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

Understanding and controlling the mechanism by which stem cells balance self-renewal versus differentiation is of great importance for stem cell therapeutics. Klf4 promotes the self-renewal of embryonic stem cells, but the precise mechanism regulating this role of Klf4 is unclear. We found that ERK1 or ERK2 binds the activation domain of Klf4 and directly phosphorylates Klf4 at Ser123. This phosphorylation suppresses Klf4 activity, inducing embryonic stem cell differentiation. Conversely, inhibition of Klf4 phosphorylation enhances Klf4 activity and suppresses embryonic stem cell differentiation. Notably, phosphorylation of Klf4 by ERKs causes recruitment and binding of the F-box proteins βTrCP1 or βTrCP2 (components of an ubiquitin E3 ligase) to the Klf4 N-terminal domain, which results in Klf4 ubiquitination and degradation. Overall, our data provide a molecular basis for the role of ERK1 and ERK2 in regulating Klf4-mediated mouse embryonic stem cell self-renewal.
