Background and Aims: Accurate endoscopic detection of premalignant lesions and early cancers in the colon is essential for cure, since prognosis is closely related to lesion size and stage. Although it has great clinical potential, autofluorescence endoscopy has limited tumor-to-normal tissue image contrast for detecting small preneoplastic lesions. We have developed a molecularly specific, near-infrared fluorescent monoclonal antibody (CC49) bioconjugate which targets tumor-associated glycoprotein 72 (TAG72), as a contrast agent to improve fluorescence-based endoscopy of colon cancer. Methods: The fluorescent anti-TAG72 conjugate was evaluated in vitro and in vivo in athymic nude mice bearing human colon adenocarcinoma (LS174T) subcutaneous tumors. Autofluorescence, a fluorescent but irrelevant antibody and the free fluorescent dye served as controls. Fluorescent agents were injected intravenously, and in vivo whole body fluorescence imaging was performed at various time points to determine pharmacokinetics, followed by ex vivo tissue analysis by confocal fluorescence microscopy and histology. Results: Fluorescence microscopy and histology confirmed specific LS174T cell membrane targeting of labeled CC49 in vitro and ex vivo. In vivo fluorescence imaging demonstrated significant tumor-to-normal tissue contrast enhancement with labeled-CC49 at three hours post injection, with maximum contrast after 48 h. Accumulation of tumor fluorescence demonstrated that modification of CC49 antibodies did not alter their specific tumor-localizing properties, and was antibody-dependent since controls did not produce detectable tumor fluorescence. Conclusions: These results show proof-of-principle that our near-infrared fluorescent-antibody probe targeting a tumor-associated mucin detects colonic tumors at the molecular level in real time, and offer a basis for future improvement of image contrast during clinical fluorescence endoscopy.

In order to determine a particular tumor cell via nanomaterials, we introduce the preparation of CD20 and CD5 coupled nanoprobes (denoted as CD20 and CD5 nanoprobes for convenience) and an application in identification of mantle cell lymphoma (MCL) from B-cell lymphoma. In this work, CD20 and CD5 nanoprobes were prepared by selectively oxidizing the carbon-carbon double bonds of oleate ligands on the surfaces of NaYF4:Yb3+,Tm3+ and NaYF4:Yb3+,Er3+ nanoparticles and, respectively, coupling carboxyl groups on the particles’ surfaces with CD20 and CD5 monoclonal antibodies through EDC/NHS crosslinking agents. After in situ hybridized Jeko-1 cells and Raji cells as a reference with CD20 and CD5 nanoprobes, in vitro double-color upconversion fluorescence imaging of Jeko-1 cells was demonstrated through visualization of blue and green fluorescence under a 980 nm laser excitation. Moreover, in vivo upconversion fluorescence imaging of the transplanted cancer model was also measured. These experimental results indicate that Jeko-1 cells have been specifically labeled by CD20 and CD5 nanoprobes. It is therefore concluded that CD20 and CD5 nanoprobes could be used to specially differentiate mantle cell lymphoma (MCL) from B-cell lymphoma.
