Figure 1From: Assessing the clinical utility of measuring Insulin-like Growth Factor Binding Proteins in tissues and sera of melanoma patientsIGFBP-3 and -4 expressions in primary melanoma tissue were evaluated with IHC. (A) IGFBP-3 protein had low levels of expression in primary melanoma tissues, while (B) IGFBP-4 protein had high levels of expression in primary melanoma tissue.
