Effects of SNPs and alternative splicing within HGF gene on its expression patterns in Qinchuan cattle.

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
backgroundIdentification of genetic variants, including SNPs (Single Nucleotide Polymorphisms), CNVs (Copy Number Variations) and alternative splicing, within functional genes has received increasing attention in animal science research. HGF (Hepatocyte Growth Factor) is a very important growth factor that works as a mitogen or a morphogen during tissue growth, development and regeneration. However, to date, the functions of genetic variants within the bovine HGF gene, particularly their effects on mRNA expression, have not been determined well.
resultsThe present study aimed to perform association analysis between genetic variants and mRNA expression for the bovine HGF gene in Qinchuan cattle using various strategies, including PCR-RFLP (Restriction Fragment Length Polymorphism), qPCR (Quantitative Real-time quantitative PCR), TA cloning, DNA sequencing and bioinformatics analysis. A total of five SNPs were identified and only SV1 locus significantly affected HGF mRNA expression in fetal skeletal muscle (P < 0.05). Heterozygous genotype individuals showed significantly higher HGF expression (P < 0.05), which was significantly greater in the "CTCCAGGGTT" combined genotype than that in the "CCCCGGGGTT" combined genotype (P < 0.05). In addition, two alternative splicing variations, HGF-W and HGF-M, were identified, which resulted from alternative 3' splice sites of exon 5, and HGF-W showed higher mRNA levels than HGF-M in all tissues.
conclusionIn summary, genetic variations within the HGF gene affected mRNA expression. These findings provide new insight into the molecular characteristics and functions of bovine HGF.
