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

The mitogen-activated protein kinase (MAPK) pathway integrates growth factor signaling through extracellular signal-regulated kinase (ERK) to control cell proliferation. To study ERK dynamics, many researchers use an ERK activity kinase translocation reporter (KTR). Our study reveals that this ERK KTR also partially senses cyclin-dependent kinase 2 (CDK2) activity, making it appear as if ERK activity rises as cells progress through the cell cycle. Through single-cell time-lapse imaging, we identified a residual ERK KTR signal that was eliminated by selective CDK2 inhibitors, indicating crosstalk from CDK2 onto the ERK KTR. By contrast, EKAREN5, a FRET-based ERK sensor, showed no CDK2 crosstalk. A related p38 KTR is also partly affected by CDK2 activity. To address this, we developed linear and non-linear computational correction methods that subtract CDK2 signal from the ERK and p38 KTRs. These findings will allow for more accurate quantification of MAPK activities, especially for studies of actively cycling cells.
