Honokiol antitumor effects have been experimentally tested in different types of cancer, including lung cancer, where it was shown to play an anti-metastatic role through the inhibition of pro-metastatic proteins, among which was β-catenin, known to synergize with YAP/TAZ and to be a target itself of YAP and TAZ [198,199,200]. This evidence concerns the gene YAP1 and cancer.
