Brain Tumor Diagnostics and Therapeutics with Superparamagnetic Ferrite Nanoparticles.

abstract：:Overexpression of the chemokine-4 receptor (CXCR4) in brain tumors is associated with high cancer cell invasiveness. Recently, we reported the preclinical evaluation of 99mTc-CXCR4-L (cyclo-D-Tyr-D-[NMe]Orn[EDDA-99mTc-6-hydrazinylnicotinyl]-Arg-NaI-Gly) as a SPECT radioligand capable of specifically detecting the CXCR...
