A promising effect of zerumbone with improved anti-tumor-promoting inflammation activity of miR-34a in colorectal cancer cell lines.
    Molecular biology reports, 2021, Volume: 48, Issue:1

    Cross-talk among inflammation and colorectal cancer cells is chiefly reported through a complex of cytokines, chemokines, and growth factors. MicroRNA performs strategic roles in controlling a variety of signaling cascades. miR-34a is known as a master regulator of tumor suppression. Combined application of different miRNA-based agents and chemotherapeutic drugs has been used to augment drug sensitivity and may reinforce the antitumor effect. A lot of studies specify a substantial increase in the effectiveness of combination therapies. The anti-inflammatory activity of Zerumbone (ZER) was investigated in many cancers. In this study the level of the inflammatory cytokines including CXCL-12 (SDF-1), CCL-2 (MCP-1), TGF-β and IL-33 has been measured in pmiR-34a-5p transfected and pmiR-34a-5p +ZER treated CRC cell lines (HCT-116 and SW48) by QRT-PCR and ELISA methods, respectively. The results showed that miR-34a could significantly inhibit cytokine expression in both cell lines for 48 and 72 h except SDF-1 which no inhibition was observed in SW48 cells. ZER suppressed SDF-1 for all three time points in both cell lines, while in SW48 cells IL-33 and TGF-β were inhibited in 72 h and in HCT-116 cells MCP-1 diminished for only 24 h and TGF-β diminished for all three times. Combination of both miR-34a and ZER suppressed TGF-β, SDF-1 and MCP-1 in HCT-116 cells in all time points while in SW48 cells, suppression of most cytokines was observed in 48 and 72 h. Furthermore Colony formation assay and scratch test were employed to detect changes of proliferation and migration in CRC transfected and treated cells. Generally, we found that miR-34a could considerably decrease the expression of inflammatory cytokines and the combination of ZER+ miR-34 boosted this effect. Moreover the migration and proliferation decreased in treated and transfected cells and this reduction was more severe in miR-34a +ZER treatment. It is important to note that in the case of cell resistance to each of these therapeutic agents, inhibition of cytokines can be compensated by another one.

Zerumbone Suppresses Human Colorectal Cancer Invasion and Metastasis via Modulation of FAk/PI3k/NFκB-uPA Pathway.
    Nutrition and cancer, 2019, Volume: 71, Issue:1

    The current study explored the basic molecular mechanisms of zerumbone (ZER), an herbal compound, in inhibiting the migration and invasion of colorectal cancer (CRC) cells in vitro. Two types of CRC cells, namely HCT-116 and SW48, were treated with various concentrations of ZER (8, 16, and 24 µM) for 24, 48, and 72 h, respectively. In vitro assays were performed to determine alterations in proliferation ability, mRNA expression and protein levels, and migration and invasion potential of CRC cells. An SYBR Green-based quantitative polymerase chain reaction (PCR) was utilized to detect the gene expression of focal adhesion kinase (FAK), nuclear factor (NF)-κB, and urokinase-type plasminogen activator (uPA) followed by the evaluation of the level of proteins by western blotting. Migration and invasion potentials of HCT-116 and SW48 cells treated by ZER were examined using migration and invasion assay kits, respectively. We compared the results of all experiments with control groups, including FAK inhibitor, ZER + FAK inhibitor-treated cells, NF-β inhibitor, ZER + NF-β inhibitor, and untreated cells. The data in the present study suggest that ZER may exert its antimetastatic effects through inhibition of FAk/PI3k/NF-κB-uPA signaling pathway, thereby possibly representing a novel class of FAK inhibitors.

Zerumbone, a Cyclic Sesquiterpene from Zingiber zerumbet Induces Apoptosis, Cell Cycle Arrest, and Antimigratory Effects in SW480 Colorectal Cancer Cells.
    Journal of agricultural and food chemistry, 2018, Jan-24, Volume: 66, Issue:3

    Zerumbone isolated from the rhizomes of Zingiber zerumbet was investigated for the mechanisms by which it exhibits antiproliferative activity in colorectal cancer cells (SW480). The results indicated that the zerumbone suppressed cell growth and enhanced cell apoptosis. Exposure to zerumbone induced generation of reactive oxygen species, reduced the cellular antioxidant status, decreased mitochondrial membrane potential, and activated caspase 3, caspase 8, and caspase 9 (p < 0.001). It was also found that there was a decrease in the expression of Bcl 2 and elevation of Bax (p < 0.001) on exposure to zerumbone. Furthermore, treatment with 50, 75, and 100 μM zerumbone resulted in cell cycle arrest at the G2/M phase with a value of 17.2 ± 0.1, 19.63 ± 0.25, and 26.66 ± 0.25, respectively, and also distorted the microfilament network and effectively inhibited cellular migration.

