Caspase-dependent apoptosis by ectopic expression of E2F-4.
Article in Oncogene, 2000. 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
E2F is a family of transcription factors which regulates cell cycle and apoptosis of mammalian cells. E2F-1-3 localize in the nucleus, and preferentially bind pRb, while E2F-4 and 5 have no nuclear localization signal and preferentially bind p107/p130. E2F-6 suppresses the transcriptional activity of other E2F proteins. DP-1 and 2 are heterodimeric partners of each E2F protein. Using tetracycline-responsive promoters, here we compared the effects of ectopic expression of E2F-1, DP-1 and E2F-4 on cell cycle progression and apoptosis in Chinese hamster cell lines. We found that E2F-4, as well as DP-1 and E2F-1, induced growth arrest and caspase-dependent apoptosis. E2F-4 did not have a marked effect on cell cycle progression, while E2F-1 induced DNA synthesis of resting cells and DP-1 arrested cells in G1. Ectopic expression of E2F-4 did not activate E2F-dependent transcription. Our results suggest that expression of E2F-4 at elevated levels induces growth arrest and apoptosis of mammalian cells through a mechanism distinct from E2F-1 and DP-1.
