Shadow Enhancers as a Source of Evolutionary Novelty
Open accessAbstract
Some developmentally important genes can be regulated via two enhancers, one located nearby and the other, a "shadow" enhancer, 10 to 20 kilobases away.

Claims other papers make about this one
Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“Sub-additivity may also underlie some cases of functional enhancer redundancy, such as for Drosophila “shadow enhancers” that can “back up” important developmental enhancers and enable them to accumulate deleterious mutations [520–522].”
From Transcriptional enhancers and their communication with gene promoters (2021) · cites this paper as [520]
Experimental — accuracy not yet measuredIn the citing paper
“previous studies have identified shadow enhancers acting to mask the effects of perturbing individual enhancers (Hong et al., 2008)”
From A Genome-wide Framework for Mapping Gene Regulation via Cellular Genetic Screens (2019) · cites this paper as Hong et al., 2008

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
