Purpose: To investigate the anticancer effects of sparteine against human cervical cancer. Methods: Cell viability was determined by CCK8 assay, while 4′, 6-diamidino-2-phenylindole (DAPI) staining was used for determination of apoptosis. Cell cycle analysis was done with flow cytometry, while cell invasion was monitored using Transwell invasion assays. Protein expressions were determined using Western blotting. Results: The results revealed that sparteine inhibited the viability of cervical cancer cells with halfmaximal inhibitory concentration (IC50) ranging from 10 to 25 µM. Sparteine exerted more profound antiproliferative effects on DoTc2 cells, with IC50 of 10 µM. However, minimal cytotoxicity was observed in normal cervical cells, as evident from the IC50 of 80 µM. Sparteine triggered the generation of ROS and apoptotic cell death in DoTc2 cells. The induction of apoptosis was accompanied by upregulation of Bax expression and downregulation of Bcl-2 expression. Sparteine caused arrest of DoTc2 cells at the G0/G1 phase of the cell cycle, and suppressed the expressions of cyclin A and cyclin B1. Transwell assay data showed that sparteine decreased the invasion ability of DoTc2 cells. Sparteine also inhibited the phosphorylation of VGFR2 in a concentration-dependent manner. Conclusion: Sparteine exhibits significant anticancer activity and may prove beneficial in cervical cancer chemotherapy.

Previously, we found that desethylamiodarone (DEA) may have therapeutic potentiality in bladder cancer. In this study, we determined its effects on human cervical cancer cells (HeLa). Cell viability was evaluated by Muse Cell Count & Viability Assay; cell apoptosis was detected by Muse Annexin V & Dead Cell Assay. Cell cycle was flow cytometrically determined by Muse Cell Cycle Kit and the morphological changes of the cells were observed under a fluorescence microscope after Hoechst 33342 staining. The changes in the expression levels of apoptosis-related proteins in the HeLa cells were assessed by immunoblot. Our results showed that DEA significantly inhibited the proliferation and viability of HeLa cells and induced apoptosis in vitro in dose-dependent and also in cell cycle-dependent manner because DEA induced G0/G1 phase arrest in the HeLa cell line. We found that DEA treatment downregulated the expression of phospho-Akt and phospho-Bad. In addition, DEA could downregulate expression of Bcl-2, upregulate Bax, and induce cytochrome c release. Our results indicate that DEA might have significance as an anti-tumor agent against human cervical cancer.

In this study, silver nanoparticles (AgNPs) were synthesized using aqueous extract of Nepeta deflersiana plant. The prepared AgNPs (ND-AgNPs) were examined by ultraviolet-visible spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscope (SEM), and energy dispersive spectroscopy (EDX). The results obtained from various characterizations revealed that average size of synthesized AgNPs was 33 nm and in face-centered-cubic structure. The anticancer potential of ND-AgNPs was investigated against human cervical cancer cells (HeLa). The cytotoxic response was assessed by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT), neutral red uptake (NRU) assays, and morphological changes. Further, the influence of cytotoxic concentrations of ND-AgNPs on oxidative stress markers, reactive oxygen species (ROS) generation, mitochondrial membrane potential (MMP), cell cycle arrest and apoptosis/necrosis was studied. The cytotoxic response observed was in a concentration-dependent manner. Furthermore, the results also showed a significant increase in ROS and lipid peroxidation (LPO), along with a decrease in MMP and glutathione (GSH) levels. The cell cycle analysis and apoptosis/necrosis assay data exhibited ND-AgNPs-induced SubG1 arrest and apoptotic/necrotic cell death. The biosynthesized AgNPs-induced cell death in HeLA cells suggested the anticancer potential of ND-AgNPs. Therefore, they may be used to treat the cervical cancer cells.

Zingiber ottensii (ZO) is a local plant in Thailand and has been used as a Thai traditional therapy for many conditions. ZO has been reported to exhibit many pharmacological effects, including anti-cancer activity. Nevertheless, its anti-cancer effects explored at the signaling level have not been elucidated in cervical cancer, which is one of the leading causes of fatality in females. We discovered that the essential oil of ZO significantly increased the apoptosis of human cervical cancer cells (HeLa) after 24 h of treatment in a concentration-dependent manner. Our data also clearly demonstrated that ZO essential oil reduced IL-6 levels in the culture supernatants of the cancer cells. Moreover, Western blot analysis clearly verified that cells were induced to undergo apoptotic death via caspase activation upon treatment with ZO essential oil. Interestingly, immunofluorescence studies and Western blot analyses showed that ZO essential oil suppressed epidermal growth factor (EGF)-induced pAkt and pERK1/2 signaling pathway activation. Together, our study demonstrates that ZO essential oil can reduce the proliferation and survival signaling of HeLa cervical cancer cells. Our study provides convincing data that ZO essential oil suppresses the growth and survival of cervical cancer cells, and it may be a potential choice for developing an anti-cancer agent for treating certain cervical cancers.

We investigate induction of apoptosis by xanthohumol on Ca Ski cervical cancer cell line. Xanthohumol is a prenylated chalcone naturally found in hop plants, previously reported to be an effective anticancer agent in various cancer cell lines. The present study showed that xanthohumol was effective to inhibit proliferation of Ca Ski cells based on IC50values using sulforhodamine B (SRB) assay. Furthermore, cellular and nuclear morphological changes were observed in the cells using phase contrast microscopy and Hoechst/PI fluorescent staining. In addition, 48-hour long treatment with xanthohumol triggered externalization of phosphatidylserine, changes in mitochondrial membrane potential, and DNA fragmentation in the cells. Additionally, xanthohumol mediated S phase arrest in cell cycle analysis and increased activities of caspase-3, caspase-8, and caspase-9. On the other hand, Western blot analysis showed that the expression levels of cleaved PARP, p53, and AIF increased, while Bcl-2 and XIAP decreased in a dose-dependent manner. Taken together, these findings indicate that xanthohumol-induced cell death might involve intrinsic and extrinsic apoptotic pathways, as well as downregulation of XIAP, upregulation of p53 proteins, and S phase cell cycle arrest in Ca Ski cervical cancer cells. This work suggests that xanthohumol is a potent chemotherapeutic candidate for cervical cancer.

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>
