In this study we investigated the effect of plant polyphenol PTK inhibitor genistein on subcutaneous human transplant ovarian cancer tumor of nude mice. All 30 cases of nude mice are used to establish subcutaneous xenograft models of human ovarian cancer, and divided into 4 groups: Control group (containing 0.04% DMSO of saline); Genistein group (containing 0.2 mg / kg and 0.4 mg/kg two concentrations, subcutaneous injection); Cisplatin group (4 mg/kg, i.v.); Genistein and Cisplatin combination group. The transplanted tumor growth and weight changes of nude mice in different groups on 7, 14, 21 and 28 days were observed and histopathological examined. The results showed that the growth of SKOV3 xenograft tumor was significantly inhibited in 0.4 mg/kg Genistein group. Compared with control group, the tumor weights were decreased, the tumor volumes were reduced, and there was a significant increase in the area of necrosis, but no significant effects were showed on the weights of nude mice. 0.4 mg/kg Genistein (s.c.) in combination with 4 mg/kg Cisplatin (i.v.) enhanced the inhibitory effect. The results provide evidence for the potential usefulness of Genistein in the prevention and treatment of human ovarian carcinoma.

Abstract Background: Gastric cancer is one of the most common malignancy with high mortality rate in the world. Systemic chemotherapy is thought to be an important treatment. However, due to the unsatisfactory efficiency and obvious side effects, it is urgent to detect new therapy strategy for gastric cancer. This study was aimed to investigate the effects and mechanisms of ω-3 polyunsaturated acids (PUFAs) combined with 5-FU on the growth of gastric cancer cells in nude mice. Methods: BALB/C nude mice were injected subcutaneously with SGC7901 gastric cancer cells to establish a tumor-bearing mouse model. The tumor growth in vivo was observed. Morphological of tumor specimens was observed by HE staining. The mRNA levels of RhoA, RhoC and ROCK1 in tumor tissues were detected by qPCR, and their protein levels were detected by immunofluorescence and Western Blot. Meanwhile, apoptosis –related proteins were also determined by Western Blot.Results: Compared with the NC control group, the tumor volume and weight in ω-3 PUFAs and 5-Fu groups were insignificantly lower, but significantly lower in the combination group. Compared with the abundant blood supply in the NC group, HE staining showed multifocal tumor necrosis in the three intervention groups, and this change was the most prominent in the combination group. And qPCR results showed that the mRNA levels of RhoA in the combination groups were significantly lower than this in the other groups. Immunofluorescence showed that the level of RhoA protein in the three intervention groups decline in varying degrees, especially in the combination group. Western Blot showed that the protein level of RhoA in the three intervention groups were significantly lower than those in the NC control group, especially in the combination group. Meanwhile, the protein level of ROCK1 in both 5-FU group and the combination group were significantly lower, especially in the combination group. Compared with the control group, the levels of Bcl-2 and Caspase-9 decreased in the combination group, the level of cleaved Parp was increased at the same time.Conclusion: ω-3 PUFAs combined with 5-FU may inhibit tumor growth through the Rho/ROCK pathway and promote apoptosis by down-regulating the levels of Bcl-2 and Caspase-9 and induce the increase of cleaved Parp level.

Ovarian cancer has high mortality and delayed diagnosis. Inflammation is considered as a risk for ovarian carcinoma, and it contributes to all grades of tumour progression. Inflammation involved in the development of cancer cell and can be caused by an increase in the formation of pro-inflammatory cytokines. This research was conducted to assess serum Interleukin, Gonadotropins hormone and Steroid hormone levels in ovarian cancer patients and to assess their impact in disease action. The present study is composed of 85 women (mean age = 62.03±12.4 yrs) with clinically and pathologically confirmed ovarian cancer and 65 healthy women as a control group (mean age = 61±12.1 yrs). The measured biochemical parameters included: the level of serum gonadotropins(LH, luteinizing hormone; FSH, follicle-stimulating hormone), steroid hormones (estrogen, progesterone, prolactin, testosterone) and Interleukin (IL-4, IL-6, and IL-8). The results demonstrated significantly high values of steroid hormones (p<0.01, p<0.01, p<0.05,p<0.002, p<0.01 (estrogen, progesterone, prolactin, testosterone) and significantly high ( p<0.001, p<0.002, p<0.01)values in (IL-4, IL-6, and IL-8) in ovarian cancer in comparison with control group. There were also significantly high (p<0.0001, p<0.05 values of sera LH and FSH in women ovarian cancer in comparison with the control group. p<0.01, p<0.001) respectively in ovarian cancer in comparison with the control group. An elevation of serum steroid hormone, gonadotropins, and Interleukin levels in cases of ovarian carcinoma in our study is important as a marker of the disease.

