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
16 samples: 16 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)
Primary and acquired resistance to targeted therapy represent significant challenges to durable treatment responses in cancer. In lung cancer and other cancer types, allele- specific and pan-KRAS inhibitors offer new promise, but these are hampered by incomplete responses as well as genetic and non-genetic mechanisms of acquired resistance.

To model these mechanisms, we treat genetically engineered mouse models of KrasG12C-driven lung cancer with sotorasib, a KRASG12C inhibitor, until the emergence of drug resistance. The initial response to sotorasib was rapid, but incomplete. Residual tumor burden transcriptionally resembled the alveolar type II cell, phenocopying residual disease signatures identified in patients treated with EGFR inhibitors. After continued sotorasib treatment, we observed diverse mechanisms of drug resistance in vivo, including genetic MAPK reactivation and lineage transformation from adenocarcinoma to squamous histology. Focusing mechanistic studies on squamous transformation, we showed that expression of the basal transcription factor ∆Np63 is sufficient to rewire transformed alveolar organoids to a squamous state in vitro, conferring insensitivity to KRAS inhibition. In vivo, either ectopic expression of Sox2 or loss of Nkx2-1, which are tolerated during Kras-driven tumorigenesis, poised tumors for squamous lineage commitment upon KRAS inhibition. Squamous- transformed tumors did not exhibit evidence of KRAS/MAPK reactivation, underscoring the role for lineage transcription factors and histologic transformation in mediating oncogene independence.

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 GSE319597_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 PRJNA1417768 and SRA study SRP674210. Searching any of these in the dataset finder brings you back here.

Study design
16 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 16 sample titles: 16 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.
