What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Homo sapiens (human)

21 samples: 7 conditions, mostly in triplicateGroups are read from the sample names, not from the paper. Check the list below.
Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.

Overlapping and distinct functions of SPT6, PNUTS, and PCF11 in regulating transcription terminationNucleic acids research · 2025
Summary (written by the submitters)
The histone chaperone and transcription elongation factor SPT6, integral to RNA Polymerase II (RNAPII) activity, also plays a crucial role in regulating transcription termination. In an attempt to identify the pathways employed by SPT6 in this regulation, we found that while SPT6 and its closest partner IWS1 interact and co-localize with RNAPII, their functions diverge significantly at gene termination sites.

Our data revealed that SPT6 depletion, unlike IWS1, results in extensive readthrough transcription, indicating that SPT6 independently regulates transcription termination. Further analysis identified that the cleavage and polyadenylation factor PCF11 and the phosphatase regulatory protein PNUTS collaborate with SPT6 in this process. These findings suggest that SPT6 may facilitate transcription termination by recruiting PNUTS and PCF11 to RNAPII. Additionally, SPT6 and PNUTS jointly restrict promoter upstream transcripts (PROMPTs), whereas PCF11 presence is essential for their activation in the absence of SPT6. This study elucidates the distinct and overlapping functions of SPT6, PCF11, and PNUTS in transcription termination, highlighting the pivotal role of SPT6 in ensuring proper transcription termination at the 5’ and 3’ ends of genes.

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 GSE272848_RAW.tar (it can run to tens of gigabytes).

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.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1139116 and SRA study SRP521586. Searching any of these in the dataset finder brings you back here.
