Antithymidylate resistance enables transgene selection and cell survival for T cells in the presence of 5-fluorouracil and antifolates.
Article in Gene therapy, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Antithymidylates (AThy) constitute a class of drugs used in the treatment of cancers such as lung, colon, breast and pancreas. These drugs inhibit DNA synthesis by targeting the enzymes dihydrofolate reductase (DHFR) and/or thymidylate synthase (TYMS). AThys effectively inhibit cancer cells, and also inhibit T cells, preventing anticancer immunity, which might otherwise develop from AThy-induced cancer destruction. We establish that T cells expressing mutant DHFR--DHFR L22F, F31S (DHFR(FS))--and/or mutant TYMS--TYMS T51S, G52S (TYMS(SS))-effectively survive in toxic concentrations of AThys methotrexate, pemetrexed and 5-fluorouracil. Furthermore, we show that DHFR(FS) permitted rapid selection of an inducible suicide transgene in T cells. These findings demonstrate that AThy resistances prevent AThy cytotoxicity to T cells while permitting selection of important transgenes. This technological development could enhance in vitro and in vivo survival and selection of T-cell therapeutics being designed for a broad range of cancers.
