Figure 4From: A moderate elevation of circulating levels of IGF-I does not alter ErbB2 induced mammary tumorigenesis Increased circulating IGF-I does not alter growth in ErbB2-induced mammary gland turmors. Graphs plotting individual tumor growth curves for ErbB2 (left) and bigenic (right) females. Statistical analysis revealed that increased circulating levels of IGF-I (right) had no significant (p = 0.23) affect on mammary tumor growth compared to ErbB2 only induced mammary tumors. N = 16 for ErbB2 group and 15 for TTR-IGF-I-ErbB2 bigenic group.Back to article page
