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

backgroundPituitary adenylate cyclase-activating polypeptide (PACAP) has beneficial effects in learning and memory. However, the mechanism by which PACAP improves cognitive impairment of vascular dementia (VaD) is not clear.

methodsWe established a VaD model by bilateral common carotid stenosis (BCAS) to investigate the molecular mechanism of cognitive impairment. Protein levels of PACAP, Sirtuin 3 (Sirt3), brain-derived neurotrophic factor (BDNF), and postsynaptic density 95 (PSD-95) were assessed by Western blot. In vitro, oxygen glucose deprivation (OGD) was used to simulate the ischemia/hypoxia state. HT22 cells were transfected with Sirt3 knockdown and overexpression to study the relationship between PACAP, Sirt3, and BDNF. In vivo, PACAP was administered intranasally to assess its protective effects on BCAS.

resultsThe study showed that the levels of PACAP, Sirt3, BDNF, and PSD-95 were decreased in the BCAS model of VaD. PACAP increased the protein levels of Sirt3, BDNF, PSD-95, Bcl-2, and Bax under OGD condition in vitro. Sirt3 regulated BDNF and synaptic plasticity. Intranasal PACAP increased the protein levels of PAC1, Sirt3, BDNF, and PSD-95 in vivo.

conclusionsThis study provides evidence that PACAP regulates synaptic plasticity and plays an antiapoptotic role through Sirt3.
