result sql = The imaging of tumor cells and tumor tissue samples is very important for cancer detection and therapy. We have taken advantages of fluorescent silica nanoparticles (FSiNPs) coupled with a molecular recognition element that allows for effective in vitro and ex vivo imaging of tumor cells and tissues. In this study, we report on the targeting and imaging of MDA-MB-231 human breast cancer cells using arginine-glycine-aspartic acid (RGD) peptide-labeled FSiNPs. When linked with RGD peptide using the cyanogen bromide (CNBr) method, the FSiNPs exhibited high target binding to alphavbeta3 integrin receptor (ABIR)-positive MDA-MB-231 breast cancer cells in vitro. Further study regarding the ex vivo imaging of tumor tissue samples was also carried out by intravenously injecting RGD peptide-labeled FSiNPs into athymic nude mice bearing the MDA-MB-231 tumors. Tissue images demonstrated that the high integrin alphavbeta3 expression level of the MDA-MB-231 tumors was clearly visible due to the special targeting effects of the RGD peptide-labeled FSiNPs, and the tumor fluorescence reached maximum intensity at 1 h postinjection. Our results break new ground for using FSiNPs to optically image tumors, and may also broaden the applications of silica nanoparticles in biomedicine.

result sql = The imaging of tumor cells and tumor tissue samples is very important for cancer detection and therapy. We have taken advantages of fluorescent silica nanoparticles (FSiNPs) coupled with a molecular recognition element that allows for effective in vitro and ex vivo imaging of tumor cells and tissues. In this study, we report on the targeting and imaging of MDA-MB-231 human breast cancer cells using arginine-glycine-aspartic acid (RGD) peptide-labeled FSiNPs. When linked with RGD peptide using the cyanogen bromide (CNBr) method, the FSiNPs exhibited high target binding to alphavbeta3 integrin receptor (ABIR)-positive MDA-MB-231 breast cancer cells in vitro. Further study regarding the ex vivo imaging of tumor tissue samples was also carried out by intravenously injecting RGD peptide-labeled FSiNPs into athymic nude mice bearing the MDA-MB-231 tumors. Tissue images demonstrated that the high integrin alphavbeta3 expression level of the MDA-MB-231 tumors was clearly visible due to the special targeting effects of the RGD peptide-labeled FSiNPs, and the tumor fluorescence reached maximum intensity at 1 h postinjection. Our results break new ground for using FSiNPs to optically image tumors, and may also broaden the applications of silica nanoparticles in biomedicine.

The imaging of tumor cells and tumor tissue samples is very important for cancer detection and therapy. We have taken advantages of fluorescent silica nanoparticles (FSiNPs) coupled with a molecular recognition element that allows for effective in vitro and ex vivo imaging of tumor cells and tissues. In this study, we report on the targeting and imaging of MDA-MB-231 human breast cancer cells using arginine-glycine-aspartic acid (RGD) peptide-labeled FSiNPs. When linked with RGD peptide using the cyanogen bromide (CNBr) method, the FSiNPs exhibited high target binding to alphavbeta3 integrin receptor (ABIR)-positive MDA-MB-231 breast cancer cells in vitro. Further study regarding the ex vivo imaging of tumor tissue samples was also carried out by intravenously injecting RGD peptide-labeled FSiNPs into athymic nude mice bearing the MDA-MB-231 tumors. Tissue images demonstrated that the high integrin alphavbeta3 expression level of the MDA-MB-231 tumors was clearly visible due to the special targeting effects of the RGD peptide-labeled FSiNPs, and the tumor fluorescence reached maximum intensity at 1 h postinjection. Our results break new ground for using FSiNPs to optically image tumors, and may also broaden the applications of silica nanoparticles in biomedicine.
