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
16 samples: 4 × GBM12 cells, PBS vs 4 × GBM12 cells, OncoD vs 4 × GBM28 cells, PBS vs 4 × GBM28 cells, OncoDGroups 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.

Summary (written by the submitters)
Oncolytic HSV-1 derived viruses are being developed for cancer treatment. Here we describe the isolation of a novel strain of HSV-1, and its engineering to safely harness it as an oncolytic therapeutic. This strain (UT1a) was isolated from a de-identified consented patient biorepository. CRISPR-Cas9-based recombination was utilized to insert bacterial artificial chromosome (BAC) genes into the viral UL39 and UL40 locus resulting in the deletion of both large and small subunits of the viral ribonucleotide reductase (RR).

Subsequent deletion of viral RL1 genes encoding the neurovirulence factor ɣ34.5, resulted in OncoDelta (OncoD), a virus deleted for UL39, UL40 and both copies of RL1. OncoD retained tumor cell specific cytotoxicity and replication, was safe and non-toxic in intracranial injections in naïve mice up to doses of (5 x 106), maximal injectable dose OncoD and showed significant anti-tumor immune activating potential in multiple tumor models. Transcriptome profiling of OncoD showed that it impaired DNA damage repair pathways and hence synergized with radiation to improve therapeutic response in vitro and in vivo.

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 GSE288846_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 PRJNA1219598 and SRA study SRP561772. Searching any of these in the dataset finder brings you back here.

Study design
4 × GBM12 cells, PBS vs 4 × GBM12 cells, OncoD vs 4 × GBM28 cells, PBS vs 4 × GBM28 cells, OncoD

Supports a between-group comparison across 16 samples.

How we read this: 4 replicated groups read from 16 sample titles; they account for 16 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.
