    The effects of several structurally different inhibitors of AA metabolism in the human keratinocyte HaCaT cell line were examined. While eicosatetraynoic acid (ETYA), nordihydroguaiaretic acid (NDGA), esculetin and MK-886 reduced proliferation and induced apoptosis of HaCaT cells, the cyclooxygenase inhibitors indomethacin and piroxicam had no such effects. Esculetin induced redistribution of F-actin accompanied by increased cell adhesion and size. Our findings indicate that, in addition to their ability to inhibit cell proliferation and to induce apoptosis, lipoxygenase inhibitors and/or ETYA may also elicit other important physiological responses in HaCaT keratinocytes.
