초록
The HNF4α (hepatocyte nuclear factor 4, alpha) is a hepatic transcription factor related to the lipid metabolism and regulation of insulin secretion in humans. The current study about commercial broiler reported that the A543G single nucleotide polymorphism (SNP) within HNF4α gene has an effect on fat deposition and wing yield in the chicken. This study was performed to investigate the association between the SNP within HNF4α gene and growth trait and to verify the applicability as a molecular marker for the improving the performance in Korean native chickens (KNCs). A total of 764 KNCs was collected from the livestock farm of Gyeongnam National University of Science and Technology in Korea and genotyped by PCR-RFLP. The body weight measured at birth, 2, 4, 6, 8, 10, 12, 14, 15, 16, 18, 20, 24, 28, 32, 36, and 40 weeks of age for the association analysis between chicken growth and the SNP genotype. Statistical analysis of the SNP with phenotypic traits was performed using SAS program. The KNC strain was classified by the genotypes of the A543G SNP. The frequencies of three genotypes were 0.47 (AA), 0.43 (AG) and 0.10 (GG), respectively. The SNP of HNF4α has highly significant association (p<0.001) with all-round growth in KNCs. These results suggest that the A543G SNP within HNF4α gene could be a genetic marker for the breeding in Korean native chickens.
Abstract
The HNF4α (hepatocyte nuclear factor 4, alpha) is a hepatic transcription factor related to the lipid metabolism and regulation of insulin secretion in humans. The current study about commercial broiler reported that the A543G single nucleotide polymorphism (SNP) within HNF4α gene has an effect on fat deposition and wing yield in the chicken. This study was performed to investigate the association between the SNP within HNF4α gene and growth trait and to verify the applicability as a molecular marker for the improving the performance in Korean native chickens (KNCs). A total of 764 KNCs was collected from the livestock farm of Gyeongnam National University of Science and Technology in Korea and genotyped by PCR-RFLP.
