Bioluminescent-based imaging and quantification of glucose uptake in vivo

Riccardo Sinisi, Elena Goun, Pavlo Khodakivskyi, Arkadiy Bazhin, Aleksey Yevtodiyenko, Tamara Maric, Georgy Mikhaylov

Glucose is a major source of energy for most living organisms, and its aberrant uptake is linked to many pathological conditions. However, our understanding of disease-associated glucose flux is limited owing to the lack of robust tools. To date, positron- ...

In vivo characterization of brain metabolism by 1 H MRS, 13 C MRS and 18 FDG PET reveals significant glucose oxidation of invasively growing glioma cells

Rolf Gruetter, Marta Lai, Cristina Ramona Cudalbu, Bernard Lanz, Carole Poitry-Yamate

Glioblastoma are notorious for their highly invasive growth, diffusely infiltrating adjacent brain structures that precludes complete resection, and is a major obstacle for cure. To characterize this "invisible" tumor part, we designed a high resolution mu ...
