Study on Different Expression of HO-1 Gene of 70-weeks-old Changshun Blue-shelled Chicken in Different Tissues

In order to study the different expression of HO-1 gene in different tissues of 70-weeks-old Changshun Blue-shelled chickens. We collected nine (3 of each genotype) Changshun Blue-shelled chickens of 70-weeks-old as samples. The brain, liver, kidney, ovary, fallopian tube and uterus were collected, and total RNA of every tissue was extracted and reversed transcription to cDNA.The expression of HO-1 mRNA in different samples were detected by quantitative Real-time PCR.We compared the expression in the same tissues of different genotypes and in the different tissues of the same genotype. The results suggested that there were differences among different tissues of the same genotypes and different genotypes of the same tissues. The expression of HO-1 gene was highest in the liver, and there were significant difference in different genotype (P< 0.01).The expression level in the uterus of White-shelled chicken was extremely significantly higher than other two genotypes (P< 0.01),there was no significant difference between homozygous and heterozygous Blue-shelled chickens (P> 0.05).
