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

Glucagon-like peptide 1 (GLP-1) is released from neuroendocrine cells in the intestine in the postprandial state and augments glucose-stimulated insulin secretion from pancreatic beta cells. To develop non-beta cells that exhibit physiologically regulated insulin secretion, we coexpressed the GLP-1 receptor and human insulin in primary rat pituitary cells using adenovirus-mediated gene transfer. The transduced cells were analyzed in a perifusion system and after transplantation into mice. Normal pituitary cells do not express the GLP-1 receptor as shown by the absence of GLP-1 receptor mRNA and the inability of GLP-1 to stimulate pituitary hormone secretion. Following transduction with an adenovirus carrying the GLP-1 receptor cDNA, the pituitary cells expressed functional GLP-1 receptors as reflected by the ability of GLP-1 to stimulate secretion of pituitary hormones. When both the GLP-1 receptor and human insulin were introduced, GLP-1 stimulated cosecretion of human insulin and endogenous pituitary hormones. GLP-1 was similar in potency to the hypothalamic-releasing hormones and stimulated hormone secretion in a dose-dependent fashion. In contrast to pancreatic beta cells, the hormone-releasing effect of GLP-1 on transduced pituitary cells was not dependent on the concentration of extracellular glucose. After transplantation of pituitary cells coexpressing human insulin and GLP-1 receptor into mice, enteral glucose stimulated insulin secretion. These results demonstrate a new approach to engineer physiologically regulated insulin secretion by non-beta cells.
