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)

12 samples: 12 samples, each with a distinct title — no replicated groupsGroups 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)
This study investigated the toxicological effects of two short-chain per- and polyfluoroalkyl substances (PFAS), including perfluorobutanoic acid (PFBA) and perfluorohexanoic acid (PFHxA), on the transcriptome of human nasal RPMI2650 cells. Gene annotation enrichment analysis highlighted neurofactor, synaptic, solute carrier, and ribosome signaling pathways in common pathways of widespread transcriptional changes in RPMI2650 cells.

Systematic analysis of RNA-seq data revealed that PFAS-treated RPMI2650 cells are encoded to participate in cell proliferation (H3C14), nerve regeneration (L1CAM, P2RY1), and solute transport (SLC17A7, LRRK2). TOP 10 GO analysis showed that DEGs was mainly concentrated in synaptic regulation, cell division correlation and solute carrier transport. For example, in the PFBA treatment group, typical terms include synaptic vesicular membrane (GO:0030672), synaptic transmission, glutaminergic energy (GO:0035249), and interneuronal synaptic transmission (GO:0007270), while in the PFHxA treatment group, DEGs is mainly enriched in nucleosomes (GO:0000786). Microtubule binding (GO:0008017) and neuronal differentiation in the central nervous system (GO:0021953). In KEGG enrichment pathway, PFBA-treated differential genes were mainly concentrated in synaptic related pathways, such as serotonergic synapses (hsa04726), glycerophospholipid metabolism (hsa00564), and GABAergic synapses (hsa04727). In addition to neuron-related pathways, PFHxA processing enrichedneurotransmitter related pathways such as sphingolipid biosynthesis-Globo and isoglobo series (hsa00603), GABaergic synapses (hsa04727), and neuroactive ligand-receptor interactions (hsa04080).

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 GSE267705_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 PRJNA1112434 and SRA study SRP508211. Searching any of these in the dataset finder brings you back here.

Study design
12 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 12 sample titles: 12 distinct titles with little repetition. 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.
