Figure 2From: Increased expression of AP2 and Sp1 transcription factors in human thyroid tumors: a role in NIS expression regulation?Western blot analysis of nuclear extracts from normal and cancer tissues, using monoclonal anti-AP2 and anti-Sp1 antibodies. The cancerous tissues displayed higher levels of both transcription factors, compared with normal thyroid tissues. A representative of three separated assays is shown. N = normal thyroid tissue; T = tumoral thyroid tissue.Back to article page
