This study was designed to characterize the DNA polymorphisms of the melanocortin-1 receptor (MC1R) gene in indigenous Saudi Arabian sheep breeds exhibiting different color coats, along with individua...
In the present study, we investigated the effect of PPAR ligands on progesterone (P4) and 17β-estradiol (E2) secretion, as well as 3β-hydroxysteroid dehydrogenase/Δ(5)-Δ(4) isomerase (3β-HSD) mRNA exp...
In the last few decades, transgenic animal technology has witnessed an increasingly wide application in animal breeding. Reproductive traits are economically important to the pig industry. It has been...
The peroxisome proliferator-activated receptor gamma (PPARγ) gene plays an important role in the biosynthesis process controlled by a number of fatty acid transcription factors. This study investigate...
The melatonin receptors are G protein-coupled receptors (GPCR) that bind melatonin. Three types of melatonin receptors have been cloned. The MTNR1A (or Mel1A or MT1) and MTNR1B (or Mel1B or MT2) recep...
Adipose tissue deposited within muscle fibers, known as intramuscular fat (IMF or marbling), is a major determinant of meat quality and thereby affects its economic value. The biological mechanisms th...
While athletic abilities such as speed, endurance and recovery are important in the horse, genes related to these abilities have not been extensively investigated. Here, we characterized the horse per...
Protease-activated receptor-2 (PAR-2) is a member of the G-protein-coupled receptor family. The proteases that activate PAR-2 are released during inflammation and injury, with PAR-2 regulating the res...
This study was conducted to examine calcitonin (CT) receptor binding in the membrane fraction of the endometrium of the shell gland of laying hens by the use of [125I] CT binding assays. Specific [125...
We investigated the effect of the prolactin receptor gene (PRLR) on total number of born (TNB), number of born alive (NBA) and number of weaned (NW) piglets in Large White (LW), White Meaty (WM) and L...
We investigated the effect of ESR gene-based selection on an improvement of litter size in the herds in real (non-experimental) conditions. The pigs were selected for three years. In the tested popula...
To determine whether a link exists between reproductive seasonality and the structure of the melatonin receptor 1A (MTNR1A) gene, the latter was studied in nonseasonal estrous breeds (Small Tail Han a...
The quality characteristics of semen are important indicators of the fertility of a boar. Development of genetic markers for the semen quality in boars will be beneficial to the improvement of porcine...
We investigated the effect of oestrogen receptor (ESR) gene on total number of born (TNB), number of born alive (NBA) and number of weaned (NW) piglets in Large White (LW), White Meaty (WM) and Landra...
Melatonin regulates circadian rhythms and reproduction changes in seasonally reproductive mammals through binding to high-affinity, G-protein-coupled receptors. Small Tail Han sheep that has significa...
