Background. The formulation of Bu Shen Yang Xue (BSYX) has been clinically used in treating gynecologic disease in China, especially for the development of the endometrium. Endometrial carcinoma is the most common malignant tumor of the female genital tract in developed countries. And few studies have been reported on the antitumor activity of BSYX. Therefore, this study aimed to investigate the effect of BSYX on endometrial cancer and make an initial discussion of the underlining mechanisms in Ishikawa cells. Methods and Results. Firstly, 60 SPF female nude mice were randomly divided into control group, model group, BSYX group, and positive group. The models of subcutaneous tumor xenograft of nude mice were established by injection of human endometrial carcinoma cell line Ishikawa tumor cell suspension. Compared with model group, BSYX reduced effectively tumor volume and changed pathological feature in mice tumor issue. Meanwhile, proteins from tumor issues were detected by western blot analysis. The protein levels of follicle-stimulating hormone receptor (FSHR), p-Akt/Akt, Gankyrin, and cyclinD1 in the model group were higher than those in control group but the expression in BSYX group was lower than that in the model group. The hypoxia inducible factor alpha (HIF-α) protein level in the model group was lower than those in control group and upregulated in BSYX group. In addition, Ishikawa cells were cultured and then exposed to follicle-stimulating hormone (FSH), LY294002, a highly selective PI3K inhibitor and serum containing BSYX, respectively. LY294002 and BSYX markedly decreased the cancer cell viability and migration ability and increased the apoptosis rate. FSH promoted the cancer cell ability and migration ability. LY294002 and BSYX evidently downregulated the proteins levels of FSHR, p-Akt/Akt, Gankyrin, and cyclinD1 and upregulated the expression of HIF-α protein, and FSH was on the opposite. Conclusions. Taken together, our results showed that the formulation of BSYX had antitumor effect on endometrial cancer in vivo and in vitro and was related with FSH/PI3K/AKT/Gankyrin/HIF-α/cyclinD1 transduction pathway.

Abstract BackgroundHepatoma is one of the most common malignant tumors in my country, and its occurrence and development play an important role in the molecular mechanism of hypoxia microenvironment and angiogenesis. Huazhengsanji prescription(HZSJ) is an empirical prescription for the treatment of liver cancer, but its specific anti-tumor molecular mechanism is still unclear, and whether it has a synergistic effect with cisplatin(DDP), a chemotherapy drug for liver cancer, has not been reported yet. This article discusses the inhibition of the proliferation and migration of HepG2 hepatocarcinoma cells and the difference in the expression of HIF-1α and VEGF when the HZSJ, DDP and the two are used in combination, and compares and analyzes the mechanism of the HZSJ in enhancing the anticancer sensitivity of chemotherapeutics.MethodsHepG2 Hepatoma cells were divided into blank control group, hypoxia model group, DDP group, HZSJ group, HZSJ+DDP group, and the hypoxia environment was induced by the CoCl2 method. MTT method detects cell proliferation ability, scratch test detects cell migration ability, immunofluorescence method and western blot detect HIF-1α and VEGF protein expression.ResultsHZSJ has the effect of inhibiting the proliferation and migration of HepG2 cells, and has obvious concentration-dependent; The combined application of HZSJ and DDP has significantly stronger inhibitory effect on cell proliferation than the HZSJ group (P<0.01) and the DDP group (P<0.01, P<0.001). High-dose HZSJ can inhibit the migration ability of HepG2 cells (P<0.01); the combination of HZSJ and DDP can significantly reduce the migration rate of HepG2 cells after induction (P<0.01, P<0.01, P <0.01). The results of immunofluorescence and western blot showed that: compared with the blank control group, the expression levels of HIF-1α and VEGF protein in the model group were significantly increased (P<0.05, P<0.01, P<0.001); compared with the model group and DDP The expression of HIF-1α protein in the high-dose HZSJ group (200μg/mL) and the combination group decreased (P<0.05, P<0.01, P<0.001), but there was no difference between the groups. Compared with the model group, the high-dose HZSJ group (200μg/mL) can reduce the expression of VEGF (P<0.05); compared with the model group and the DDP group, the combination group can reduce the expression of VEGF (P< 0.01, P<0.001), and has obvious concentration dependence.ConclusionsHZSJ can inhibit the proliferation and migration of HepG2 hepatoma cells under hypoxia, which may be related to the reduction of HIF-1α and VEGF expression, and its increase in the anticancer sensitivity of the chemotherapy drug DDP may be related to both The synergistic inhibition of VEGF expression is related.

