New scientific paper published on the mechanism of action of Polyphenon E, a defined extract from green tea leaves, in preliminary stages of skin cancer

DERMAGO GmbH today announced the publication of an article by the research group of PD Dr. J. Eberle from Charité-Universitätsmedizin Berlin, Germany.

The article entitled “Inhibition of Cell Proliferation and Cell Viability by Sinecatechins in Cutaneous SCC Cells Is Related to an Imbalance of ROS and Loss of Mitochondrial Membrane Potential” was released in the peer-reviewed journal Antioxidants¹

Within the framework of the study, the authors led by PD Dr. Eberle and Prof. Dr. Stockfleth were able to demonstrate that Polyphenon® E induces a concentration-dependent inhibition of cell proliferation as well as a reduction of cell vitality in four different squamous cell carcinoma cell lines (SCL-I, SCL-II, SCC-12 and SCC-13). These modifications correlate with changes in mitochondria as well as with an imbalance of cellular reactive oxygen compounds. The new findings support the previously known comprehensive mechanism of action² of Polyphenon® E. On the basis of the results, the authors conclude a possible efficacy of Polyphenon® E in the indication actinic keratosis (AK).

Preliminary squamous cell carcinomas such as actinic keratosis (AK) have been among the most common skin diseases treated by dermatologists. Furthermore, a significant increase in actinic keratoses has been observed in the last decade. Apart from etiological factors such as chronic UV exposure, this can be attributed to demographic change with a higher proportion of older people in the population. An estimated 1.7 million people in Germany are currently undergoing dermatological treatment for AK. Actually, the number of patients suffering from AK is much higher and is expected to increase in the next years in line with the population structure.
