RH-35 Cells

The H4-II-E (also referred to as RH-35) cell line is a derivative of the Reuber H-35 rat hepatoma. This cell line originated from a liver tumor induced in a male ACI rat by exposure to the chemical carcinogen N-2-fluorenyldiacetamide. When transplanted into ACI rats, H4-II-E cells form rapidly growing tumors with histological features characteristic of poorly differentiated hepatomas. They are particularly sensitive to the induction of aryl hydrocarbon hydroxylase (AHH) activity, making them a robust system for studying enzymatic responses to polycyclic aromatic hydrocarbons and dioxin-like compounds. H4-II-E cells also serve as a model for studying cellular responses to carcinogens and radiation, given their clonogenicity and the ability to assay long-term cell survival post-treatment. Their application extends to exploring the mechanisms of enzyme induction, xenobiotic metabolism, and liver-specific toxicology. These attributes make H4-II-E an invaluable tool in cancer research and toxicological screening.
