It has been found that 1,7-bis(4-hydroxyphenyl)-1,4-heptadien-3-one (EB30), a compound extracted from V. coloratum, can induce apoptosis of lung cancer cells through the PI3K/AKT and ERK1/2 pathways, so as to achieve a therapeutic effect on lung cancer. The gene discussed is MAPK3; the disease is lung cancer.
