Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide and shows a propensity to metastasize and infiltrate adjacent and more distant tissues. HCC is associated with multiple risk factors, including hepatitis B virus (HBV) infection, which is especially prevalent in China. Here, we used exome sequencing to identify somatic mutations in ten HBV-positive individuals with HCC with portal vein tumor thromboses (PVTTs), intrahepatic metastases. Both C:G>A:T and T:A>A:T transversions were frequently found among the 331 non-silent mutations. Notably, ARID1A, which encodes a component of the SWI/SNF chromatin remodeling complex, was mutated in 14 of 110 (13%) HBV-associated HCC specimens. We used RNA interference to assess the roles of 91 of the confirmed mutated genes in cellular survival. The results suggest that seven of these genes, including VCAM1 and CDK14, may confer growth and infiltration capacity to HCC cells. This study provides a view of the landscape of somatic mutations that may be implicated in advanced HCC.

Table Information

Hide

The table currently shows only high value (numeric) copy number data. Copy number segments are excluded if the total copy number and minor allele values are unknown.

Click here to include all copy number data. For more detailed information about copy number data and gain/loss definitions click here.

Sample Gene Expression Expr Level (Z-Score)

Over Expressed; Z-Score > 2.0

Under Expressed; Z-Score < -2.0

Normal; Z-Score within the range -2.0 to 2.0

CN Type Minor Allele Copy Number CN Segment Posn. Average Ploidy

1. N/A represents cases where the average ploidy value is not available( mostly ICGC samples). For some TCGA samples where the minor allele information is not available the average ploidy value could not be calculated.

2. For TCGA samples, the ASCAT algorithm was used to calculate the average ploidy.

3. For CGP samples, the PICNIC algorithm was used to calculate the average ploidy.

CNV
This tab shows a summary table with counts (number of samples) for CNV gain/loss and under/over expression for all genes. [more details]

The results shown in this table are derived from all copy number data. This includes non-numeric data with descriptive definitions of gain/loss.
