Basal extracellular signal-regulated kinase activity modulates cell-cell and cell-matrix interactions.
Article in Molecular and cellular biology, 1998. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 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
Suppression of the basal extracellular signal-regulated kinase (ERK) activity in PC12 cells markedly altered their phenotype. Wild-type cells grew in a dissociated pattern adherent to the substrate. The stable expression of an ERK inhibitory mutant resulted in the formation of calcium-dependent aggregates which were less adherent to the substrate. Concomitantly, the cells reorganized their actin cytoskeleton and increased their expression of several adherens junction proteins, particularly cadherin. Metabolic labeling demonstrated an increased synthesis of cadherin and beta-catenin in these cells. Nontransfected PC12 cells and a ras-transformed MDCK cell line also formed aggregates and increased their expression of adherens junction proteins following treatment with the selective MEK inhibitor PD98059. A peptide containing the HAV cadherin recognition sequence attenuated the aggregation. These studies suggest that in PC12 and epithelial cells, ERKs are pivotally positioned to enhance substrate interactions when active or to release homotypic interactions when suppressed.
