[99mTc]Tc-duramycin, a potential molecular probe for early prediction of tumor response after chemotherapy

ObjectiveApoptosis plays a crucial role in many biological processes, especially in cancer. However, real-time monitoring of apoptosis is challenging. [99mTc]duramycin can selectively target an apoptosis biomarker: phosphatidylethanolamine (PE), which is normally located on the intracellular cell-membrane surface but redistributes onto the outer cell-membrane upon apoptosis. Therefore, 99mTc-duramycin is a potential probe for non-invasive detection of apoptosis in real-time. The aim of this study was to evaluate the value of [99mTc]duramycin for detecting early apoptotic response in tumors after chemotherapy, thus providing a tool for early prediction of curative effects in tumors.
