Inhibitory effect of ginsenoside Rg3 on ovarian cancer metastasis

Background Ginsenosides are main components extracted from ginseng, and ginsenoside Rg3 is one of the most important parts. Ginsenoside Rg3 has been found to inhibit several kinds of tumor growth and metastasis. The present study was undertaken to investigate the effect of ginsenoside Rg3 on human ovarian cancer metastasis and the possible mechanism. Methods The experimental lung metastasis models of ovarian cancer SKOV-3 and the assay of tumor-induced angiogenesis were used to observe the inhibitory effects of Rg3 on tumor metastasis and angiogenesis. The effect of Rg3 on invasive ability of SKOV-3 cells in vitro was detected by Boyden chamber, and immunofluorescence staining was used to recognize the expression of matrix metalloproteinase 9 （MMP-9） in SKOV-3 cells. Results In the experimental lung metastasis models of ovarian cancer, the number of tumor colonies in the lung and vessels oriented toward the tumor mass in each ginsenoside Rg3 group, was lower than that of control group. The invasive ability and MMP-9 expression of SKOV-3 cells decreased significantly after treatment with ginsenoside Rg3. Conclusions Ginsenoside Rg3 can significantly inhibit the metastasis of ovarian cancer. The inhibitory effect is partially due to inhibition of tumor-induced an qioqenesis and decrease of invasive ability and MMP-9 expression of SKOV-3 cells.     

Effect of recombinant human endostatin on endometriosis in mice

Background Direct and indirect evidences have suggested that angiogenesis is a prerequisite for the development of endometriosis. Aiming at offering experimental evidences for anti-angiogenesis therapy, we transplanted the eutopic endometrium from patient with endometriosis into the severe combined immunodeficiency disease (SCID) mice, to evaluate the effect of the endostatin on the growth and angiogenesis of the established endometriosis lesions in SCID mice model.Methods Eutopic endometrium of women with endometriosis was transplanted into the SCID mice. The mice were randomized into treatment (n=10) and control groups (n=10). Two weeks after the implantation of endometrium fragment, the treatment group was injected with recombinant human endostatin YH-16 into the peritoneal cavity (2 mg·kg(-1)·d(-1)), whereas the control group received equivalent volume of PBS (200 µl/d). The volume of endometriotic lesions in SCID mice was measured every three days, and all the treatment lasted for 14 days. Immunohistochemistry was used to determine microvessel density (MVD) and the expression of VEGF. The results were analyzed by t test and χ(2) test to value the treating effect. Results Compared with the control group, growth of endometriosis lesion was reduced in the mice treated with YH-16. Statistically significant differences in the volume and weight of the ectopic lesions were observed between the treatment and the control groups (P<0.05). Microscopical examination showed that after being treated with YH-16, the volume of the endometrial tissues decreased, the glands depauperated, and the glandular epithelium partially degenerated. Necrotic debris was observed in the endometrial stroma. MVD and expression of VEGF in the treatment group were significantly lower than those in the control group (P<0.05). Conclusions Recombinant human endostatin affects the maintenance and growth of endometriotic tissues by inhibiting angiogenesis and reducing the expression of VEGF in ectopic lesion. The angiostatic agent may be promising as a therapy for endometriosis.     

Exploration on Effect and Mechanism of Suiqing Pill (髓清丸) on Tumor Angiogenesis in Nude Mouse B16 Melanoma Model

Objective: To study the effect of Suiqing Pill (SQP, 髓清丸),a TCM compound drug that can activate blood circulation and get rid of blood stasis, on angiogenesis in tumor and its possible mechanism. Method: BALB/c nude mice were inoculated with melanoma cell line B16 at right armpit subcutaneously to establish cancer spontaneous metastasis model. Levels of microvessel density (MVD), vascular endothelial growth factor (VEGF) and protein expression of matrix metalloproteinase-2 (MMP-2) in tumor tissues were observed and compared. Results: Strong expression of anti-Factor Ⅷ (FⅧ) related antigen and plentiful tumor angiogenesis were seen in model control animals, while in the high-dose and low-dose SQP treated model mice, MVD was inhibited by 33. 5% and 22. 6% respectively ( P<0. 01, P<0. 05). The strong positive protein expression of VEGF and MMP-2 in model control also reduced in the SQP treated groups.

