimpanzees and rhesus macaques, in two brain regions: prefrontal cortex and cerebellum. more...

(Submitter supplied) 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. more...

(Submitter supplied) we used RNA-Seq to quantify the RNA editing level at more than 8,000 previously annotated exonic A-to-I RNA editing sites in two brain regions - prefrontal cortex and cerebellum - of humans, chimpanzees and rhesus macaques. We observed substantial conservation of RNA editing levels between the brain regions, as well as among the three primate species. Evolutionary changes in RNA editing were nonetheless evident among the species. more...

(Submitter supplied) Differences in transcript splicing are well documented among tissues and between sexes in humans and other organisms. Further, splicing changes in selected genes have been reported in human and mouse brain development. Using high-throughput RNA sequencing we characterized the transcriptome-wide splicing changes occurring over the lifespan in the human brain. We found that in two brain regions, prefrontal cortex and cerebellum, as many as 37% of all expressed protein-coding multi-exon genes undergo significant splicing changes between birth and 98 years of age. more...

We analysed mouse RNA from cortex, cerebellum and liver from one individual. One RNA sample of 5µg from each of the three different tissues was processed according to the standard Affymetrix protocol and hybridized onto mouse gene expression arrays MG_U74Av2. more...
