Pharmacological characterization of beta2-adrenoceptor in PGT-beta mouse pineal gland tumour cells.
Article in British journal of pharmacology, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
1. The adrenoceptor in a mouse pineal gland tumour cell line (PGT-beta) was identified and characterized using pharmacological and physiological approaches. 2. Adrenaline and noradrenaline, adrenoceptor agonists, stimulated cyclic AMP generation in a concentration-dependent manner, but had no effect on inositol 1,4,5-trisphosphate production. Adrenaline was a more potent activator of cyclic AMP generation than noradrenaline, with half maximal-effective concentrations (EC50) seen at 175+/-22 nM and 18+/-2 microM for adrenaline and noradrenaline, respectively. 3. The addition of forskolin synergistically stimulated the adrenaline-mediated cyclic AMP generation in a concentration-dependent manner. 4. The pA2 value for the specific beta2-adrenoceptor antagonist ICI-118,551 (8.7+/-0.4) as an antagonist of the adrenaline-stimulated cyclic AMP generation were 3 units higher than the value for the betaI-adrenoceptor antagonist atenolol (5.6+/-0.3). 5. Treatment of the cells with adrenaline and forskolin evoked a 3 fold increase in the activity of serotonin N-acetyltransferase with the peak occurring 6 h after stimulation. 6. These results suggest the presence of beta2-adrenoceptors in mouse pineal cells and a functional relationship between the adenylyl cyclase system and the regulation of N-acetyltransferase expression.
