Abadi et al. have examined the antiproliferative effects in HT-29 cells of clove essential oil nanoemulsions obtained using Tween 20, 80, and PEG [46]; the nanoemulsions were able to inhibit the proliferation of cancer cells in a time- and dose-dependent manner and induce apoptosis by upregulating caspase-3 activity. This evidence concerns the gene CASP3 and cancer.
