Chemo-manipulation of tumor blood vessels by a metal-based anticancer complex enhances antitumor therapy

Paul Joseph Dyson, Hubert van den Bergh, Tina Riedel

Human pleural mesothelioma is an incurable and chemoresistant cancer. Using a nude mouse xenograft model of human pleural mesothelioma, we show that RAPTA-T, a compound undergoing preclinical evaluation, enhances tumor vascular function by decreasing blood ...

Hyperpolarized 6Li as a probe for hemoglobin oxygenation level

Rolf Gruetter, Arnaud Comment, Mor-Miri Mishkovsky, Ruud van Heeswijk, Riccardo Balzan

Hyperpolarization by dissolution dynamic nuclear polarization (DNP) is a versatile technique to dramatically enhance the nuclear magnetic resonance (NMR) signal intensity of insensitive long-T1 nuclear spins such as 6 Li. The 6 Li longitudinal relaxation o ...

Angiostatic treatment prior to chemo- or photodynamic therapy improves anti-tumor efficacy

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Andrea Brett Gasser, Débora Bonvin

Tumor vasculature is known to be poorly organized leading to increased leakage of molecules to the extravascular space. This process can potentially increase interstitial fluid pressure impairing intra-tumoral blood flow and oxygen supply, and can affect d ...

Low-dose angiostatic tyrosine kinase inhibitors improve photodynamic therapy for cancer: lack of vascular normalization

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Andrea Brett Gasser, Débora Bonvin

Photodynamic therapy (PDT) is an effective clinical treatment for a number of different cancers. PDT can induce hypoxia and inflammation, pro-angiogenic side effects, which may counteract its angio-occlusive mechanism. The combination of PDT with anti-angi ...
