Acetyl-CoA acyltransferase 1 () functions as a key regulator of fatty acid β-oxidation in peroxisomes by catalyzing the cleavage of 3-ketoacyl-CoA to acetyl-CoA and acyl-CoA, which participate in the extension and degradation of fatty acids. Thus, is an important regulator of lipid metabolism and plays an essential role in fatty acid oxidation and lipid metabolism. Our previous study findings revealed that is closely associated with the peroxisome proliferator-activated receptor () signaling and fatty acid metabolism pathways, which are involved in fat deposition in sheep, leading to our hypothesis that may be involved in fat deposition by regulating lipid metabolism.

Ovine Variation and Its Association With Flystrike Susceptibility.

Front Genet 2021 15;12:675305. Epub 2021 Jun 15.

Gene-Marker Laboratory, Faculty of Agriculture and Life Sciences, Lincoln University, Christchurch, New Zealand.

Flystrike is a major cost and a welfare issue for the New Zealand sheep industry. There are several factors that can predispose sheep to flystrike, such as having fleecerot, a urine-stained breech, and "dags" (an accumulation of fecal matter in the wool of the breech). The FABP4 gene () has been associated with variation in ovine fleecerot resistance, with a strong genetic correlation existing between fleecerot and flystrike occurrence. Read More

Int J Mol Sci 2021 Jun 25;22(13). Epub 2021 Jun 25.

Laboratorio de Genética Bioquímica (LAGENBIO), Instituto Agroalimentario de Aragón (IA2), Instituto de Investigación Sanitaria de Aragón (IISAragón), Universidad de Zaragoza, Miguel Servet 177, 50013 Zaragoza, Spain.

Diagnosis of transmissible spongiform encephalopathies (TSEs), or prion diseases, is based on the detection of proteinase K (PK)-resistant PrP in post-mortem tissues as indication of infection and disease. Since PrP detection is not considered a reliable method for in vivo diagnosis in most TSEs, it is of crucial importance to identify an alternative source of biomarkers to provide useful alternatives for current diagnostic methodology. Ovine scrapie is the prototype of TSEs and has been known for a long time. Read More
