Signal Transducers (STATs) 1 and 3 and Activator Protein 1 (AP-1) are transcription factors involved in the development of malignancy in colorectal carcinoma (CRC).
C-Jun has been proved as playing an important role in the pathogenesis of tumors, as a main component of Activator protein 1 and c-Jun gene polymorphisms are associated with colorectal cancer.
Combination analysis of activator protein-1 family members, Sp1 and an activator protein-2alpha-related factor binding to different regions of the urokinase receptor gene in resected colorectal cancers.
Here, we demonstrate the biological properties of AP-1 and its role in colorectal cancer, and discuss a possibility of an AP-1 inhibitor, an adenovirus dominant-negative mutant of c-Jun, as a therapeutic agent for gene therapy.
To investigate the role of AP-1 in colorectal cancer, we constructed an adenovirus-expressing TAM67, a dominant-negative mutant of c-Jun lacking the transactivation domain of wild c-Jun (DN-c-Jun), to inhibit endogenous AP-1.
