Paper
MYC Family Amplification Dictates Sensitivity to BET Bromodomain Protein Inhibitor Mivebresib (ABBV075) in Small-Cell Lung CancerMolecular cancer research : MCR · 2024
Summary (written by the submitters)
Small-cell lung cancer (SCLC) accounts for nearly 15% of all lung cancers. Although patients respond to first line therapy readily, rapid relapse is inevitable with few treatment options in the second line setting. Here, we describe SCLC cell lines harboring amplification of MYC and MYCN, but not MYCL1 nor non-amplified MYC cell lines, exhibit superior sensitivity to treatment with the pan-BET bromodomain protein inhibitor Mivebresib (ABBV-075).
Read the full summary ↓
Silencing MYC and MYCN partially rescued SCLC cell lines harboring these respective amplifications from the anti-proliferative effects of mivebresib. Furthermore, the activity of mivebresib in SCLC cell lines occurs primarily through BRD2, rather than BRD4. Further characterization of genome-wide binding of MYC, MYCN, and MYCL1 uncovered unique enhancer and epigenetic preferences. Our study suggests that chromatin landscapes could establish cell states with unique gene expression programs, conveying sensitivity to epigenetic inhibitors such as mivebresib.

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 GSE230649_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 PRJNA962070 and SRA study SRP434628. Searching any of these in the dataset finder brings you back here.
