Retroviral transfer and expression of human MDR-1 in a murine haemopoietic stem cell line does not alter factor dependence, growth or differentiation characteristics.

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
In view of the recent report of a myeloproliferative syndrome in mice that had received an MDR-1-transduced haemopoietic graft, we have investigated the potential effects of MDR-1 expression on primitive haemopoietic cell growth and differentiation. Retroviral gene transfer was used to achieve exogenous expression of either MDR-1 or truncated nerve growth factor receptor (tNGFR) in the multipotent murine haemopoietic progenitor cell line, FDCP-mix. Following gene transfer, clonal lines were derived and FACS analysis confirmed appropriate expression of each transgene. MDR-1 (but not tNGFR) expression was associated with verapamil-sensitive rhodamine efflux and resistance to killing by etoposide. When growth factor responsiveness, proliferative capacity and differentiation capacity were examined, MDR-1 expressing FDCP-mix cells exhibited a normal phenotype and mimicked the response of tNGFR-expressing or untransduced FDCP-mix cells. Thus, in the model system we have used, MDR-1 does not perturb haemopoietic cell growth and development and our data do not support a myeloproliferative role for MDR-1.
