Calcineurin inhibitors are the mainstay of immunosuppressive treatment for organ transplant recipients. However, treatment with these drugs commonly leads to squamous cell carcinoma (SCC) of the skin. It is shown here that an intact calcineurin/NFAT signalling pathway is important for suppressing SCC development. Inhibition of this pathway leads to increased expression of the ATF3 protein, which has a key role in tumorigenesis.
