콩의 대표적인 이소플라본인 genistein과 daidzein에 의해 암세포 생존율에 미치는 영향을 확인하기 위하여, HCT116 세포주에 genistein과 daidzein을 농도 의존적으로 처리하였다. Genistein은 처리한 농도 의존적으로 암세포 생존율을 감소시켰으며, 이에 반해 daidzein은 세포생존율에 큰 변화를 보여주지는 못하였다. 이전의 마이크로어레이 실험 결과에 의하면, 50 μM의 genistein에 의해 2배 이상 증가되는 유전자 71개, 2배 이상 감소되는 유전자 64개가 검색되었다. 이중 3개의 유전자(DKK-1, ATF3 그리고 NAG-1)를 선택하여, 마이크로어레이 실험 결과를 검증하기 위하여 RT-PCR을 수행하였다. RT-PCR 결과 마이크로어레이 결과와 모두 일치함을 증명하였다. 한편, genistein과 daidzein에 의한 병합처리에 의해 암세포생존에 미치는 영향을 확인하였다. 그 결과 병합처리에 의한 상승적인 세포독성 효과를 확인하였다. RT-PCR과 real-time PCR의 결과 genistein과 daidzein의 병합처리에 의해 항암유전자인 NAG-1 유전자가 상승적으로 발현이 증가됨을 확인하였다. 이러한 결과는 이소플라본뿐만 아니라 대두제품에 의한 암 화학예방법의 기전을 이해하는 도움을 줄 것으로 생각된다. To investigate whether isoflavone genistein and daidzein could affect cancer cell viability, human colorectal HCT116 cells were incubated with genistein or daidzein in a dose-dependent manner. Genistein decreased cancer cell viability in a dose-dependent manner, whereas daidzein did not show dramatic cytotoxic effects. We also found that 71 genes were up-regulated more than 2-fold, whereas 64 genes were down-regulated more than 2-fold with 24 hr of 50 μM genistein treatment by our previous microarray data. Among the up-regulated genes, we selected 3 genes (DKK1, ATF3 and NAG-1) and performed RT-PCR to confirm microarray data. The results of RT-PCR were highly correlated with those of the microarray experiment. In addition, we investigated whether a combination treatment of genistein and daidzein could affect cancer cell viability. Surprisingly, the combination treatment did show synergistic cytotoxic effects detected by MTS assay. The results of RT-PCR and real-time PCR indicate that a combination of genistein and daidzein can synergistically induce NAG-1 expression in HCT116 cells. This result implies that NAG-1 induction is highly associated with synergistic cytotoxic effects induced by a combination treatment of genistein and daidzein. Overall, these results may provide a clue in explaining the anti- cancer activity of soy bean in human colorectal cancer.

목적 : 산전 유전 및 염색체 질환을 진단할 수 있는 융모막 검사에는 경자궁경부방법과 경복식방법이 있다. 본 연구에서는 두 방법의 융모막 검사 중 보다 안전하고 효율적인 방법을 알아보고자 실시하였다. 연구방법 : 본 연구에서는 1991년 1월에서 1998년 6월까지 전북대학교병원 산부인과에서 산전진단의 적응증에 해당하는 788명의 임신여성 중 의무기록지 분석이 가능한 633명의 여성을 대상으로 하였고 이중 490명은 경자궁경부 융모막 검사를 143명은 경복식 융모막검사를 실시받았다. 임신 손실은 재태 28주까지로 정의하였고 임신 예후는 후향적으로 의무기록지를 분석하였다. 전 대상 환자는 동일 시술자가 재태 9~12주 사이에 시술하였으며 두 방법의 융모막 검사 중 보다 안전하고 효율적인 방법을 알고자 임신손실율, 일차 시술성공율, 합병증 등을 비교 하였다. 결과 : 표본 채취 기구의 1회 삽입 후 표본을 얻는데 경자궁경부 방법에서는 88%, 경복식 방법에서는 94.4%의 성공률을 보였다(P<0.05). 시술 후 염색체 검사상 정상이면서 임신 28주까지의 태아손실율은 경자궁경부방법이 경복식방법보다 높았다(4.9%, 3.5%). 시술 후 합병증으로는 융모막하혈종, 양수유출, 질출혈, 융모양막염등이 나타났고, 그 빈도는 경자궁방법이 경복식보다 높았다(3.9%, 2.8%). 결론 : 임신 제 1기에 유전 및 염색체 질환을 진단하는데 경복식 융모막 검사가 경자궁경부방법에 비해 시술이 용이하고 동등한 안전성을 갖는 검사로써 향후 널리 시술될 수 있으리라 생각된다. Objectives : Our purpose was to compare the safety and efficacy of transcervical and transabdominal chorionic villus sampling.Methods : From January 1991 through June 1998, we retrospectively compared transcervical and transabdominal chorionic villus sampling in 633 women. Both CVS procedures were performed between 9 and 12 weeks of gestation by single operator. Both groups were followed to determine the outcome of pregnancy and the rate of spontaneous fetal loss after chorionic villus sampling.Result : Sampling was successful after a single insertion of the sampling instrument in 94.4 percent of the transabdominal procedures and 88 percent of the transcervical procedures(p〈0.05). Among the women with chromosomally normal pregnancies, the rate of spontaneous fetal loss through 28 weeks of pregnancy was 4.9 percent in the transcervical-sampling group and 3.5 percent in the transabdominal-sampling group. The frequency of symptoms and complication after transcervical procedures was slightly higher than transabdominal procedures (3.9%, 2.8%).Conclusion : Transabdominal and transcervical chorionic villus sampling appear to be equally safe procedures for first-trimester diagnosis of fetal abnormalities.
