1 · What the graph read from it

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.

2 · The registry

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

We have identified a novel mechanism of cross-talk between cell signaling and metabolic pathways, whereby the signaling kinase p21-activated kinase 1 (Pak1) binds to, phosphorylates and enhances the enzymatic activity of phosphoglucomutase 1 (PGM), an important regulatory enzyme in cellular glucose utilization and energy homeostasis. Pak1 and PGM were colocalized in model cell systems and showed functional interactions in a physiological setting. Strong direct interaction of PGM with Pak1 but not Pak2, Pak3, or Pak4 was observed. PGM binding was within 75-149 amino acids (aa) of Pak1, while Pak1 binding to PGM was in the N-terminal 96 aa. Pak1-mediated phosphorylation of PGM selectively on threonine 466 significantly increased PGM enzymatic activity and could be blocked by transfection with a dominant-negative Pak1 expression vector and by Pak1-specific small inhibitory RNA. Stable transfection of PGM into PGM-deficient K562 leukemia cells further demonstrated the role of Pak1 in regulating PGM activity. The results presented here provide new evidence that the cell signaling kinase Pak1 is a novel regulator of glucose metabolism through its phosphorylation and regulation of PGM activity. These findings suggest a new mechanism whereby growth factor signaling may coordinately integrate metabolic regulation with established signaling functions of cell cycle regulation and cell growth.
