Identification of Psk2, Skp1, and Tub4 as trans-acting factors for uORF-containing ROK1 mRNA in Saccharomyces cerevisiae.
Article in Journal of microbiology (Seoul, Korea), 2015. 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
Rok1, a DEAD-box RNA helicase, is involved in rRNA processing and the control of cell cycle progression in Saccharomyces cerevisiae. Rok1 protein expression is cell cycle-regulated, declining at G1/S and increasing at G2. The downregulation of Rok1 expression in G1/S phase is mediated by the inhibitory action of two upstream open reading frames (uORFs) in the ROK1 5'-untranslated region (5'UTR). We identified Psk2 (PAS kinase), Skp1 (kinetochore protein) and Tub4 (γ-tubulin protein) as ROK1 5'UTR-interacting proteins using yeast three-hybrid system. A deletion analysis of PSK2 or inactivation of temperature-sensitive alleles of SKP1 and TUB4 revealed that Rok1 protein synthesis is repressed by Psk2 and Skp1. This repression appeared to be mediated through the ROK1 uORF1. In contrast, Tub4 plays a positive role in regulating Rok1 protein synthesis and likely after the uORF1-mediated inhibitory regulation. These results suggest that 5'UTR-interacting proteins, identified using three hybrid screening, are important for uORF-mediated regulation of Rok1 protein expression.
