목적 : 한국인 여성에서 자궁내막증과 관련된 유전자를 알아보기 위하여 자궁내막증 환자와 대조군의 자궁내막 및 자궁내막증 조직에서 Ang-1과 Ang-2의 mRNA발현 차이를 분석하였다.연구 방법 : 자궁내막증 환자와 대조군의 자궁내막에서 총 RNA를 추출하여 cDNA로 역전사하였다. Ang- 1과 Ang-2 mRNA의 발현의 차이를 Quantitative Competitive RT-PCR로 비교하였고, 선형회귀분석과 Kruskal- Wallis 검정, Mann-Whitney U검정으로 통계분석 하였다.결과 : 자궁내막증 환자와 대조군의 월경주기에 따른 자궁내막에서의 Ang-1 mRNA을 정량분석한 결과 난포기와 황체기간의 mRNA 발현의 차이는 없었다. 난포기 자궁내막증 환자의 자궁내막에서 대조군의 자궁내막보다 Ang-1 mRNA 발현이 통계적으로 유의하게 높았다 (P=0.049). 자궁내막증 환자와 대조군의 월경주기에 따른 자궁내막에서의 Ang-2 mRNA의 정량분석한 결과 난포기와 황체기간의 mRNA 발현의 차이는 없었다. 난포기 (P=0.048)와 황체기 (P=0.006) 모두 대조군의 자궁내막에서 난포기 자궁내막증 환자의 이소성 자궁내막보다 Ang-2 mRNA 발현이 통계적으로 유의하게 높았다.
Abstract
Objective : To investigate the mRNA expression of Angiopoietin (Ang)-1 and Ang-2 in ectopic and eutopic endometrium from women with or without endometriosis throughout the menstrual cycle. Methods : Total RNA was extracted and reverse transcribed into cDNA. The expression of Ang-1 and Ang-2 was examined by quantative competitive PCR (QC PCR) and each result was analyzed by Kruskal- Wallis analysis and Mann-Whitney U-test. Results : The expression of Ang-1 mRNA was statistically significantly higher in endometrium of follicular phase from women with endometriosis compared to that from normal ones in the follicular phase. Endometriotic tissues expressed significantly lower Ang-2 mRNA compared to endometrium from women without endometriosis. Conclusion : We suggested that the expression of Ang-1 mRNA could be associated with the pathogenesis of endometriosis and might have a role as neovascularizaton and survival of ectopic endometrium.
