Abstract

Previous investigations have combined transcriptional and genetic analyses in human cell lines, but few have applied these techniques to human neural tissue. To gain a global molecular perspective on the role of the human genome in cortical development, function and ageing, we explore the temporal dynamics and genetic control of transcription in human prefrontal cortex in an extensive series of post-mortem brains from fetal development through ageing. We discover a wave of gene expression changes occurring during fetal development which are reversed in early postnatal life. One half-century later in life, this pattern of reversals is mirrored in ageing and in neurodegeneration. Although we identify thousands of robust associations of individual genetic polymorphisms with gene expression, we also demonstrate that there is no association between the total extent of genetic differences between subjects and the global similarity of their transcriptional profiles. Hence, the human genome produces a consistent molecular architecture in the prefrontal cortex, despite millions of genetic differences across individuals and races. To enable further discovery, this entire data set is freely available (from Gene Expression Omnibus: accession GSE30272; and dbGaP: accession phs000417.v1.p1) and can also be interrogated via a biologist-friendly stand-alone application (http://www.libd.org/braincloud).

  • Initial brain-specific functional genomics work provided greater insight but could be enhanced with larger sample sizes.

    “Initial work focusing on brain-specific functional genomics has provided greater insight but could be enhanced with larger sample sizes (11, 12).”
  • Recent studies had analysed transcriptional dynamics during human brain development only in a small number of relatively coarse brain regions.

    “Several important recent studies have begun to analyse transcriptional dynamics during human brain development4, 5, although only in a small number of relatively coarse brain regions.”
  • The high degree of similarity between the two brains is suggestive of a strong underlying common blueprint for the human brain transcriptome and is consistent with other recent studies of human neocortical gene expression.

    “this high degree of similarity is suggestive of a strong underlying common blueprint for the human brain transcriptome and is consistent with other recent studies of human neocortical gene expression4, 5”
  • Prior studies have examined only a restricted subset of prenatal human brain regions and cortical layers.

    “Several recent studies have assayed a limited set of brain structures1,3–5 and layers2 from prenatal human brain.”

    From Transcriptional landscape of the prenatal human brain (2014) · cites this paper as [1]

  • CMC eQTLs captured most eQTLs found in other independent brain samples, with replication π1 values of 0.98 for GTEx v6 and 0.70-0.93 for several microarray datasets.

    “Considering microarray-based eQTLs from the Harvard Brain Bank 15, BrainCloud16, NIH17, and the UK Brain Expression Consortium (UKBEC)18, we estimated π1 to be 0.75, 0.70, 0.79, and 0.93, respectively, indicating that our results captured most eQTLs found in other independent samples.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
