Development of a retroviral vector for inducible expression of transforming growth factor beta 1.

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
A retroviral vector system for the expression of exogenous genes under the control of an inducible promoter was developed. By utilizing this system, the cDNA for human transforming growth factor beta 1 (TGF-beta 1) was inserted into a retroviral vector under the control of an internal mouse metallothionein promoter and introduced via infection into normal rat kidney fibroblasts (NRK-49F) and epithelial cells (NRK-52E), Chinese hamster ovary cells (CHO), and the human monocytic cell line U937. Control of TGF-beta 1 expression, achieved by Cd2+ induction of vector-encoded TGF-beta 1 mRNA, was cell line specific and resulted in a concomitant increase in neutralizable TGF-beta 1 production by the cells. Autocrine stimulation of vector-containing cells by vector-encoded TGF-beta 1 was detected by an increase in soft-agar colony formation of NRK-49F infectants compared with that of the control cells. In addition, the use of a second internal promoter in a retroviral vector of similar design allowed isolation of stable infectants from a cell line (CHO) in which the viral long terminal repeat does not function efficiently.
