Differential expression of lipid metabolism related genes in porcine muscle tissue leading to different intramuscular fat deposition.
Article in Lipids, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 49 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
Intramuscular fat (IMF) content affects meat quality and varies in different pig breeds. However, the underlying mechanisms of different IMF depositions in different genetic backgrounds of pigs have not been fully elucidated as yet. Lipid metabolism theoretically contributes to the variation of IMF content. The expression levels of genes and proteins as well as enzyme activities implicated in muscle lipid metabolism were investigated, which included lipogenetic genes (SREBP-1c and FAS), fatty acid transporting genes (H-FABP and A-FABP), fatty acid oxidative gene (CPT-1B) and lipolytic genes (ATGL and HSL) as well as the desaturated fatty acid gene (SCD). Longissimus muscle samples were collected from fatty Wujin pigs and lean Landrace pigs. Results showed that the average daily gain of Wujin pigs was lower than that of Landrace pigs. Wujin pigs had greater adipocyte diameter, IMF content and PUFA percentage than that of Landrace pigs. Compared with Landrace pigs, Wujin pigs exhibited higher expression levels, both in mRNA and protein, of FAS, SREBP-1c, SCD, A-FABP and H-FABP genes and lower expression levels of CPT-1B, HSL and ATGL genes. Overall, Wujin pigs possessed higher mRNA abundance, protein expression or enzyme activities of anabolism, fatty acid transportation and desaturation, and lower catabolism. Therefore, the mechanism of higher IMF content in fatty pigs may be due to the higher capacity of lipogenesis and fatty acid transportation and the lower capacity of lipolysis.
