Summary Paragraph Somatic variation contributes to biological heterogeneity by modulating cellular proclivity differentiate, expand, adapt, or die. While large-scale sequencing efforts have revealed the foundational role of somatic variants drive human tumor evolution, our understanding contribution mutations modulate fitness in non-malignant contexts remains understudied. Here, we identify a mosaic synonymous variant (m.7076A>G) mitochondrial DNA (mtDNA) encoded cytochrome c-oxidase...

Abstract Single-cell genomics technologies have accelerated our understanding of cell-state heterogeneity in diverse contexts. Although single-cell RNA sequencing (scRNA-seq) identifies many rare populations interest that express specific marker transcript combinations, traditional flow sorting limits ability to enrich these for further profiling, including requiring cell surface markers with high-fidelity antibodies. Additionally, studies require the isolation nuclei from tissue,...

Abstract Cell therapies have yielded durable clinical benefits for patients with cancer, but the risks associated development of from manipulated human cells are still being understood. For example, we currently lack a comprehensive understanding mechanisms neurotoxicity observed in receiving T cell therapies, including recent reports encephalitis caused by herpesvirus 6 (HHV-6) reactivation 1 . Here, via petabase-scale viral RNA data mining, examine landscape latent and demonstrate that...
