      Background: The gut microbiota infuences host performance playing a relevant role in homeostasis and function of the immune system. The aim of the present work was to identify microbial signatures ...

    • Liver transcriptome profile in pigs with extreme phenotypes of intramuscular fatty acid composition 

      Ramayo-Caldas, Yuliaxis; Mach, Nuria; Esteve-Codina, Anna; Corominas, Jordi; Castelló, Anna; Ballester, Maria; Estellé, Jordi; Ibanez-Escriche, Noelia; Fernández, Ana I.; Pérez-Enciso, Miguel; Folch, Josep M (BMC Genomics, 2012-10-11) Genètica i Millora Animal
      Background: New advances in high-throughput technologies have allowed for the massive analysis of genomic data, providing new opportunities for the characterization of the transcriptome architectures. ...

    • Machine learning applied to transcriptomic data to identify genes associated with feed efficiency in pigs 

      Piles, Miriam; Fernandez‑Lozano, Carlos; Velasco‑Galilea, María; González‑Rodríguez, Olga; Sánchez, Juan Pablo; Torrallardona, David; Ballester, Maria; Quintanilla, Raquel (Genetics Selection Evolution, 2019-03-13) Genètica i Millora Animal; Nutrició Animal
      Background: To date, the molecular mechanisms that underlie residual feed intake (RFI) in pigs are unknown. Results from diferent genome‑wide association studies and gene expression analyses are not ...

    • Multi‑breed and multi‑trait co‑association analysis of meat tenderness and other meat quality traits in three French beef cattle breeds 

      Ramayo‑Caldas, Yuliaxis; Renand, Gilles; Ballester, Maria; Saintilan, Romain; Rocha, Dominique (Genetics Selection Evolution, 2016-04-23) Genètica i Millora Animal
      Background: Studies to identify markers associated with beef tenderness have focused on Warner–Bratzler shear force (WBSF) but the interplay between the genes associated with WBSF has not been explored. ...

    • Polymorphism in the ELOVL6 Gene Is Associated with a Major QTL Effect on Fatty Acid Composition in Pigs 

      Corominas, Jordi; Ramayo-Caldas, Yuliaxis; Puig-Oliveras, Anna; Pérez-Montarelo, Dafne; Noguera, José Luis; Folch, Josep M.; Ballester, Maria (PLoS ONE, 2013-01-14) Genètica i Millora Animal
