Arsenic is a well-documented carcinogen of human urothelial carcinoma (UC) with incompletely understood mechanisms. This study aimed to compare the genome-wide DNA methylation profiles of arsenic-induced UC (AsUC) and non-arsenic-induced UC (Non-AsUC), and to assess associations between site-specific methylation levels
