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.

Samples
30 samples: 10 conditions, mostly in triplicateGroups 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)
Multiple myeloma (MM) provides a permissive tumor microenvironment (TME), supporting tumor cell growth and dissemination, and conferring therapy resistance. RNAseq in the human MM cell lines RPMI 8226 and MM.1S after knockdown of NOTCH1 (N1) and NOTCH2 (N2) was performed to identify genes and pathways that are specifically regulated through NOTCH signaling and contribute to the permissive TME.
Read the full summary ↓
GSEA confirmed previous findings that NOTCH signaling stimulates the expression of cytokines involved in inflammation, defining an immunosuppressive TME promoting cell viability and migration in MM. Furthermore, a downregulation of “receptor signaling pathway via JAK-STAT” after N1 or N2 knockdown and “regulation of bone resorption” and “regulation of bone remodeling” after N1 knockdown was found. Moreover, our results showed that the expression of multiple core matrisome and matrisome-associated proteins was altered, revealing N1 and N2 as key regulators of extracellular matrix (ECM) remodeling in the bone marrow niche. This process destroys the ECM abundance and integrity and has prognostic relevance. The identification of novel ECM targets will help to develop new treatment strategies that preserve the ECM in a less permissive niche.

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 GSE221038_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 PRJNA912649 and SRA study SRP413232. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 30 samples.

How we read this: 10 replicated groups read from 30 sample titles; they account for 30 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.
