MDA-7 protein is regulated as tumors develop from benign moles to the full-blown skin cancer known as melanoma and secondly, how over-expression of the mda-7 gene will affect melanoma cancer cell growth.

...d to "multi-stage cacinogenesis," progressing from benign thickening of tissue, to pre-malignant papilloma formation, to carcinoma formation. In all three systems, Girardi and the team found that the absence of gamma-delta T cells resulted in a higher level of skin cancer formation.
