Delayed body development with reduced triglycerides levels in leptin transgenic pigs.
Article in Transgenic research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Leptin is a well-known adipokine that plays critical role in adiposity. To further investigate the role of leptin in adiposity, we utilized leptin overexpressing transgenic pigs and evaluated the effect of leptin on growth and development, fat deposition, and lipid metabolism at tissue and cell level. Leptin transgenic pigs were produced and divided into two groups: elevated leptin expression (leptin ( +)) and normal leptin expression group (control). Results indicated that leptin ( +) pigs had elevated leptin protein and mRNA expression levels and exhibited sluggish growth and development followed by decreased subcutaneous fat thickness, low serum triglycerides, saturated, unsaturated fatty acids and high cholesterol esters (p < 0.05). There were differences in the lipid metabolism related genes at different fat depots, including upregulation of PPARγ, AGPAT6, PLIN2, HSL and ATGL in subcutaneous, PPARγ in perirenal, and FAT/CD36 and PLIN2 in mesenteric adipose tissues and downregulation of AGPAT6 and ATGL in perirenal and AGPAT6 in mesenteric adipose tissues (p < 0.05). Additionally, in-vitro cultured leptin ( +) preadipocytes exhibited upregulation of PPARγ, FAT/CD36, ACACA, AGPAT, PLIN2, ATGL and HSL as compared to control (p < 0.05). These findings suggested that homeostasis imbalance in lipolysis and lipogenesis at adipose tissue and adipocytes levels led to low subcutaneous fat depots in leptin overexpression pigs. These pigs can act as model for obesity and related metabolic disorder.
