Summary (written by the submitters)
The deubiquitinase (DUB) Ubiquitin-Specific Protease 18 (USP18) is as an antineoplastic target. USP18 inhibitors are needed. To address this unmet need, we engineered an enzymatically active human recombinant USP18 protein for high-throughput screening. This found β-lapachone was an inhibitor of USP18-ISG15 activity. Independent β-Lapachone treatments of murine and human lung cancer cell lines statistically-significantly reduced proliferation and increased apoptosis.

Gain of USP18 expression opposed these effects. β-Lapachone treatments statistically- significantly repressed growth of H1299 human lung cancer xenografts in athymic mice and also in syngeneic mice transplanted with murine 344SQ lung cancers. β-Lapachone increased reactive oxygen species (ROS) but antineoplastic effects proceeded at concentrations having little ROS production. ROS scavenger treatments did not rescue anti-cancer effects, indicating an ROS-independent anti-neoplastic mechanism was engaged. To identify this an Interferon-Stimulated Response Element (ISRE) reporter assay was used. β-Lapachone treatment activated this reporter activity as expected for a USP18 inhibitor. β-Lapachone treatment increased global ISG15 conjugation. Proteomic analysis and immunoprecipitation assays revealed known and new ISG15ylated proteins. RNA sequencing of parental lung cancer cells engineered with or without gain of USP18 expression found differentially expressed genes and pathways after β-lapachone treatments. Taken together, β-lapachone is a novel USP18 inhibitor and cancer biology tool.

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 GSE318135_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 PRJNA1416776 and SRA study SRP671629. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 54 samples.

How we read this: 18 replicated groups read from 54 sample titles; they account for 54 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.
