Project description:SNP array data from 125 hepatocellular carcinomas were used to detect recurrent copy number alterations. 99 hepatocellular carcinomas and 86 matched normal samples were analyzed with Illumina HumanCNV370-Duo v1.0 chips. 26 hepatocellular carcinomas and 26 matched normal samples were analyzed with Illumina HumanOmniExpress BeadChip.
Project description:High frequency of loss of heterozygosity (LOH) at locus D4S2964 was found in hepatocellular carcinoma (HCC) by our previous studies and others’. The present study was designed to explore genes around the locus affected by LOH and their clinical implications. 440 SNPs located at 49 genes around D4S2964 were selected from NCBI website for the SNPs microarray fabrication. LOH of these SNPs markers in 112 cases of HCC tissues and paired adjacent liver tissues were investigated by the SNP microarray. A map of LOH of SNPs in genes around D4S2964 was constructed. 112 pairs of HCC tissues and corresponding non-tumor tissues was genotyped. LOH and its clinical implication was analyzed.
Project description:Genome-wide DNA methylation profiling was performed in paired samples of non-cancerous liver tissue and the corresponding cancerous tissue obtained from patients with hepatitis virus-related hepatocellular carcinomas using the Illumina Infinium HumanMethylation450 Beadchip.
