Pigs are the most basic livestock that provide the protein they need, since they were raised in the eastern part of India about 9,000 years ago, and have been breed in accordance with the times and circumstances and the preferences of the people. There are many factors that determine meat quality and weight of pigs. Among them, meat level is the most important measure of muscle fat content and meat weight is the most important measure of meat weight. Red meat is the favorite meat color of consumers. It is also a predominantly meat quality trait.

In order to produce commercially available finishing pigs, breeding pigs with excellent traits such as body weight gain, immune ability, number of litter, milk yield, and meat quality have been breeded to produce new kinds of pigs. However, the breeding process is complicated and takes a long time to obtain the breed having the desired traits. Accordingly, techniques for improving the meat quality of livestock have been actively carried out by modifying the genotype. As a result, the quality of the pigs is improved by using the SNP traits of the genes involved in the meat quality, And an improved method of producing pigs have been developed (Korean Patent Registration No. 10-1457942). However, a method for easily and effectively improving the meat quality of pigs has not yet been developed, and a method for improving the meat quality of pigs using the MYH3 gene has not been developed.

Under these circumstances, the present inventors have made extensive efforts to develop a method for improving the meat quality of livestock by modifying the genetic traits, and as a result, they have found that the MYH3 gene is a gene determining the meat quality of pigs, Of the present invention showed that the meat content and redness of the meat were improved compared to the wild type, and that the meat quality could be improved by using a recombinant vector containing the gene.

From the above results, it was found that the MYH3 gene is a major gene that determines the red color and the intramuscular fat content, among the meat quality traits of pigs.

Example 3: Construction of transgenic mouse into which porcine MYH3 gene was inserted

In order to confirm the in vivo activity of the gene, the MYH3 gene was identified as a gene determining the redness and muscle fat content among the meaty traits of pigs in Example 2, Transgenic mice transfected with the porcine MYH3 gene were prepared by the method according to 3-2.

Example 3-1. Production of Transformation Vector

First, a recombinant CAGGS-MYH3-Flag expression vector into which a MYH3 gene was inserted was prepared in order to construct a transgenic mouse into which a porcine MYH3 gene was inserted.

Specifically, in order to prepare a vector overexpressing the porcine MYH3, the whole base sequence of the mRNA of the porcine MYH3 gene was confirmed, and the DNA fragments were artificially synthesized by dividing into four portions in total. The first fragment was 1,417 bp, which was artificially synthesized by adding XbaI and BglII enzyme sites on both ends to both ends. BglII and SalI were synthesized at 1,745 bp for the second fragment, SalI and SacII at 1,777 bp for the third fragment, and SacII and EcoRI at the fourth and final 944 bp. The completed four DNA fragments were ligated using an enzyme site artificially bound to the ends to finally complete a gene fragment containing the entire mRNA of the porcine MYH3 gene.

Then, the CAGGS-EGFP-Puro vector as shown in Fig. 5 was digested with XbaI and EcoRI for introduction into the overexpressed vector, and then a whole fragment of the prepared porcine MYH3 gene mRNA was inserted to finally produce a porcine MYH3 transformant vector (Fig. 6).

The structure of the vector is shown in FIG. 6, and the nucleotide sequence of the vector is shown in SEQ ID NO: 2.

As a result, as shown in FIG. 7 (a), transgenic mice (21, 24, 26, 27, and 28) in which the MYH3 gene was inserted and expressed mRNA could be identified.

Example 3-2-3. Confirmation of introduction of foreign gene through analysis of protein expression

In order to confirm whether the MYH3 gene was introduced into the transgenic mouse prepared in Example 3-2-1, the expression of the gene was analyzed.

Specifically, after removing the fuzzy muscle tissue of the wild-type mouse (WT) and the transgenic mouse (TG), the tissue was degraded by adding the protease inhibitor to the RIPA buffer and ultrasonication. Subsequently, the protein and the protein were separated through a low-temperature centrifuge to recover proteins from the supernatant. The recovered protein was quantified using a BSA protein assay reagent (bio-rad), and then heated at 100 ° C. for about 10 minutes with 4 × protein loading buffer (1 ×). To perform Western blotting using the prepared protein, the protein was subjected to SDS-PAGE gel for about 2 hours. Then, the proteins were transferred to a PVDF membrane and blocked with 5% skim milk for 1 hour. The primary antibody (Anti-Flag M2 (F1804, Sigma-Aldrich) and b-actin , Cell signaling) was added and reacted overnight at 4 ° C. The next day, the cells were washed with TBST solution, reacted with the secondary antibody for 2 hours, treated with ECL reagent, and the signal of the antibody bound to the protein was confirmed using a LAS-300 luminescent image analyzer system (Fujifilm). The secondary antibodies used in the experiments were used differently according to the primary antibodies.

