About Soy Isoflavones
Genistein reduced erythema and histologic inflammation induced by PUVA in mouse skin. Cells containing cleaved poly (adenosine disphosphate-ribose) polymerase and active caspase-3 generated by PUVA were completely inhibited by genistein. n addition, genistein inhibited UV-induced apoptotic changes, including caspase-3 and p21 activated kinase 2 activation in human epidermal carcinoma cells and phosphokinase C in human keratinocytes. Genistein inhibited UVB induced
c-Fos and c-Jun expression in mouse skin, apparently by tyrosine kinase nhibition.
Genistein has anti-inflammatory properties. In human epidermal cell cultures, it inhibited UVB-stimulated prostaglandin E2 synthesis and suppressed UVB-induced expression of cyclooxygenase-2 in keratinocytes. Finally, genistein has immunemodulating effects. Genistein inhibited UV-induced
immunosuppression in mice." Cutaneous photodamage, oxidative stress, and topical antioxidant protection (PDF) by Sheldon R. Pinnell, MD.
"In addition to its tyrosine kinase inhibitor effects, genistein is a potent AO. Genistein scavenged peroxyl radicals and protected against lipid peroxidation in vitro and in vivo. Genistein inhibited in vitro UV-induced DNA oxidation and cellular DNA oxidation induced by benzopyrene and UVA, psoralen plus UVA (PUVA) therapy, and phorbol ester stimulation. Genistein reduced hydrogen peroxide–generated DNA damage in human lymphocytes as determined by COMET assay.
