Abstract

Understanding the molecular basis of the metastatic spread of cancer and the underlying mechanisms is crucial for the development and appropriate clinical use of novel therapeutic agents directed at prevention of metastasis. Retinoids have been reported to inhibit cell proliferation, modulate cell differentiation, enhance apoptosis and to prevent the conversion of in situ cancer to locally invasive malignancy by suppressing the invasive process as well as by inhibiting angiogenesis. Fenretinide (4-HPR), a synthetic derivative of retinoic acid, is less toxic than natural retinoids and is active in the prevention and treatment of a variety of tumours in animal models. Its efficacy in cancer chemoprevention and therapy has been investigated in clinical trials. In order to evaluate the effects of 4-HPR on the late stages of tumour progression, chemically transformed BALB/c 3T3 cells, showing a fully malignant phenotype, were exposed to 4-HPR (0.25-10 microM; 72 hours pre-treatment) and ...
