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 trigeminal ganglion (TG) can express and release calcitonin gene-related peptide (CGRP), an important neuropeptide that plays a crucial role in migraine attack and cluster headache. Activation of rat TG increases CGRP expression. However, the regulatory mechanism of CGRP expression in TG neurons remains to be explored. This study aims to evaluate the involvement of mitogen-activated protein kinase (MAPK) pathways in CGRP upregulation after rat TG organ culture. Rat TG was cultured alone for 24 h or cultured in combination with MAPK inhibitors, tumor necrosis factor α (TNF-α), or interleukin 1β (IL-1β) for 24 h. CGRP protein was determined using immunohistochemistry. The mRNA levels of CGRP, TNF-α, and IL-1β were analyzed through real-time quantitative polymerase chain reaction. MAPK phosphorylation was detected via western blot. After rat TG organ culture, the expressions of CGRP, TNF-α, and IL-1β were upregulated at 24 h. The phosphorylation of extracellular signal-regulated kinases (ERK1/2), P38, and c-jun N-terminal kinases (JNK) significantly increased at 30 min compared with fresh rat TG. In addition, both CGRP expression and phosphorylation of ERK1/2, P38, and JNK were enhanced obviously after rat TG treatment with TNF-α or IL-1β compared with fresh rat TG. However, they decreased markedly after rat TG pretreatment with PD98059 (ERK1/2 inhibitor), SB203580 (P38 inhibitor), or SP600125 (JNK inhibitor) compared with rat TG co-culture with TNF-α or IL-1β. In conclusion, the elevated CGRP expression after rat TG organ culture can be regulated via MAPK pathways. The findings provide insight into the molecular mechanisms and experimental evidence for therapeutic targets of migraine.
