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

Neural stem cells (NSC) undergo apoptotic cell death during development of nervous system and in adult. However, little is known about the biochemical regulation of neuroprotection by neurotrophin in these cells. In this report, we demonstrate that Staurosporine (STS) and Etoposide (ETS) induced apoptotic cell death of NSC by a mechanism requiring Caspase 3 activation, poly (ADP-ribose) polymerase and Lamin A/C cleavage. Although C17.2 cells revealed higher mRNA level of p75 neurotrophin receptor (p75(NTR)) compared with TrkA or TrkB receptor, neuroprotective effect of both nerve growth factor (NGF) and brain-derived growth factor (BDNF) mediated through the activation of tropomyosin receptor kinase (Trk) receptors. Moreover, both NGF and BDNF induced the activation of the phosphatidylinositide 3 kinase (PI3K)/Akt and the mitogen-activated protein kinase (MAPK) pathway. Inhibition of Trk receptor by K252a reduced PARP cleavage as well as cell viability, whereas inhibition of p75(NTR) did not affect the effect of neurotrophin on neurotoxic insults. Thus our studies indicate that the protective effect of NGF and BDNF in NSC against apoptotic stimuli is mediated by the PI3K/Akt and MAPK signaling pathway via Trk receptors.
