## Abstract An antigastric cancer monoclonal antibody, 3H11 and its Fab fragment, were labelled with aβemitter ^211^At using pβ(^211^At)βastatobenzoic acid (pAtBA) intermediate, in the yields of more than 30%. The astatinated antibodies were stable in vitro, and had specific immunoreactivity to hum

β¦ Synopsis
The cyclotron-produced radiohalogen, 211At, is eminently suitable as a possible therapeutic radionuclide. It decays by the emission of 6.8 MeV mean energy alpha-particles, which from a radiobiological viewpoint are of near optimal therapeutic LET. This paper reviews developments in the possible application of [211At]astato-labelled molecules as potential anti-tumour agents. Additionally, radio-dosimetric evidence is presented, and its implications for human cancer therapy are discussed.

## Abstract Overexpression of a heparinβbinding growth factor, midkine (MK), has been observed in many malignancies, making it an attractive therapeutic target. We used morpholino antisense oligomers to downregulate human MK expression in human prostate (PCβ3) and colon carcinoma (SW620) cells, and