The Impact

Objective. We aimed to observe the impact of ginkgolic acid (GA) on the proliferation and metastasis ability of ovarian cancer (OCa) cells and to further explore whether GA affects the malignant progress of OCa via regulating the lncRNA MALAT1/JAK2 axis. Methods. OCa cells SKOV3 and CAOV3 were administered with 1 ng/ml GA, 5 ng/ml GA, 10 ng/ml GA, 20 ng/ml GA, and DSMO as control, respectively. The cell proliferation and migration ability of the abovementioned cells in each group were measured by CCK-8 test and Transwell experiments. The expression levels of lncRNA MALAT1 and JAK2 protein were examined by qRT-PCR and western blot, respectively. Subsequently, in OCa cells treated with GA, lncRNA MALAT1 overexpression vector was transfected to continue to detect the proliferation activity and migration ability of each treatment group. Finally, the regulation of GA on activity of lncRNA MALAT1/JAK2 axis in OCa cells was further explored in nude mice. Results. Our data showed that the proliferation inhibition rate of cells at each ginkgolic acid concentration was higher than that of the control group ( P < 0.05 ), suggesting that GA has an inhibitory influence on the proliferation of OCa cells, in a dose-dependent way. GA was able to inhibit the proliferation rate and migration ability of OCa cells. Administration of ginkgolic acid downregulated the levels of lncRNA MALAT1 and JAK2 protein. Overexpression of lncRNA MALAT1 partially reversed the inhibited OCa proliferative capacity caused by GA treatment. Consistent with the results observed in vitro, we also found that the OCa tumor weight and volume of nude mice injected with lncRNA MALAT1 overexpression vector were enhanced and JAK2 protein level increased remarkably in comparison to the ginkgolic acid group. Conclusions. In summary, GA may exert its inhibitory effect on the proliferative and migratory capacities of OCa cells through suppressing the activity of lncRNA MALAT1/JAK2 axis.

Abstract Background Although lncRNA CTBP1-AS2 has been functionally analyzed only in cardiomyocyte hypertrophy and diabetes, analysis of TCGA dataset revealed its downregulation in endometrial carcinoma (EC), indicating its involvement in EC. Results In this study we found that CTBP1-AS2 was downregulated in EC and correlated with poor survival. MiR-216a might form base pairs with CTBP1-AS2 based on RNA-RNA interaction, which was confirmed by luciferase activity assay. Interestingly, upregulation of PTEN was observed after CTBP1-AS2 overexpression. Transwell assay showed that CTBP1-AS2 and PTEN overexpression led to decreased cancer cell invasion and migration and reduced enhancing effects of miR-216a on cell invasion and migration. It was known that miR-216a targeted PTEN. Conclusion Therefore, CTBP1-AS2 may sponge miR-216a to upregulate PTEN, thereby suppressing endometrial cancer cell invasion and migration.

