운동강도의 차이가 대장에서의 Heme oxygenase-1 발현에 미치는 영향: Oligonucleotide chip microarray analysis = Effect of exercise intensity pattems training on heme oxygenase-1 expression in Large intestine

다국어 초록 (Multilingual Abstract)

The purpose of this study is to identify how large intestine tissue effects to mRNA expression in Heme oxygenase-l (HO-1) due to differences in exercise intensity. To perform this experiment we divided Sprage-Dawley rats into 3 groups (control group (CON). low-intensity exercise group (LIE) and high-intensity exercise group (HIE)), and in 48 hours after 4 weeks treadmill exercise. the following experiment was performed with High through-put micro array analysis methods . 12,079 genes were chosen by filtering of the Rat ASI oligo chip 26.857 genes in this experiment Among 12.079 genes, we selected significant genes (p<.05) that were also expressed in the ways of clustering analysis and immunohistochemistry. With results of RT-PCR confirming and microarray analyzing, we derived that gene expression profiles of HO-l had been consistent. As a result of this experiment, we certainly identified that exercise effects to HQ-l expression in large intestine. mRNA expression was more expressed in high-intensity exercise group CHIE) than low-intensity exercise group (LIE), it seems that homeostasis maintains itself by properly removing oxygen radical. caused by high intensity exercise. through reduction of HO-l.
