Summary (written by the submitters)
Intrahepatic cholangiocarcinoma (ICC) is a lethal cancer arising from intrahepatic bile ducts in the liver. In the intraductal growth (IDG) type, also referred to as intraductal papillary neoplasm of the bile duct (IPNB), a rare subtype of ICC, cancer cells originating within the bile duct usually invade and infiltrate the nearby liver tissues, resulting in local invasion.

IPNB can serve as a good disease model to study the mechanism of local invasion, which is the earliest step of metastasis. Here, we aimed to identify the genes associated with local invasion by comparing the somatic mutations of the matched IPNB tissues with and without local invasion from a set of 11 patients using the Ion AmpliSeq Comprehensive Cancer Panel. Somatic mutation profiling analysis identified RNF213 as a potential candidate gene associated with local invasion in ICC patients. We established stable RNF213-knockdown and shControl cholangiocarcinoma (CCA) cell lines (HuCCT1, YSCCC, and KKU-100). Next, the expression profiling of the RNF213-knockdown and shContol CCA cell lines was analyzed by RNA sequencing.

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 GSE235891_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 PRJNA987989 and SRA study SRP446234. Searching any of these in the dataset finder brings you back here.
