| Research Abstract |
Tumor hypoxic microenvironment is potentially an excellent marker for malignant tumors and in vivo imaging of intratumoral hypoxia is significant for cancer treatment.To construct the novel activatable protein probe, whose signals can be monitored only in hypoxic conditions, H-type dimer formation of fluorescent dyes was designed within the pVHL molecule to detect the structural change of pVHL. As the results, fluorescent signal of probe in native state is very low, while it was dramatically increased in denatured state, suggesting that signal intensity of the probe can be changed depending on its structure. This probe would be useful for the detection of intratumoral hypoxia.
