Since cholangiocarcinoma represents a tumor type that develops under inflammatory conditions and in settings of oxidative stress, the authors investigated the role of H19 in cholangiocarcinoma cell lines and observed tumor-promoting and pro-inflammatory actions of H192, In contrast, H19 was found to have tumor-suppressing abilities in colorectal cancer, another inflammation-associated tumor entity 3, and the role of H19 in inflammation is conflicting 4, 5. The gene discussed is H19; the disease is colorectal cancer.
