Research Abstract |
In order to clarify the role of HB-EGF in skin carcinogenesis, I produced the keratinocyte-specific HB-EGF deficient mouse and the keratinocyte-specific tetracycline-inducible HB-EGF transgenic mouse, and then chemical and ultraviolet induced carcinogenesis studies were performed. Papilloma and squamous carcinoma were detected at an early stage in HB-EGF transgenic mice compared to control. Conversely, there was little tumor generating in HB-EGF deficient mice. Taking together, overexpression of HB-EGF in vivo plays important roles in the pathogenesis of skin tumor formation.
