Pan-cancer analysis of TP53 mutations and their association with liver cancer and aristolochic acids

Abstract

Liver cancer is a major global health concern, as its incidence continues to rise in numerous countries, making it a leading cause of cancer-related deaths. The TP53 gene, which encodes the p53 tumor suppressor protein, plays a crucial role in regulating cell growth and division. Mutations in TP53 have been implicated in increased risk for liver cancer development. In this study, we aim to conduct a pan-cancer analysis to further investigate the potential role of TP53 mutations in various cancer types and their relationship with liver cancer. Additionally, we will explore the interplay between TP53 gene mutations, liver cancer, and exposure to Aristolochic acids (AAs). To achieve these goals, we will utilize data from The Cancer Genome Atlas (TCGA) project and the Gene Expression Omnibus (GEO) databases, enabling a comprehensive analysis of TP53 in the context of multiple cancer types.
