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

Adrenomedullin (AM) and calcitonin gene-related peptide (CGRP) have structural similarities, interact with each others receptors (calcitonin receptor-like receptor (CLR)/receptor-activity-modifying proteins (RAMPs)) and show overlapping biological activities. AM and CGRP receptors are chiefly coupled to cAMP production. In this study, a method of primary dissociated cell culture was used to investigate the presence of AM and CGRP receptors and their effects on cAMP production in embryonic spinal cord cells. Both neuronal and non-neuronal CLR immunopositive cells were present in our model. High affinity, specific [(125)I]-AM binding sites (K(d) 79 +/- 9 pM and B(max) 571 +/- 34 fmol mg(-1) protein) were more abundant than specific [(125)I]-CGRP binding sites (K(d) 12 +/- 0.7 pM and B(max) 32 +/- 2 fmol mg(-1) protein) in embryonic spinal cord cells. Specific [(125)I]-AM binding was competed by related molecules with a ligand selectivity profile of rAM > hAM(22-52) > rCGRPalpha > CGRP(8-37) >> [r-(r(*),s(*))]-N-[2-[[5-amino-1-[[4-(4-pyridinyl)-1-piperazinyl]carbonyl]pentyl]amino]-1-[(3,5-dibromo-4-hydroxyphenyl)methyl]-2-oxoethyl]-4-(1,4-dihydro-2-oxo-3(2H)-quinazolinyl)-,1-piperidinecarboxamide (BIBN4096BS). Specific [(125)I]-CGRP binding was competed by rCGRPalpha > rAM > or = CGRP(8-37) > or = BIBN4096BS > hAM(22-52). Cellular levels of cAMP were increased by AM (pEC(50) 10.2 +/- 0.2) and less potently by rCGRPalpha (pEC(50) 8.9 +/- 0.4). rCGRPalpha-induced cAMP accumulation was effectively inhibited by CGRP(8-37) (pA(2) 7.63 +/- 0.44) and hAM(22-52) (pA(2) 6.18 +/- 0.21) while AM-stimulation of cAMP levels was inhibited by CGRP(8-37) (pA(2) 7.41+/- 0.15) and AM(22-52) (pA(2) 7.26 +/- 0.18). BIBN4096BS only antagonized the effects of CGRP (pA(2) 8.40 +/- 0.30) on cAMP accumulation. These pharmacological profiles suggest that effects of CGRP are mediated by the CGRP(1) (CLR/RAMP1) receptor in our model while those of AM are related to the activation of the AM(1) (CLR/RAMP2) receptor subtype.
