title: [The role of sonic hedgehog pathway in skin carcinogenesis].
abstract: Non melanoma skin cancers (NMSC) involving basal (BCC)--and squamosus cell carcinomas (SCC) and are the most frequent skin cancers in Caucasians. Ultraviolet radiation is the main environmental risk factor for NMSC development. The aim of this paper is to review the latest opinions concerning the role of sonic hedgehog pathway in non-melanoma skin cancers development. Experimental data indicate that sonic hedgehog pathway might be involved in skin carcinogenesis. Under physiological conditions sonic hedgehog pathway is responsible for normal embryogenesis, regeneration of damaged tissues and for regulation of cell proliferation. It was revealed that UVR caused inactivated mutation in PATCHED gene encoding Ptch1 protein. These events lead to deregulation of sonic hedgehog pathway trough activation of Smo protein and Gli transcriptional factors what stimulates cell proliferation and in consequence NMSC development. Literature data indicate that understanding of molecular background of skin cancers might be a reason for introduction of new therapeutic approaches including sonic hedgehog pathway inhibitors.
