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.

Summary (written by the submitters)
Glioblastoma rapidly acquires resistance to conventional genotoxic therapy. This behavior is closely associated with the enhancement of stem-cell-like character during disease progression. Farnesyl diphosphate synthase (FDPS) plays an important role in maintaining such stem-cell-like features. This finding has stimulated interest in FDPS as neuro-oncology drug target; however, the lack of CNS-permeable inhibitors has hampered further development.
Read the full summary ↓
In this study, we explored the utility of taxodione, a diterpenoid described as an FDPS inhibitor and predicted to penetrate the blood-brain-barrier. The effects of taxodione were compared to its congener 7-(2-oxohexyl)-taxodione and a known FDPS inhibitor in glioblastoma cells. Taxodione was the only treatment that significantly reduced the size of tumor spheroids in a temporal and dose-dependent manner. This activity was linked to FDPS inhibition and transcriptional downregulation of other Mevalonate Pathway genes. Consistent with this putative mechanism-of-action, taxodione sensitized glioblastoma cells to nanomolar concentrations of paclitaxel.

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 GSE299445_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 PRJNA1274459 and SRA study SRP591072. Searching any of these in the dataset finder brings you back here.

Study design

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 sample titles; they account for 12 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.
