초록

고농도 포도당이 뼈모세포와 치주인대세포의 세포자멸사에 미치는 영향과 그 경로를 알아보기 위하여 뼈모세포주인 MC3T3-E1 (E1) 세포와 사람 치주인대로부터 일차배양을 통해 얻은 치주인대세포를 1,000 mg/L 농도의 포도당이 포함된 배양액 (대조군)과 4,500 mg/L 농도의 포도당이 포함된 배양액 (실험군)으로 나누어 24시간과 48시간 배양하였다. 그 후, ELISA assay를 통해 p38 MAPK와 caspase-3의 발현을 평가하고 Western blot을 통해 JNK-1과 ERK-1의 발현을 평가하여 다음과 같은 결론을 얻었다. 1. 뼈모세포와 치주인대세포 모두 대조군에 비해 실험군에서 caspase-3와 p38 MAPK 발현이 증가하였다. 2. 실험군에서의 caspase-3와 p38 MAPK 발현은 뼈모세포에 비해 치주인대세포에서 더욱 크게 증가하였다. 3. 뼈모세포와 치주인대세포 모두 대조군에 비해 실험군에서 JNK-1 발현이 증가하였다. 4. 뼈모세포와 치주인대세포 모두 ERK-1 발현에는 변화가 없었다. 이상의 결과로 보아, 고혈당 조건에 의해 뼈모세포와 치주인대세포의 세포자멸사가 증가하며, 치주인대세포가 고혈당 조건에 더욱 민감하게 반응하여 세포자멸사가 크게 증가하는 것으로 생각된다. 또한 이들 세포의 세포자멸사 과정은 p38 MAPK와 JNK-1 경로가 관여하며 ERK-1 경로는 관여하지 않는 것으로 추정된다.

This experiment was designed to clarify the effect of extracellular glucose on the osteoblasts and periodontal ligament cells. The cells were incubated for 24 and 48 hours with ${\alpha}$-MEM including 1,000 mg/L (control group) and 4,500 mg/L (experimental group) of glucose. Then, the expressions of caspase-3, p38 MAPK, JNK-1, and ERK-1 were examined using Elisa assay and Western blot. The results were as follows: 1. The expression of caspase-3 and p38 MAPK was increased by the high extracellular glucose in both cells. 2. The expression of caspase-3 and p38 MAPK was increased greatly in the periodontal ligament cells than the E1 cells by the high extracellular glucose. 3. The expression of JNK-1 was increased by the high extracellular glucose in both cells. 4. The expression of ERK-1 was not changed by the high extracellular glucose in both cells. These results suggest that extracellular glucose at high concentrations may inhibit the periodontal regeneration process increasing cellular apoptosis. And p38 MAPK and JNK-1 pathway may be the most responsible intracellular pathway rather than ERK-1.
