Summary (written by the submitters)
Focal amplifications of 3p13-3p14 occur in about 10% of melanoma and are associated with poor prognosis. The melanoma-specific oncogene MITF resides at the epicenter of this amplicon1. However, whether other loci present in this amplicon also contribute to melanomagenesis is unknown. Here we show that the recently annotated long non-coding RNA gene LINC01212 is consistently co-gained with MITF.

In addition to being amplified, LINC01212 is a target of the lineage-specific transcription factor SOX10 and, consequently, it is expressed in more than 90% of human melanomas, but not in normal adult tissues. Whereas exogenous LINC01212 functions in trans to increase melanoma clonogenic potential LINC01212 knock-down dramatically decreases the viability of melanoma cells irrespective of their transcriptional cell state, BRAF, NRAS or TP53 status, diminishes melanoma growth and increases their sensitivity to MAPK-targeting therapeutics both in vitro and in patient-derived melanoma xenograft mouse models. Mechanistically, LINC01212 functions as a lineage addiction oncogene by interacting with and modulating the cellular localization and function of two proteins, XRN2 and p32, involved in nucleolar and mitochondrial rRNA processing, ribosome biogenesis and protein synthesis. LINC01212 targeting, especially in combination with BRAFV600E-inhibitors, is expected to deliver highly effective and tissue-restricted antimelanoma therapeutic responses.

Download · which file do I need?

Direct links to NCBI, 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.

All supplementary files ↗
3 · The original raw files

Whole study · RAW.tar

Everything the authors deposited as one archive (GSE70177_RAW.tar), including the raw array or instrument files. Can be large; the picker in step 2 takes just the samples you need.

What the files usually look like: For arrays the series matrix is normally the normalised expression table you want; the raw array files (CEL and similar) are in the RAW.tar.

Also filed as BioProject PRJNA287798. Searching any of these in the dataset finder brings you back here.
