Long-read RNA-seq resolves isoform-level and context-specific regulatory architecture of complex traits in cattle
Traditional short-read RNA-seq lacks the resolution to fully capture full-length isoforms and complex alternative splicing, leaving a "missing regulation" gap in existing molecular atlases. Here, we present a population-scale, multi-omics dissection of bovine complex traits using matched deep whole-genome sequencing (30), long-read (ONT) and short-read RNA-seq, as well as metabolome data from 432 dairy cows across four distinct lactation stages. We expanded the bovine transcript atlas with...
Auditable recovery of single-cell RNA-seq zeros with SPARE
In Single-cell RNA-seq, observed zeroes are the mix between biological absence and technical limitations. However, current evaluation metrics fail to distinguish between these two states, focusing on reconstruction accuracy rather than the biological validity of edits. We introduce SPARE, a partition-aware framework that audits the imputation process by cataloging observed zeros as edited, unchanged, or marker-vetoed prior to sequence reconstruction.
reComBat-seq: Regularized negative binomial regression for batch-effect correction in underdetermined transcriptomics datasets
Motivation: Batch effect correction is essential for the integration of large-scale transcriptomics datasets such as single-cell RNA-seq or multi-study bulk RNA-seq datasets for reducing technical noise that may mask biological signal. Existing correction methods, either do not produce count data output which is crucial for state-of-the-art downstream analyses such as differential expression analysis or fail to converge in underdetermined study designs. Results: We present reComBat-seq, a...
Multi-omics analysis reveals chromatin and transcriptomic remodeling in hippocampal CA1 following adolescent social isolation
Social isolation (SI) during adolescence is associated with long-term vulnerability to psychiatric disorders; however, its effect on the hippocampal epigenome and transcriptome remains unclear. Here, we performed integrative ATAC-seq and RNA-seq of the hippocampal CA1 region using an adolescent mouse SI model, combined with single-cell RNA-seq reference mapping and cell type deconvolution. ATAC-seq identified SI-associated alterations in chromatin accessibility, including an increase in...
Longitudinal RNA Seq analyses reveal the prominent role of Vagococcus in broiler meat spoilage microbiome
Background Raw broiler meat products are highly perishable, and microbial activity is the main factor limiting their shelf lives. The spoilage microbiomes of broiler meat products have been studied mainly using traditional culturing methods and 16S rRNA gene amplicon sequencing, neither of which can show the activity of whole microbiome. Previous metatranscriptomic research of broiler spoilage has also remained limited to specific spoilage organisms rather than entire microbiomes.
SIRT7 regulates dosage compensation and safeguards the female X chromosome
Abstract Sirtuins are deacetylases implicated in stress responses and longevity in mammals1,2. Although their differential impact on disease for the two sexes has been noted3,4,5,6,7, the underlying reasons are unclear. Here, using Sirt7 as a model in mice, we examine the mechanisms leading to sex differences and find that Sirt7−/− female mice have decreased fitness throughout their lifespan.
Imputed graph-genotyped structural variants identify regulatory haplotypes associated with gene expression in Atlantic salmon
Structural variants (SVs) can affect gene regulation, but they are difficult to include in expression genetic studies when large RNA-seq cohorts lack whole-genome sequencing. This is common in non-human and non-model systems, where whole-genome sequencing at population scale remains costly. As a result, expression quantitative trait locus (eQTL) studies often rely on single nucleotide polymorphism (SNP) markers.
Molecular glue degraders of HuR suppress BRAF-mutant colorectal cancer
Abstract BRAF gain-of-function mutations, particularly BRAF(V600E), affect roughly 10% of all patients with colorectal cancer (CRC), and portend poor prognosis with limited therapeutic interventions. BRAF inhibitors such as encorafenib are ineffective due to MAPK pathway reactivation driven by BRAF dimerization. Combined inhibition of BRAF and EGFR, although approved therapies, results in short survival benefits and frequent treatment resistance and relapse1,2,3.
Single-cell multimodal profiling of pan-cancer cell lines uncovers gene regulatory principles underlying intrinsic cell states and environmental features
Cancer arises from extensive genetic and epigenetic alterations that reshape chromatin, transcriptional regulation, and malignant cell states. To systematically chart cancer-intrinsic regulatory programs, we constructed a pan-cancer single-cell transcriptomic and epigenomic atlas encompassing 60 human cell lines representing 16 tissue origins and 20 cancer types, comprising 240,957 single-nucleus RNA-seq and 223,347 single-nucleus ATAC-seq profiles. Integrative analyses revealed extensive...
Anthocyanin-associated cellular programs underlying terroir variation in Cabernet Sauvignon grape berry revealed by SEED-based deconvolution
Plant tissues consist of diverse cell populations that collectively contribute to development, metabolism, environmental responses, and phenotype formation. Although single-cell and single-nucleus RNA sequencing have greatly advanced the study of plant cellular heterogeneity, their application to large sample cohorts remains limited by cost, technical complexity, tissue dissociation constraints, and throughput. In contrast, bulk RNA-seq datasets have accumulated extensively across plant...