Zerumbone inhibits epithelial-mesenchymal transition and cancer stem cells properties by inhibiting the β-catenin pathway through miR-200c.
    Journal of cellular physiology, 2018, Volume: 233, Issue:12

    Colorectal cancer (CRC) is one of the most lethal and rampant human malignancies in the world. Zerumbone, a sesquiterpene isolated from subtropical ginger, has been found to exhibit an antitumor effect in various cancer types. However, the effect of Zerumbone on the biological properties of CRC, including epithelial-mesenchymal transition (EMT) and cancer stem cells (CSCs) has not been fully elucidated. Here, we investigated the inhibitory action of Zerumbone on the EMT process, CSC markers, and the β-catenin signaling pathway in the presence or absence of miR-200c. The effect of Zerumbone on HCT-116 and SW-48 cells viability was examined by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay. The effects of Zerumbone on EMT-related genes, CSCs markers, cell migration, invasion, sphere-forming, and β-catenin signaling pathway were explored. To evaluate the role of miR-200c in anticancer effects by Zerumbone, miR-200c was downregulated by LNA-anti-miR-200c. Zerumbone significantly inhibited cell viability, migration, invasion, and sphere-forming potential in HCT-116 and SW-48 cell lines. Zerumbone significantly suppressed the EMT and CSC properties as well as downregulated the β-catenin. Silencing of miR200c reduced the inhibitory effects of Zerumbone on EMT and CSCs in CRC cells. These data indicated that Zerumbone may be a promising candidate for reducing the risk of CRC progression by suppressing the β-catenin pathway via miR-200c.

Zerumbone increases oxidative stress in a thiol-dependent ROS-independent manner to increase DNA damage and sensitize colorectal cancer cells to radiation.
    Cancer medicine, 2015, Volume: 4, Issue:2

    Locally advanced rectal cancers are treated with neoadjuvant chemoradiation therapy followed by surgery. In a minority (~20%) of patients, no tumor is present at the time of surgery; these patients with a complete pathologic response (pathCR) to neoadjuvant therapy have better treatment outcomes. Unfortunately, the inherent radioresistance of colorectal cancer (CRC) cells dictates that the majority of patients do not achieve a pathCR. Efforts to improve these odds have fueled the search for novel, relatively less-toxic radiosensitizers with distinct molecular mechanism(s) and broad-spectrum anticancer activities. Here, we use zerumbone, a sesquiterpene from the edible ginger (Zingiber zerumbet Smith), to enhance radiosensitivity of CRC cells. Short exposure to zerumbone (7 h) profoundly sensitized CRC cells, independent of their p53 or k-RAS status. Zerumbone enhanced radiation-induced cell cycle arrest (G2/M), increased radiation-induced apoptosis, but induced little apoptosis by itself. Zerumbone significantly enhanced radiation-induced DNA damage, as evident by delayed resolution of post-irradiation nuclear γH2AX foci, whereas zerumbone treatment alone did not induce γH2AX foci formation. Zerumbone pretreatment inhibited radiation-induced nuclear expression of DNA repair proteins ataxia-telangiectasia mutated (ATM) and DNA-PKcs. Interestingly, zerumbone-mediated radiosensitization did not involve reactive oxygen species (ROS), but was mediated through depletion of cellular glutathione (GSH). Ability of only thiol-based antioxidants to abrogate zerumbone-mediated radiosensitization further corroborated this hypothesis. The α,β-unsaturated carbonyl group in zerumbone was found to be essential for its bioactivity as zerumbone analog α-Humulene that lacks this functional group, could neither radiosensitize CRC cells, nor deplete cellular GSH. Our studies elucidate novel mechanism(s) of zerumbone's ability to enhance CRC radiosensitivity.
