Common human genetic variants of APOE impact murine COVID-19 mortality
Lung tissue from knock-in mice expressing common variants of human APOE (APOE2, APOE3 and APO4) showed differences in gene expression that causally impacted the outcome of COVID-19 infection. APOE2 and APOE4 knock-in mice had increased disease progression and mortality relative to APOE3 knock-in mice. Human data from the UK Biobank supports the finding that genetic variation in APOE partially explains the variation in severity of COVID-19 disease outcomes.

High-quality functional association networks inferred from scRNA-seq and proteomics data

Mikaela Koutrouli, Pau Piera Líndez, Robbin Bouwmeester, Simon Rasmussen, Lennart Martens, Lars Juhl Jensen
WT PBMCs
Introduces FAVA, a novel analysis method to handle large-scale scRNA-seq and proteomic data, predict high-confidence functional associations, and provide good coverage for understudied proteins. Performance was evaluated using freely available proteomic and PBMC scRNA-Seq datasets.

Human iPS cell-derived sensory neurons can be infected by SARS-CoV-2 strain WA1/2020 as well as variants delta and omicron

Anthony Flamier, Punam Bisht, Alexsia Richards, Danielle Tomasello, Rudolf Jaenisch
WT Mini Human iPS
In COVID-19-infected human sensory neurons, scRNA-seq was critical in revealing that sensory neurons can be infected by SARS-CoV-2 but are unable to produce new viruses. This may have implications for understanding the infection’s long-term impact on the peripheral nervous system.

Notch Inhibition Promotes Regeneration and Immunosuppression Supports Cone Survival in a Zebrafish Model of Inherited Retinal Dystrophy

Joseph Fogerty, Ping Song, Patrick Boyd, Sarah E. Grabinski, Thanh Hoang, Adrian Reich, Lauren T. Cianciolo, Seth Blackshaw, Jeff S. Mumm, David R. Hyde, and Brian D. Perkins
WT Zebrafish Retina
In a zebrafish model of progressive retinal degeneration, inflammation alone was not sufficient to trigger Müller glia reprogramming into multipotent retinal progenitors. Single cell RNA-seq showed that notch signaling remained active with progressive degeneration in contrast to what has been seen previously with acute injury.

Single-nuclei transcriptomics of mammalian prion diseases identifies dynamic gene signatures shared between species

Athanasios Dimitriadis, Fuquan Zhang, Thomas Murphy, Thomas Trainer, Zane Jaunmuktane, Christian Schmidt, Tamsin Nazari, Jacqueline Linehan, Sebastian Brandner, John Collinge, Simon Mead, and Emmanuelle Viré
WT Mouse Brain
Gene expression studies on the brains of mice with prion disease identified shared gene signatures with human prion disease, providing clues to molecular mechanisms. Incorporation of a protein denaturation step allowed the removal of the samples from a BSL-3 to a BSL-2 lab for the library preparation and sequencing steps.

Directed Differentiation of Human iPSCs to Functional Ovarian Granulosa-Like Cells via Transcription Factor Overexpression

Merrick Pierson Smela, Christian Kramme, Patrick Fortuna, Jessica Adams, Edward Dong, Mutsumi Kobayashi, Garyk Brixi, Emma Tysinger, Richie. E. Kohman, Toshi Shioda, Pranam Chatterjee, and George M. Church
WT Mega Human iPSCs
Two transcription factors required for the development of ovarian granulosa cells, (a necessary and previously lacking component of human ovary organoids) were identified. Human iPSCs were induced to differentiate into human ovary organoids, whose identities were confirmed based on differential gene expression.

Mapping and modeling the genomic basis of differential RNA isoform expression at single-cell resolution with LR-Split-seq

Elisabeth Rebboah, Fairlie Reese, Katherine Williams, Gabriela Balderrama-Gutierrez, Cassandra McGill, Diane Trout, Isaryhia Rodriguez, Heidi Liang, Barbara J. Wold, and Ali Mortazavi
WT Cell Lines
Full length transcript isoforms were identified using long-read sequencing on the PacBio platform with a protocol modification described as LR-Split-Seq. Applying this approach in mouse muscle cell lines, previously known and novel alternatively spliced transcript isoforms were detected.
