The inhibitory effects of Endostar combined with chemotherapy on human esophageal squamous cell carcinoma xenograft in mice

The purpose of this study was to investigate the efficacy of Endostar combined with chemotherapy on human esophageal squamous cell carcinoma Eca-109 in mice. The tumor xenograft models were established and randomly assigned to 4 groups: control group, Endostar group (1.5?mg/kg?day, once daily for 3?weeks), chemotherapy group (Paclitaxel 10?mg/kg?day, Cisplatin 5?mg/kg?day, for 1, 7, 14, 21?days), and chemotherapy?+?Endostar group (combination). The length and width of tumor were measured and the tumor volumes (cm³) were calculated every other day. Three weeks later, the mice were executed, and the tumor tissues were collected to weigh and analyse the histopathology and proliferation for tumor xenograft. The results demonstrated that the tumor volumes and weight in chemotherapy?+?Endostar group were significantly lower than that in other three groups. Meanwhile, the cell proliferation of tumor xenograft in combined treatment group was significantly lower than that in other three groups. It was concluded that Endostar combined with chemotherapy could obviously enhance the inhibitory effect on esophageal squamous cell carcinoma Eca-109 in mice.     

Recombinant human endostatin normalizes tumor vasculature and enhances radiation response in xenografted human nasopharyngeal carcinoma models

Background

Hypoxic tumor cells can reduce the efficacy of radiation. Antiangiogenic therapy may transiently “normalize” the tumor vasculature to make it more efficient for oxygen delivery. The aim of this study is to investigate whether the recombinant human endostatin (endostar) can create a “vascular normalization window” to alleviate hypoxia and enhance the inhibitory effects of radiation therapy in human nasopharyngeal carcinoma (NPC) in mice.

Methodology/Principal Findings

Transient changes in morphology of tumor vasculature and hypoxic tumor cell fraction in response to endostar were detected in mice bearing CNE-2 and 5–8F human NPC xenografts. Various treatment schedules were tested to assess the influence of endostar on the effect of radiation therapy. Several important factors relevant to the angiogenesis were identified through immunohistochemical staining. During endostar treatment, tumor vascularity decreased, while the basement membrane and pericyte coverage associated with endothelial cells increased, which supported the idea of vessel normalization. Hypoxic tumor cell fraction also decreased after the treatment. The transient modulation of tumor physiology caused by endostar improved the effect of radiation treatment compared with other treatment schedules. The expressions of vascular endothelial growth factor (VEGF), matrix metalloproteinase-2 (MMP-2), MMP-9, and MMP-14 decreased, while the level of pigment epithelium-derived factor (PEDF) increased.

Conclusions

Endostar normalized tumor vasculature, which alleviated hypoxia and significantly sensitized the function of radiation in anti-tumor in human NPC. The results provide an important experimental basis for combining endostar with radiation therapy in human NPC.     

人重组内皮抑素辅助化疗对食管癌疗效分析

目的:评估人重组内皮抑素(endostar,ES)辅助化疗药物治疗食管癌的临床效果。方法:研究共入组128例食管癌患者,根据化疗方案将患者分为试验组与对照组,试验组患者(n=60)进行5个疗程ES联合化疗,每个化疗疗程持续3周,静脉注射ES 15mg/d。对照组患者(n=68)未使用ES化疗。化疗2个疗程后,手术切除肿瘤,分析肿瘤对化疗的反应。检测血管内皮生长因子(vascular endothelial growth factor,VEGF)和血小板-内皮细胞粘附分子(Platelet endothelial cell adhesion molecule-1,CD31)的表达。结果:同治疗前比较,化疗明显促进了食管癌肿瘤组织中的VEGF的表达和组织中血管的再生。两组相比,试验组患者的生存率明显提高,转移率明显降低,通过重组内皮抑素治疗显著抑制了化疗引起的VEGF的表达和微血管的生成。结论:联合重组内皮抑素化疗能够显著改善食管癌患者的临床结局。     

Recombinant Human Endostatin Endostar Suppresses Angiogenesis and Lymphangiogenesis of Malignant Pleural Effusion in Mice

Background

Malignant pleural effusion (MPE) is a common complication of lung cancer. One widely used treatment for MPE is Endostar, a recombined humanized endostatin based treatment. However, the mechanism of this treatment is still unclear. The aim of this study was to investigate the effects of Endostar in mice with MPE.

Methods and Materials

Lewis lung carcinoma (LLC) cell line expressing enhanced green fluorescent protein (EGFP) was injected into pleural cavity to establish MPE mice model. Mice were randomly divided into four groups. High dose of Endostar (30 mg/kg), low dose of Endostar (8 mg/kg), normal saline, or Bevacizumab (5 mg/kg) was respectively injected into pleural cavity three times with 3-day interval in each group. Transverse computed tomography (CT) was performed to observe pleural fluid formation 14 days after LLC cells injection. Mice were anesthetized and sacrificed 3 days after final administration. The volume of pleural effusion n was measured using 1 ml syringe. Micro blood vessel density (MVD), Lymphatic micro vessel density (LMVD), the expression level of vascular endothelial growth factor A (VEGF-A) and VEGF-C were observed by immunohistochemistry (IHC) staining.

