Welcome to OncoDB!
OncoDB is an online database resource for researchers to explore abnormal patterns in gene expression as well as viral infection that are correlated to clinical features in cancer. Specifically, OncoDB integrated RNA-seq, DNA methylation, and related clinical data from over 10,000 cancer patients in the TCGA study as well as from normal tissues in the GTEx study. Another unique aspect of OncoDB is its focus on oncoviruses. By mining TCGA RNA-seq data, we have identified six major oncoviruses across cancer types and further characterized the impact of viral infection on host gene expression and clinical outcomes. All the analysis results are integratively presented in OncoDB with a flexible interface to search for data related to RNA expression, DNA methylation, viral infection, and clinical features of the cancer patients.
