A multimodal cell census and atlas of the mammalian primary motor cortex
ABSTRACT We report the generation of a multimodal cell census and atlas of the mammalian primary motor cortex (MOp or M1) as the initial product of the BRAIN Initiative Cell Census Network (BICCN). This was achieved by coordinated large-scale analyses of single-cell transcriptomes, chromatin accessibility, DNA methylomes, spatially resolved single-cell transcriptomes, morphological and electrophysiological properties, and cellular resolution input-output mapping, integrated through cross-modal computational analysis. Together, our results advance the collective knowledge and understanding of brain cell type organization: First, our study reveals a unified molecular genetic landscape of cortical cell types that congruently integrates their transcriptome, open chromatin and DNA methylation maps. Second, cross-species analysis achieves a unified taxonomy of transcriptomic types and their hierarchical organization that are conserved from mouse to marmoset and human. Third, cross-modal analysis provides compelling evidence for the epigenomic, transcriptomic, and gene regulatory basis of neuronal phenotypes such as their physiological and anatomical properties, demonstrating the biological validity and genomic underpinning of neuron types and subtypes. Fourth, in situ single-cell transcriptomics provides a spatially-resolved cell type atlas of the motor cortex. Fifth, integrated transcriptomic, epigenomic and anatomical analyses reveal the correspondence between neural circuits and transcriptomic cell types. We further present an extensive genetic toolset for targeting and fate mapping glutamatergic projection neuron types toward linking their developmental trajectory to their circuit function. Together, our results establish a unified and mechanistic framework of neuronal cell type organization that integrates multi-layered molecular genetic and spatial information with multi-faceted phenotypic properties
Analysis of Heritability and Shared Heritability Based on Genome-Wide Association Studies for 13 Cancer Types
Background: Studies of related individuals have consistently
demonstrated notable familial aggregation of cancer. We aim to estimate
the heritability and genetic correlation attributable to the additive
effects of common single-nucleotide polymorphisms (SNPs) for cancer at
13 anatomical sites.
Methods: Between 2007 and 2014, the US National Cancer Institute has
generated data from genome-wide association studies (GWAS) for 49 492
cancer case patients and 34 131 control patients. We apply novel mixed
model methodology (GCTA) to this GWAS data to estimate the heritability
of individual cancers, as well as the proportion of heritability
attributable to cigarette smoking in smoking-related cancers, and the
genetic correlation between pairs of cancers.
Results: GWAS heritability was statistically significant at nearly all
sites, with the estimates of array-based heritability, h(l)(2), on the
liability threshold (LT) scale ranging from 0.05 to 0.38. Estimating the
combined heritability of multiple smoking characteristics, we calculate
that at least 24% (95% confidence interval [CI] = 14% to 37%) and
7% (95% CI = 4% to 11%) of the heritability for lung and bladder
cancer, respectively, can be attributed to genetic determinants of
smoking. Most pairs of cancers studied did not show evidence of strong
genetic correlation. We found only four pairs of cancers with marginally
statistically significant correlations, specifically kidney and testes
(rho = 0.73, SE = 0.28), diffuse large B-cell lymphoma (DLBCL) and
pediatric osteosarcoma (rho = 0.53, SE = 0.21), DLBCL and chronic
lymphocytic leukemia (CLL) (rho = 0.51, SE = 0.18), and bladder and lung
(rho = 0.35, SE = 0.14). Correlation analysis also indicates that the
genetic architecture of lung cancer differs between a smoking population
of European ancestry and a nonsmoking Asian population, allowing for the
possibility that the genetic etiology for the same disease can vary by
population and environmental exposures.
Conclusion: Our results provide important insights into the genetic
architecture of cancers and suggest new avenues for investigation
A multimodal cell census and atlas of the mammalian primary motor cortex
none258Here we report the generation of a multimodal cell census and atlas of the mammalian primary motor cortex as the initial product of the BRAIN Initiative Cell Census Network (BICCN). This was achieved by coordinated large-scale analyses of single-cell transcriptomes, chromatin accessibility, DNA methylomes, spatially resolved single-cell transcriptomes, morphological and electrophysiological properties and cellular resolution input-output mapping, integrated through cross-modal computational analysis. Our results advance the collective knowledge and understanding of brain cell-type organization1-5. First, our study reveals a unified molecular genetic landscape of cortical cell types that integrates their transcriptome, open chromatin and DNA methylation maps. Second, cross-species analysis achieves a consensus taxonomy of transcriptomic types and their hierarchical organization that is conserved from mouse to marmoset and human. Third, in situ single-cell transcriptomics provides a spatially resolved cell-type atlas of the motor cortex. Fourth, cross-modal analysis provides compelling evidence for the transcriptomic, epigenomic and gene regulatory basis of neuronal phenotypes such as their physiological and anatomical properties, demonstrating the biological validity and genomic underpinning of neuron types. We further present an extensive genetic toolset for targeting glutamatergic neuron types towards linking their molecular and developmental identity to their circuit function. Together, our results establish a unifying and mechanistic framework of neuronal cell-type organization that integrates multi-layered molecular genetic and spatial information with multi-faceted phenotypic properties.openCallaway, Edward M.; Dong, Hong-Wei; Ecker, Joseph R.; Hawrylycz, Michael J.; Huang, Z.
