Anchorage-dependent expression of cyclin A in primary cells requires a negative DNA regulatory element and a functional Rb.

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
Many cells, when cultured in suspension, fail to express cyclin A, a regulatory component of cell cycle kinases cdc2 and cdk2 and as a consequence, do not enter S phase. However, many cell type-specific differences are disclosed between not only normal and transformed cells, but also between cell lines whose proliferation is strictly anchorage-dependent. These apparent discrepancies are seen in established cell lines most probably because of adaptative events that have occurred during cell culture. We have therefore used primary cells to understand how cyclin A transcription is controlled by cell anchorage properties. To this aim, we have used embryonic fibroblasts from either wild type, Rb(-/-) or p107(-/-)/p130(-/-) mice and tested the effect of an ectopic expression of Rb mutants. In the experiments reported here, we show that anchorage-dependent expression of cyclin A (i) is reflected by the in vivo occupancy of a negative DNA regulatory element previously shown to be instrumental in the down regulation of cyclin A transcription in quiescent cells (Cell Cycle Responsive Element: CCRE) (ii) requires a functional Rb but neither p107 nor p130 (iii) mutation of the CCRE abolishes both adhesion-dependent regulation and response to Rb.
