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)
Topic
Cervical cancerThis series is part of our curated briefing on it.
Samples
10 samples: 5 × primary cervical cancer-R vs 5 × primary cervical cancer-RSGroups 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)
Studies have demonstrated the correlation between kallikrein-related peptidase 5 (KLK5) and cervical cancer prognosis, but studies on the correlation between KLK5 and radiation resistance are rare. Therefore, we aimed to investigate the role of high KLK5 expression in improving radiation resistance in cervical cancer and the underlying mechanisms.

Samples from 29 patients with cervical cancer who received definitive radiotherapy without surgical treatment and other antineoplastic treatments (2014–2016) were analyzed. The patients were divided into the radiotherapy-sensitive (RS) group (18 patients without local recurrence and distant metastasis within 3 years after initial treatment) and the radiotherapy-resistant (RR) group (11 patients with uncontrolled conditions with radiotherapy, local recurrence, or distant metastasis within 3 years after initial treatment). We used high-throughput gene sequencing to detect radiosensitivity-related factors. We found that the expression of KLK5 in the RR group was higher than that in the RS group, and this result was associated with poor outcomes after radiotherapy as patients developed distant metastasis and showed recurrence at 2–3 years of follow-up. Besides, a high KLK5 expression enhances radiation resistance, indicating that, with further research, KLK5 may be used to develop novel molecular target-specific modulators for anti-cervical cancer therapy, acting as a prognostic agent in personalized precision medicine for cancer.

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 GSE189721_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 PRJNA784279 and SRA study SRP348261. Searching any of these in the dataset finder brings you back here.

Study design
5 × primary cervical cancer-R vs 5 × primary cervical cancer-RS

Supports a between-group comparison across 10 samples.

How we read this: 2 replicated groups read from 10 sample titles; they account for 10 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.
