体外研究
(In Vitro)

Exposure of the COLO205 cells to Cucurbitacin I significantly decreases cell viability. The anticancer activity of Cucurbitacin I is accomplished by downregulating p-STAT3 and MMP-9 expression[1]. PE-induced cell enlargement and upregulation of ANF and β-MHC are significantly suppressed by pretreatment of the cardiomyocytes with Cucurbitacin I. Notably, Cucurbitacin I also impaires connective tissue growth factor (CTGF) and MAPK signaling, pro-hypertrophic factors, as well as TGF-β/Smad signaling, the important contributing factors to fibrosis[2]. Incubation of the Seax cell line with the Jak/Stat3 inhibitor Cucurbitacin I result in a time- and concentration-dependent decrease of P-Stat3 and Stat3. In freshly isolated Sz cells (n=3), Cucurbitacin I induces a concentration-dependent decrease in Stat3 expression whereas P-Stat3 is undetectable. Finally, incubation of freshly isolated Sz cells (n=4) with 30 μM Cucurbitacin I for 6 hours induces apoptosis in the large majority (73-91%) of tumor cells[3].

体内研究
(In Vivo)

No major side effects are noted throughout the study. It is shown that average tumor volumes at the end of the study are as follows: control, 616 mm3 (±130); CQ, 580 mm3 (±107); Cucurbitacin I, 346mm3 (±79); and combination, 220mm3 (±62). The differences in tumor volume between the Cucurbitacin I and control, combination and control, and combination and Cucurbitacin I arms are significant. Furthermore, combination-treated tumors exhibit a significantly lower average tumor weight at study termination than the control. Moreover, there was no effect on the body weights of mice[4].

Animal Administration
[4]

Mice[4]
BALB/c nude (nu/nu) female mice are used. U251 cells (5×106 cells in 50 μL of serum-free DMEM) are inoculated subcutaneously into the right flank of 5-week-old female mice after acclimatization for a week. Tumor growth is measured daily with calipers. When the tumors reach a mean volume of 90-120 mm3, animals are randomized into groups. In the first experiment, 16 mice are randomly assigned to Cucurbitacin I (1 mg/kg/day in 20% DMSO in PBS) or drug vehicle control (20% DMSO in PBS) and dosed intraperitoneally with 100 μL of vehicle or drug once daily for 18 days, whereas, in the second, 20 mice are assigned to four groups. Control animals receive 20% DMSO in PBS vehicle, whereas treated animals are injected with Cucurbitacin I (1 mg/kg/day) in 20% DMSO in PBS, CQ (25 mg/kg/day) in 20% DMSO in PBS, and Cucurbitacin I (1 mg/kg/day) plus CQ (25 mg/kg/day) in 20% DMSO in PBS and dosed intraperitoneally with 100 μL of vehicle or drug once daily for 15 days[4].

生物活性

Cucurbitacin B belongs to a class of highly oxidized tetracyclic triterpenoids; could repress cancer cell progression. IC50 value: Target: anticancer natural compound in vitro: Cucurbitacin-B inhibited growth and modulated expression of cell-cycle regulators in SHSY5Y cells. At the molecular level, we found that Cucurbitacin-B inhibited AKT signaling activation through up-regulation of PTEN [1]. CuB induced apoptosis of A549 cells in a -concentration-dependent manner, as determined by fluorescence microscopy, flow cytometry and transmission electron microscopy. CuB dose-dependently inhibited lung cancer cell proliferation, with cell cycle inhibition and cyclin B1 downregulation. Apoptosis induced by CuB was shown to be associated with cytochrome c release, B-cell lymphoma 2 downregulation and signal transducer and activator of transcription 3 pathway inhibition [2]. CuB inhibited ITGA6 and ITGB4 (integrin α6 and integrin β4), which are overexpressed in breast cancer. Furthermore, CuB also induced the expression of major ITGB1and ITGB3, which are known to cause integrin-mediated cell death [3]. Cuc B treatment caused DNA double-strand breaks (DSBs) without affecting the signal transducer and activator of transcription 3 (STAT3), the potential molecular target for Cuc B. Cuc B triggers ATM-activated Chk1-Cdc25C-Cdk1, which could be reversed by both ATM siRNA and Chk1 siRNA. Cuc B also triggers ATM-activated p53-14-3-3-σ pathways, which could be reversed by ATM siRNA [4]. in vivo: Efficacy of CuB was tested in vivo using two different orthotopic models of breast cancer. MDA-MB-231 and 4T-1 cells were injected orthotopically in the mammary fat pad of female athymic nude mice or BALB/c mice respectively. Our results showed that CuB administration inhibited MDA-MB-231 orthotopic tumors by 55%, and 4T-1 tumors by 40%. The 4T-1 cells represent stage IV breast cancer and form very aggressive tumors [3].