Results

The volume of pleural effusion as well as the number of pleural tumor foci, MVD and the expression of VEGF-A were significantly reduced in high dose of Endostar treat group. More importantly, LMVD and the expression of VEGF-C were markedly lower in treat group than those in the other three control groups.

Conclusion

Our work demonstrated that Endostar played an efficient anti-cancer role in MPE through its suppressive effect on angiogenesis and lymphangiogenesis, which provided a certain theoretical basis for the effectiveness of Endostar on the MPE treatment.     

Comprehensive Evaluation of the Anti-Angiogenic and Anti-Neoplastic Effects of Endostar on Liver Cancer through Optical Molecular Imaging

Molecular imaging enables non-invasive monitoring of tumor growth, progression, and drug treatment response, and it has become an important tool to promote biological studies in recent years. In this study, we comprehensively evaluated the in vivo anti-angiogenic and anti-neoplastic effects of Endostar on liver cancer based on the optical molecular imaging systems including micro-computer tomography (Micro-CT), bioluminescence molecular imaging (BLI) and fluorescence molecular tomography (FMT). Firefly luciferase (fLuc) and green fluorescent protein (GFP) dual labeled human hepatocellular carcinoma cells (HCC-LM3-fLuc-GFP cells) were used to establish the subcutaneous and orthotopic liver tumor model. After the tumor cells were implanted 14∼18 days, Endostar (5 mg/kg/day) was administered through an intravenous tail vein injection for continuous 14 days. The computer tomography angiography (CTA) and BLI were carried out for the subcutaneous tumor model. FMT was executed for the orthotopic tumor model. The CTA data showed that tumor vessel formation and the peritumoral vasculature of subcutaneous tumor in the Endostar treatment group was significantly inhibited compared to the control group. The BLI data exhibited the obvious tumor inhibition day 8 post-treatment. The FMT detected the tumor suppression effects of Endostar as early as day 4 post-treatment and measured the tumor location. The above data confirmed the effects of Endostar on anti-angiogenesis and tumor suppression on liver cancer. Our system combined CTA, BLI, and FMT to offer more comprehensive information about the effects of Endostar on the suppression of vessel and tumor formation. Optical molecular imaging system enabled the non-invasive and reliable assessment of anti-tumor drug efficacy on liver cancer.

Endostar Combined with Gemcitabine and Cisplatin Chemotherapy for Patients with Metastatic Nasopharyngeal Carcinoma: an Update

OBJECTIVE: A previous phase-2 trial to assess the addition of Endostar to gemcitabine and cisplatin (GC) chemotherapy showed that it improves prognosis in metastatic nasopharyngeal carcinoma (M-NPC) but the study cohort was small. We wished to update that phase-2 trial by enrolling an additional 44 patients and to assess the benefit of Endostar+GC chemotherapy. METHODS: An analysis of 72 M-NPC patients treated between July 2010 and November 2016 was done. The treatment regimen was a combination of gemcitabine (1,000 mg/m²) on days 1 and 8, cisplatin (80 mg/m²) on day 1, and Endostar (15 mg/day) from day 1 to day 14 of a 21-day cycle for ≥2 cycles. The acute toxic effects and therapeutic efficacy were analyzed. RESULTS: The response rate was 77.8%. The median progression-free and overall survivals were 12 and 19.5 months, respectively. A total of 329 cycles of GC and 288 cycles of Endostar were delivered to 72 patients, with the median number of four (range, 2–10) cycles administered per patient. The main grade-3/4 hematologic toxicities were leukopenia (54.1%) and neutropenia (59.8%). The number of non-hematologic adverse events was minimal. The regimen was well-tolerated. CONCLUSIONS: Endostar+GC chemotherapy is an effective, well-tolerated regimen for M-NPC.

Endostar suppresses invasion through downregulating the expression of matrix metalloproteinase-2/9 in MDA-MB-435 human breast cancer cells

Endostar, a novel recombinant human endostatin expressed and purified in Escherichia coli with an additional nine-amino acid sequence forming another his-tag structure, was approved by the State Food and Drug Administration of China (SFDA) in 2005 for the treatment of non-small-cell lung cancer. However, the molecular mechanism of its potent anticancer activity remains poorly understood and warrants further investigations. In this study, we examined the anti-invasive activities of endostar in vitro. The results showed that endostar suppressed MDA-MB-435 cell adhesion to the fibronectin-coated substrate in a concentration-dependent manner. It could inhibit the wound healing migration of MDA-MB-435 cells and invasion of MDA-MB-435 cells through reconstituted ECM (matrigel). Zymography revealed that endostar decreased the secretion of MMP-2 and MMP-9. Endostar could also inhibit the expressions of MMP-2 and MMP-9 in MDA-MB-435 cells. Additionally, endostar exerted an inhibitory effect on the phosphorylation of ERK1/2. Collectively, these data provided a molecular basis for the anti-invasive effects of endostar.
