Evidence of stress in β cells obtained with laser capture microdissection from pancreases of brain dead donors.
Article in Islets, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
Isolated islets used for transplantation are known to be stressed, which can result from the circumstances of death, in particular brain death, the preservation of the pancreas with its warm and cold ischemia, from the trauma of the isolation process, and the complex events that occur during tissue culture. The current study focused upon the events that occur before the islet isolation procedure. Pancreases were obtained from brain dead donors (n = 7) with mean age 50 (11) and normal pancreatic tissue obtained at surgery done for pancreatic neoplasms (n = 7), mean age 69 (9). Frozen sections were subjected to laser capture microdissection (LCM) to obtain β-cell rich islet tissue, from which extracted RNA was analyzed with microarrays. Gene expression of the 2 groups was evaluated with differential expression analysis for genes and pathways. Marked changes were found in pathways concerned with endoplasmic reticulum stress with its unfolded protein response (UPR), apoptotic pathways and components of inflammation. In addition, there were changes in genes important for islet cell identity. These findings advance our understanding of why islets are stressed before transplantation, which may lead to strategies to reduce this stress and lead to better clinical outcomes.
