Abstract:

The expression patterns of mitochondrial marker-succinate dehydrogenase(SDH) in different tissues of Datong yak at early development stage were investigated under the plateau hypoxia environment.Pregnant yaks at 4-month-old and yaks at 1-day-old were sampled,genetic mRNA expression quantities (SDHASDHBSDHC and SDHD) of placental tissues,cardiac muscle,skeletal muscle,liver and brain tissues of fetuses at 4-month-old and yaks at 1-day-old were determined using qRT-PCR,the correlation between mitochondrial SDH mRNA expression qualities and energy metabolism in different organs and tissues were researched.The results showed that cardiac muscle mitochondrial genetic mRNA expression quantities (SDHASDHBSDHC and SDHD) of yaks at 1-day-old were significantly higher than those of fetuses at 4-month-old,cerebral mitochondrial genetic mRNA expression quantities (SDHASDHBSDHC and SDHD) of fetuses at 4-month-old were significantly higher than those of yaks at 1-day-old.SDH gene expression patterns suggested that gene (SDHASDHBSDHC and SDHD) transcription levels were up-regulated expression between the brain of fetus at 4-month-old and cardiac muscle of yak at 1-day-old,which was reflected on exuberant energy metabolism regulation activities between the brain of fetus at 4-month-old and cardiac muscle of yak at 1-day-old.
