Re-targeted adenovirus vectors with dual specificity; binding specificities conferred by two different Affibody molecules in the fiber.
Article in Gene therapy, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Vectors based on Adenovirus type 5 (Ad5) are among the most common vectors in cancer gene therapy trials to date. However, for increased efficiency and safety, Ad5 should be de-targeted from its native receptors and re-targeted to a tumor antigen. We have described earlier an Ad5 vector genetically re-targeted to the tumor antigen HER2/neu by a dimeric version of the Affibody molecule ZH inserted in the HI-loop of the fiber knob of a coxsackie and adenovirus receptor-binding ablated fiber. This virus showed almost wild-type growth characteristics and infected cells through HER2/neu. Here we generate vectors with double specificity by incorporating two different Affibody molecules, ZH (HER2/neu-binding) and ZT (Taq polymerase-binding), at different positions relative to one another in the HI-loop. Receptor-binding studies together with viral production and gene transfer assays showed that the recombinant fiber with ZT in the first position and ZH in the second position (ZTZH) bound to both its targets, whereas surprisingly, the fiber with ZHZT was devoid of binding to HER2/neu. Hence, it is possible to construct a recombinant adenovirus with dual specificity after evaluating the best position for each ligand in the fiber knob.
