Abstract：
:Tissue characterisation by fluorescence imaging, using exogenous fluorophores, is a promising method for cancer detection. Histochemical alterations in the composition of mucins, when neoplastic transformations occur, could be exploited to derive more selective fluoroprobes indicative of early malignant transformation. The aim of this work was to develop and examine tumour selective fluoroprobes for colon cancer diagnosis, as well as to determine the morphological components where selective dye accumulation has occurred. Two novel fluoroprobes: rhodamine B-L-leucine amide and rhodamine B-phenylboronic acid were synthesised and examined together with Mayer's mucicarmine, alexa 350-wheat germ agglutinin (WGA) and tetramethyl rhodamine-concanavalin A (ConA). Fluorescence microscopy studies were performed with deparaffinised human colon sections, using an epifluorescence microscope equipped with a colour CCD camera. The intense accumulation of the novel fluoroprobes was localised in the amorphous material in the lumen of neoplastic crypts. To gain insight into the localisation patterns, mucicarmine, alexa 350-WGA and tetramethyl rhodamine-ConA were used. Alexa 350-WGA reacted primarily with mucin secreted in the malignant crypt lumen suggesting that this material is rich in sialic acid and N-acetylglucosaminyl residues. These derivatives clearly and consistently distinguished non-neoplastic from neoplastic human colon tissue sections. The intense accumulation at the altered mucins indicates that they could be used as fluoroprobes of biochemical alterations for carcinoma detection.
