Summary (written by the submitters)
Multiple myeloma (MM) is a malignant B cell dyscrasia characterized by the accumulation of clonal plasma cells (PC) within the bone marrow. Epigenetic factors are involved in MM initiation, progression, and occurrence of chemoresistance. Among them EZH2, the Polycomb Repressive Complex 2 (PRC2) catalytic subunit and NSD2 (MMSET), the target oncogene of t(4;14) primary translocation, are both associated with poor prognosis values and contribute to MM disease.

In this study, we identified a physical interaction between EZH2 and MMSET in MM. We used MMSET-depleted MM cells and MAK-683, an allosteric inhibitor of EZH2, to disrupt this interaction and understand its implication in MM biology and resistance to anti-MM drugs. Through its interaction with EZH2, MMSET regulates PRC2 nuclear localization in MM cells, promotes a particularly poor prognosis in MM patients, and modulates the expression of tumor-suppressor genes involved in p53 pathway. We also demonstrated that MAK-683 can interfere with this interaction and synergizes with conventional drugs used in MM treatment: Melphalan, an alkylating agent triggering DNA Damage Response (DDR); and Panobinostat, a Histone De-Acetylase (HDAC) inhibitor directedly regulating p53 acetylation and stability.

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 GSE242500_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1013595 and SRA study SRP458902. 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.
