Title: Identification of driver genes and target drugs-related genes in liver cancer based on targeted next generation sequencing
Author: Yunlong Cui, Liwei Sun, Hailong Wang, Zhenzhen Zhang, Hongxia Dai, Pengfei Liu

Abstract: The purpose of this study was to identify gene mutations, high frequency mutations, and driver genes in liver cancer, and the marketed approved drugs of these genes, to provide evidence for targeted treatment of liver cancer since it is one of the most common cancers worldwide. 34 patients with liver cancer were included, and their blood samples were collected. The pathway enrichment analysis of the mutation gene was carried out through the KEGG database, and the genes with marketed approved drugs were screened according to the Pharmalaxy database. A total of 6612 mutations in 1241 genes were identified in 34 patients, in which 22 genes mutated in at least 40% of the samples and were thought to be high frequency mutation genes. All the mutations were analyzed using the MutSigCV software, and 30 genes with q < 0.1 and P < 0.05 were selected out as driver genes. Among them, LRP1B, MYC, NF1, and KEAP1 were coincident with high frequency mutation genes, which were considered key driver genes. Afterward, 181 genes with P < 0.05 in MutSigCV software were analyzed for pathway enrichment. These genes were mainly enriched in four pathways, including MAPK mTOR, p53/cell cycle, and JAK-STAT pathways. Finally, there were 15 genes four pathways that had marketed approved target drugs.
To conclude, LRP1B, MYC, NF1, and KEAP1 were the candidate key driver genes for liver cancer, which might provide new insights for targeted therapy of liver cancer.
