The anti-tumor activity of Eucalyptol has been associated with the induction of cell apoptosis through Poly(ADP-ribose) polymerase (PARP) cleavage and the activation of caspase-3 [56] as well as inhibition of colorectal tumor cell viability through suppression of NF-κBp65/JAK and Bcl-2/Caspase signaling pathways [89]. The gene discussed is BCL2; the disease is colorectal neoplasm.