体外研究
(In Vitro)

To explore the antitumor activity of Cucurbitacin E (CuE) against colorectal cancer (CRC) cells, an in vitro study is initiated in which each of the CRC cell lines is exposed to increasing doses of Cucurbitacin E (0, 2.5, 5, and 7.5 μM) over a period of 24 h. The proliferation of the Cucurbitacin E-treated cancer cells is then measured using the MTT method. Cucurbitacin E is shown to induce morphological changes in the primary colon cancer cells. Microscopic observation showed that following exposure to Cucurbitacin E (5 μM) between 6 and 24 h, the primary colon cancer cells underwent a remarkable change in morphology. Cucurbitacin E inhibits tumor growth by arresting the cell cycle in the G2/M phase via GADD45γ gene expression and the blockage of cyclin B1/CDC2 complex in primary CRC cells[1].

(In Vivo)

A high fat diet mice model of metabolic syndrome (HFD-MetS) is developed to assess the role of Cucurbitacin E (CuE) on body weight and fat tissue biology. Significant decrease in body weights of HFD-MetS mice treated with Cucurbitacin E (0.5mg/kg) are found as compared to HFD-MetS mice treated with vehicle alone. Cucurbitacin E treatment reduces all fat pads weights in HFD-MetS mice. 55% reduction is observed in total fat in mice, after treatment with Cucurbitacin E in comparison to HFD-MetS mice. Abdominal obesity is strongly associated with metabolic syndrome. Central obesity is reduced to 50% after Cucurbitacin E treatment as compared to HFD MetS mice, elucidating the effectiveness of Cucurbitacin E in targeting MetS[2].

Cell Assay
[1]

The colorectal cancer (CRC) cells are seeded into 96-well culture plates at 5000 cells/well. The cells are treated with 0, 2.5, 5, and 7.5 μM Cucurbitacin E for 1-3 days. MTT dye (1 mg/mL) is added to each well for at least 4 h of treatment. The reaction is stopped by the addition of DMSO, and optical density is measured at 540 nm on a multi-well plate reader. Background absorbance of the medium in the absence of cells is subtracted. All samples are assayed in triplicate, and the mean for each experiment is calculated. Results are expressed as a percentage of control, which is considered as 100%. Each assay is carried out in triplicate, and the results are expressed as the mean[1].

Animal Administration
[2]

Mice[2]
C57BL/6 male mice are used. The mice are designated as metabolic syndrome mice (HFD-MetS-mice). Briefly, the mice are randomly assigned into two groups according to their diet for 8 weeks (n = 10-12): high fat diet group (HFD) (60% fat, 20% carbohydrate, 20% protein) or the matched low fat, standard diet group (SD) (10% fat, 70% carbohydrate, 20% protein). After eight weeks on high fat diet, the mice with significant obese phenotype and fasting blood glucose levels ≥126 mg/dL are considered MetS mice. The MetS mice are continued on the HFD throughout the study. The MetS mice are then randomly divided into three additional groups, according to the treatment administered by oral gavage for 10 weeks (n=10-12): a low dose 0.25 mg/kg/day of Cucurbitacin E designated as HFD+Cucurbitacin E (L) or high dose 0.5 mg/kg/day of Cucurbitacin E, designated as HFD+Cucurbitacin E (H) or 50 mg/kg/day Orlistat (HFD+Orlistat). Animals on SD are administered 0.5% CMC by oral gavage[2].
