Reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) is the most reliable molecular biology technique for assessment of mRNA expression levels. However, to obtain the accurate RT-qPCR results, the expression levels of genes of interest should be normalized with appropriate reference genes and optimal numbers of reference genes.(More)
Epoxide hydrolase 1 (EPHX1) plays an important role in both the activation and detoxification of exogenous chemicals. Reverse transcription-polymerase chain reaction (RT-PCR) analysis showed that the highest level of EPHX1 expression occurred in Berkshire liver, which is an organ that plays a key role in detoxification. We examined EPHX1 SNPs to analyze(More)
Improvement in litter size has become of great interest in the pig industry because fecundity is directly related to sow reproductive life. Improved reproduction has thus been achieved by elucidating the molecular functions of genes associated with fecundity. In the present study, we identified differentially expressed genes (DEGs) via transcriptomic(More)
In mammals, Squalene epoxidase (SQLE) is an enzyme that converts squalene to 2,3-oxidosqualene, in the early stage of cholesterol generation. Here, we identified single nucleotide polymorphisms (SNPs) in the SQLE gene (c.2565 G > T) by RNA Sequencing from the liver tissue of Berkshire pigs. Furthermore, we found that homozygous GG pigs expressed more SQLE(More)
Increasing litter size is of great interest to the pig industry. DNA methylation is an important epigenetic modification that regulates gene expression, resulting in livestock phenotypes such as disease resistance, milk production, and reproduction. We classified Berkshire pigs into two groups according to litter size and estimated breeding value: smaller(More)
The NADPH-dependent reduction activities of two paralogous pig AKR1C1s with and without 19 additional amino acid residues in C-terminus were evaluated against steroid hormones including 5alpha-dihydrotestosterone, testosterone, progesterone, androstenedione and 5alpha-androstane-3.17-dione, which act as substrates of the AKR1C1S. Among the hormones, the(More)
Changes in meat quality traits are strongly associated with alterations in postmortem metabolism which depend on genetic variations, especially nonsynonymous single nucleotide variations (nsSNVs) having critical effects on protein structure and function. To selectively identify metabolism-related nsSNVs, next-generation transcriptome sequencing (RNA-Seq)(More)