265 Background: The hepatic stellate cells (HSCs) localize at the space of Disse in the liver and have multiple functions. They are identified as the major contributor to hepatic fibrosis. Some manuscripts mentioned that activated HSCs predicted prognoses of hepatocellular carcinoma. The aim of this study is to investigate the effect of HSCs and the role of IL-6 / Stat3 pathway on HCC progression. Methods: HCC cells (Hep G2 and Huh 7) were co-cultured with HSC (LX2 and Li90). The viability and migration ability of cancer cells were detected. Also, the expression of epithelial–mesenchymal transition marker (E-cadherin), stem cell marker (EpCAM and CD44), TGF-b and p-STAT3 of cancer cells were evaluated. Then the IL-6 neutralization was performed during HCC cells and HSCs co-culture. The viability and migration ability of cancer cells were detected. Also, the expression of epithelial–mesenchymal transition marker (E-cadherin), stem cell marker (EpCAM and CD44) and p-STAT3 of cancer cells were evaluated. Results: Co-culture with hepatic stellate cell increased cancer cell viability and migration ability. The expression of E-cadherin, EpCAM and CD44 of cancer cells also increased after co-culture with HSCs. The IL-6 expression and secretion of HSCs were elevated by cancer cell stimulation. The over-expressed IL-6 activated STAT3 of cancer cell showed as the level of phosphorylated STAT3 increased. Neutralized IL-6 during co-culture significantly decrease the viability and migration ability of cancer cells. Also, the expression of E-cadherin, EpCAM and CD44 of cancer cells decreased. Conclusions: HSCs might promote HCC progression through IL-6 / STAT3 pathway.

Abstract Background: Endometrial cancer is one of the most common cancers affecting women's health. The pathogenesis of endometrial cancer involves many signaling pathways which are related with transcription factors or microRNAs. Recent studies have reported that endometrial cancer is also related with the sexual-mediated hormones. The purpose of this research is to treat the endometrial cancer with the hormone-related drugs, and find out the specific molecular mechanism. Methods: In this study, RL95-2 cells and Ishikawa cells were used as the endometrial cancer cell models. miR-492 was transfected into RL95-2 cells and Ishikawa cells. The miRNA expression was measured by qRT-PCR. The protein expression was measured by western blot. Cell proliferation was monitored using the MTT assay and cell colony formation assay. Cell apoptosis was monitored using EdU assay. Results: Firstly, the results indicated that metapristone as a kind of hormone-related drugs could significantly inhibit the endometrial cancer cell growth through regulating cell apoptosis-related gene expression. Meanwhile, miR-492 was detected to be highly expressed in the endometrial cancer cell lines. Overexpression of miR-492 could promote the cell proliferation and inhibit the cell apoptosis. Furthermore, the results demonstrated that the downstream target genes of miR-492 were Klf5 and Nrf1, which were inhibited by metapristone. At the animal level, metapristone also inhibited the endometrial cancer cell growth through down-regulating the expression of miR-492 and decreasing the protein level of Klf5 and Nrf1. Conclusion: Taken together, this study indicated that metapristone inhibited the endometrial cancer cell growth through regulating the cell apoptosis related signaling pathway and the expression of miR-492 and its downstream target genes (Klf5 and Nrf1), which provided the theoretical basis of endometrial cancer in clinical treatment.

Biological behavior of HPV cell was observed by HUMSC through restraining PD-1/PD-L1 signal pathway. And HUMSC was adopted as target cell for the treatment on HPV. The rat HPV model was established and divided into three groups including blank group, control group and test group according to different reagents being injected into rats. Use HE staining method to observe the cancerous transformation of tumor tissue sections. The gene presentation of PD-1/PD-L1 and lymphocyte was detected with Western blot. The invasion and migration condition of cancer cells was observed from experiment in vitro. The quantity of cancer cells in test group was the least. And invasion and migration ability in test group was the weakest. The control group was the second. The number of tumor cells in the blank group was the largest. Strongest ability to invade and migrate. The presentation of PD-L1 was restrained partly by HUMSC. The increasing of immune-associated cells could be prompted by HUMSC. The quantity of CD3+, CD4+ and CD8+ in PB was the most in test group. The expression of blank groups is the lowest than others restrained by HUMSC. And quantity of abundant immune cells including CD3+, CD4+ and CD8+ could be activated partly through activating immune action of body. And monitoring function of immune system on HPV cells could be increased effectively. The invasion and migration ability in vitro of HPV could be reduced partly.
