Background: Flavonoids are widely proposed as very interesting compounds with possible chemopreventive and therapeutic capacities.

Methods & Results: In this study, we showed that in vitro treatment with the flavonoid Luteolin induced caspase-dependent cell death in a model of human cutaneous squamous cell carcinoma (SCC) derived cells, representing a matched pair of primary tumor and its metastasis. Notably, no cytotoxic effects were observed in normal human keratinocytes when treated with similar doses of Luteolin.

Cutaneous squamous cell carcinoma (cSCC) is one of the most common cancers in the Caucasian population. Although early stages of skin cancer have a high curability and excellent prognosis, advanced cSCC shows resistance to chemotherapy, including cisplatin. The PI3-K/AKT pathway is known to have a role in both skin cancer development and resistance to therapeutic drugs.

Adequate protection of skin against the carcinogenic effects of UVB irradiation is essential. Flavonoids may have a conspicuous role in cancer prevention because of their antioxidant, anti-inflammatory, and growth-inhibitory effects. Therefore, we tested the effects of the flavone luteolin (LUT) on selected parameters of the sunburn response in normal human keratinocytes, exposed to physiological doses of UVB.

Adequate photoprotection is essential to control UV-related disorders, including sunburn, photoaging and photocarcinogenisis. Sun avoidance, protection of skin with clothing, and sunscreens are presently the best way of photoprotection, assuming that they are used properly. However, new strategies, which are based on or make use of the endogenous protective response to UV light, may further improve currently used photoprotective means.