As a result, as shown in FIG. 7 (b), it was confirmed that the expression level of the MYH3 gene was the highest among the transgenic mice at 24 hours. Thus, the 24 transgenic mouse having the highest expression level of the transgene was used for breeding after mating, and its appearance is shown in FIG.

Example 3-3. Identification of muscle type in transgenic mice

In order to confirm the function of the MYH3 gene related to the determination of the meat quality trait, the meat quality of the transgenic mouse prepared in Example 3-2 was examined.

First, as can be seen from FIG. 9 (a), it was confirmed that the muscles of the hind legs of the pig MYH3 transgenic mice (W: TG) were redder than the wild type mice (WT).

Afterwards, ATPase staining was performed to further confirm the muscle morphology. The hindlimb muscles of wild-type and transgenic mice were harvested, treated overnight in a 30% sucrose solution, tissue-sectioned to 10 쨉 m at -25 째 C using an OCT compound, And fixed with PEA for 1 hour. After washing with running water for 10 minutes and washing with 60% isopropanol, ATPase stain lyopilized powder for histoenzymatic reaction kit (Bio-optica) was used according to the manufacturer's instructions Experiments were performed.

As a result, as shown in FIG. 9 (b), it was confirmed that the transgenic mouse (right; TG) in which the gene was inserted contained more red muscle in the hind limb muscle than the wild type mouse (left; WT) .

In addition, Oil Red O staining was performed to determine the distribution of fat in muscle tissue. Specifically, the tissue slice was reacted with 0.3% Oil Red O solution for 1 hour.

As a result, as shown in FIG. 9 (c), it was confirmed that the degree of staining in the transgenic mouse (TG) was stronger than in the wild type mouse (left; WT) Of the total population.

These results suggest that MYH3 gene is a causative gene that accumulates red muscle and improves redness and accumulates muscle fat content.

Example 3-4-2. Identification of expression patterns of fat accumulation patterns and related genes

In addition, in order to confirm the function of the MYH3 gene in the determination of meat quality traits, the fat accumulation pattern of the transgenic mouse prepared in Example 3-2 and the expression pattern of the related gene were examined.

First, to confirm the fat accumulation pattern, we tried to identify the morphology of the tissue, and we performed H & E (Hematoxylin and eosin) staining. Paraffin embedding was carried out using the muscle tissues of wild-type mouse (WT) and transgenic mouse (TG), and the tissue was cut into a thickness of 4 탆. Then, paraffin was removed by using xylene, dehydrated in the order of 100%, 95%, 75% and 50% alcohol, and then washed in running water for 5 minutes. Thereafter, the cells were treated with Myyer's hematoxylin solution for 1 minute, washed with flowing water for 20 minutes, treated with esoin for 1 minute, followed by dehydration and clearing, And the state of staining was confirmed.

In order to confirm the expression pattern of the fat accumulation gene in the muscle tissue of the transgenic mouse, qRT-PCR was performed by the method according to Example 2-3. The primers used at this time are listed in Table 4 below.

The amplified product was electrophoresed on 2% agarose gel containing EtBr (ethidium bromide), and then amplified under UV.

Then, the 'A ▼ CGT' portion of the base sequence of the causative base mutation was cleaved by using HpyCH4IV restriction enzyme. The amplified PCR product was digested with restriction enzymes (HpyCH4IV). The restriction enzyme reaction conditions were 3 μl of PCR amplification product, 1 μl of 10X buffer, 0.3 μl of restriction enzyme and 5.7 μl of DW, Lt; 0 &gt; C overnight. Electrophoresis was performed on 2% agarose gel containing EtBr (ethidium bromide) to confirm the cleavage pattern of the landrace and Jeju native pig MYH3 gene by restriction enzyme.

As a result, as shown in FIG. 12, it was confirmed that the LANDLACE pig having poor meat quality did not cleave the gene, resulting in one band at 250 bp (1/1; non-cleaved type) The Korean traditional pig (KNP) was confirmed to have two bands at 167 and 77 bp by cleavage of the gene (2/2; truncated form). In addition, it was confirmed that the hybrid cultivars of Landrace and Jeju native pigs were represented by two bands at 250 and 167 bp (1/2, cut type).

Through the above results, it was confirmed that the pigs could be distinguished from the native pigs by confirming the mutation of MYH3, which is a gene that determines the meat quality of pigs, as well as judging the meat quality of the pigs.
