D009676 - Noxae > D002273 - Carcinogens Dibenz[a,h]anthracene (DBA) is a polycyclic aromatic hydrocarbon (PAH) of considerable tumorigenicity. Dibenz[a,h]anthracene results in DNA adduct formation leading to the activation of a DNA damage response. Dibenz[a,h]anthracene induces cell cycle arrest and apoptosis via both Tp53-dependent and Tp53-independent mechanisms[1][2].
