Single-cell RNAseq reveals the pro-regenerative role of senescent FAPs in muscle regeneration

Abstract Muscle regeneration is associated with transient induction of cellular senescence. However, the role of senescence in muscle regeneration of young mice remains unclear. Using a mouse model deficient in both Cdkn1a and Cdkn2a, we find that a marked reduction in senescent cells correlates with delayed muscle regeneration. Single-cell RNA…

Using deep long-read RNAseq in Alzheimer’s disease brain to assess medical relevance of RNA isoform diversity

Abstract Due to alternative splicing, human protein-coding genes average over eight RNA isoforms, resulting in nearly four distinct protein coding sequences per gene. Long-read RNAseq (IsoSeq) enables more accurate quantification of isoforms, shedding light on their specific roles. To assess the medical relevance of measuring RNA isoform expression, we sequenced…

They Discovered How A Carnivorous Fungus Can Trap And Digest Worms

A new analysis sheds light on the molecular processes that occur when a carnivorous species of fungus known as Arthrobotrys oligospora detects, traps and ingests a worm. The a. oligospora’ usually obtains its nutrients from decaying organic matter, but hunger and the presence of nearby worms prompts it to build…
