Cathepsins are a family of peptidase enzymes which are involved in the regulation of economically important traits in pigs. The aims of this study were (i) to identify the breed-specific frequency of polymorphisms in the cathepsin B (CTSB), L (CTSL), S (CTSS), and K (CTSK) genes in seven Ukrainian pig breeds, and (ii) to compare the cathepsins polymorphism frequency between Ukrainian breeds, a commonly used European meat breed (Piétrain) and a representative fat breed (Meishan). The Ukrainian breeds used were: Ukrainian Large White, Ukrainian Large Black, Poltava Meat, Myrgorod, Ukrainian Steppe Spotted, Ukrainian Landrace and Ukrainian Steppe White. The study established breed-specific differences in the allele frequencies and informativity of polymorphisms in the CTSB, CTSL, CTSS and CTSK genes in Ukrainian breeds. The following were of particular interest: locus CTSB in Ukrainian Large Black breed, locus CTSL in Ukrainian Steppe Spotted, and loci CTSS and CTSK in Myrgorod breed. The segregation of SNPs in meat quality candidate genes demonstrating intermediate or high polymorphism levels in the Ukrainian breeds Myrgorod, Ukrainian Steppe Spotted and Ukrainian Large Black is of interest for future evaluation in association studies with the view of complementing selection indexes with molecular information

Expression profiling of the GBP1 gene as a candidate gene for porcine reproductive and respiratory syndrome resistance Gol, Sofia; Estany Illa, Joan; Fraile Sauce, Lorenzo José; Pena i Subirà, Ramona Natacha (Wiley, 2015)A genomic region in pig chromosome 4 has been previously associated with higher viraemia levels and lower weight gain following porcine reproduction and respiratory syndrome virus (PRRSV) infection. The region includes the ...
Identification of signatures of selection for intramuscular fat and backfat thickness in two Duroc populations Kim, Eui-Soo; Ros Freixedes, Roger; Pena i Subirà, Ramona Natacha; Baas, Tom J.; Estany Illa, Joan; Rothschild, Max Frederick (American Society of Animal Science, 2015-07)Intramuscular fat (IMF) content is an important trait affecting the quality of pork. Two Duroc populations, one under positive selection for IMF and the other selected for decreased backfat but under stabilizing selection ...
Polymorphisms of the porcine cathepsins, growth hormone-releasing hormone and leptin receptor genes and their association with meat quality traits in Ukrainian Large White breed Balatsky, Viktor; Bankovska, Irina; Pena i Subirà, Ramona Natacha; Saienko, Artem; Buslyk, Tetyana; Korinnyi, Sergii; Doran, Olena (Springer Netherlands, 2016)Cathepsins, growth hormone-releasing hormone (GHRH) and leptin receptor (LEPR) genes have been receiving increasing attention as potential markers for meat quality and pig performance traits. This study investigated the ...
