46 실험결과에대한종합적고찰 1. Nox4 발현조절과 anoikis 조절기전규명 : Nox4 의발현이 EGFR 에의해조절되며, EGFR 의 발현과활성또한 Nox4 에의해조절됨을확인하였으며, Nox4 나 EGFR 을 knock-down 했을때 anoikis 가증가함을확인함. 2. Skp2와 CDCP1의발현조절과 anoikis 조절기전규명 : 새로운 anoikis regulator로예상된 Skp2와 CDCP1의발현이 EGFR과 Her-2에의해조절됨을확인하였으며, 특히 CDCP1의경우 anoikis resistance 뿐만아니라 cell adhesion, anchorage-independent cell growth 에중요함을확인함. 3. 부착성에따른 energy metabolism 차이규명 : suspended cancer cell이 suspended normal cell보다세포내 ATP 양과 glucose uptake 양의감소가억제됨을확인함으로써, suspended cancer cell이 energy metabolism을조절하여 anoikis resistance을가지는것으로예상됨. 4. anoikis resistant cancer cell line 수립 : mouse bladder cancer cell line인 MBT-2 cell을 syngeneic mouse (C3H-HE mouse) 의 bladder에 injection 하여 kidney나 lung에전이된암조직을추출하여 primary culture하여세포주를만들고, 이렇게만들어진세포주를다시두번더반복하여단계적인 metastasis model cell line을구축함. 실험결과에대한종합적고찰
