Creation of zebularine-resistant human cytidine deaminase mutants to enhance the chemoprotection of hematopoietic stem cells.

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
Human cytidine deaminase (hCDA) is a biomedically important enzyme able to inactivate cytidine nucleoside analogs such as the antileukemic agent cytosine arabinoside (AraC) and thereby limit antineoplastic efficacy. Potent inhibitors of hCDA have been developed, e.g. zebularine, that when administered in combination with AraC enhance antineoplastic activity. Tandem hematopoietic stem cell (HSC) transplantation and combination chemotherapy (zebularine and AraC) could exhibit robust antineoplastic potency, but AraC-based chemotherapy regimens lead to pronounced myelosuppression due to relatively low hCDA activity in HSCs, and this approach could exacerbate this effect. To circumvent the pronounced myelosuppression of zebularine and AraC combination therapy while maintaining antineoplastic potency, zebularine-resistant hCDA variants could be used to gene-modify HSCs prior to transplantation. To achieve this, our approach was to isolate hCDA variants through random mutagenesis in conjunction with selection for hCDA activity and resistance to zebularine in an Escherichia coli genetic complementation system. Here, we report the identification of nine novel variants from a pool of 1.6 × 10
