The effect of the PLIN1 gene on the metabolism and mitochondria of porcine skeletal muscle satellite cells.
Article in Genes & genomics, 2022. 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
backgroundPerilipin 1 (PLIN1) is a lipid droplet scaffolding protein that plays a regulatory role in fat decomposition and mitochondrial function.
objectiveIn this study, the effects of PLIN1 gene knockout (PLIN1-KO) and PLIN1 gene overexpression (PLIN1-EX) on cell metabolism and mitochondrial function in porcine skeletal muscle satellite cells were assessed.
methodsPorcine skeletal muscle satellite cells were used as the control group (NC). The expression of mitochondrial function-related proteins was detected by western blot. Apoptosis, cell cycle, mitochondrial function-related indices, mitochondrial structure, and morphology were measured by flow cytometry.
resultsOur results demonstrated that stable expression of the PLIN1 gene in skeletal muscle satellite cells is critical to maintaining cell metabolism and mitochondrial function. After knockout and overexpression of the PLIN1 gene, the anti-apoptotic ability of cells was enhanced, and the metabolic activity of the cells was accelerated, but at the cost of mitochondrial structural damage, reduction in the number of mitochondria, and decreased mitochondrial function.
conclusionThis study explored the effect of the PLIN1 gene on the mitochondria and metabolism of porcine skeletal muscle satellite cells and provided a theoretical basis for the subsequent study of the effects of PLIN1 on muscle tissue development and meat quality.
