Flow Cytometry Analysis of SIRT6 Expression in Peritoneal Macrophages.
Article in Bio-protocol, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The sirtuin 6 has emerged as a regulator of acute and chronic immune responses. Recent findings show that SIRT6 is necessary for mounting an active inflammatory response in macrophages. In vitro studies revealed that SIRT6 is stabilized in the cytoplasm to promote tumor necrosis factor (TNFα) secretion. Notably, SIRT6 also promotes TNFα secretion by resident peritoneal macrophages upon lipopolysaccharide (LPS) stimulation in vivo. Although many studies have investigated SIRT6 function in the immune response through different genetic and pharmacological approaches, direct measurements of in vivo SIRT6 expression in immune cells by flow cytometry have not yet been performed. Here, we describe a step-by-step protocol for peritoneal fluid extraction, isolation, and preparation of peritoneal cavity cells, intracellular SIRT6 staining, and flow cytometry analysis to measure SIRT6 levels in mice peritoneal macrophages. By providing a robust method to quantify SIRT6 levels in different populations of macrophages, this method will contribute to deepening our understanding of the role of SIRT6 in immunity, as well as in other cellular processes regulated by SIRT6.
