Overexpression of Receptor Tyrosine Kinase EphB4 Triggers Tumor Growth and Hypoxia in A375 Melanoma Xenografts: Insights from Multitracer Small Animal Imaging Experiments

Molecules, 2018
Experimental evidence has associated receptor tyrosine kinase EphB4 with tumor angiogenesis also in malignant melanoma. Considering the limited in vivo data available, we have conducted a systematic multitracer and multimodal imaging investigation in ...

Stability of Silver Nanoparticles as Imaging Materials [PDF]

Journal of Pure and Applied Chemistry Research, 2016
Determining the stability of silver nanoparticles is a very important process. It was associated with unwanted metal charge and materials properties. Therefore, we studied to synthesis and stability of silver nanoparticles (AgNPs).

Preclinical evaluation of an 18F-labeled N ε-acryloyllysine piperazide for covalent targeting of transglutaminase 2

EJNMMI Radiopharmacy and Chemistry
Background Transglutaminase 2 (TGase 2) is a multifunctional protein and has a prominent role in various (patho)physiological processes. In particular, its transamidase activity, which is rather latent under physiological conditions, gains importance in ...

The Role of Transglutaminase 2 in the Radioresistance of Melanoma Cells

Cells, 2022
Transglutaminase 2 (TG2) is a protein expressed in many tissues that exerts numerous, sometimes contradictory, intra- and extracellular functions, under both physiological and pathophysiological conditions.

Cyclotron-Based Production of ⁶⁷Cu for Radionuclide Theranostics via the ⁷⁰Zn(p,α)⁶⁷Cu Reaction

Pharmaceuticals, 2023
Theranostic matched pairs of radionuclides have aroused interest during the last couple of years, and in that sense, copper is one element that has a lot to offer, and although 61Cu and 64Cu are slowly being established as diagnostic radionuclides for ...

Enhanced contrast in FAP-targeting PET imaging with 61Cu-labeled FAP inhibitors: development and preclinical evaluation of novel [61Cu]Cu-Kalios PET radioligands

EJNMMI Radiopharmacy and Chemistry
Background Fibroblast activation protein (FAP)-targeting radioligands have gained attention for the ability to image multiple tumor types. Current FAP-targeting radioligands are labeled with 68Ga and 18F, but their short half-lives limit distribution ...

Production of the PET radionuclide 61Cu via the 62Ni(p,2n)61Cu nuclear reaction

EJNMMI Radiopharmacy and Chemistry
Background There are only a handful of true theranostic matched pairs, and in particular the theranostic radiocopper trio 61Cu, 64Cu and 67Cu, for diagnosis and therapy respectively, is a very attractive candidate. In fact, the alternative of two imaging
