| 中文摘要 | molecular imaging of tumor biomarkers has a potential to accurately diagnose malignant tumors at its earliest stage. molecular mri of cancer-related fibronectin in tumor stroma was investigated with a targeted contrast agent (ca) in a mouse orthotopic pc-3 prostate cancer model. a clt1 (cgliiqknec) cyclic peptide targeted generation 2 nanoglobular gd-dota monoamide conjugate (clt1-targeted mri ca) was used for imaging fibronectin in tumor stroma. a conjugate of peptide karec was used as a control mri ca (non-targeted control). orthotopic pc-3 prostate tumors were established in the prostate of athymic nude male mice. tumor binding of clt1 peptide was examined by fluorescence imaging with fluorescently tagged peptide probes. mr imaging was performed with the mice bearing orthotopic pc-3 prostate tumors on a bruker biospec 7t animal mri scanner. clt1 showed specific binding in the prostate tumor without binding in normal tissues. the control peptide had little binding in both normal and tumor tissues. the clt1-targeted mri ca resulted in stronger contrast enhancement in the tumor tissue than the control mri ca. clt1-targeted mri ca is a promising molecular mri contrast agent for fibronectin in the tumor stroma. it has a potential for the diagnosis and assessing prognosis of malignant tumors with mri. |
