Non-transcriptional Function of FOXO1/DAF-16 Contributes to Translesion DNA Synthesis.
Article in Molecular and cellular biology, 2016. 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
Forkhead box O (FOXO; DAF-16 in nematode) transcription factors activate a program of genes that control stress resistance, metabolism, and lifespan. Given the adverse impact of the stochastic DNA damage on organismal development and ageing, we examined the role of FOXO/DAF-16 in UV-induced DNA-damage response. Knockdown of FOXO1, but not FOXO3a, increases sensitivity to UV irradiation when exposed during S phase, suggesting a contribution of FOXO1 to translesion DNA synthesis (TLS), a replicative bypass of UV-induced DNA lesions. Actually, FOXO1 depletion results in a sustained activation of the ATR-Chk1 signaling and a reduction of PCNA monoubiquitination following UV irradiation. FOXO1 does not alter the expression of TLS-related genes but binds to the protein replication protein A (RPA1) that coats single-stranded DNA and acts as a scaffold for TLS. In Caenorhabditis elegans, daf-16 null mutants show UV-induced retardation in larval development and are rescued by overexpressing DAF-16 mutant lacking transactivation domain, but not substitution mutant unable to interact with RPA-1. Thus, our findings demonstrate that FOXO1/DAF-16 is a functional component in TLS independently of its transactivation activity.
