G1 Cell Cycle Arrest

Ovarian cancer is a fatal gynecological cancer because of a lack of early diagnosis, which often relapses as chemoresistant. Trichodermin, a trichothecene first isolated from Trichoderma viride, is an inhibitor of eukaryotic protein synthesis. However, whether trichodermin is able to suppress ovarian cancer or not was unclear. In this study, trichodermin (0.5 µM or greater) significantly decreased the proliferation of two ovarian cancer cell lines A2780/CP70 and OVCAR-3. Normal ovarian IOSE 346 cells were much less susceptible to trichodermin than the cancer cell lines. Trichodermin predominantly inhibited ovarian cancer cells by inducing G0/G1 cell cycle arrest rather than apoptosis. Trichodermin decreased the expression of cyclin D1, CDK4, CDK2, retinoblastoma protein, Cdc25A, and c-Myc but showed little effect on the expression of p21Waf1/Cip1, p27Kip1, or p16Ink4a. c-Myc was a key target of trichodermin. Trichodermin regulated the expression of Cdc25A and its downstream proteins via c-Myc. Overexpression of c-Myc attenuated trichodermin’s anti-ovarian cancer activity. In addition, trichodermin decelerated tumor growth in BALB/c nude mice, proving its effectiveness in vivo. These findings suggested that trichodermin has the potential to contribute to the treatment of ovarian cancer.

G1 Cell Cycle Arrest

Barringtonia asiatica, is traditionally used as a medicinal plant in the Philippines; unfortunately, there is limited evidence supporting its anticancer capability. Thus, our study investigated the cytotoxic effect of B. asiatica seed extract against ovarian carcinoma A2780 (ECACC 93112519) and Saccharomyces cerevisiae as a cancer model organism. Seeds of B. asiatica were freeze-dried and extracted with methanol. The seed extract was investigated for its effect on the cell cycle in S. cerevisiae by utilizing yeast budding experiment and imaging flow cytometry. Its cytotoxicity activity was also tested as well as a live/dead assay was conducted against ovarian cancer cells. Findings revealed the anticancer activity of B. asiatica and its capability to induce G1 cell cycle arrest in S. cerevisiae. Thus, B. asiatica seeds may serve as a potential source of natural compounds towards anticancer drug discovery.
