Differential expression analysis in single-cell transcriptomics enables the dissection of cell-type-specific responses to perturbations such as disease, trauma, or experimental manipulations. While many statistical methods are available identify differentially expressed genes, principles that distinguish these and their performance remain unclear. Here, we show relative is contingent on ability account for variation between biological replicates. Methods ignore this inevitable biased prone false discoveries. Indeed, most widely used can discover hundreds genes absence differences. To exemplify principles, exposed true discoveries injured mouse spinal cord.

Abstract RNA sequencing (RNAseq) can reveal gene fusions, splicing variants, mutations/indels in addition to differential expression, thus providing a more complete genetic picture than DNA sequencing. This most widely used technology genomics tool box has evolved from classic bulk (RNAseq), popular single cell (scRNAseq) newly emerged spatial (spRNAseq). Bulk RNAseq studies average global scRNAseq investigates biology up 20,000 individual cells simultaneously, while spRNAseq ability dissect activities spatially, representing next generation of article highlights these technologies, characteristic features and suitable applications precision oncology.

Nociceptors are specialized sensory neurons that detect damaging or potentially stimuli and found in the dorsal root ganglia (DRG) trigeminal ganglia. These critical for generation of neuronal signals ultimately create perception pain. also primary targets treating acute chronic Single-cell transcriptomics on mouse nociceptors has transformed our understanding pain mechanisms. We sought to generate equivalent information human with goal identifying transcriptomic signatures nociceptors, species differences potential drug targets. used spatial molecularly characterize transcriptomes single DRG from eight organ donors. identified 12 clusters neurons, 5 which C as well 1 low-threshold mechanoreceptors (LTMRs), Aβ nociceptor, 2 Aδ, Aβ, proprioceptor subtypes.

Short-read RNA sequencing and long-read each have their strengths weaknesses for transcriptome assembly. While short reads are highly accurate, they rarely able to span multiple exons. Long-read technology can capture full-length transcripts, but its relatively high error rate often leads mis-identified splice sites. Here we present a new release of StringTie that performs hybrid-read By taking advantage the both long reads, assembly with is more accurate than only or short-read assembly, on some datasets it double number correctly assembled while obtaining substantially higher precision data alone. demonstrate improved accuracy simulated real from Arabidopsis thaliana , Mus musculus human. We also show correcting prior being faster. freely available as open source software at https://github.com/gpertea/stringtie .

Alternative splicing is a tightly regulated process whereby non-coding sequences of pre-mRNA are removed and protein-coding segments assembled in diverse combinations, ultimately giving rise to proteins with distinct or even opposing functions. In the past decade, whole genome/transcriptome sequencing studies revealed high complexity regulation, which occurs co-transcriptionally influenced by chromatin status mRNA modifications. Consequently, profiles both healthy malignant cells display diversity alternative was shown be widely deregulated multiple cancer types. particular, mutations regulatory sequences, regulators modifiers, as well differential expression factors important contributors pathogenesis. It has become clear that these aberrations contribute many facets cancer, including oncogenic transformation, progression, response anticancer drug treatment resistance therapy. this respect, perturb broad spectrum relevant genes involved uptake/metabolism (i.e. SLC29A1, dCK, FPGS, TP), activation nuclear receptor pathways GR, AR), regulation apoptosis MCL1, BCL-X, FAS) modulation immunotherapy (CD19).
