Nitric oxide inhibits ghrelin-induced cell proliferation and ERK1/2 activation in GH3 cells.

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
Ghrelin stimulates growth hormone release and cell proliferation, which strongly supports a significant role for this peptide in the control of growth hormone-releasing adenomas function and growth. Nitric oxide can influence the stimulatory effects of ghrelin on growth hormone secretion in growth hormone-releasing adenomas. However, the effect of nitric oxide (NO) on ghrelin-induced cell proliferation and the mechanism of this effect in the adenoma were not clarified. In this study, we observed that ghrelin, at a concentration of 10⁻⁹ to 10⁻⁶ M, significantly increased BrdU incorporation into rat GH3 cells. A NO donor, S-nitroso-N-acetylpenicillamine (SNAP), blunted basal, and ghrelin-induced cell proliferation. A blocker of NO synthase, Nw-nitro-L-arginine methyl ester hydrochloride (NAME), had no influence on these actions. The activation of extracellular signal-regulated kinase (ERK) 1/2 was examined by western blotting. The results showed that SNAP reduced ghrelin-stimulated ERK1/2 activation but NAME had no influence on this activation. Together, this study indicates that NO inhibited ghrelin-induced cell proliferation by blocking ERK1/2 activation in GH3 cells.
