Cucurbitacin D (CuD), isolated from plants from the Cucurbitaceae family, is a potential antitumour agent since it inhibits proliferation, migration and metastasis of cancer cells. Despite CuD antitumour activity in cancer cells, the effects of CuD on gastric cancer cell lines remain unclear. The present study aimed to investigate the effects of CuD on gastric cancer cell growth and death. Human gastric cancer cell lines (AGS, SNU1 and Hs746T) were cultured and treated with different concentrations of CuD (0, 0.25, 0.5, 1 and 2 µM). Cell proliferation was assessed using Cell Counting Kit‑8 assay. Oxidative stress was evaluated by generation of reactive oxygen species (ROS). Cell apoptosis was assessed by terminal deoxynucleotidyl transferase 2’‑deoxyuridine‑5’‑triphosphate nick‑end labelling (TUNEL) staining. Levels of intracellular Ca2+ and adenosine triphosphate (ATP) were also assessed. In the present study, CuD effectively inhibited cell proliferation, triggered ROS generation and induced apoptosis in gastric cancer cells (AGS, SNU1 and Hs746T). Treatment with CuD increased intracellular Ca2+ and ATP levels. CuD also stimulated the expression of inducible nitric oxide synthase (iNOS), which augmented nitric oxide production. In addition, CuD activated the mitochondrial apoptosis pathway, which increased the expression of Bax and the release of cleaved caspace‑9 (C‑caspase‑9) and cytochrome c, decreased the expression of B‑cell lymphoma 2 (Bcl‑2). The mechanism of action of CuD involved the regulation of the protein kinase B/mechanistic target of rapamycin (Akt/mTOR) pathway. We confirmed the effects of CuD on gastric tumours via an in vivo xenograft gastric tumour model. In conclusion, CuD inhibited Akt and activated the iNOS pathway, leading to higher ROS and nitric oxide production, which accelerated gastric cancer cell apoptosis.

In this study, we for the first time, investigated the potential anti-cancer effects of a novel analogue of cucurbitacin (Cucurbitacin D) against cervical cancer in vitro and in vivo. Cucurbitacin D inhibited viability and growth of cervical cancer cells (CaSki and SiHa) in a dose-dependent manner. IC50 of Cucurbitacin D was recorded at 400 nM and 250 nM in CaSki and SiHa cells, respectively. Induction of apoptosis was observed in Cucurbitacin D treated cervical cancer cells as measured by enhanced Annexin V staining and cleavage in PARP protein. Cucurbitacin D treatment of cervical cancer cells arrested the cell cycle in G1/S phase, inhibited constitutive expression of E6, Cyclin D1, CDK4, pRb, and Rb and induced the protein levels of p21 and p27. Cucurbitacin D also inhibited phosphorylation of STAT3 at Ser727 and Tyr705 residues as well as its downstream target genes c-Myc, and MMP9. Cucurbitacin D enhanced the expression of tumor suppressor microRNAs (miR-145, miRNA-143, and miRNA34a) in cervical cancer cells. Cucurbitacin D treatment (1 mg/kg body weight) effectively inhibited growth of cervical cancer cells derived orthotopic xenograft tumors in athymic nude mice. These results demonstrate the potential therapeutic efficacy of Cucurbitacin D against cervical cancer.

We previously reported that the inflammasome inhibitor cucurbitacin D (CuD) induces apoptosis in human leukemia cell lines. In the present study, we investigated the effects of co-treatment with an additional Bcl-xL inhibitor, Z36. Treatment with Z36 induced cell death in leukemia cell lines, with MT-4 cells exhibiting the lowest sensitivity to Z36. Co-treatment of cells with Z36 and CuD resulted in a greater degree of cell death for Hut78 and Jurkat cells than treatment with CuD alone. In contrast, co-treatment of MT-4 cells with Z36 and CuD had a suppressive effect on cell death. The autophagy inhibitor 3-methyladenine (3-MA) suppressed the growth of leukemia cell lines HuT78, Jurkat, MT-1, and MT-4. CuD-induced cell death was enhanced by 3-MA in Jurkat cells, but inhibited in MT-4 cells. Western blotting results revealed cleavage of poly(ADP ribose) polymerase (PARP), supporting CuD-induced cell death; 3-MA enhanced CuD-Z36-induced PARP cleavage. Taken together, our results indicate that autophagy negatively regulates chemical-induced cell death of leukemia cells, and that controlling autophagy could be beneficial in the development of more effective chemotherapies against leukemia.
