• Cancer: Keratinocytes were used in this study to demonstrate that dysregulated activation of type I interferon innate immunity is implicated in the molecular processes triggered by anti-EGFR drugs and leading to persistent skin inflammation. Carrie HS, Hong Y, Yunbo L, Jennifer SM, Sridevi B, Gaylene S, Judith AC and Thomas RS.  EGF receptor signaling blocks aryl hydrocarbon receptor-mediated transcription and cell differentiation in human epidermal keratinocytes.

• Human Papillomaviruses (HPV) mediated skin cancer response: An infection of the skin with human papillomaviruses (HPV) may result in benign tumors with limited growth, which tend to regress spontaneously and causes non-melanoma skin cancer development in epidermodysplasia verruciformis (EV) and immunosuppressed patients.  The present study utilized pooled keratinocytes cultured in KGM^TM-Gold Medium from several healthy donors. The data showed that betaPV may increase the number of stem cell-like cells present during early carcinogenesis and thus enable the persistence and accumulation of DNA damage necessary to generate malignant stem cells. Martin H, Adrian B, Cinzia B, Marisa G, John D, Alan S, Herbert P, Ian M and Baki A.
