Description
Technical Field
The invention belongs to the technical field of cow ketosis resistance breeding, and relates to a molecular marker related to the concentration of beta-hydroxybutyric acid in cow blood and application thereof.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
Ketosis (ketosis) is a nutritional metabolic disease occurring in perinatal cows based on the major pathologies of energy negative balance, fat mobilization, hyperketonemia, hypoglycemia and disorders of liver fat metabolism. Ketosis occurs frequently in high-producing cows, and has a negative effect on the health, reproductive capacity and milk yield of the cows. In the early lactation period of high-yield cows, the milk yield is increased, a large amount of lactose is synthesized, so that glucose in a body is mobilized to synthesize lactose, and the sugar ingested by the body is insufficient, so that the energy is deficient, a large amount of fatty acid in the body is promoted to be decomposed, and the deficient energy is compensated. At the moment, the fat reserve of the body is excessively mobilized, a large amount of non-esterified fatty acid is oxidized, so that a large amount of ketone bodies are generated in the liver of the cow, but the rate of metabolizing the non-esterified fatty acid by the body is limited, so that the ketone bodies in the blood, urine and milk of the cow are accumulated, and the content of the ketone bodies is increased. The ketone body is an intermediate product generated when fatty acid is decomposed and oxidized in liver cells, and comprises three components of acetoacetic acid, beta-hydroxybutyric acid (BHB) and acetone. The BHB concentration in blood was used as a gold standard indicator of ketosis, and a threshold of 1.2mmol/L was used to identify ketosis cows (Van der Drift et al, 2012).
Ketosis is resistant, but its heritability is low, between 0.02 and 0.06, and it is difficult to achieve effects by direct selection based on phenotype (Koeck et al, 2013; Parker Gaddis et al, 2014). BHB is an indicative trait of ketosis with moderate heritability of 0.07-0.40(Oikonomou et al, 2008; Jamrozikik et al, 2016). Therefore, indirect selection of ketosis is more effective by using BHB as an index trait, and better genetic gain can be obtained than direct selection according to ketosis. Huang et al (2019) use the concentration of beta-hydroxybutyrate in cow blood as a defining standard, and carry out whole genome association analysis by adopting binary traits of a healthy group and a ketosis group to obtain candidate genes related to ketosis, such as GCH 1. Yan et al (2020) select 4 healthy cattle and 8 ketosis cattle according to the concentration of beta-hydroxybutyric acid in blood, perform transcriptome sequencing and whole genome correlation analysis, and newly identify 5 ketosis candidate genes such as GRINA. Whether the candidate genes affect ketosis resistance remains to be verified. Screening and identifying candidate genes and molecular markers related to the concentration of beta-hydroxybutyric acid in the blood of the dairy cattle is the basis for developing the application of the dairy cattle ketosis resistance molecular breeding.
Disclosure of Invention
UBA6 is ubiquitin activating enzyme, participates in ubiquitination modification, and plays an important role in embryonic development, nervous system development and function, and metabolic activity. Ubiquitination, as a post-translational modification of proteins, can play a regulatory role in liver lipid metabolism. Ubiquitination modification plays an important regulatory role in the activation of adenylate activated protein kinase (AMPK). The ubiquitination degradation mechanism is a function that AMPK increases the activity of endoplasmic reticulum anchoring protein through phosphorylation, and further inhibits liver lipid synthesis, and is a mechanism that protein posttranslational modification regulates fatty acid synthesis through a ubiquitination degradation pathway.

By exploring and obtaining the SNP locus related to the concentration of the beta-hydroxybutyric acid in the UBA6 gene, the cow with ketosis resistance can be selected based on the SNP locus, and then the cow breeding, genetic improvement and marker assistance are carried out, so that the method has better application value.
