<p class="Abstract">The main objective of the present study was to investigate the anti-tumor activity of corosolic acid in CaSki human cervical cancer cells. Fluorescence and phase contrast microscopic techniques were used to study the effect of the compound on cellular morphology and apoptosis. Results revealed that corosolic acid exerted potent, dose- and time-dependent growth inhibitory effects in CaSki cell proliferation. Cells got detached from one another making clusters of small number of cells floating in the medium. After the cells were treated with 10, 50 and 100 µM concentrations of corosolic acid, cells began to emit orange red fluorescence more heavily at the centre of cells indicating apoptosis. Corosolic acid also induced G2/M cell cycle arrest in a dose-dependent manner. Increasing doses of corosolic acid treatment to these cells resulted in significant and dose-dependent down-regulation of PI3K and Akt protein expressions.</p><p><strong>Video Clip</strong></p><p><a href="https://youtube.com/v/N4EivZECRZE">Western blot assay</a>: 2 min 1 sec  </p>

Baicalein, a flavonoid derived from the root of Scutellaria baicalensis, has been reported to possess multiple pharmacological activities, such as anticancer and anti-inflammatory properties. This study investigated the effect of baicalein in cervical cancer cells. Cell growth curve and MTT assay were performed and revealed that baicalein inhibited the proliferation of SiHa and HeLa cells in a dose-dependent manner. We further found that baicalein arrested the cell cycle of SiHa and HeLa cells at the G0/G1 phase by suppressing the expression of cyclin D1 through the downregulation of phosphorylated protein kinase B (p-AKT) and phosphorylated glycogen synthase kinase 3β (p-GSK3β) according to FACS assays and Western blotting. Moreover, when CHIR-99021, a GSK3β inhibitor, was added to baicalein-treated SiHa cells, the expression of cyclin D1 was recovered, and cell proliferation was promoted. In conclusion, these data indicated that baicalein suspended the cell cycle at the G0/G1 phase via the downregulation of cyclin D1 through the AKT‐GSK3β signaling pathway and further inhibited the proliferation of SiHa and HeLa cervical cancer cells.

<p class="Abstract">The present study was aimed at to demonstrate the antitumor effects of syringin in HeLa human cervical cancer cells. Its effects on apoptosis, cell cycle phase distribution as well as on cell migration were also examined. The effect on cell proliferation was evaluated by MTT assay, while as effects on colony formation were assessed using clonogenic assay. Syringin inhibited cancer cell growth in HeLa cells in a time-dependent as well as in a concentration-dependent manner. Syringin also led to inhibition of colony formation efficacy with complete suppression at 100 µM drug dose. Syringin could induce G2/M cell cycle arrest along with slight sub-G1 cell cycle arrest. HeLa cells began to emit red fluorescence as the dose of syringin increased from 0 µM in vehicle control to 100 µM. Syringin also inhibited cell migration in a dose-dependent manner with 100 µM dose of syringin leading to 100% inhibition of cell migration.</p><p> </p>

Buformin is a commonly used hypoglycemic agent, and numerous studies have shown that buformin has potent antitumor effects in several malignancies. In this study, we aimed to assess the cytotoxic effect of buformin combined with ionizing radiation (IR) on two human cervical cancer cell lines (Hela and Siha). Cytotoxicity was detected by colony formation assays; impacts on the cell cycle and apoptosis were detected by flow cytometric analyses. Changes in histone H2AX (γ-H2AX) phosphorylation and impacts on the AMPK/S6 pathway were also explored. Our data show that the combination of buformin and IR had a much stronger antiproliferative effect and resulted in more apoptosis than did buformin or IR alone. Combination treatment with a low dose of buformin (10 µM) and IR (4 Gy) caused G2/M-phase cell cycle arrest. Consistent with these findings, Western blotting showed that the combination of buformin and IR activated AMPK and suppressed S6. In addition, delayed disappearance of γ-H2AX was detected by immunofluorescence in cervical cancer cells treated with buformin plus IR. Taken together, the data indicate that the combination of a low concentration of buformin and IR increases the radiosensitivity of cervical cancer cells via cell cycle arrest and inhibition of DNA repair. Based on these results, we strongly support the use of buformin as an effective agent for improving IR treatment efficiency in the context of cervical cancer. Impact statement Our idea originated in the thought of discovering new effects of old drugs. Although this study is a basic research, it is very close to clinical treatment. Flow cytometry and immunofluorescence were used to verify that buformin increases radiosensitivity. We aimed to address one of the thorniest problems in treatment process. Based on discovering new effects of old drugs, it is feasible to use buformin as an anticancer drug in clinical application. This will provide new ideas for clinical treatment.
