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)
Samples
36 samples: 12 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.

Human cytomegalovirus induces neuronal gene expression through IE1 for viral maturationNature communications · 2025
Summary (written by the submitters)
Human cytomegalovirus (HCMV) uniquely remodels host cells, generating a cytoplasmic viral-induced assembly compartment (vIAC) and a kidney-bean-shaped nucleus. How these stark morphology changes take place in the context of host gene regulation is still emerging. Here, we discovered that HCMV titers, but not virus particle numbers, were significantly reduced in the absence of the histone variant macroH2A1, indicating that macroH2A1 is essential for producing infectious progeny.

Because virion maturation and cellular remodeling are closely linked processes, we used confocal and electron microscopy to define structural changes in the host cell. We uncovered that HCMV-induced reorganization of the host nucleus, cytoskeleton, and endoplasmic reticulum does not occur in the absence of macroH2A1. Furthermore, we discovered using RNA-seq that while all viral genes were highly expressed in the absence of macroH2A1, many HCMV-induced host genes were not. Hundreds of these HCMV-induced macroH2A1-dependent host genes are associated with neuronal synapse formation and vesicle trafficking. Knock-down during infection of several HCMV-induced neuronal genes resulted in malformed vIACs and smaller plaques, establishing their importance to HCMV infection. Together, our findings demonstrate that HCMV manipulates host gene expression to hijack the dormant neuronal secretory pathway for proper virion maturation.

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 GSE272267_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 PRJNA1135976 and SRA study SRP519973. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 36 samples.

How we read this: 12 replicated groups read from 36 sample titles; they account for 36 of them. 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.
