Abstract A01: Trichodermin induces G1/S cell cycle arrest in ovarian cancer cells

Ovarian cancer is a major health concern for women as it is prominent among gynecologic cancers. Trichodermin is a sesquiterpene isolated from Nalanthamala psidii and found to induce apoptosis in human chondrosarcoma cells. In this study, A2780/CP70 and OVCAR-3 ovarian cancer cell lines were treated with trichodermin to determine whether it had an anti-cancer effect. Our data presented that trichodermin reduced the viability of both ovarian cancer cells by inducing G1/S cell cycle arrest rather than apoptosis. The underlying mechanism might be that trichodermin down-regulated the expression of Cyclin D1 via inhibiting AhR and c-Myc expression. Therefore, trichodermin is promising in ovarian cancer treatment. Citation Format: Yi C. Chen, Ying Gao. Trichodermin induces G1/S cell cycle arrest in ovarian cancer cells. [abstract].