Effect of Antisense Oligodeoxynucleotide of Vascular Endothelial Growth Factor C on Lymphangiogenesis and Angiogenesis of Pancreatic Cancer

In order to investigate the effect of antisense oligonucleotide (ASODN) of vascular en-dothelial growth factor C (VEGF-C) on lymphangiogenesis and angiogenesis of pancreatic cancer, antisense and scamble-sense oligonucleotide of VEGF-C were constructed, and the model of nude mice with orthotopically xenografted human pancreatic cancer cells (Panc-1) was established. Thirty nude mice were randomly divided into 3 groups: PBS control group (group A), scramble-sense con-trol group (group B) and antisense group (group C). All nude mice were treated once every 2 days as 3 times per week, for 3 weeks (oligonucleotide 10 mg/kg every time). After treatments were com-pleted, ELISA method was used to examine the concentration of VEGF-C in plasma and immunohis-tochemical method to examine microvessel density (MVD), lymphtic vessel density (LVD) of pan-creatic cancer. The results showed that the expression of VEGF-C was inhibited significantly in group C. The concentrations were 237.5±41.5, 221.5±52.3 and 108.6±14.9 pg/mL in groups A, B and C re-spectively (P<0.01). LVD in groups A, B and C was 13.8±2.1, 12.4±1.9 and 4.2±1.6 respectively (P<0.01). MVD in groups A, B and C was 27.5±8.7, 25.9±4.2 and 19.4±5.6 respectively with no sig-nificant difference among the groups (P>0.05). It was suggested that VEGF-C ASODN decreased the expression levels of VEGF-C in nude mice with orthotopically xenografted human pancreatic cancer, and it could inhibit lymphangiogenesis, but had no significant effect on angiogenesis.

Effects of angiotensin-converting enzyme inhibitors and angiotensin II type 1 receptor blockers on lymphangiogenesis of gastric cancer in a nude mouse model

Background Angiotensin-converting enzyme inhibitors （ACEI） and angiotensin II type 1 receptor blockers （ARB） can inhibit tumor growth by inhibition of angiogenesis. This study was designed to study the anticancer effects of ACEI and ARB on tumor growth and lymphangiogenesis in an implanted gastric cancer mouse model. Methods A model of gastric cancer was established by subcutaneously inoculating human gastric cancer cell line SGC-7901 into 60 nude mice. One week later, all mice were randomly divided into 5 groups. A control group received physiologic saline once daily for 21 days. Mice in the 4 treatment groups received one of the following agents by gavage once daily for 21 days： perindopril, 2 mg/kg; captopril, 5 mg/kg; Iosartan, 50 mg/kg; or valsartan, 40 mg/kg. Twenty-one days after treatment, all the mice were sacrificed and the tumors were removed. Tumor sections were processed, and immunohistochemical methods were used to observe the expressions of vascular endothelial growth factor C （VEGF-C）, matrix metalloproteinase 7 （MMP-7）, and lymphatic microvessel density （LMVD）.
Results Tumor volume was significantly inhibited in all ACEI and ARB groups, compared with the control group （all P 〈0,01）. LMVD in the ACEI and ARB groups was also significantly lower than that of the control group （all P 〈0.01）. In the ACEI groups, the expressions of VEGF-C and MMP-7 were both significantly decreased, compared with the control group （all P 〈0.05）. In the ARB groups, expression of VEGF-C was significantly decreased compared with the control group （all P 〈0.05）. However, no significant difference was found in the expression of MMP-7 between ARB groups and the control group.
Conclusion In a mouse model, ACEI and ARB might inhibit gastric cancer tumor growth by suppressing lymphangiogenesis.     

Effects of cloned tumstatin-related and angiogenesis-inhibitory peptides on proliferation and apoptosis of endothelial cells

Background Tumstatin is a recently developed endogenous vascular endothelial growth inhibitor that can be applied as an anti-angiogenesis and antineoplastic agent. The study aimed to design and synthesize the small molecular angiogenesis inhibition-related peptide （peptide 21）, to replicate the structural and functional features of the active zone of angiogenesis inhibition using tumstatin and to prove that synthesized peptide 21 has a similar activity： specifically inhibiting tumor angiogenesis like tumstatin. Methods Peptide 21 was designed and synthesized using biological engineering technology. To determine its biological action, the human umbilical vein endothelial cell line ECV304, the human ovarian cancer cell line SKOV-3 and the mouse embryo-derived NIH3T3 fibroblasts were used in in vitro experiments to determine the effect of peptide 21 on proliferation of the three cell lines using the MTT test and growth curves. Transmission electron microscopy （TEM） and flow cytometry （FCM） were applied to analyze the peptide 21-induced apoptosis of the three cell lines qualitatively and quantitatively. In animal experiments, tumor models in nude mice subcutaneously grafted with SKOV-3 were used to observe the effects of peptide 21 on tumor weight, size and microvessel density （MVD）. To initially investigate the role of peptide 21, the effect of peptide 21 on the expression of vascular endothelial growth factors （VEGFs） by tumor tissue was semi-quantitatively analyzed. Results The in vitro Ml-r test and growth curves all indicated that cloned peptide 21 could specifically inhibit ECV304 proliferation in a dose-dependent manner （P 〈0.01）; TEM and FCM showed that peptide 21 could specifically induce ECV304 apoptosis （P 〈0.01）. Results of in vivo experiments showed that tumors in the peptide 21 group grew more slowly. The weight and size of the tumors after 21 days of treatment were smaller than those in the control group （P 〈0.05）, with a mean tumor inhibition rate of 67.86%; MVD
