Epothilone은 현재 항암제로 사용되고 있는 탁솔이나 탁소텔 등과 같이 Microtubule(미세소관)을 안정화시켜 세포분열을 억제함으로써 암 세포의 증식을 막아 줄 수 있는 물질이다.

혈관 평활근세포(vascular smooth muscle cell, VSMC)의 증식은 동맥경화증의 주요 원인으로 알려져 있다. 따라서 본 논문에서는 Epothilone의 과도한 세포증식 억제 가능성을 이용하여 Human colon cancer SW620 세포와 혈관평활근세포(VSMC) 증식에 대한 억제효과와 작용 기작을 규명했다.

Epothilone B와 D를 처리한 군의 경우 대장암 세포를 농도의존적으로 저해하였으며 epothilone들에 의해 cell cycle이 arrest(G₂/M)되어 apoptosis가 일어났다. epothilone B와 D는 IkB kinase (IKKα and IKKβ)를 통해 IkB degradation을 유발시켜 NF-κB를 활성화 시켰으며 결과적으로 nucleus로 p50과 p65의 translocation을 일으켰다. 또한 epothilone B와 D은 β-tubulin polymerization과 p50/β-tubulin complex의 형성도 증가시켰다. IKK 저해제인 Sodium salicylic acid을 첨가하거나 IKKα 변이주를 사용하였을 때에 β-tubulin polymerization은 증가되지 않았으나 NF-κB dependent apoptotic cell death regulatory genes인 Bax, p53, caspase-3는 증가시켰다. Caspase-3 inhibitor, 사용 시 epothilone B-induced cell death와 NF-kB 활성을 감소 시켰다.

이상의 결과를 통해 NF-κB/IKK 신호가 tubulin polymerization에 비의존적으로 epothilone에 의해 유도되는 대장암세포 SW620 사멸에 중요한 역할을 담당하는 것을 알 수 있었다.

흰쥐경동맥 손상모델에서 Epothilone B와 D의 신생내막형성 억제효과와 흰쥐경동맥 평활근세포(VSMC)의 증식을 촉진 시키는 성장인자의 변화도 조사 하였다. 혈소판유래 성장인자인 PDGF-BB처리 시 apoptosis가 유도되지 않았으나, EPOs를 첨가한 실험결과 epothilone B와 epothilone D는 유의적으로 VSMC의 세포사멸을 유도하였으며 전형적인 세포사멸 염색사의 형태적 변화와 함께 세포의 원형화와 플레이트로부터 탈착이 관찰 되었다. EPOs 처리군의 경우 cell cycle이 arrest(G0/G₁)되어 apoptosis가 일어나는 것을 알 수 있었다. 또한 EPOs는 세포핵내의 p53발현을 증가시켰으며 이들 p53의 전좌(translocation)가 세포사멸의 주요한 요인임을 확인 하였다. 신호전달 연구를 통해 epothilone B와 D가 p53의 발현과 축적을 유도하였으며 p53조절 caspase-3와 Bax가 활성화 되는 것을 알 수 있었다. 이러한 현상은 Paclitaxel을 양성대조군으로 사용한 rat carotid artery ballooninjury model의 동물실험을 통해 epothilone B, D, 그리고 Paclitaxel 투여로 신생내막형성이 유의적으로 억제되는 것을 확인하였다. 이상의 결과를 통해 epothilones의 신생내막형성억제 효과는 EPOs에 의해 활성화된 p53-dependent caspase-3 경로를 경유한 VSMC의 세포사멸에 기인함을 알 수 있었다.
