Abstract: Abstract Extracellular signal-regulated kinases (ERK) regulate cellular functions in response to a variety of external signals. However, the specific functions of individual ERK isoforms are largely unknown. Hence, we have investigated the specific function of ERK1 in skin homeostasis and tumorigenesis in ERK1 knockout mice. They spontaneously develop cutaneous lesions and hyperkeratosis with epidermis thickness. Skin hyperproliferation and inflammation induced by application of 12-O-tetradecanoylphorbol-13-acetate (TPA) is strongly reduced in ...
