4-Methyl-5-Pentylbenzene-1,3-Diol Regulates Chemotactic Cell Aggregation and Spore Maturation Via Different Mechanisms in Dictyostelium discoideum.
Article in Current microbiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
4-Methyl-5-pentylbenzene-1,3-diol (MPBD), a product of the polyketide synthase SteelyA, is a signaling molecule that regulates Dictyostelium discoideum development. During early development, MPBD controls chemotactic cell aggregation by regulating the expression of genes in the cAMP signaling pathway; however, during culmination at late development, it induces spore maturation. In the present study, we analyzed the effects of MPBD, its derivatives, and a putative MPBD-derived metabolite on developmental defects in the MPBD-less stlA null mutant. Using structure-activity relationship studies, it was observed that in MPBD, the functional groups that were essential for induction of spore maturation were different from those essential for induction of cell aggregation. Dictyoquinone, a putative MPBD metabolite rescued the aggregation defect in stlA null mutant in early development, but not the spore maturation defect at the later stage. Our data suggest that MPBD regulates chemotactic cell aggregation and spore maturation via different mechanisms.
