Postmortem human brain genomics in neuropsychiatric disorders — how far can we go?

Open access
Jaffe, Andrew E·2016·Current Opinion in Neurobiology

Abstract

Large-scale collection of postmortem human brain tissue and subsequent genomic data generation has become a useful approach for better identifying etiological factors contributing to neuropsychiatric disorders. In particular, studying genetic risk variants in non-psychiatric controls can identify biological mechanisms of risk free from confounding factors related to epiphenomena of illness. While the field has begun moving towards cell type-specific analyses, homogenate brain tissue with accompanying cellular profiles, can still identify useful hypotheses for more focused experiments, particularly when the dysregulated cell types are unknown. Technological advances, larger sample sizes, and focused research questions can continue to further leverage postmortem human brain research to better identify and understand the molecular etiology of neuropsychiatric disorders.

  • Few studies have examined the human brain for cell-type-specific differences in transcriptional states as a result of tissue handling or acute pre/postmortem processes.

    “However, few studies have examined the human brain for cell-type-specific differences in transcriptional states as a result of tissue handling or acute pre/postmortem processes12, and to our knowledge none have done so in a cell-type-specific manner using snRNA-seq.”

    From Dissection of artifactual and confounding glial signatures by single-cell sequencing of mouse and human brain (2022) · cites this paper as [12]

    The ‘Functional genomics in the human brain’ section says agonal state and the time between death and tissue processing can affect observed gene expression. ‘Moving towards interrogating individual cell populations’ describes cell-type-specific analysis of postmortem human brain as a challenge. Neither passage establishes that few studies have examined cell-type-specific transcriptional responses to tissue handling or acute pre/postmortem processes. (LLM, conf=0.82)

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.
