MSA: Scalable DNA methylation BeadChip for human trait screening [EM-seq]

ABSTRACT: We designed and introduced a new methylation array concentrating on human trait screening and discovery. The new MSA (Methylation Screening Array) leveraged the massive Infinium platform-based data from epigenome-wide association studies, combined with updated knowledge from the latest single cell and cell type-resolution whole genome methylome profiles, to achieve scalable screening of epigenetics-trait association in an ultra-high sample-throughput. Our design encompassed diverse human trait associations, including those with genetic, biological, and demographical variables, environmental exposures, and common human diseases such as neurodegenerative, genetic, cardiovascular, infectious, and immune diseases. We comprehensively evaluated this array's reproducibility, accuracy, and capacity in supporting 5-hydroxymethylation profiling and comprehensive cell-type deconvolution in diverse human tissues. Our first data using this platform uncovered dynamic chromatin and tissue contexts of DNA modification variations and genetic variants with human trait associations.

Phosphoproteomic analysis of IL-2 MSA and IL-12 MSA combination on T cell signaling

Project description:Engineered cytokine-based approaches for immunotherapy of cancer are poised to enter the clinic, with IL-12 being at the forefront. However, little is known about potential mechanisms of resistance to cytokine therapies. We found that orthotopic murine lung tumors were resistant to systemically delivered IL-12 fused to murine serum albumin (MSA, IL12-MSA) due to low IL-12R expression on tumor-reactive CD8+ T cells. IL2-MSA increased binding of IL12-MSA by tumor-reactive CD8+ T cells, and combined administration of IL12-MSA and IL2-MSA led to enhanced tumor-reactive CD8+ T cell effector differentiation, decreased numbers of tumor-infiltrating CD4+ regulatory T (Treg) cells, and increased survival of lung tumor-bearing mice. Predictably, the combination of IL-2 and IL-12 at therapeutic doses led to significant dose-limiting toxicity. Administering IL-12 and IL-2 analogs with preferential binding to cells expressing IL12rb1 and CD25, respectively, led to a significant extension of survival in mice with lung tumors while abrogating dose-limiting toxicity. These findings suggest that IL-12 and IL-2 represent a rational approach to combination cytokine therapy whose dose-limiting toxicity can be overcome with engineered cytokine variants.

Mapping genotype-expression associations in Heterogeneous Stock rat brains to advance behavioral genetics research [Orbitofrontal cortex]

Project description:Research into the genetic influences of impulsivity and reward motivated behavior relies heavily on outbred animal populations, including Heterogeneous Stock (HS) rats, for the genetic diversity necessary to identify genotype-trait associations. Many such associations have been detected, but it is not always clear which gene or other feature near the identified genomic location is functionally responsible for the association. Since these traits are in part mediated by gene expression, mapping the associations between genotype and gene expression in these animals will enable the discovery and deeper understanding of these trait associations. We therefore obtained genotypes and RNA-Seq gene expression for five brain regions from 88 HS rats and mapped expression quantitative trait loci (eQTLs) for each region. We identified cis-eQTLs in over 3,000 genes per brain region and validated their effect sizes using allele specific expression. This resource will enable new discoveries of the genetic influences of complex behavioral traits.
