scRepli-RamDA-seq: a multi-omics technology enabling the analysis of gene expression dynamics during S-phaseNature communications · 2025
Summary (written by the submitters)
Single-cell sequencing has advanced our understanding of cell-type diversity and heterogeneity. However, existing single-cell multi-omics methods lack DNA data resolution and full-length total RNA detection. Here, we introduce single-cell (sc)Repli-RamDA-seq (scRR-seq), a novel multi-omics method that enables high-resolution DNA replication profiling and full-length total RNA sequencing from the same single cell, made possible by the clean separation of DNA and RNA.
Read the full summary ↓
scRR-seq generates DNA replication and RNA sequencing data comparable to individually obtained scRepli-seq and scRamDA-seq data, respectively. scRR-seq also allows one to tell the cell-cycle stage of a given S-phase cell and detects copy-number variation (CNV) in non-S-phase cells. scRR-seq outperforms other scRNA-seq methods in the number of transcripts identified and full-length total RNA detection. Furthermore, scRR-seq allowed haplotype-specific analysis and the identification of novel S-phase markers. Taken together, scRR-seq is a robust single-cell multi-omics method with promising potential for comprehensive genome and transcriptome analysis.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE278944_RAW.tar (it can run to tens of gigabytes).

All supplementary files ↗ Whole study · RAW.tar ↓
3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

Raw reads on ENA ↗

What the files usually look like: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1169807 and SRA study SRP537018. Searching any of these in the dataset finder brings you back here.

Study design
26 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 26 sample titles: 26 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
