Methods and techniques for in vitro subcellular localization of radiopharmaceuticals and radionuclides.

Nucl Med Biol 2021 Apr 22;98-99:18-29. Epub 2021 Apr 22.

Department of Imaging Chemistry and Biology, School of Biomedical Engineering and Imaging Sciences, King's College London, London SE1 7EH, United Kingdom. Electronic address:

In oncology, the holy grail of radiotherapy is specific radiation dose deposition in tumours with minimal healthy tissue toxicity. If used appropriately, injectable, systemic radionuclide therapies could meet these criteria, even for treatment of micrometastases and single circulating tumour cells. The clinical use of α and β particle-emitting molecular radionuclide therapies is rising, however clinical translation of Auger electron-emitting radionuclides is hampered by uncertainty around their exact subcellular localisation, which in turn affects the accuracy of dosimetry.

Nonsense-mediated RNA decay and its bipolar function in cancer.

Mol Cancer 2021 04 29;20(1):72. Epub 2021 Apr 29.

Departamento de Genética Humana, Instituto Nacional de Saúde Doutor Ricardo Jorge, 1649-016, Lisbon, Portugal.

Nonsense-mediated decay (NMD) was first described as a quality-control mechanism that targets and rapidly degrades aberrant mRNAs carrying premature termination codons (PTCs). However, it was found that NMD also degrades a significant number of normal transcripts, thus arising as a mechanism of gene expression regulation. Based on these important functions, NMD regulates several biological processes and is involved in the pathophysiology of a plethora of human genetic diseases, including cancer. Read More
