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
Mus musculus (mouse)
Samples
8 samples: 2 × fn vs 2 × fkGroups 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)
Inactivation of fibroblast growth factor receptor 1 (FGFR1) in the mature osteoblast lineage using DMP1-CreER to target a floxed allele of Fgfr1 (FGFR1-CKO) results in extensive osteocyte death. To identify changes in gene expression in response to inactivation of Fgfr1 in vivo, femoral diaphyseal bone was harvested from 16-week-old Control (Fgfr1f/f) and FGFR1-CKO mice following 4 weeks exposure to Tamoxifen and subjected to bulk mRNA sequencing.
Read the full summary ↓
RNA sequencing demonstrated reduced expression of extracellular matrix (ECM) genes and neuronal regulatory genes, and differential expression of apoptosis regulatory genes. These data demonstrate that signaling through FGF receptor may be directly required for ECM remodeling and osteocyte projection formation, and loss of FGFR signaling causes retention of an osteoblast-like gene expression signature and apoptosis of bone-embedded cells.

This dataset
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 GSE316171_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 PRJNA1401751 and SRA study SRP661477. Searching any of these in the dataset finder brings you back here.

Study design
2 × fn vs 2 × fk

Supports a between-group comparison across 4 samples.

How we read this: 2 replicated groups read from 8 sample titles; they account for 4 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.
