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 JNKs are components of stress signaling pathways but also regulate morphogenesis and differentiation. Previously, we invoked a role for the JNKs in nerve growth factor (NGF)-stimulated PC12 cell neural differentiation (L. Marek et al., J. Cell. Physiol. 201:459-469, 2004; E. Zentrich et al., J. Biol. Chem. 277:4110-4118, 2002). Herein, the role for JNKs in neural differentiation and transcriptional regulation of the marker gene, NFLC, modeled in mouse embryonic stem (ES) cells was studied. NFLC-luciferase reporters revealed the requirement for NFLC promoter sequences encompassing base pairs -128 to -98 relative to the transcriptional start site as well as a proximal cyclic AMP response element-activating transcription factor binding site at -45 to -38 base pairs for transcriptional induction in NGF-treated PC12 cells and neurally differentiated ES cells. The findings reveal common promoter sequences that integrate conserved signal pathways in both PC12 cell and ES cell systems. To test the requirement for the JNK pathway in ES cell neurogenesis, ES cell lines bearing homozygous disruptions of the jnk1, jnk2, or jnk3 genes were derived and submitted to an embryoid body (EB) differentiation protocol. Neural differentiation was observed in wild-type, JNK2(-/-), and JNK3(-/-) cultures but not in JNK1(-/-) EBs. Rather, an outgrowth of cells with epithelial morphology and enhanced E-cadherin expression but low NFLC mRNA and protein was observed in JNK1(-/-) cultures. The expression of wnt-4 and wnt-6, identified inhibitors of ES cell neurogenesis, was significantly elevated in JNK1(-/-) cultures relative to wild-type, JNK2(-/-), and JNK3(-/-) cultures. Moreover, the Wnt antagonist, sFRP-2, partially rescued neural differentiation in JNK1(-/-) cultures. Thus, a genetic approach using JNK-deficient ES cells reveals a novel role for JNK1 involving repression of Wnt expression in neural differentiation modeled in murine ES cells.