Abstract Background: Inhibitory effect of endostar combined with radiotherapy on gastric cancer (GC) animal models and its effect on transforming growth factor-β1 (TGF-β1) and inter- leukin-10 (IL-10) were evaluated. Methods: Forty mice of a GC model xenograft tumors were prepared and randomly divided into blank control group, endostar group, radiotherapy group and endostar combined with radiotherapy group (combination group). From the 14th day, a vernier caliper was used for measuring the long and short diameters of the xenograft tumors. The formula V = ab2/2 was used for calculating the tumor volume and to obtain its average value. Tumor growth curves were plotted to calculate the tumor inhibition rate. The growth of xenograft tumors and the behavioral changes of mice were observed. Enzyme-linked immunosorbent assay (ELISA) was used for detecting the expression levels of IL-10 and TGF-β1. Results: The tumor growth in the combination group was significantly inhibited and the tumor volume was the smallest compared with the other groups (p<0.05). Compared to the blank control group, the tumor inhibition rate was 11.8% in endostar group, 33.0% in radiotherapy group and 52.1% in combination group (p<0.01). Endostar combined with radiotherapy had an interaction in decreasing the expression levels of TGF-β1 and IL‑10 (F=4.35 and 5.12, p<0.05). Leucocyte count was significantly higher in control and combination groups than that in endostar and radiotherapy groups. The body weight of mice in endostar and radiotherapy groups decreased after treatment (p<0.05). The body weight of mice after treatment in control and combination groups increased, with a statistically significant difference compared to that before treatment (p<0.05). There was a statistically significant difference among all groups after treatment (F=198.1, p<0.01). Conclusions: Endostar combined with radiotherapy can inhibit tumor growth and downregulate the expression levels of TGF-β1 and IL-10 through synergistic action.

Theaflavin-3,3′-digallate (TF3) is a unique polyphenol in black tea. Epidemiological studies have proved that black tea consumption decreases the incidence rate of ovarian cancer. Our former research demonstrated that TF3 inhibited human ovarian cancer cells. Nevertheless, the roles of checkpoint kinase 2 (Chk2) and p27 kip1 (p27) in TF3-mediated inhibition of human ovarian cancer cells have not yet been investigated. In the current study, TF3 enhanced the phosphorylation of Chk2 to modulate the ratio of pro/anti-apoptotic Bcl-2 family proteins to initiate intrinsic apoptosis in a p53-independent manner and increased the expression of death receptors to activate extrinsic apoptosis in OVCAR-3 human ovarian carcinoma cells. In addition, TF3 up-regulated the expression of p27 to induce G0/G1 cell cycle arrest in OVCAR-3 cells. Our study indicated that Chk2 and p27 were vital anticancer targets of TF3 and provided more evidence that TF3 might be a potent agent to be applied as adjuvant treatment for ovarian cancer.

Lung cancer and its related cachexia are the leading cause of cancer death in the world. In this study, we report the inhibitory effect of the combined therapy of Astragalus membranaceus and Angelica sinensis, on tumor growth and cachexia in tumor-bearing mice. Lewis lung carcinoma cells were inoculated into male C57BL/6 and CAnN.Cg-Foxn1nu nude mice. After tumor inoculation, mice were fed orally by the combination of AM and AS in different doses. In C57BL/6 mice, the combination of AM and AS significantly inhibited the growth of cancer tumor and prevented the loss of body weight and skeletal muscle. It also diminished the formation of free radicals and cytokines, stimulated the differentiation of NK and Tc cells, and rebalanced the ratios of Th/Tc cells, Th1/Th2 cytokines, and M1/M2 tumor-associated macrophages. The herbal combination also downregulated the expression of NFκΒ, STAT3, HIF-1α, and VEGF in tumors. In contrast, the findings were not observed in the nude mice. Therefore, the combination of AM and AS is confirmed to inhibit the progression of lung cancer, cancer cachexia, and cancer inflammation through the immunomodulatory function.
